Client Cases

Client Cases: 17 AI Projects We Have Shipped

Q: Why are you 30% cheaper than market? Is quality compromised?

Two reasons: fully remote with no office or sales-team overhead, and mature codebases across all 28 AI tracks so we never bill you to reinvent the wheel. Core members come from OpenAI, Google and top-tier Chinese tech; every delivery includes internal review plus a 60-day bug-fix warranty.

Q: Is the quote final? Any mid-project price increases?

No. Before signing we break requirements into a feature list written into the contract at a fixed all-in price. New requirements added mid-project are quoted separately and only proceed with your approval.

Q: Who owns the source code and IP?

You do, 100%. Delivery includes complete source code, deployment docs and technical docs, with the GitHub repo created under your own organization.

Q: Payment methods?

USD settlement or bank transfer. Standard schedule is 30-40-30: signing, mid-project demo, acceptance.

Q: How long does delivery take?

Validation demo in as fast as 12 hours; marketing sites 1-2 weeks, AI product MVP 4-8 weeks, private deployment or model training quoted per scope. Every project starts with a written schedule and milestone-based payments.

Q: What is the relationship between kaifaai.app and 51kaifa.app?

Sister sites: kaifaai.app builds AI products only (agents, RAG, fine-tuning, digital humans, AI MVPs — 28 directions with upfront pricing); Web3 full-stack work (chains, wallets, contracts, dApps) lives on 51kaifa.app. The two sites can cross-deliver. kaifaai.app is invested in by Chainfir Capital.

Q: How do you keep AI agent projects from going off the rails?

Every agent project ships with an eval set: accuracy, hallucination rate and refusal boundaries are all quantified, and delivery includes a reproducible quality report. An agent without evals is superstition — we don't ship superstition.

Q: Can you build small tools like an AI mock-interview app?

Yes. A validation demo takes as fast as 12 hours; single small tools are priced in the $3,800-$9,800 band. Start small, scale once it clicks.
