"Our team is going all-in on a new media venture, so AltIndex deserves an owner who can give it full focus. You get 71,000 accounts, 700+ paying web+mobile subscribers (76% on annual plans), a profitable SaaS grown mostly through organic Reddit, SEO and newsletters, and a B2B data API that just launched. Upside: sell data to quant funds and brokerages like Robinhood, expand into data on prediction markets and new social platforms, add affiliate and referral programs, and expand on marketing."
