Custom software development company
Custom Software Development Company
We design and build custom software that runs in production — platforms, AI products, and the systems a business runs on. Built end to end by a senior team that owns delivery.
Senior engineers who own architecture to delivery
AI at the core, not bolted on
You own everything — code, data, roadmap
What we build
Software a business actually runs on
Custom web & mobile applications
Products people use every day — not a prototype that stops at the demo.
SaaS & enterprise platforms
Multi-user systems with the auth, roles, and workflows the operation needs.
AI products & automation
AI in the product and in how we build it, reviewed by a principal engineer.
Operational & internal software
The tools a team uses to run the business, not a generic off-the-shelf fit.
Data systems & integrations
Pipelines, APIs, and the connections between systems you already rely on.
Legacy modernization
Make what you have reliable enough to build on, without a forced rewrite.
How AI fits our work
AI changed what building software is. We build that way.
Our senior engineers direct AI that writes code underneath them — and they review and own every line that ships. AI accelerates the work; it never decides what's right.
A real starting point on day one
AI turns your vision into a structured SRS, wireframes, and a first working product direction in hours, not weeks — so you're reacting to something real, not a blank page.
The repetitive work, automated
Boilerplate, tests, and documentation are AI-generated and engineer-reviewed — shorter cycles and fewer early bugs.
A principal engineer owns the result
Every change is reviewed in context before it ships. You're never handed raw AI output.
You own what it produces
The SRS, the designs, the code, the docs — all yours.
The result: delivery timelines cut by roughly 40–50%, and fewer bugs in early releases — without cutting corners.
EV charging · US
ChargeOnSite — a live charging platform for large property networks
Bookings, payments, access control, and live monitoring, with OCPP so multiple charger vendors work without hardware lock-in.
Energy data · US
Peak ETL — oil and gas data unified across all 50 states
Pipelines that ingest well, production, land, and regulatory data, and add new states without rebuilding the system.
AI product
Jeter — from product vision to a live, patent-pending AI product
A compatibility engine built around values, personality, and behavior, shipped with a senior team and AI in the loop.
Operational software
Pattern50 — studio operations brought into one live platform
Files, contracts, billing, resource hours, and client status in one system a US studio actually runs on.
How we work with you
Build, fix, or scale — one senior team
Build
New production software end to end, from first architecture to launch.
Fix & Stabilize
Make what's slow, breaking, or fragile reliable enough to build on again.
Scale & Maintain
Grow and run the system with a senior team that stays on it.
How we start
Start small. Own everything. No lock-in.
Start with a technical review
A senior engineer, often our CTO, finds the real constraint and what's worth building, fixing, or leaving alone.
We scope the piece, not a rebuild
One clear outcome. Your stack, vendors, and team stay.
You own what gets built
The code, the data, the roadmap. No lock-in.
Industries
Deepest in energy, mobility, and data — and custom software for operations-heavy businesses of every kind. The common thread is operational complexity, not the industry label.
Pricing
Priced to the work
Scope, team, and terms in writing before anything starts. You pay for completed work.
Scoped engagement
In writing first
We define the piece, the team, and the terms before engineering starts. Milestone-based — you pay for completed work.
Best for: A defined outcome, not an open-ended retainer
