How we build
What every engagement gets, whatever its size: a working AI system, a schedule you can see, and a review gate nothing skips.
AI at the core, not bolted on
Frontier models with retrieval, evals and human sign-off around them. A working system, not a prompt library.
Faster where teams lose time
14 days median from first call to sprint one. Six-week sprints, a demo every week, scope in writing before the first invoice.
No AI slop. No quality trade-offs.
180+ products shipped since 2019, every one through structured review and human sign-off. 5.0 rating on verified reviews.

About Robust Devs

The engineers you meet on the first call are the engineers in your repo, the scope is in writing before the first invoice, and a median 14 days separates that call from sprint one.

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.
We build the software, systems and operations your business runs on.
Bring us the work and we will tell you what it takes, or schedule your call and talk it through first. Both routes end with a straight answer.
