We lead and that means something

We lead about 95% of our rounds with a board seat, and back just 10 to 12 companies a year on purpose. High conviction, low volume, so you get the full weight of the team, not just a check.

B2B is all we do

It's the only thing we invest in. We know the buyer, the playbook, and the messy middle of adoption in a way a generalist never will. The narrower our lane, the more useful we are in it.

Our collective knowledge, on demand

Bonnie is our AI-powered knowledge base, built from what we’ve learned across 300+ seed rounds. Every Bonfire founder can access it to surface the right pattern, resource, or connection when they need it.

Track Record

Companies we’ve backed have created over $18B in exit value, including The Trade Desk, TaxJar, and Scopely.

THE ONE THING WE CARE ABOUT MOST

The Compounding Loop

We invest exclusively in AI-native B2B technology companies. To us, AI-native means intelligence is foundational to how the product works and improves, not a feature added later. The best of these products get sharper every time they are used.

WHO WE BACK

Builder-CEOs who live inside the problem.

They turn hard-won domain knowledge into AI-native products that learn from the work. We lead their seed rounds, then stay close as the product, team, and advantage compound.

“Not every chapter of a startup story is glamorous—and Bonfire gets that. In the hard moments, they lean in. No pretense, no posturing—just real commitment to helping you move forward and get back to building something iconic.”

“There's no other investor like Bonfire. It's simple, they show up, they keep their word, and they will grind just as hard as you.”

“I’m proud to call us a Bonfire company. Some VCs invest in momentum—Bonfire helps create it.”

“Mullen and the Bonfire team are that rare breed of VC—unflinchingly honest, impeccably ethical, and annoyingly right most of the time.”
