NOVA
, we are managing a key position for one of our clients: a
Y Combinator–backed AI startup
based in New York that is transforming how Saa S companies deliver product demos.
Their product enables instant, hyper-personalized demos in any language—without the need for a human sales rep. The AI agent learns how any software works, joins live video calls with prospects, and, through a real browser,
navigates, explains, and interacts with the product in real time
.
This is a complex and high-impact problem, with future applications in onboarding, support, enablement, and automation. They are building something that
was not technically possible just a few months ago
.
