Xenion Labs designs and engineers web platforms, mobile apps and brand systems for startups and growing companies. Senior teams, fixed scope, and a codebase you own from the first commit.
Typically replies within one business day · No-obligation scoping call
Xenion Labs started in 2019 with a simple frustration: agencies that pitched with senior people and delivered with junior ones. We built the opposite. Thirty-eight specialists, no account managers between you and the people doing the work, and a bias toward shipping something real in the first fortnight.
We work with founders and product leaders across fintech, healthtech, logistics and SaaS — usually somewhere between a first prototype and a Series B, where the decisions you make now are the ones you live with for years.
A paid discovery phase produces a written scope and a fixed price. No estimate ranges that double halfway through.
Not a status update — a deployed build on a staging URL that you can click through and share.
If your project needs a specialism we don't have, we'll tell you and point you somewhere better.
Curious what a project with us looks like week by week? See the process.
Four disciplines, one team. Most projects use two or three of them together, which is the point — strategy, design and engineering decisions are cheaper to make in the same room.
Four phases, weekly reviews, and a deployable build every two weeks. You always know what we're working on and what it costs.
We start with your users and your constraints — interviews, analytics, a technical audit — and come back with a written point of view on what to build and what to skip.
Flows, wireframes and high-fidelity screens, reviewed with you every week. You see the real thing early enough that changing it is still cheap.
Two-week sprints with a working deploy at the end of each one. Code review, automated tests and a staging URL you can share from day one.
Launch, then measure. We tune performance, watch the funnel, and either hand the codebase to your team or keep shipping alongside them.
A sample of recent engagements. Every figure below came from the client's own analytics after launch, not from our estimate of what we might achieve.
An elite digital platform connecting top-rated, award-winning attorneys across the United States with clients seeking specialized legal representation.
Every project has a full write-up — read how they were built.
Four commitments we make on every engagement. They are in the contract, not just on the website.
The people in your kickoff call are the people writing the code. We don't staff projects with juniors behind a senior name on the pitch deck.
You get a written scope and a fixed number before we start. If we underestimate, that's our problem to absorb, not a change order.
Code, designs, infrastructure and accounts are yours from day one, in your repositories and your cloud account. No lock-in, no hostage situations.
Every project ships with tests, documentation and a walkthrough. The measure of good work is that you don't need us afterwards.
They pushed back on half of our original scope, and they were right about all of it. We launched two months earlier than planned with a product people actually use.
The handover was the best I've seen. Our engineers were shipping features in the codebase within a week, without a single call back to Xenion.
Xenion treated our brand like it mattered before we had the revenue to justify it. Two funding rounds later, we still haven't needed to redesign.
What we've learned shipping products — written for the people making the decisions, not for a keyword.
Every founder wants a fixed price for their software project. Every honest studio knows they can't give one without a paid discovery phase first. Here's what that phase actually contains, and why it's the shortest path to a real number.
Most performance advice optimises the metric instead of the experience. Here is the short list of changes that reliably improve both, in the order we apply them.
The failure mode is never building too little. It is building four half-finished things instead of one that works. A practical method for cutting scope without cutting the product.
If yours isn't here, email us — we answer scoping questions before there's a contract in sight.
Tell us what you're building and what's in the way. You'll get a straight answer on scope, timeline and cost — usually within one business day.
