We build AI products for marketing, healthtech and fintech.

Only those three. Built from scratch, or taken over from whoever started them. You work with the same senior engineers from the first call to launch.

The three industries we focus on

In marketing, healthtech and fintech, the AI model is the easy part. The systems around it decide whether the product works at scale. That is what we build.

AI Marketing

AI that shows marketing teams which ads bring customers and where the budget leaks.

  • SOC 2-ready

    Controls in place before you scale

    Access, logging, change control, and incident response ready for an audit — not added after launch.

  • HIPAA-aware

    Health data handled carefully

    For healthtech and wellness teams, we design your product with the right access controls, permission systems, and PHI safeguards.

  • GDPR-aligned

    Privacy by default

    Data retention, consent, export, deletion, and vendor agreements are clearly documented across your system.

How we work together

Five ways to work together, from a five-day audit to a full engineering team. Everything starts with a conversation before any paperwork.

Typical engagement runs 6–14 weeks, scoped and priced per project. Start with a $4,999 Tech Audit.

From first call to live product

The same path from idea to production, whether you start from a blank repo or a product that already ships. Each stage lists a rough timeline and a next step.

New product. We start here.

Typical engagement · 8–14 weeks end to end

  1. Discovery

    1–2 weeks

    We map the product with you: user flows, scope, and the riskiest assumptions, before anyone writes code. You leave knowing what to build first.

    Book a discovery sprint

  2. MVP scoping

    1 week

    We cut the roadmap to the smallest launch worth shipping, priced and sequenced, so the first release earns feedback instead of burning runway.

    Estimate my build

  3. Design

    1–3 weeks

    Wireframes, a design system, and a clickable prototype, built alongside engineering so what you approve is what ships.

    See our design approach

  4. Development

    4–10 weeks

    Two-week sprints, weekly demo Looms, and CI/CD from day one. You watch it come together in your own Slack, not at a big reveal.

    How we build

  5. Deployment

    3–5 days

    We ship to your infrastructure with load tests, a security pass, and monitoring in place. Launch day stays boring.

    Our deploy stack

  6. Version & future

    Ongoing

    After launch we iterate on real usage: new features, performance, and scale, on a retainer sized to your roadmap.

A note from the founder

From the founder

I started Robust Devs in 2019 after watching too many good products die between agencies. The pattern was always the same: big promises in the sales call, silence by week six. We built this firm to be the opposite of that. A small senior team, honest scope, and the uncomfortable truth delivered early.

If you are building in marketing, healthtech, or fintech, tell me what you are working on. If we are not the right team for it, I will say so on the first call and point you somewhere better.

Frequently asked questions

  • Rarely. Most products get further by using frontier models well, with solid retrieval, evals, and UX around them. Training your own model is expensive and usually unnecessary. If your case is the exception, we will say so before any money changes hands.

Start a conversation

Two ways to start. One engineering team.

Bring a build brief or one unanswered question. Either route reaches the people doing the work.

Bring us the work.

Spend 30 minutes testing your scope, constraints, and fit. You'll know whether we're the right team and what to do next.
