SaaS Interviews with CEOs, Startups, Founders · 2026-07-16 · 20 min
How do you build a $16.5M vertical SaaS company with 24% EBITDA margins with zero paid acquisition, zero outside funding, and your wife as co-founder? Rohit Garg is the co-founder and CEO of Practice by Numbers, an all-in-one dental practice management platform serving 1,300 customers across 2,000 locations. He started building it in 2015 because his wife is a dentist and he was the one running SQL queries to answer her business questions. Today they are bootstrapped, profitable, and sitting on $2 billion in untouched payment GMV from their existing customer base.
