Brian Breslin

Brian has spent two decades building companies and mentoring the people who build them — students, side-project founders, and first-time operators in their first eighteen months.

The Venture Stack came out of that mentoring: the same conversation, hundreds of times, about ventures that were polished at the top and untested underneath. The framework is the map he wished he could hand every founder in the first meeting — six layers of claims, one founder bedrock, and a way to find the assumption whose failure would change the most.

He writes and teaches at first-venture scale — nights-and-weekends runway, campus ventures, first SaaS — because that's where the framework got its inspiration.
