Chrome plugin Startups

CellHack is a SaaS platform that helps salespeople find targeted prospects, build email lists, and verify email addresses. Founded by Ryan O'Donnell in 2014 after his previous startup failed, it started as an internal tool before being productized and monetized with a $9/month subscription plan. Within two years of launch, the company hit over $1 million in revenue, driven primarily by word-of-mouth growth and early media coverage on TechCrunch.

Lead Delta is a Chrome plugin that helps B2B professionals organize and leverage their LinkedIn networks for more effective selling. Co-founder Vedran Rasic launched it on Product Hunt and achieved remarkable traction: 499 customers on day one with a #1 product of the day ranking in year one, and repeated the #1 ranking a year later. The product has grown to 6,000 users organizing their LinkedIn connections with tags, notes, and personalized messaging features.
