Actionable Insights For B2B SaaS Founders

Dougal Cameron is CEO & Co-Founder of Golden Section, a Houston-based growth equity firm backing B2B vertical SaaS. Founded over a decade ago, the firm manages approximately $110 million and has invested in 50+ companies, writing $1–5 million checks into founder-owned software businesses and working alongside them from a few million in ARR toward $15 million and an exit. Golden Section is built to operate more like a school than a fund: alongside capital it runs a lending arm, a product engineering practice, and LookingGlass, its benchmarking and portfolio intelligence platform, and it publishes what it has learned — 169 mistakes and 70 plays drawn from 400+ companies — as an open, freely licensed playbook. In the firm's Enhancement Doctrine, Dougal argues that AI strengthens vertical software with real domain moats rather than displacing it. He began his career at the Federal Reserve, is a Rice University graduate, writes regularly on capital, craft, and stewardship, and lives with his wife and four children on 36 acres in Chappell Hill, Texas.
