AdButler
👤 Rajiv Khaneja (Started building web tools at 15; ran Sparklit profitably since 1998, and its cash flow funded AdButler's slow, VC-free growth.)🌐 siteLinkedIn
AdButler has sold a neutral ad server for 25+ years — profitable, never funded, while Google gives its own away.
Will it work? · our read
Patient and neutral. A free Google product owns the top of ad serving. AdButler survives by being the independent, publisher-owned server Google can't be — and by never needing outside money.
01How the money moves
A publisher or retailer needs to serve its own ads
→
AdButler runs display, video, native, and CTV across its sites and apps
→
It pays AdButler a subscription plus per-impression fees

Globe & Mail / Newsfile: 148% three-year revenue growth, Canada's Top Growing Companies 2025 STATEDNewsfile: FT Americas' Fastest-Growing Companies 2026, second year running (100+ servers, 1,200+ clients, founded 1999)AdButler blog: FT Americas' Fastest-Growing Companies 2025 (revenue growth 2020-2023)Mixergy: Rajiv Khaneja on building Sparklit and AdButler profitably, no VCCrunchbase: Sparklit — no funding raised (bootstrapped)
Revenue never publicly disclosed. The headline is AdButler's own figure — '148% three-year revenue growth' — printed in its press release on its 2025 Globe & Mail Canada's Top Growing Companies spot; STATED (self-reported to a reviewed ranking), not audited, and a growth rate, not a dollar amount. AdButler also made the FT Americas' Fastest-Growing Companies list in 2025 and 2026 (top 500 by revenue CAGR); the FT/Statista row with an absolute revenue figure was not reachable (the ig.ft.com interactive is blocked to fetching), so no dollar revenue is claimed. Client count (1,200+ organizations) and server count (100+ worldwide) are company-published on the openable press releases; '1T+ ads served annually' is from adbutler.com. Founder/CEO Rajiv Khaneja has run parent company Sparklit profitably since 1998; 'SparkLit has not raised any funding' (Crunchbase/Tracxn), and AdButler describes itself as 'independently owned and profitable since day one' — basis for the bootstrapped claim. No documented founder drama; this is a patience-and-independence story, not a single decisive gamble. Rival bar weights are our read of reach/mindshare, not revenue. verified:false because no first-party audited revenue figure exists to confirm. We never score you.
