Your AI product, secure from day one.

Backend, mobile, integrations, and AI workflows designed with privacy, security, and operational controls from day one.

  • 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 two-week audit to a full engineering team. Everything starts with a conversation before any paperwork.

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.

Honest about what we will not build

We tell you what we will not build. Clear scope ships faster than ambitious scope, and you hear the no before you pay for it.

You meet the actual team

The engineers on the first call are the engineers in your repo. No bait and switch, no hidden outsourcing.

  • Recorded client call

    I very much respect the knowledge that you have. You have a lot of things, just in our few communications, that no one else has mentioned. No one else has even made me think about them.

    Mirinda Scott · Founder, AI Change Mangement

  • SkinOS / 2250.care
    The team treats our roadmap like their own. Every standup felt like working with our own engineers, not an outside vendor.

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.

Book a call, or get in touch. Both routes end with a straight answer.

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.

01 / Plan a build

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.
