Testimonials

What clients say

Early-stage teams care about three things: on-time delivery, price, and who fixes things after launch

★★★★★

We had nothing but a rough idea. Three weeks later we were demoing a working MVP — customer Q&A and knowledge-base retrieval both live — in our funding pitch, for a fraction of what three overseas agencies quoted.

— AI product founder · Seed round

★★★★☆

Quality was never the issue — multi-turn dialogue and tool calling were rock solid. Working across time zones was rough for the first two weeks, until we fixed a daily overlap window. Sort that out on day one.

— AI SaaS startup · Hong Kong

★★★★★

Fixed pricing saved us the back-and-forth. I added scope twice — one more model, a voice pass — and both times they quoted first and waited for my OK. No hidden fees.

— AI SaaS team · Singapore

★★★★★

In one line: the all-in-one assistant they talked me out of building was the right call — the model simply could not carry it. I spent those two months on users instead.

— AI product team · Southeast Asia

★★★★☆

Speed and pricing were good. My one gripe: the docs were written for engineers, not for me — prompting and evals especially. They added an operator-facing version once I asked.

— AI data product · North America

★★★★★

We had a vague idea and a small budget. They didn't turn us down — they built a working demo first (photo capture + structured output) so we could raise, then started the real build after the round closed.

Why we stay pseudonymous: most core members still work at their current companies or are under non-compete and NDA periods, so we don't publish individual identities. Before signing we can arrange a live video due-diligence call, share redacted project write-ups and live product demos, and let you nominate a third party to review the code.

Call for Partners

Co-Build Partner Program

We bring the product direction, design and growth. You bring the engineering team. Nobody pays development fees upfront — we split whatever the product earns.

3 product seats in this first cohort Development fee $0 Net revenue 50 : 50 One-page agreement, signed before kickoff

We bring

Product & Growth

Product direction and requirements: market call, user research, written spec and prototypes — defined before a single line of code.
Design and brand: UI/UX, website and landing pages, sales collateral.
Growth and monetisation: launch traffic, channels, sales and pricing, plus user growth after launch.

You bring

Engineering

The build team: a stable 2–5 person crew (frontend, backend, DevOps), committed for at least 3 months.
Engineering: architecture, code, testing, release, and ongoing technical maintenance.
Delivery cadence: one progress sync per week, milestone demos you can actually click.

Nobody pays

No Cash Upfront

No membership, deposit or training fee from us — no fee under any name.
No upfront development cost from you: your engineering hours are your equity, paid back from revenue.
Servers, model APIs and other direct costs are covered by product revenue first, before the split.

How the money splits

Net revenue = product revenue − direct costs (servers, model APIs, distribution)

Us 50% · product & growthDev team 50% · engineering & delivery

Settled monthly, paid by the 10th of the following month; both sides can audit the numbers.

The ratio is negotiable based on actual effort — 40 : 60 when engineering carries more weight.

If one side exits, revenue share on the live product continues for 12 months, then settles.

We are not looking for another dev shop

We are looking for partners who can judge whether anyone will actually pay for this. Six hard requirements:

Shipped products, with links we can open. We only work with teams that have delivered — decks and resumes alone don't qualify.

You can read the market, not just take tickets. If you think our direction is wrong, you must be able to say exactly why and what to change. That is the whole point.

Full-stack ownership. You can take it from zero to live — architecture, code, deploy, monitoring — without us hiring anyone else.

Demo-able MVP in 4–8 weeks. Core loop first, polish later, with visible progress every single week.

You will sign a one-page agreement. It covers three things only: revenue split, IP ownership, exit terms. Code and brand belong to the project entity; exit is settled against proven contribution.

Fluent in English or Chinese. At least one sync per week, and both sides sign off on major decisions.

STEP 01

Apply

Two minutes: your team, your stack, what you have shipped.

STEP 02

Screening in 48h

We review your work and the fit. You hear back either way.

STEP 03

60-minute review

We walk you through the market, the user and the monetisation — you judge if it can be built.

STEP 04

Sign and build

One page signed, kickoff within 7 days, first demo in 4–8 weeks.

Application received

We'll get back to you within 48 hours. In a hurry? Message the founder directly.
