Not case studies from a deck. These three we designed, built and still run — so you can judge the work before you commission any of your own.
SIM and subscriber management end to end: provisioning, plans, usage and billing in one console — with a field app that keeps working when the signal doesn't and syncs the moment it returns.
Properties, tenants, leases and payments for agencies that outgrew the spreadsheet. Renewals chase themselves, arrears surface on their own, and the owner statement is one click instead of one evening.
Every asset tagged, assigned, serviced and depreciated on schedule. Audit week becomes an audit afternoon: scan, confirm, sign off — the register was already right.
A product real users can log into. We cut scope honestly instead of padding an estimate, and it's running on a live URL in week one.
Internal software shaped around how your business actually runs — not how an off-the-shelf tool wishes it ran.
iOS and Android from one codebase, offline-first where the work happens away from a signal. MobiSIM is the proof.
Monitoring, patches and the unglamorous reliability work that keeps you off incident calls at midnight.
A call, no slides. We ask what breaks today, who it hurts, and what you'd do with the time it costs you.
A written plan with a price and a date. If we don't believe it can be done for that, we say so before you sign anything.
Two-week slices, a live URL from the first one, and a demo you can click every Friday. Change your mind early and it stays cheap.
Launch, then look after it — or hand your team the keys with documentation and a walkthrough. Both endings are fine with us.
“They shipped in ten weeks what our last vendor scoped for nine months — and still answer the phone after launch.”
“The asset register went from an argument to a fact. That alone paid for the project.”
from $12k
One price, one date, one deliverable. Right for an MVP or a well-understood system.
$6k / dev / mo
Senior engineers embedded with your team, monthly, 30 days' notice either way.
from $900 / mo
For software already live — ours, or somebody else's.
Budget and timeline aren’t a filter — they’re how we answer usefully instead of vaguely. An engineer reads this, not a mailbox.
Most of ours are. You describe the business; we write the scope in plain language and put something clickable in front of you early enough that changing your mind is still cheap.
You do, from the first commit. It lives in your repository and your cloud account — we're contributors, not landlords.
Yes, starting with a short paid audit: what's salvageable, what isn't, and the cost either way — before anybody commits to a rebuild.
We keep at least four hours of overlap with your working day, and everything else runs in writing so nobody waits overnight for an answer.
Either a care plan, or a clean handover with documentation and a walkthrough for your own team. We're happy with both.
Send the brief. Worst case you get a free second opinion from people who've shipped three products of their own.
