App studio, prototype consultancy, and AI launch support.
We help founders validate ideas, polish promising apps, and learn the workflows behind modern web, mobile, and App Store launches.
Choose the right level of help.
The starter pack is one lane, not the whole studio. We also shape prototypes, advise founders, and take on selective app studio work.
App Studio
For owned products and selective partner builds where taste, product direction, and launch polish matter.
- Studio-led product shaping
- Interface polish and launch readiness
- Selective builds when the fit is right
Prototype Consultancy
For founders with an idea, rough prototype, or AI-built app who need senior direction before spending serious money.
- Prototype audits and next-step plans
- Pair-building and implementation unblockers
- Fast feedback on viability, scope, and risks
- Architecture audit + handoff packet for the next dev shop
AI Web Starter Pack
For builders who want the playbooks, checklists, AI workflows, and App Store guidance to keep moving independently.
- App Store Launch Packet
- AI-tool workflow database
- One-hour launch consult
Open to where these go next.
Most apps in the portfolio have been designed and built solely by Saint Marlo Labs. The studio doesn't have the bandwidth to take each one to its ceiling — but the right team could.
Two doors are open. If you'd like to acquire one of these projects outright and run with it, Saint Marlo Labs is open to the conversation. And if one sparks an idea, the studio can build a different version — or a spin-off for your own purposes.
Everything in the portfolio is open to inquiry, with no list price set up front; each one is a conversation.
Most agencies hand you a prototype. We hand you the keys.
We build working prototypes fast, then hand over the detailed packet most agencies never share — so you or any dev shop can take it to production without guessing.
- Backend architecture overviewData model, service boundaries, hosting recommendations, and the diagrams another team needs to ramp in a day.
- Repo & codebase walkthroughFolder map, key modules, run instructions, branch strategy, and the conventions we used so nothing is a mystery.
- Language + features inventoryStack, libraries, what's fully built vs. stubbed, and the rationale behind each choice.
- API & backend checklistEvery external API, env var, webhook, and integration you'll need to wire up — in the order that won't break things.
- Seamless handoff docAll of it packaged so another dev shop can pick it up on day one without a discovery phase.
You see the whole architecture, not a black box. Most agencies guard this — we hand it over.
The packet is written for any competent dev team, not just us. You're never trapped.
A prioritized checklist of what's left to wire up, so the path from prototype to launch is concrete.
Preview of the handoff dashboard you'll receive. Click any row to mark what you already have — we'll document the rest.
"There was no shortage of ideas — only a shortage of affordable ways to test them. This is the shortcut our founder wished existed."
AI Web Starter Pack + App Store Launch Packet.
Built for people with a prototype, idea, or AI-generated app. The hard part isn't any single step — it's that the steps live across a dozen sites, in no obvious order. We've run that gauntlet enough times to compress it into a single play-by-play, plus an hour of senior guidance so you're never stuck.
Launch, growth, analytics, push, support, legal — every rabbit hole already mapped. You inherit the finished sequence and spend the saved months on your product.
The work most founders pay $25k–$250k for — store setup, build pipelines, analytics wiring, push, legal scaffolding — is in the packet.
Every step, in the order that won't break things, compressed into one sequence you just follow.
We explain the mindset, checkpoints, and tradeoffs so you understand why the next step matters — not just what button to press.
Traditional developer engagements can leave you waiting for every small change. Our goal is to help you spot risks, ask better questions, and keep building.
We can help shape prototypes and launch paths, but we are not selling a blank-check full-app build. The product is the playbook and coaching that lets you take the training wheels off.

A few ways to work together.
Some founders want precise execution. Others want a senior creative partner who can spot extra opportunities while the prototype takes shape. We scope either lane clearly before the work starts.
We can build to your exact specifications, stay tightly inside the requested scope, and do only what you ask us to do.
If you are open to it, we can add a creative package where you give us room to suggest and implement additive features, flows, or design details you may not have thought of yet.
Polished products and partner builds, when the fit is right.
The studio designs and ships its own portfolio and selective partner products — studio taste paired with prototype discipline, so deeper builds happen after the idea earns the investment.
