Built by people who understand operations
Not just code — software built by people who understand what actually slows a business down.
Trellis Stack
The complexity ends here.
Running a club or event shouldn't mean living in five different apps. We build software that actually simplifies the way businesses operate — starting with Ivy, the platform doing the work of a membership tool, a ticketing system and a communications team, all at once.

Guest pass sent for Friday — you're all set.
You've felt this before
A spreadsheet for members.
A separate site for tickets.
A group text — or three.
A payment processor that doesn't talk to any of it. By the time your next event rolls around, you're not running a club — you're running IT support for four disconnected tools that were never built to work together.

Ivy is where we started.
It won't be where we stop.
Every tool we build follows the same principle: take the complexity that's quietly draining your time, and make it disappear. Trellis Stack is building a growing family of software designed around that idea — one industry at a time.
50+ years of combined experience
Turning operational chaos into something that runs itself.
Simple by design
No bloated enterprise software, no six-week onboarding — just tools that work the way you already do.
Get started
Let's talk about your club.
Whether you're running a private club, a membership organization or a venue full of events — if you're duct-taping four tools together right now, we'd like to hear about it.
