Forward deployed engineering

An engineer inside your business, building against your real systems.

We work inside your team instead of from a ticket queue: learn how the work really gets done, build the piece that is missing, connect it to the tools you already run, and stay until your people use it.

What it is

Software that works in a demo often fails in a real business.

Real data is messier, the real workflow has steps nobody wrote down, and the tools in use were never meant to connect. So the engineer goes to the work.

Palantir named the role. AI companies, Anthropic and OpenAI among them, now put engineers inside customer teams the same way. We do it for small and mid-sized businesses.

The systems you already run, connected by the piece that was missing.

How an engagement runs

Five phases, and you see working software in the fourth.

  1. Embed

    We sit with the people doing the work, on their calls and in their spreadsheets, and watch how the day actually goes.

  2. Map

    Every system, every hand-off, and the steps that eat the most time. Written down so everyone agrees on it.

  3. Build

    The smallest thing that removes the worst step, built inside the tools you already run, with your real data.

  4. Ship

    In front of real users early, not after months of planning. We watch it get used and fix what gets in the way.

  5. Hand over

    Code, accounts and documentation in your name. We keep running it if you want, or your team takes it from there.

Where we have done it

MastroCC was built this way.

Mastro Management’s team sells to property managers by phone. We built inside that team: recording and transcribing calls in the browser, sorting each call by outcome, scoring the lead queue, and sending a daily briefing to Slack.

Its callers have used it since September 2026. Mastro Meet and Mastro world came out of the same work.

A good fit

If one of these sounds like your week, we should talk.

  • 01

    Work done by hand every day

    Logging calls, chasing follow-ups, copying data between tools, writing the same report every evening.

  • 02

    Tools that do not talk to each other

    A phone system, an inbox, a CRM and three spreadsheets, held together by someone remembering things.

  • 03

    A judgment call in the middle

    Sorting, triaging or deciding something a person does now. That is where a model earns its place; the rules around it stay in plain code.

Every engagement starts with a call and a written scope. The code, the accounts and the data stay in your name from the first day.

Tell us about the busiest part of your team’s day.

Fifteen minutes is usually enough to know whether there is something worth building.
