SEATECHONE
PRODUCT STUDIO · SEATTLE

We Build B2B SaaS Products. End to End.

From database schema to payment integration to AI pipeline — SEATECHONE ships production-grade software for founders and operators who need a technical partner, not another consultant.

The studio

We operate the software we build.

Most studios only deliver. We run our own products in production — so we build yours like operators, not contractors.

Proof, not promises

Two products. Live in production.

GuardBench

AI Safety

Benchmark, compare, and gate AI safety guards in CI — so a regression never ships. Open-source, EU AI Act–ready.

SEAREI

PropTech

Move the threshold and the safety gate decides — pass or block — against your policy. It's the discipline behind GuardBench.

What this means for you

Built to last past launch.

The full stack, owned by one team.

Schema, API, frontend, payments, and AI pipeline — designed together, not stitched from contractors. One team accountable end to end.

Compliance designed in, not bolted on.

Audit trails, role-gated workflows, and EU AI Act–ready documentation from day one — because that's how our own products are built.

Handed off clean. Yours to run.

Tested at 80%+ coverage, fully documented, all IP transferred. Any engineer is productive in the codebase within a day.

How we work

Three phases. Fixed scope.

A written spec and a clear budget before any code. No open-ended retainers.

Phase 01

Architecture

Data model, service boundaries, and a written single source of truth.

~1–2 weeks
Phase 02

Build

Full-stack delivery — auth, payments, core workflows — tested and deployed.

~6–10 weeks
Phase 03

Production

Compliance, AI, hardening, and a clean handoff with everything you need.

~2–4 weeks

What is SEATECHONE?
A Seattle product studio. We ship our own software — SEAREI and GuardBench — and build production-grade B2B SaaS for founders and operators.
Do you build for clients, or just your own products?
Both — and a small number of client engagements at a time, held to the same standard as our own products. You own all IP on final payment.
Can you help with EU AI Act compliance?
Yes. GuardBench produces audit-ready evaluation documentation mapped to the EU AI Act and NIST AI RMF. Full enforcement for high-risk systems begins August 2026.
How is an engagement priced?
Fixed-scope phases with written specs — no hourly billing. Budgets typically run $15,000–$45,000 per phase. A shippable v1 is usually 8–12 weeks.
