We build the software your business runs on.

Custom software for a specific job: a legacy rewrite, a new feature, an integration, or a ground-up build. We scope it with you, build it, and hand it over. Based on Long Island, working with businesses across the US.

What we build

A clear scope. A working result. Yours to keep.

  • Build something new

    A focused tool or a full product, scoped and delivered in working pieces.

  • Move an existing system forward

    A legacy rewrite, an integration, or the next feature in your own codebase.

  • Take a task off your plate

    An automation, a reporting tool, or a focused fix for a process that keeps slowing you down.

Every project starts with a written scope and an estimate, agreed before any build begins. The work is billed by the hour against it, and nothing outside the scope starts without your OK.

How a custom software project runs

Websites, too.

Web design for Long Island businesses that win on calls, bookings, and walk-ins. Built for phones and local search, then hosted and kept running by us.

How it works

  1. 01

    Talk it through

    You tell us what is slowing the business down.

  2. 02

    Agree the scope

    You get a written scope and an estimate before the build starts.

  3. 03

    Build in working pieces

    You try each piece as it lands, most important first.

  4. 04

    Hand it over

    The code and the accounts are yours. We can stay on for support.

What we build is yours to keep, with or without us.

Who you work with

Two brothers at the core, with four decades of engineering between them.

Kraig
KraigFounderKraig founded the shop and is the engineer who answers when you call. He has spent his career building software for startups and enterprises, and now builds it through the family business.
Adam
AdamLead engineerAdam leads the engineering. Between them the brothers have built for enterprise, finance, healthcare, and startups. Cloud native, full stack from the database to the screen.
Jackson
JacksonShop dogJackson is Kraig’s golden retriever. He sits in on every meeting he can get into, checks every bag for snacks, and is the only one here who never talks about software.

Our team’s experience includes

Where we built software before Rau Tech.

  • Allstate
  • bp
  • Health Catalyst
  • Starbucks

Small at the core, on purpose. We take your project from scope to handoff. When a build needs the bench, the engineers who join have shipped with us before and work the way we do.

The people you meet are the people who build it.

Tell us what you’re building.

Custom software, a new website, or a system that needs sorting out. A rough idea is plenty.
