New York-based Slide was founded earlier this year by Farman-Farmaian, a former product lead at crypto exchange Coinbase, and Sam Hatem, who previously worked as a blockchain developer at event-betting platform Polymarket. Slide came out of stealth mode alongside the funding round in a closed launch working with a select handful of partners. The company expects to have a full, open launch by the end of the year, Farman-Farmaian said.
