Koi Labs — AI, data, and automation consulting

// What we do

Three lanes, one team.

We're hired to ship — not advise. Each engagement is scoped end-to-end and ends with a working system your team owns and operates.

AI Systems

Take a vague "we need AI in our workflow" goal and turn it into a deployed system. Spec → prototype → evaluation harness → production.

→LLM workflows + agent architectures
→Retrieval, evaluation, observability
→Working system + handoff training

Data & Knowledge Capture

Turn institutional knowledge into searchable, queryable systems before it walks out the door. Transcripts, documents, expert sessions — all decision-ready.

→Knowledge base + ingestion pipelines
→Operator-facing query interfaces
→Data plumbing + analytics that get used

Process Automation

Stop paying people to do what software should do. We build the integrations, internal tools, and automated workflows that remove the boring middle from your operations.

→Integrations across your existing stack
→Internal tools for non-technical operators
→Monitoring, alerts, and retraining

01 · Engage

Fixed-fee, milestone-billed. We scope the outcome, not the hours.

02 · Build

Spec → prototype → production. Tight loops, visible progress, working software at each milestone.

03 · Hand off

You own the code, the runbook, and the operational knowledge. Optional retainer for ongoing support.

// Recent engagements

Shipping with operators who care about outcomes

A snapshot of who we're working with right now. Industries vary; the pattern doesn't — every engagement ends with a working system in production.

Data & AI Construction-tech Estimation

Engagement details and named references available on request. Most of our clients prefer we keep their build work private until they're ready to talk about it publicly — we're the same way.

// Built for ourselves

The proof is in what we ship

Before we build for clients, we build for ourselves. These are the products we've shipped solving our own problems — relocation, AI code quality, content, and craft. They're how we earn the right to consult.

// The team

Two operators. One practice.

A small, deliberate team. We take engagements we can ship ourselves — no subcontractor chains, no offshore handoffs, no "we'll find someone."

Founder

David Koi

Georgia Tech engineer. PM at Capital One. Three-time startup founder. Currently pursuing a fine arts degree at FIT here in NYC.

I build AI-powered tools to help people solve problems I'm still figuring out myself — like relocating internationally, shipping code with confidence, and keeping track of clients who actually matter.

Partner

Alex Han

Investment banker turned smart-community builder. Serial entrepreneur. Currently building from Barcelona.

I spent seven years at Cox Communications shipping IoT infrastructure to two million homes, after starting out in investment banking at SunTrust. Outside Koi Labs, I'm building a smart-community venture and leading revenue at a fintech. At Koi Labs I lead client engagements, run the deal side, and help turn early conversations into shipped product.
