SEO for Tool Startups

NightEye is a dark mode browser extension launched in May 2018 that grew to 100,000 users and 4,500 paying customers through organic SEO. The bootstrapped side project from Razor Labs agency charges $9/year for subscriptions and $40 for lifetime licenses, generating approximately $2,500-$2,700 in monthly recurring revenue with an 86% annual retention rate.

Hashtag Pirate was an Instagram hashtag search engine that allowed users to find posts with multiple specific hashtags. Nicolas built the MVP in two months and achieved SEO success, ranking #1 for three keywords. However, the startup failed when Instagram/Facebook blocked API access in June 2016 to monetize their platform, making the core service non-functional before Nicolas could generate revenue.
