Your idea.
Engineered.
We build AI-powered products for founders who need an engineer, not an agency.
From $1,500 · Full code ownership · Fixed milestones
This is not
an agency.
You get one engineer who owns the full stack — from design to deployment. Fixed milestones, direct communication, no hand-offs. The kind of velocity you only get when one person is accountable for everything.
Ships in weeks, not months
From scoping call to deployed product in 2–6 weeks. No discovery phase theatrics. No sprint planning ceremonies. Just building.
Your code. Full stop.
You own every line from day one. No proprietary tooling, no licensing, no lock-in. Hand it to anyone at any time — or never think about it again.
Real AI, not chatbots
LLM integrations architected into the product — not bolted on as a feature. Custom prompting, eval pipelines, measurable output.
Fixed milestones, zero surprises
Quoted before work starts. Milestone payments, not hourly billing. If scope changes, we re-quote before touching code. That's the whole contract.
Three steps.
No overhead.
Built for founders who want to move — not spend three weeks in kickoff meetings before a line of code is written.
01
Discovery Call
We scope the build together in 30–60 minutes. Milestones, timeline, and price are agreed before any work begins. No retainer required to start the conversation.
~30 Min Scope Call02
Build
Regular check-ins, demos, and progress updates. You stay in the loop without micromanaging. Each milestone has a clear deliverable before the next payment triggers.
Weekly Updates03
Ship & Hand Over
Deployed, documented, and handed to you cleanly. Optional retainer for ongoing changes. Or walk away with full ownership — no lock-in, ever.
You Own EverythingWhat we've built.

Built for founders
who think in products.
01
Pre-seed Founders
You have the idea, the conviction, and the funding to start. You need someone who can turn a Figma file into a live product — fast.
02
Post-raise Startups
Just closed a round and need to ship before the next one. You need execution, not another agency kickoff deck.
03
AI-First Products
Building something where AI is the product, not a feature. You need an engineer who understands LLMs beyond the API docs.

Jack Moffatt
Founder & Lead Engineer
I started Trelo because I kept seeing founders lose momentum waiting on developers who didn't understand the product.
I build fast, I communicate clearly, and I stay until it ships. That's the whole thing.
