Fewer
surprises. Longer partnerships.
+
One codebase, two stores
Shared logic written once, native where it matters, so iOS and Android stay in step release after release.
+
Every sprint ends installable
No demo-only branches. Each fortnight you get a signed build, a plain-language changelog and a short walkthrough.

Handover is in the contract
Architecture notes, runbooks and a two-week pairing window are written in from the start, not bolted on at the end.
Working together
Your engineers are good. Ours make them faster.
We are not here to replace an in-house team. We join your board, your standups and your repo, take the work that has been sitting in the backlog since spring, and leave your people free to hold the roadmap.
- A named squad — not a rotating pool of contractors
- Four hours of overlap with your timezone, written into the agreement
- Code review both ways , so the knowledge does not leave when we do

The build train
Five stages. Nothing skipped, nothing padded.
Each stage has an exit condition you sign off before we spend a rupee or a dollar on the next one. Click through to see what you get at the end of each.
Pull the idea apart before anyone writes code
We map the flows, name the risks, cut what will not earn its build cost and put a real number on the rest. You leave with a plan you could hand to any studio.
You end the stage with
- Technical discovery document
- Risk register with mitigations
- Costed, sequenced build plan
Five real users try to break it before we build it
Flows, a clickable prototype and moderated testing. Every state gets drawn — empty, loading, error, offline — so nothing gets invented during the build.
You end the stage with
- Clickable prototype of the core journey
- Component library exported as tokens
- Recorded user-testing sessions
Fortnightly sprints that end with something installable
The squad works in your repo, on your board. Every second Thursday you get a signed build, a plain-language changelog and a short walkthrough video.
You end the stage with
- Signed build every second Thursday
- Changelog written for non-engineers
- Burn-up chart you can read alone
Submission, staged rollout and a rehearsed rollback
Store listings, screenshots, privacy declarations and review responses. The rollout starts at 5% with automatic halt thresholds wired to your alerting.
You end the stage with
- Store listings and assets submitted
- Dashboards and alerting handed over
- Rollback rehearsed before day one
Retention work, or a clean exit — your call
Two weeks of pairing with whoever inherits the app, then either a reduced squad for the next release, a light support retainer, or a documented goodbye.
You end the stage with
- Runbooks and architecture notes
- Two weeks of pairing handover
- Performance budgets set for the next team

In their words
What clients say after handover
We ask for these six months after the final invoice, when the honeymoon is over and the app is somebody else's responsibility.
The handover pack was the part that surprised me. Our two in-house engineers picked up the codebase in a week and have shipped four releases since without calling anyone.
Tobias Lindqvist
CTO, Nordbyte Logistics
They cut a third of our feature list in the scoping week and were right about all of it. That one conversation saved more money than the whole engagement cost.
Amara Sethi
VP Product, Larkfield
Our compliance team is famously difficult. Nimblestack turned up to the review with the audit trail already written. First submission, no findings.
Dr. Helena Marsh
Clinical Director, Vesper Health
Every second Thursday there was a build on my phone. After eleven years of agency slides, that alone was worth the rate.
