Sellible

Overview

In today’s highly competitive sales environment, the difference between successful and struggling sales professionals often comes down to preparation, practice, and confidence. Yet most sales teams face a fundamental paradox: the need to perfect their approach without risking valuable prospects through suboptimal performances. Enter Sellible, a groundbreaking AI-powered sales training platform that addresses this challenge through realistic, voice-based role-playing with intelligent AI buyers.

Founded in 2024 by Preet Raj, a seasoned entrepreneur with an impressive track record including founding Flyx (Google Play’s Best App of 2020), Bakstage.ai, and previous experience at Goldman Sachs, Sellible represents a new category of sales training technology. Built by NeuroNest and launched on Product Hunt in August 2025, the platform specifically addresses the unique challenges faced by founders, sales representatives, and technical professionals who need to master the art of selling without the luxury of extensive sales backgrounds or the risk of burning crucial leads during the learning process.

Rather than treating sales training as a secondary activity or relying on traditional role-playing with colleagues, Sellible positions itself as “The Sales Gym for Founders”—a dedicated environment where sales professionals can practice, fail, learn, and improve in a risk-free setting that mirrors real-world sales conversations with unprecedented accuracy and intelligence.

Key Features

Sellible distinguishes itself through a sophisticated suite of AI-powered capabilities designed to provide realistic, effective, and immediately actionable sales training:

• Advanced AI-powered sales role-play: Engages users in dynamic, unscripted sales conversations with intelligent AI buyers that respond realistically to different approaches, objections, and presentation styles. The AI adapts its behavior, personality, and objections based on industry context, buyer personas, and specific scenarios, creating genuinely unpredictable and challenging practice environments.
• Voice-native conversation interface: Provides authentic, real-time voice interactions that mirror actual sales calls, complete with natural conversation flow, interruptions, emotional nuances, and realistic buyer behaviors. This voice-first approach enables users to practice the critical verbal and tonal skills that determine sales success, from confidence and clarity to objection handling and closing technique.
• Comprehensive performance scoring and analytics: Delivers immediate, detailed scorecards after each session that analyze key sales metrics including objection handling effectiveness, value proposition clarity, discovery question quality, closing technique, and overall conversation flow. The scoring system provides both quantitative metrics and qualitative insights that enable targeted improvement.
• Psychology engine insights: Employs advanced behavioral analysis to understand buyer psychology, conversation dynamics, and emotional intelligence factors that influence sales outcomes. The psychology engine provides sophisticated feedback on buyer sentiment, engagement levels, decision-making patterns, and the psychological impact of different sales approaches and communication styles.
• Customizable buyer personas and scenarios: Allows users to practice with AI buyers tailored to specific industries, company sizes, roles, and personality types, including specialized profiles such as British buyers with authentic accents and communication styles. Users can create scenarios ranging from cold calls and discovery conversations to product demonstrations and contract negotiations.
• Safe practice environment: Provides a judgment-free zone where sales professionals can experiment with different approaches, make mistakes, and iterate on their technique without risking real prospects or damaging important business relationships. This psychological safety enables more aggressive skill development and creative problem-solving.
• Real-time conversation adaptation: The AI responds dynamically to user behavior during conversations, adjusting its responses based on the quality of questions asked, objections raised, and overall conversation direction. This creates truly interactive experiences where each conversation unfolds differently based on user performance and approach.
• Industry-specific intelligence: Incorporates deep understanding of various industries, business challenges, and buying processes to ensure practice scenarios reflect real-world complexity and buyer concerns relevant to each user’s specific market and customer base.

How It Works

Sellible operates through an intuitive yet sophisticated process designed to maximize learning effectiveness while minimizing setup complexity. The platform begins with a simple onboarding process where users either direct Sellible to their website or upload product documentation in PDF format, enabling the AI to understand their specific value proposition, product features, and typical customer challenges.

Users then select from a variety of AI buyer personas, each designed to represent different customer types, industries, personality styles, and objection patterns. These buyers are not generic simulations but carefully crafted representations of real customer archetypes, complete with authentic communication styles, industry-specific concerns, and realistic behavioral patterns. The platform includes specialized personas such as British buyers with authentic accents and cultural communication nuances, enabling practice for international sales scenarios.

