KVB Development / Est. MMXIX San Francisco × Lisbon

We build the
software your
roadmap depends on.

KVB is a small senior studio. We embed with technical teams to design, ship and operate production software — from architecture to on-call. We write the code. We carry the pager. No slides.

Response to brief

A senior team that writes
the software, and then runs it.

From greenfield builds to legacy modernization, AI engineering to cloud operations. Six disciplines below; ten on the catalog page.

Opinionated, but
not dogmatic.

Boring technology where it earns its place. Novel technology where it unlocks a 10×. We’ll always tell you which is which — and why we chose what we chose.

Senior-only.
Small by design.

No bench, no farm-out, no “junior we’re training” on your bill. The same people who scope your work ship it.

A predictable shape
around messy work.

Four phases. Two-week cadence. One Slack channel. We don’t reinvent delivery for each client — we just execute it harder.

01 / Discovery

One-week sprint

Senior engineer and designer in the room. Outcome: a written architecture, risk register, milestone plan you own forever.

02 / Foundation

Boring on purpose

Repo, CI/CD, observability, auth, deploy. The dull plumbing that makes weeks four through forty fast.

03 / Build & ship

Two-week cadence

Working software in your hands at the end of every sprint. Never a roadmap deck in lieu of code.

04 / Operate

Or hand off cleanly

We run it with on-call and SLOs — or transfer ownership to your team with full runbooks and engineer pairing.

Six rules
we don’t break.

The shape of our practice, written down. If a project would make us violate one of these, we don’t take it — that’s how a small studio stays small and sharp.

01

On-call is part of the work.

The team that builds it also operates it. Reliability isn’t a function someone else cares about — it’s in the spec.

02

Boring tech, when it earns it.

Novel where it unlocks a real 10×. Boring everywhere else. Bored engineers ship more software than excited ones.

03

We write what we deploy.

No throwing it over the wall. Same hands that compile the code test it, deploy it and get paged for it.

04

Senior by default.

No bench, no farm-out, no junior we’re training on your bill. The people who scope the work ship the work.

05

Two-week demos, always.

Working software at the end of every sprint, in your hands. Never a roadmap deck in lieu of code.

06

Off-ramp without lock-in.

30-day rolling termination. IP fully yours. Runbooks written for your team, not held hostage by ours.

that needs to be real?
