TeamGantt
👤 Nathan Gilmore & John Correlli (Both engineers, so build cost was near zero; they spent year one ranking for 'gantt chart,' launching to a 1,300-person list.)🌐 siteLinkedIn
A two-founder side project, four hours each Saturday, that won a giant's category by owning one keyword: gantt chart.
Will it work? · our read
Patient and durable. Fifteen years of patient SEO work built a real business. But the moat is one keyword and a feature giants can bundle free, so the ceiling is real.

SaaS Club podcast #427 (undated) — Nathan Gilmore states 7-figure ARR, 6,000 customers, 180 countries, about 21 employees, fully bootstrapped.TeamGantt pricing — free plan plus per-project paid tiers (Basic, Business).TeamGantt — About — company history and team.The Org — TeamGantt — co-founders John Correlli and Nathan Gilmore, founded 2009, Baltimore.
Revenue is first-party but imprecise: on the SaaS Club podcast (#427, undated — no publish date visible on the page) co-founder Nathan Gilmore said TeamGantt is 'well into the seven figures' in ARR — not audited, no exact figure. The 6,000 customers, 180 countries and about 21 employees come from that same interview and were verified in the page's raw text, not a summary. Founding facts (2009, Baltimore, co-founders John Correlli and Nathan Gilmore) cross-checked via The Org. Bootstrapped, no funding rounds. Pricing reflects the live pricing page; exact tier prices were not confirmable from raw HTML, so treat the $10-24/project range as approximate. Rival per-seat prices and mindshare weights are our read, not audited. We never score you.