The core experience centers on live, voice-based conversations that feel remarkably similar to actual sales calls. Users engage in unscripted dialogue with AI buyers who respond naturally, raise realistic objections, ask challenging questions, and exhibit the full range of behaviors encountered in real sales situations. The AI maintains context throughout conversations, remembers previous statements, and adapts its responses based on the user’s approach and effectiveness.

The platform supports multiple conversation types including discovery calls where users practice uncovering buyer needs and pain points, product demonstration scenarios where users present solutions and handle technical questions, and full sales cycle simulations that include objection handling, negotiation, and closing techniques. Each scenario can be customized for different industries, company sizes, and complexity levels.

After each conversation, Sellible’s sophisticated analysis engine provides comprehensive feedback through detailed scorecards that evaluate performance across multiple dimensions. The psychology engine analyzes conversation dynamics, buyer engagement patterns, and the effectiveness of different persuasion techniques, providing insights that go beyond simple transcript analysis to understand the psychological and emotional factors that drive sales success.

The platform tracks progress over time, enabling users to see improvement patterns, identify persistent challenges, and measure skill development across different scenario types and conversation formats. This longitudinal analysis helps users build confidence and competence systematically rather than through ad-hoc practice sessions.

Use Cases

Sellible’s sophisticated approach to AI-powered sales training makes it valuable across diverse scenarios and user types within the sales ecosystem:

• Founder sales preparation: Technical founders and entrepreneurs who must transition from product development to sales leadership can use Sellible to build confidence and competence before engaging with critical prospects, investors, or key customers. The platform enables founders to practice pitch delivery, objection handling, and value articulation in a private environment where mistakes don’t impact business outcomes.
• Sales team onboarding and development: Organizations can accelerate new hire integration by providing immediate, consistent, and scalable training that doesn’t depend on manager availability or experienced team members’ time. New sales representatives can practice fundamental skills, learn company-specific messaging, and build confidence before engaging with real prospects.
• Advanced objection handling mastery: Experienced sales professionals can use Sellible to practice handling challenging objections, competitive situations, and complex buyer concerns in a controlled environment. The AI can simulate difficult personalities, aggressive negotiation tactics, and sophisticated buyer objections that require nuanced responses and advanced selling skills.
• Presentation and pitch refinement: Sales professionals preparing for important presentations, key account meetings, or high-stakes demonstrations can use the platform to rehearse their delivery, anticipate questions, and refine their messaging based on immediate feedback and performance analysis.
• Pre-call confidence building: Before important sales calls, users can warm up with AI practice sessions that simulate similar scenarios, enabling them to enter real conversations with greater confidence, smoother delivery, and better preparation for likely objections and questions.
• Cross-cultural sales preparation: With specialized buyer personas including British accents and communication styles, international sales teams can practice adapting their approach for different cultural contexts, communication preferences, and business etiquette expectations.
• Skills assessment and coaching support: Sales managers can use Sellible as a diagnostic tool to identify individual team member strengths and development areas, providing objective data to support coaching conversations and personalized development plans.
• Competitive scenario practice: Users can practice positioning against competitors, handling competitive objections, and articulating differentiated value propositions in scenarios where AI buyers present realistic competitive challenges and alternative solution preferences.

Pros \& Cons

Understanding Sellible’s current strengths and limitations provides insight into its optimal deployment scenarios and areas for potential enhancement.

Advantages

• Authentic voice interaction experience: The platform’s emphasis on voice-native conversations provides realistic practice that closely mirrors actual sales call dynamics, including natural conversation flow, interruptions, and the need to think and respond in real-time. This authenticity translates directly to improved performance in real sales situations.
• Immediate, actionable performance feedback: Unlike traditional role-playing or generic sales training, Sellible provides instant, data-driven insights into conversation effectiveness, objection handling quality, and areas for improvement. The combination of quantitative scoring and psychological insights enables targeted skill development rather than generic coaching.
• Founder-specific design and messaging: Built specifically to address the unique challenges faced by technical founders and entrepreneurs entering sales roles, the platform understands the context of founder-led sales and provides relevant scenarios, objections, and coaching appropriate for this audience.
• Risk-free learning environment: The ability to practice, experiment, and fail without consequences enables more aggressive skill development and creative problem-solving than traditional training methods. Users can try new approaches, recover from mistakes, and build resilience in a supportive environment.
• Scalable, on-demand access: Unlike coaching sessions or traditional role-playing that requires scheduling and other participants, Sellible provides immediate access to practice opportunities whenever users need skill development or confidence building, making it highly practical for busy professionals.
• Cultural and accent diversity: The inclusion of different buyer personas with authentic accents and communication styles prepares users for international sales scenarios and diverse customer interactions that reflect real-world selling environments.

