Nooks

AI sales floor combining a parallel dialer, virtual salesfloor, and prospecting agent that automates outbound calling and research for SDR teams.

Nooks was founded in late 2020 by Dan Lee, Nikhil Cheerla and Rohan Suri, who built the company around a specific problem in B2B sales development: outbound calling burns hours of an SDR's day on dead numbers, voicemail, and phone trees before a single real conversation happens. The company's first product was a parallel dialer that calls multiple numbers at once and connects a rep only once a live person picks up, paired with a virtual salesfloor where remote SDR teams could dial together the way they once did sitting in the same office. Nooks has since expanded into an AI Prospector that automates account research, list building and outbound email drafting, and closed a $43 million Series B led by Kleiner Perkins in 2025 to build out what it calls its AI Sales Assistant Platform, bringing total funding to roughly $70 million. Both Dan Lee and Nikhil Cheerla were recognized on Forbes' 30 Under 30 list for the company's growth. The company has built a substantial public review footprint for a B2B sales tool, with over 1,100 reviews on G2 and an average rating near 4.8, reflecting broad usage across SDR and BDR teams even as some users flag connection lag and spam-adjacent concerns with parallel dialing as a category.
