What we build

Four ways to put a team to work.

Whether you need a full product built or a few extra engineers on your team, we fit in at whatever level makes sense — and scale up or down as you go.

How we work

No black boxes. You see it happen.

A straightforward path from first call to launch — with visible progress every single week.

01

Discovery call

We learn your goals, scope, and constraints — and tell you honestly if we're the right fit.

02

Proposal & plan

A clear scope, timeline, and fixed quote before any code is written. No surprises later.

03

Build in sprints

Weekly demos and a live board. You see real progress every week, not just at the end.

04

Launch & support

We ship it, watch it in production, and stick around to iterate as you grow.

Why Onosoo

Built to be the partner you don't have to manage.

/ Built to last

Clean, documented, tested code — so what we ship is easy to maintain and hand to your next developer.

/ Timezone-friendly

We flex our hours to overlap with your team — so you get same-day answers, not next-day.

/ Transparent pricing

Fixed quotes for projects, clear monthly rates for teams. You always know exactly what you're paying for.

/ Clear communication

Slack access, weekly demos, and a project lead who actually replies. Fluent English, every conversation.

Our stack

Modern tools, chosen to last.

We pick tools that are easy to maintain and easy to find developers for — so your product is easy to grow and easy to hand over.

A sense of what we build.

These are illustrative project types based on what we build — swap them for real case studies as projects land. Want references or examples now? just ask.

You own everything we build.
Every line of code, transferred to you.

No lock-in, no hostage repositories, no "our platform." When the work is done, it's yours — source, assets, and accounts included.

Common questions

Before you reach out.

The questions we hear most from teams evaluating an outsourcing partner for the first time.

Who owns the code and IP after the project is delivered?+

You do — entirely. Everything we create — the code, the accounts, the passwords — gets handed over to you. There's no shared platform, no licensing fee, and no dependency on us to keep running what we built.

Do you sign NDAs?+

Yes. We'll sign your NDA before any detailed discussion of your product, or provide our own if you'd prefer to start there. This is standard on every discovery call.

What happens if I'm not happy with a delivery?+

You'll see the work in progress every week, so surprises at the end shouldn't happen — but if something's off, tell us and we'll revise it against the agreed scope at no extra cost. If it's a bigger disagreement, we'll work it out before moving to the next sprint.

What's your revision policy?+

Every sprint ends with a demo and a round of feedback, so small revisions are already part of the process. Anything beyond what we originally agreed gets quoted separately, upfront, before we start on it.

How does timezone overlap work?+

We shift our working hours to overlap with yours for part of each day — for calls, questions, and working together live — and send regular updates through Slack the rest of the time.

What happens after launch?+

We stay on to watch how it performs after launch, fix anything that comes up, and are available to keep improving it — either on retainer or as new fixed-scope phases, whichever fits what you need next.

Do I need a technical co-founder to work with you?+

No. Many of the founders we work with are non-technical. We translate your goals into a scoped plan, explain tradeoffs in plain language, and make sure you understand what's being built and why at every step.

What's the minimum engagement size?+

It depends on the shape of the work — a scoped MVP and a long-term dedicated team have different minimums. Tell us what you're building on a discovery call and we'll give you a straight answer before any commitment.
