Gang Rui 🚢 — CEO
Building AI without validation = expensive mistakes. I prototype and validate AI in 30 days so you know exactly what works before investing in production. Think of me as your "AI Proof of Concept Team" - I build the prototype, run the tests, hand you the blueprint. Your engineering team builds the production version. ⚒️ What you get: 📦 Working Prototype (functional demo with real data) 📊 Evaluation Framework (systematic testing, metrics, benchmarks) 📋 Production-Ready Specs (technical docs for your engineering team) 🎯 Two scenarios: 1. "Our AI isn't working" I'll prototype alternatives, test configurations, show you what works (with data). 2. "We're about to build a new AI product/feature" I'll validate feasibility before you commit 6 months of engineering resources. Why validate first: Avoid building the wrong approach. De-risk with real performance data. Get reusable evaluation systems. 🥂 Recent wins: • Hospitality Tech: Validated 97% cost savings before production build • Enterprise Platform: Tested 5 configurations, improved accuracy 25% in prototype phase • 8 years shipping products in startups (not consulting about them) My approach: ✅ Product-first: Frame from business outcomes, not just tech specs ✅ Rapid prototyping: Test what actually works ✅ Evaluation-driven: Measure everything (Braintrust, Langsmith) ✅ Clear handoff: Proven specs, not untested theories 🤝 Who I work with: • Companies/startups planning to build AI features (validate before wasting eng time) • SMEs with broken AI needing diagnosis • Consultancies needing AI prototypes for enterprise deals My writing: https://gangai.substack.com/ **Ready to validate before you build?** Free AI Audit: 20-min call - I'll tell you if your idea is worth building 📅 Book in my Featured section below **DM me if you're:** • A founder about to build AI (and want to avoid expensive mistakes) • A startup burning cash on broken AI with no idea how to fix it • An SME that wants AI but doesn't know if it'll work for your use case • A consultancy needing AI prototypes to win enterprise contracts P.S. I only work with 3 companies per month to ensure deep focus. November has 2 spots left.
