The AI Startup challenges we solve
AI demos are easy. AI products are hard.
Getting a GPT-4 demo working takes an afternoon. Building reliable, cost-efficient, production-grade AI with rate limiting, fallbacks, and evals takes experience. We've done it.
LLM costs can kill your unit economics
OpenAI tokens add up fast. We optimize prompts, implement caching, route to cheaper models for simple tasks, and monitor cost per user from day one.
AI UX is its own discipline
Streaming responses, confidence displays, hallucination handling, and user trust — AI UX requires specific patterns that general UX designers miss.
