Our process
From written scope to running product.
// 01A written cut list before any codeScope
We write down the user, the one flow that has to work, and everything we are cutting to hit the date. You approve that list, or we argue about it. Nothing gets built off a conversation nobody wrote down.
// 02A two-minute Loom every 48 hoursBuild
Each one shows what changed, what is next and what decision we need from you. You never have to ask for a status update, and nothing gets built for a week in a direction you did not agree to.
// 03Deployed to your accounts, keys handed overLaunch
We deploy, test and hand over the code, the infrastructure and every account, so no developer can ever hold your product hostage. Two weeks of fixes and a 30-day scaling programme are included.
// 04The engineer who built it stays on itRun
When the product needs work every week but not a full-time salary, Run is $2,999 a month for 40 hours from the person who shipped it. Pause or stop any month.
You talk to Prince, who writes the code. Small and senior on purpose — the person who scopes your build is the person who ships it.

Introducing The Lab
The products we build when we are the client. We choose the problem, fund the build, launch it and live with every decision after release — then bring those lessons back to every client product.
Built for people with a date, a broken path, or a quote they cannot swallow.
Who this is for
Serious buyers
- Funded or revenue-backed founders who have a date
- A product that takes payments, or is about to, and broke past the demo
- Agencies that sold a build they cannot staff
- Ops teams still running the business in WhatsApp and spreadsheets
- Travel, events and D2C teams whose enquiries wait hours for a reply
- A previous freelancer or agency that went quiet
Who we turn away
We will say no
- Idea-only founders who will not cut scope or validate
- A whole company for a bargain-shop budget
- SOC 2, HIPAA, or a 24/7 desk as a hard requirement
- Open discovery on a fixed price
- Buyers who want cheap developers, not a written scope
Signs you need this
Trigger events
- A customer paid and the app has no order
- Hiring the first engineer is taking a quarter
- The last shop re-quoted at week three
- Lovable, Bolt, v0 or Cursor got you to 80%
- You won the project and do not have the people
- Your team repeats the same task by hand every day
Questions a serious buyer asks before the call
What is an AI-native product studio?
A studio that builds with AI in the workflow and puts AI agents in the product. We use AI tools to write, test and review code faster, and a senior engineer checks every change before it ships. What it is not: an app generated from one prompt. We run App Rescue because those break in production.
Why not hire internally?
A first engineer is a search, a salary and three to six months. A clearly scoped Production MVP is $3,999 and about 21 days when the cut list is agreed. After launch, Run is $2,999 a month for 40 hours from the person who shipped it — pause any month.
Why work with a studio in India?
India-origin. Worldwide production. The person who writes the scope merges the code. You own GitHub, cloud and Stripe from day one. That is not a leased bench and not a junior bait-switch. If timezone is the objection: a two-minute Loom every 48 hours, async-first.
How do I know you will deliver?
Written cut list before code. Something clickable on day one. Loom every 48 hours, bad news first. Four named products you can look up. If we are full we say so and give you a date.
Who owns the code?
You do, from day one — not on final payment. Repository, infrastructure and every account sit in your name. If we stopped tomorrow you would still hold them, documented.
Can you fix another agency’s code?
That is App Rescue. Send the live URL. You do not need the old repo. Written keep / fix / rebuild in 48 hours, free, yours to keep.
What happens after launch?
Two weeks of fixes, a 30-day scaling programme and a 90-day roadmap are included. Then you choose: clean handover, or Run at $2,999 / 40 hours.
What kind of AI agents can you build?
Any workflow with clear inputs, rules you can write down and a clear hand-off: support, operations, finance, documents, hiring, sales, or a copilot inside your own software. They connect to your existing tools through their APIs, act only within the permissions you set, and log every action. If the job needs judgement nobody can write down, we tell you it is not ready for an agent.
Do agents replace my team?
No. They take the first pass and the repeated steps; your people take the decisions that need judgement. Count how many times last week someone did the same task by hand. That is where an agent starts.
