Solutions architect
The right stack and structure for your problem, chosen, not templated.
About the studio
One builder with the range of a whole product team.
Lab Twelve is a founder-built, AI-native dev studio. Most software needs a solutions architect, a product manager, a product and web designer, and a senior engineer. Here that is one person, a 100x AI-native engineer with real product judgment and business acumen, who makes the right calls, builds for web, mobile, or native, makes it look great, and ships fast, from a short conversation to an app live in production, for a price you see before you pay.
What you get
Four specialists. One fixed price.
A real build needs a solutions architect, a product manager, a designer, and a senior engineer. Lab Twelve is all of them in one, AI-native and founder-led, with the product judgment and business acumen to make the right calls, so you get the right architecture, a product that is genuinely well designed, and a fast deploy to production, web or mobile, without hiring a team or paying an agency to run one.
Product manager
The hard product calls — what to build, what to cut, and when to challenge the brief before it costs you.
Product & web designer
Premium, modern UI built with real craft, never vibe-coded slop.
100x AI-native engineer
Built, tested, and shipped fast. Web, mobile, native, the right tool for the job.
How the work gets done
Understand. Architect. Build & test. Deploy.
Every build runs the same four phases, in order. No skipped steps, no prototype handed off as a finished product.
- 01
Understand
We pin down the real job-to-be-done before a line of code.
- 02
Architect
The best architecture for the solution, not whatever's trendy.
- 03
Build & test
Implemented properly and tested, production-grade, not a prototype.
- 04
Deploy
Shipped to production with handoff docs and the source code.

Who you're hiring
A studio that tells you what you need — then builds it.
Too many founders get burned — agencies that quote low and bill high, freelancers who disappear, platforms that hold your code hostage. Lab Twelve is the opposite: fixed price before you pay, source code yours at handoff, and one team doing the work start to finish.
We'll tell you when your approach needs adjusting before we build it. We say no to projects we can't deliver well. The scope lock and fixed price aren't just features — they're what an honest engagement looks like.
Wide experience across startups, B2B SaaS, and consumer products, with real business judgment built from working closely with founders at every stage. If you want a team that'll be straight with you and work hard for your success, that's who you're hiring.
