Fired by His Own Co-Founder, Then Built the #1 Startup Accounting Platform | David Phillips, Fondo

David J. Phillips tried co-founders four times before he went solo. With $40,000 left in the bank after a stalled aquihire, he refounded the company alone — and built Fondo, the accounting platform now used by hundreds of YC and pre-seed startups. The conversation is part founder-confessional, part early-stage GTM playbook. Topics covered: The four co-founder breakups across four prior startups Refounding with $40K and a single investor email The lived playbook for co-founder breakups (lawyer advice, severance + stock + move on) The four-question $40K filter for picking ideas you can ship solo The Sam Parr false bottom — first customer, three months of nothing The Delaware-franchise-tax mini-product wedge that produced the first ten paying customers Bear case and bull case for solo founding "Your co-founder lives in Claude now" — the closing argument Guest: David J. Phillips — founder & CEO of Fondo, the accounting and tax platform for venture-backed startups.
