Sleak is an AI-powered coaching platform that helps enterprise teams build business-critical skills through realistic conversation practice. Instead of static courses, Sleak's AI Coach teaches through personalized dialogue, trains through voice-based roleplay simulations with virtual counterparts, and scores performance against custom rubrics (scorecards) with evidence cited from the transcript. Managers launch initiatives instead of assigning courses: they define what a team needs to know (product knowledge, methodology, objection handling) and do (negotiate, give feedback, close deals), and the AI Coach builds and delivers the training automatically. Product Sleak's platform is built around three core products: 1 . Knowledge Coach: a dialogue-based coaching experience where the AI Coach explains concepts, answers questions, and transfers knowledge conversationally, so teams build understanding of products, methodology, and strategy without sitting through a static course. 2. AI Roleplay (KI-Rollenspiele): realistic, voice-based simulations with virtual counterparts (personas) that let learners practice high-stakes conversations, such as negotiations, objection handling, or difficult feedback, in a private, repeatable setting. Every session is scored against a custom scorecard with evidence cited from the transcript. 3. Recruiting: an extension of the platform that applies the same voice-based simulation and scoring approach to hiring, screening, and interview preparation. Use cases The platform is used across four core areas: sales, leadership, procurement, and customer service, wherever teams need to prove they can hold a business-critical conversation, not just recite the theory behind it. Common use cases include sales training, leadership development, procurement negotiation, customer success, and onboarding. Sleak is voice-native, available 24/7 via web and phone, supports 27 languages, and adapts to each learner's pace. Founded in 2024 and headquartered in Munich, Germany, Sleak serves mid-market and enterprise customers across the DACH region and beyond. * * * Seller [Sleak AI](https://www.g2.com/sellers/sleak-ai) Discussions [Sleak AI Community](https://www.g2.com/products/sleak-ai/discuss) Languages Supported Danish, German, English, French, Polish, Spanish, Swedish Overview by Philipp Heideker (Founder und CEO bei Sleak - Der Trainingsplatz für Vertriebler) Show More ## Top-Rated Alternatives [ ![Synthesia](/assets/transparent-ad5be28fbcd25b7b08d2cebe1d957125437fb5407d75ee717965ad22c8808791.gif "Synthesia") Synthesia 4.6/5(2,797) ](https://www.g2.com/products/synthesia/reviews) [ ![Mindtickle](/assets/transparent-ad5be28fbcd25b7b08d2cebe1d957125437fb5407d75ee717965ad22c8808791.gif "Mindtickle") Mindtickle 4.7/5(2,400) ](https://www.g2.com/products/mindtickle/reviews) [ ![Seismic Enablement Cloud](/assets/transparent-ad5be28fbcd25b7b08d2cebe1d957125437fb5407d75ee717965ad22c8808791.gif "Seismic Enablement Cloud") Seismic Enablement Cloud 4.6/5(1,805) ](https://www.g2.com/products/seismic-enablement-cloud/reviews) [ View All Alternatives ](https://www.g2.com/products/sleak-ai/competitors/alternatives) ## User Insights Average based on 13 real user reviews.

Mid-Market (51-1000 emp.) 4/15/2026 "Realistic simulation of sales conversations" 5/5 What do you like best about Sleak AI? I like the genuine authenticity in the sales conversations with Sleak AI. Even though it is still an AI and you keep that in mind, you notice that there is a lot behind the generated customers. Many real experiences are integrated, which directly help you practice and prepare for the next conversation. I also find that the initial setup was almost very easy, as everything was pre-configured. Review collected by and hosted on G2.com. What do you dislike about Sleak AI? This is more like, yes, too fast for me. Sometimes you need a second to give an answer. AI should wait about 5 seconds, then it asks if you're still there somehow. And that's what I would improve. It might be a bit difficult, but okay. Review collected by and hosted on G2.com. What problems is Sleak AI solving and how is that benefiting you? Sleak AI helps me practice sales conversations and provides guidance on how to properly conduct phone calls or conversations. Review collected by and hosted on G2.com.

Mid-Market (51-1000 emp.) 4/19/2026 "Efficient training tool with potential for improvement" 5/5 What do you like best about Sleak AI? I like that the customers are quite realistic, which leads to an almost genuine sales conversation. The website is very user-friendly and it loads quickly. I really like that. Review collected by and hosted on G2.com. What do you dislike about Sleak AI? So the team view is a bit buggy. When I look at the members in my team overview, I can't remove my email address without it being automatically reinserted. That's a very small thing that could surely be fixed quickly. And setting up the evaluation criteria is complex. It's also time-consuming to create the conversation types and insert the evaluation criteria. Review collected by and hosted on G2.com. What problems is Sleak AI solving and how is that benefiting you? Sleak AI makes onboarding much more efficient, saves us several hours, and increases the training volume. The customers are realistic, and the website is user-friendly and loads quickly. It enables a more objective evaluation of sales conversations. Review collected by and hosted on G2.com.

Mid-Market (51-1000 emp.) 4/15/2026 "Revolutionary training aid with AI power" 5/5 What do you like best about Sleak AI? I find Sleak AI super cool and have been using it to train my sales training for a while now. I really like it because it allows me to train without a human partner. The concept of choosing an AI as a training partner and setting the level you need is perfect. My level has improved enormously in the last few weeks, which makes me very happy. Additionally, the initial setup was super easy. The support is great, and I can really only recommend Sleak AI. Review collected by and hosted on G2.com. What do you dislike about Sleak AI? The artificial intelligence takes into account my tone of voice and the questions, but sometimes it happens that I have asked questions which are later explicitly mentioned in the evaluation as not having been asked. Review collected by and hosted on G2.com. What problems is Sleak AI solving and how is that benefiting you? Sleak AI saves me the need for a physical partner, as I can train anytime.
