Shodan
👤 John Matherly (Conceived internet-wide scanning in 2003, then crawled every IP for years solo — a dataset and security cred no rival could rush.)🌐 site𝕏
One founder crawled the whole internet's devices and built the recon layer every security team now pays for.
Will it work? · our read
Owns the index. A scratch-your-own-itch turned critical infrastructure: 15 years of crawl data and security's default recon tool. Risk: lean, founder-central, with a VC-funded twin (Censys).

Shodan has never disclosed revenue. The "$1M+/yr" is our conservative floor [our read], inferred from public pricing ($49 lifetime; API $69-$1,099/mo Corporate) plus enterprise adoption and 15 years as category leader — not a first-party figure (not independently confirmed, EST). No VC rounds are on record; "self-funded/solo-founded" is [our read] from the absence of filings. Founding year, business model, and user base are documented (Wikipedia, Forbes, founder interviews). Censys as the funded twin is documented; its competitive threat is [our read]. We never score you.
