ST300 | Sales Trainer 300
Live AI prospect simulations. Per-message scoring. Specific corrections.
Your reps practice the conversation, not the slides. AI personas act as realistic prospects, the AI evaluator scores every message across up to 8 metrics, and a second pass tells your reps the exact line they should have said instead. Especially built for international sales teams selling in English.
Practice the conversation, not the slides
ST300 is a live AI simulation environment. Not a video library. Not a quiz. Reps run real conversations with AI prospects, and the AI evaluator grades every message they send.
🎯 Live AI Prospect Simulation
Create AI personas that accept, reject, or negotiate the deal. Reps run the conversation in real time. The persona reacts the way a real prospect would, message by message.
📊 Per-Message Scoring Across 8+ Metrics
Every rep message is scored 0 to 10 across metrics like value proposition, qualifying, grammar, tone, and waffling. Define your own metrics for your industry, your buyers, your stage of the funnel.
✏️ The Exact Line They Should Have Said
After the simulation, ST300 flags the specific messages that broke down and rewrites them. Not vague feedback. The actual sentence. That is how reps build the habit, message by message.
📈 Manager Dashboards With Trend Lines
See metric trends per rep over weeks. Track accepted-deal rate across simulations. Spot which rep is slipping on qualifying or value articulation, and coach the gap directly.
🌐 Built for International Sales Teams
Grammar and tone are scored as separate metrics, so your reps see how their English actually lands with US, EU, and AU buyers. Bilingual EN/JA UI for Japan and APAC teams.
🛡️ Removes the Social Cost of Failure
In Japan and SEA, making a visible mistake in front of a manager has a social cost that does not exist in Western workplaces. AI simulation removes that cost, so reps actually practice instead of performing.
Why teams choose ST300
ST300 is the AI training platform B2B sales leaders actually trust their teams to use.
Build for sales operators
Built around the practice loop sales teams actually need. Realistic AI prospect, no audience, scored feedback, and unlimited repetition. No videos to watch, no quizzes to fill in.
Cheaper than one human coaching session
Instructor-led English and sales coaching in Japan runs ¥50,000 to ¥200,000 per employee per month at providers like Berlitz and Elan. ST300 covers the whole team for a fraction of one of those sessions.
Japan and APAC ready out of the box
Bilingual EN/JA UI, AI evaluator that scores English communication quality alongside sales technique, and trial registration that works without a sales call. Built first for non-native English speaking teams.
Direct support from the builders
Talk to the Tokyo team that designed and built ST300. No outsourced support tier between you and the people who can actually fix things.
Faster onboarding
New sales hires reach first-deal-ready in weeks, not months. Onboarding scenarios are templated, repeatable, and graded so managers know exactly when each rep is ready.
No burned leads
Reps practice on AI personas, not your real pipeline. Mistakes happen in simulation, not on calls with paying prospects.

What is ST300 and how is it different from a generic AI chatbot?
ST300 is a live AI sales simulation platform, not a chatbot. An AI persona acts as a realistic prospect that can accept, reject, or negotiate the deal. After the conversation, an AI evaluator scores every message your rep sent across configurable metrics like value proposition, qualifying, grammar, and tone, then rewrites the messages that broke down. Generic chatbots cannot grade sales conversations or track skill improvement at the team level.
Who is ST300 built for?
ST300 is built for B2B sales teams selling internationally in English, especially non-native English speaking teams in Japan and Southeast Asia. Manufacturing exporters, SaaS and tech companies, professional services, logistics, and trading companies that sell to US, EU, or AU buyers fit the ICP. Sales teams of about 3 to 50 reps see the most value.
How does ST300 score sales conversations?
Two phases. First, every message is scored 0 to 10 across up to 8 default metrics including value proposition, grammar, tone, qualifying, and waffling. Organizations can also add their own metrics. Second, ST300 returns to the conversation and flags the specific messages that broke down, with a rewritten version showing what the rep should have said instead.
Does ST300 support Japanese and Japanese business etiquette?
Yes. The UI is fully bilingual EN/JA, and the AI evaluator can score English communication quality and sales technique together. Cultural personas modeled on Japanese buyer behavior such as nemawashi, hierarchy deference, and indirect rejection are on the roadmap as a premium add-on.
How does ST300 compare to Gong or to a video LMS?
Gong analyzes real calls after the fact. ST300 trains reps before the real call so they do not lose the deal in the first place. Video LMS platforms like Allego or Lessonly are libraries of content. ST300 has nothing to watch. Reps practice. The AI grades every message and tells them what to improve.
Can we add custom evaluation metrics for our team?
Yes. ST300 ships with about 8 default metrics covering the basics of B2B sales communication. Organizations can define additional metrics specific to their industry, buyer profile, or sales playbook. The AI evaluator scores rep messages against your custom metrics on the same 0 to 10 scale.

Does ST300 work for sales teams outside Japan?
Yes. ST300 is used by B2B sales teams across APAC and globally. Full English support is available alongside Japanese, with AI personas covering common Western B2B archetypes such as CFO, procurement lead, technical evaluator, and end user. Support is provided from our Tokyo team in English and Japanese.
