How we work
FIVE STAGES05 / 07
Stage 011–2 weeks
Discovery
We work out where you actually are, which is rarely where the brief says. Stakeholder interviews, a read through the existing codebase, and an honest look at the analytics and the incident history.
You receive
Findings report and a scope we both believe
Stage 022–3 weeks
Design & Architecture
The whole system on one page before any of it gets built: user flows, the states that matter, service boundaries, and the risks we can name up front. This is the cheapest point to change your mind.
You receive
Designs, technical architecture and a risk register
Stage 038–16 weeks typical
Build
Two-week sprints, each ending in something you can click on a staging environment. No status decks — you see the real thing running against real data, or the sprint did not finish.
You receive
Working software every two weeks
Stage 041–2 weeks
Launch
Staged rollout behind feature flags, load testing before you need it, and monitoring configured before go-live rather than after the first incident.
You receive
Production launch, dashboards and alerting
Stage 05Ongoing
Support & Handover
Documentation written for the engineer who inherits this, training sessions with your team, and an SLA if you want one. If your team cannot maintain it after we leave, we did not finish the job.
You receive
Documentation, training and optional SLA

Team
03 PEOPLE06 / 07
Product & Frontend
Renna Voss
Founder & Principal Engineer
Fifteen years building software for people who did not choose it. Previously led engineering at a logistics platform through 4x headcount. Founded Intervia in 2019.
Platform & APIs
Idris Kalu
Principal Engineer
Writes the unglamorous code that keeps working. Cares more about the 95th percentile than the demo, and will argue about database indexes for longer than is polite.
Discovery & UX Research
Ma Sun-ho
Head of Research
Trained as an ethnographer, now applies it to clinical and industrial software. Has sat through more shift handovers than anyone should have to.

Read the case study“They spent two weeks telling us our brief was wrong, and they were right. The thing we ended up building is the thing we needed.”

Tell us what you need built
Whether it is a new product, a system that has outgrown its first build, or a migration nobody wants to start — send us the shape of the problem and we will tell you honestly whether we are the right people for it.
