We don’t just advise health-tech companies. We’ve founded them.

Flanders Forest is a venture studio and a technical practice. We incubate and fund our own health-tech ideas, co-found with founders who bring theirs, and take fractional CTO/CPO engagements for teams that need senior technical leadership before they can hire it. Same operators, same standard — whether the equity is ours or yours.

Two ways we build

The Studio

We build companies we own a piece of.

We incubate health-tech ideas — some originated in-house, some co-founded with the person who brought them to us — contributing founding technical leadership, a team that ships, and capital where it fits the venture.

How the studio works

The Practice

We build companies you own.

Fractional CTO/CPO leadership and hands-on 0→1 execution for health-tech companies from pre-seed to Series C — including the regulated-AI and compliance work most teams can’t staff for.

Case studies - Where the clinical judgment and the code are the same judgment

A sample of the regulated AI systems, compliance-grade architecture, and 0→1 execution behind real health-tech engagements.

OpBuddy

A Billing Engine That Refuses to Guess

A pure, auditable, replayable determination engine for CMS Remote Therapeutic Monitoring billing — one that blocks a claim rather than emit an uncertain one.

Deterministic Systems & Regulatory Engineering

Otto

Making an LLM Prove Every Claim Before It Reaches a Surgeon

An operative-note generation pipeline where a language model may propose a clinical fact, but a deterministic downstream check — independent of the model — decides whether it ever reaches "populated" status.

The Studio - Sometimes the right move is to build the company ourselves.

Consulting isn’t always the right shape for a good idea. When it isn’t, we take equity instead of a fee and build alongside the founder — or become the founder.

  • Originated in-house. We generate the idea, resolve the riskiest assumption before committing engineering to it, and staff the build from our own team.
  • Co-founded with you. You bring the idea, the clinical insight, or the customer relationship. We come in as the technical co-founder — for founding equity, and capital where it fits.

The Practice - Fractional CTO/CPO leadership, and the execution to back it up.

For health-tech companies from pre-seed to Series C — from a founder who raised on an idea and needs it built, to a later-stage team making a targeted bet it doesn’t have the capacity to run alone.

  • Fractional CTO / CPO / CMO Retainer. Embedded, part-time technical and product leadership for as long as it's useful — most engagements run around a year.
  • 0→1 Build Engagement. Dedicated, hands-on execution to ship a real first version — working code, not advice from the sidelines.
  • Technical Audit / De-risking Spike. A short, scoped engagement to answer the one question a bigger bet depends on, before committing a team's budget to it.