Disadvantages

• Early-stage platform maturity: As a 2024 startup with a Product Hunt launch in August 2025, Sellible is still in its early development phases and may lack the feature completeness, integration ecosystem, and proven track record of more established sales training platforms.
• Audio quality and setup requirements: Optimal performance depends on users having quality microphones, quiet environments, and stable internet connections. Poor audio setup can significantly impact the realism and effectiveness of voice-based interactions, potentially limiting accessibility for some users.
• Limited integration capabilities: Compared to comprehensive sales enablement platforms, Sellible currently offers fewer integrations with CRM systems, sales technologies, and existing training infrastructures, potentially requiring additional tools or manual processes to integrate insights into broader sales workflows.
• Single-founder development constraints: With LinkedIn indicating “1 employee” and the platform being developed primarily by founder Preet Raj, the speed of feature development, user support responsiveness, and platform evolution may be limited compared to larger development teams.
• Specialized use case focus: While the founder-specific focus is a strength, it may limit applicability for large sales organizations, complex enterprise sales processes, or teams that need broader sales training coverage beyond role-playing and conversation skills.

How Does It Compare?

To understand Sellible’s position in the rapidly evolving 2025 AI sales training landscape, it’s essential to examine how it differs from both established platforms and emerging specialized solutions across different categories of sales training and enablement.

Second Nature AI has established itself as a pioneer in AI-powered sales role-play, offering avatar-based learning experiences combined with conversational training capabilities. While Second Nature provides a polished, comprehensive platform with structured learning paths and extensive customization options, it operates primarily through avatar interactions rather than pure voice conversation. Sellible differentiates itself by focusing exclusively on voice-native experiences that more closely mirror real phone-based sales conversations, making it particularly valuable for teams that conduct business primarily through voice calls rather than video meetings.

Hyperbound specializes specifically in dynamic, voice-based conversation simulation designed for realistic sales practice. While both Hyperbound and Sellible focus on voice interactions, Hyperbound emphasizes sophisticated conversation branching and unlimited scenario variations, targeting larger sales teams with complex training needs. Sellible’s strength lies in its founder-specific focus and immediate accessibility, making it more suitable for individual practitioners and smaller teams who need quick, effective practice without extensive setup or customization requirements.

Gong.io dominates the conversation intelligence and post-call analysis market, providing comprehensive insights into sales call performance, deal health, and team analytics. However, Gong operates as a reactive analysis tool that helps understand what happened after conversations occur, while Sellible serves as a proactive training tool that improves performance before conversations happen. The platforms complement each other perfectly—Gong for analysis and coaching based on real calls, Sellible for skill development and confidence building before important conversations.

Virti offers AI role-play training through virtual humans and immersive learning environments, serving broader training applications beyond sales. While Virti provides sophisticated avatar technology and detailed analytics, its general-purpose design means less specialized focus on sales-specific scenarios and founder challenges. Sellible’s targeted approach to sales training and founder needs provides more relevant scenarios and feedback for sales-specific skill development.

Salesably positions itself as a comprehensive AI sales training platform combining role-play scenarios with learning management and content creation capabilities. While Salesably offers broader feature coverage including automated content generation and knowledge testing, Sellible excels in conversation realism and immediate accessibility. Salesably targets larger organizations needing comprehensive training infrastructure, while Sellible serves practitioners who want immediate, high-quality conversation practice.

Wonderway provides AI-driven sales coaching with automatic call scoring and feedback based on real sales conversations. Like Gong, Wonderway focuses on analyzing actual sales calls to provide coaching insights, making it complementary to rather than competitive with Sellible’s pre-call training approach. Teams using Wonderway for post-call analysis often benefit from Sellible’s pre-call practice to improve the conversations being analyzed.

Awarathon offers conversational AI for sales training with interactive simulations and instant feedback. While both platforms provide AI-powered conversation practice, Awarathon focuses more on structured training programs and certification pathways, while Sellible emphasizes immediate practice access and founder-specific scenarios. Awarathon suits organizations with formal training programs, while Sellible serves individual practitioners needing quick skill development.

