CLOSER:AI is your personal sales gym—practice real conversations, sharpen your pitch, and close with more confidence. Whether you’re new to selling or refining your next big deal, CLOSER:AI gives you a safe space to rehearse objections, closing techniques, and negotiations with intelligent AI partners that push back like real prospects. WHY CLOSER:AI? Most sales skills are built in the field—but the field is unforgiving. CLOSER:AI lets you fail forward: run unlimited practice sessions, get structured feedback after every call, and track your improvement over time. No awkward role-plays with coworkers. No waiting for a manager to be free. Just open the app and train. LIVE SALES SIMULATIONS Choose from realistic training scenarios across objection handling, closing, and negotiation—from “too expensive” and “not interested” to “I need to think about it,” same-day closes, and bundle negotiations. Each scenario is designed to mirror pressure you’ll face on real calls. Pick your AI partner and jump into a live chat simulation. Respond naturally, handle pushback, and work toward a positive outcome. When you’re ready, end the session and receive AI-generated feedback with a session score, skill breakdown, strengths, weaknesses, and actionable suggestions you can apply on your next call. YOUR AI SALES COACH Have a question between sessions? Ask AI anything about selling—objection handling, closing scripts, negotiation tactics, or strategy for your next deal. Get instant, practical answers in a dedicated coaching chat. Optional read-aloud replies and voice input let you practice the way you actually sell: by talking, not only typing. TRACK YOUR PROGRESS Stay motivated with a clear view of your training journey: • Total completed sessions • Average and best session scores • Daily practice streaks • Score trends over recent sessions • Weekly averages and improvement insights See what’s working, spot patterns, and keep pushing your numbers higher—one rep at a time. BUILT FOR BUSY SALES PROFESSIONALS • Clean, focused interface—train in minutes, not hours • English and German language support • Secure account with profile, password, and account management • In-app support and feedback • Privacy policy, terms, and account deletion available in-app WHO IS IT FOR? CLOSER:AI is ideal for: • SDRs and AEs building foundational skills • Account executives preparing for tough negotiations • Founders and solo sellers who sell their own product • Sales teams who want extra reps outside live coaching • Anyone who wants to practice before the real conversation HOW IT WORKS 1. Create your account and sign in 2. Pick a scenario that matches your challenge 3. Choose your AI partner and run a live simulation 4. End the session to receive detailed feedback 5.
