Our team

Built by operators. Not enterprise software people.

We've run brokerages. We've felt the spreadsheet chaos at 11pm on a Sunday. We're not building software for software's sake — we're building the tool we wished existed.

Erwin Durmic

Founder & CEO

Founded Primitive Site Solutions in 2019 — a service brokerage that grew from a one-truck operation into a multi-vertical platform. Built Stacker Platforms after years of duct-taping Pipedrive + Quickbooks + Sheets + Gmail together.

Our values

What we believe.

Operators > vendors

If you've never run a brokerage you don't get to build software for one.

Ship the workflow

Every screen serves a specific moment in the lead-to-paid loop. No feature exists in isolation.

Honest pricing

No usage-based traps, no "call for pricing." Three plans, posted publicly.
