Build service
We write the code. You own the code.
Custom web applications, mobile apps, internal tools, and AI agents. Built on the same Next.js and Go foundation that runs our Blueprints. Two to four weeks from discovery to production.
What we build
Production systems, not demos.
Custom web apps
Next.js 15 with Supabase auth and RLS. Multi tenant by default. Built to survive ten years, not one founder.
AI voice agents
Vapi, Retell, or custom infra. Ship a phone agent your patients actually call. HIPAA aligned when PHI touches the call.
React Native mobile
iOS and Android from one codebase. App Store submission, push notifications, offline sync.
Internal tools
Admin dashboards and ops tools nobody wants to build but everybody needs. Forms, queues, approvals, audit trails.
Integrations
Epic, Cerner, Allscripts for healthcare. QuickBooks, Stripe, Slack for SMB. Custom adapters where no off the shelf one exists.
Data pipelines
ETL, reverse ETL, analytics. Postgres, DuckDB, dbt. When a report breaks we fix the root cause, not the symptom.
How we work
The folder is the contract.
Every build follows the same five stages. Click a folder to see inputs, process, and deliverables.
“The folder is the contract.
The Friday demo is the proof.
The retainer is the relationship.”
00-discovery
What's broken. What you need.
inputs.md
- · 30 minute call or written description of the problem
- · Current process (however messy: screenshots, voice notes, spreadsheets)
- · Any existing software or integrations we need to connect to
process.md
- · We listen without a pitch deck
- · Map every manual step in the process
- · Identify what's automatable vs. what needs judgment
- · Check whether a Blueprint or Pack already solves it
- · Give you a straight answer: yes we can help, no we can't, or here's what we'd need
outputs.md
- · Written process map (yours to keep)
- · Honest assessment: build vs. buy vs. don't bother
- · Scope and budget range for the next stage
your review moment
You decide whether to proceed. No pressure, no follow up sequence.
When NOT to use this service
A custom build isn't always the right fit.
You need it running this week.
A custom build takes 2 to 4 weeks minimum. If you need something faster, a Blueprint pack is the right starting point. It's already built.
You don't have a defined spec.
We build against a written spec. If you have a general idea but no specific requirements, start with the AI Audit first. That's where specs come from.
You want to try before committing to a full build.
If you're not sure the system will solve the problem, start with a Discovery Audit at $2,500. You'll get a written spec and a clear recommendation before any code is written.
