How Nadav Keyson built Riverside
Keyson grew up in Amsterdam, where his Israeli parents had settled, and studied at the Universiteit van Amsterdam. With his younger brother Gideon he built Debater.tv, for online political debates: “Gideon would program every weekend … and I reached out to Dutch politicians,” he said (CTech). They turned the technology into a recorder for podcasts and launched in spring 2020, just before the first COVID lockdowns. Early customers included the Dutch news site Nu.nl, the NFL and Hillary Clinton.
“When investors arrived, we did not have a presentation. So, we showed them the payment system,” he recalled. He moved to Israel, where most of the team builds the product, and led Riverside from a two-person company to more than $100 million in ARR in six years.
