Workflow automation
End-to-end flows that move data, trigger actions, and close the loop across your tools — with AI deciding the judgment calls a script can’t.
Spec. Build. Ship.
AI automations and custom software for businesses that can’t afford to get it wrong. Senior US team. Shipped in days.
AI automations
Put AI to work on the boring parts.
We build AI automations and AI-powered workflows that take real work off your team — document handling, customer ops, internal lookups, sales follow-up, compliance review. Production-grade, on your stack, with humans in the loop where it matters.
AI agents & copilots
Internal copilots that know your data, agents that handle repeatable customer or ops requests, and RAG systems built on your knowledge base.
AI-powered ops
Document extraction, intake triage, ticket routing, contract review, intelligent search — the deterministic glue that turns LLMs into useful product.
Why us
Built different.
Senior-only team
No junior bench, no account-manager layer. The people who scope the work also write the code — US-led, distributed senior engineers behind every line.
AI-augmented delivery
We embed AI into every stage of development — from spec to test — so projects that used to take quarters reach working software in days and production in weeks.
Regulated-domain expertise
Deep experience in Fintech, Insurtech, and Legaltech. We know your compliance, audit, and integration constraints before you explain them.
Industries
We know your world.
Three regulated industries where we’ve shipped both AI automations and custom platforms. Same senior team, same Spec/Build/Ship cadence.
Fintech
Lending systems, payment infrastructure, compliance tooling, core banking — including custom loan origination systems built for non-standard underwriting workflows at scale.
Insurtech
Policy management platforms, B2B CRM for broker and carrier networks, and carrier integrations that streamline the full distribution chain.
Legaltech
Case management platforms, document automation, and matter tracking — scaling to thousands of active matters across departments.
How we work
One. Two. Three.
-
Discovery
A two-week paid spec sprint. We produce a written spec, an architecture diagram, and a milestone plan you own outright — whether you build with us or not.
-
Build
Two-week sprints, weekly demos, your team in the loop. AI-augmented but human-reviewed. Working software in days, not quarters.
-
Ship
Production handoff with documentation, monitoring, and 90 days of post-launch support. Code, infrastructure, and decisions stay with you.
Case studies
Work that speaks.
Fintech
Loan Origination System
Problem. Niche US lenders needed a tailored origination flow that standard platforms couldn’t support.
Outcome. End-to-end custom LOS built to handle non-standard underwriting workflows at scale.

Legaltech
Legal Case Management Platform
Problem. One of Eastern Europe’s largest banks needed a unified system to manage complex legal matters.
Outcome. Comprehensive case management platform handling thousands of active matters across departments.

Insurtech
B2B Customer Relationship System
Problem. A New York-based insurer lacked tooling to manage its broker and carrier network effectively.
Outcome. Purpose-built B2B CRM streamlining relationships across the full distribution chain.

Software is a craft. We treat it that way.
We started onetwothreework because we kept seeing the same thing — smart companies stuck with off-the-shelf software that almost fit. A lender bending its underwriting rules around a vendor product. An insurer paying a seven-figure license for a CRM that didn’t understand brokers. A law firm running its biggest matters out of spreadsheets.
So we built a small senior team to do the thing those companies actually needed: write the software, ship it quickly, and stand behind it. No layers of account managers. No junior bench. The people who scope the work also write the code, and AI handles the parts that used to soak up weeks.
We’re a Los Angeles-based boutique with senior engineers across two continents. We pick projects where the problem is real and the constraints are interesting — regulated industries, complex domains, and teams who’d rather get it right than get a demo.

FAQ
Common questions.
How do you structure engagements?
Most engagements start with a paid two-week discovery sprint. After that, we work in two-week sprints on a time-and-materials basis with monthly burn-rate caps, or on milestone-based fixed scope when the work is well-defined. We do not do uncapped open-ended T&M.
What is the minimum project size?
Our discovery sprint stands alone — you walk away with a spec and architecture even if you don’t build with us. Beyond that, our typical engagement is at least a few months of senior engineering. If your problem is smaller than that, we’ll tell you and recommend someone who fits.
Who owns the code?
You do. Code, infrastructure-as-code, documentation, and decisions transfer to you at every milestone. We don’t use proprietary frameworks or hold deliverables hostage. If you stop the engagement, you keep everything we’ve produced.
Where are your engineers based?
Headquarters and senior engineering leadership are in Los Angeles. We have additional senior engineers distributed across two continents to give clients near-24-hour delivery cycles. Every engagement has a US-based point of contact accountable for outcomes.
Do you sign NDAs, DPAs, and BAAs?
Yes. NDAs as standard before any sensitive conversation. DPAs and BAAs as needed for regulated engagements in Fintech, Insurtech, and Legaltech. Send your template and we’ll review within a few business days.
