Our Story

Slingr has built enterprise software since 2011. Founded by CEO Grace Schroeder, we watched companies bend their operations around rented software and prop up systems only one person understood, so we built a different model: senior engineers supervise AI to deliver custom software in weeks, and clients own the code, data, framework, and specs. Our 120+ product engineers in Miami, Mendoza, and Buenos Aires are trusted advisors who learn your business, not ticket takers.

What Sets Us Apart

15 years building software businesses run on

Since 2011, we've built and run the systems companies depend on every day, for manufacturers, labs, and healthcare providers, including Veritone, ChemQuant, and Ritchie Bros. SOC 2 Type II and HIPAA compliant. Most of our clients have worked with us for years.

AI makes it fast. Senior engineers make it work.

AI lets us deliver in weeks what used to take quarters, at a fraction of the cost. But AI on its own writes fragile software. Senior engineers design every system and review every line, so what you get is tested, documented, and built to last for years.

It's yours. No licenses, no lock-in.

You own the software we build and all of your data, like any other company asset. No per-user fees, no renewals, no vendor holding your business hostage. If you ever want to bring it in-house or switch providers, everything they need comes with it.
