SaaS500 comparison
Growjo alternative
Growjo ranks fast-growing private companies. It builds its list from growth signals such as estimated revenue, employee counts, and funding events, publishes award badges for the companies it lists, and sells contact data for lead generation. It does that well, and it is free to browse.
SaaS500 answers a different question: who leads the SaaS market right now. The index ranks the top 500 SaaS companies by the measured web traffic of their primary domain, re-ranked every day. It covers the whole SaaS market, public giants included, not only private companies. Every company gets a full record page and a free embeddable rank crest. No account is required for any of it, and no company can pay to change its rank.