GTMbuddy provides AI-powered sales enablement combining training, coaching, and performance analytics in a comprehensive platform. While GTMbuddy offers broader coverage including content management and team analytics, Sellible’s specialized focus on conversation practice provides superior training realism for voice-based selling skills. GTMbuddy targets revenue operations teams, while Sellible serves front-line practitioners.

Spekit delivers real-time sales enablement and knowledge management integrated directly into sales workflows and CRM systems. While Spekit excels in providing contextual information and guidance during actual sales activities, Sellible focuses on skill building before those activities occur. The platforms serve different stages of the sales process—Spekit for in-the-moment support, Sellible for advance preparation.

Mindtickle offers a comprehensive sales readiness platform combining training, coaching, and performance management for large sales organizations. While Mindtickle provides extensive feature coverage and enterprise-grade capabilities, its complexity and implementation requirements make it unsuitable for individual practitioners or small teams. Sellible’s simplicity and immediate accessibility provide effective training for users who don’t need enterprise-scale platforms.

Sellible’s unique positioning lies in its combination of voice-native realism, founder-specific focus, and immediate accessibility without the complexity, setup requirements, or enterprise focus that characterizes many competitive platforms. Rather than competing on feature breadth or comprehensive coverage, Sellible excels at delivering authentic conversation practice that directly translates to improved sales performance.

This specialized approach makes Sellible particularly valuable for technical founders transitioning to sales roles, individual sales practitioners seeking skill improvement, and small teams that need effective training without extensive platform management overhead. The voice-first design and AI sophistication provide training realism that generic role-playing or text-based simulations cannot match, while the founder-focused scenarios and feedback address specific challenges that broader platforms often overlook.

Final Thoughts

Sellible represents a significant advancement in AI-powered sales training, addressing a fundamental gap between theoretical sales knowledge and practical conversation skills that determine real-world success. In an era where founders must increasingly serve as their companies’ primary sales leaders and where sales teams face ever-increasing pressure to perform immediately, platforms like Sellible that provide safe, realistic practice environments become essential competitive advantages.

The platform’s founder-specific focus demonstrates sophisticated understanding of a crucial but often overlooked market segment. Technical founders and entrepreneurs face unique challenges when transitioning from product development to sales leadership, often lacking both the experience and confidence needed to effectively communicate value propositions, handle objections, and close deals. Sellible’s specialized approach to these challenges, combined with its voice-native design and immediate accessibility, creates genuine value for this underserved audience.

The August 2025 Product Hunt launch timing positions Sellible well within the rapidly expanding AI sales training market, where demand for realistic, intelligent practice environments continues to grow as traditional training methods prove insufficient for modern selling complexity. The platform’s emphasis on voice interactions addresses a critical limitation of many AI training tools that focus primarily on text or avatar-based interactions, missing the verbal and tonal skills that determine sales conversation success.

However, Sellible’s early-stage status and single-founder development model create both opportunities and risks. While the focused development approach enables rapid innovation and direct customer feedback integration, it also raises questions about long-term platform scalability, feature development speed, and competitive sustainability as larger, better-funded platforms enter the market.

For founders, sales representatives, and small teams seeking immediate improvement in sales conversation skills, Sellible offers compelling value through its combination of realistic practice environments, sophisticated feedback mechanisms, and specialized focus on founder challenges. The platform’s voice-native approach and psychology-driven insights provide training realism that directly translates to improved performance in actual sales situations.

The 50% discount promotion for Product Hunt users and three free practice sessions without signup requirements demonstrate smart customer acquisition strategies that reduce adoption barriers while enabling users to experience the platform’s value before committing to paid plans. This approach reflects understanding of the sales training market’s skepticism toward new solutions and the need to prove value quickly.

As the AI sales training landscape continues to evolve rapidly, platforms like Sellible that focus on specialized use cases and superior user experiences may have advantages over comprehensive solutions that attempt to serve all training needs but excel at none. The key to Sellible’s long-term success will be maintaining its focus on conversation realism and founder-specific value while gradually expanding capabilities and market coverage without losing the specialized advantages that differentiate it from broader competitors.

For sales professionals ready to move beyond theoretical training toward practical skill development, Sellible provides an innovative solution that addresses the fundamental challenge of building sales confidence and competence without risking valuable prospects. The platform’s emphasis on voice-based practice, immediate feedback, and psychological insights positions it as a valuable tool for anyone serious about mastering the art and science of effective sales conversations.
