Nooks, a San Francisco-based startup, has raised $43 million in a Series B funding round led by Kleiner Perkins. Existing investors Lachy Groom and Tola Capital also participated in the round, bringing Nooks’ total funding to $70 million. Founded by CEO Dan Lee and his Stanford classmates Rohan Suri and Nikhil Cheerla in 2020, Nooks is an AI-driven sales assistant platform designed to help sales teams increase efficiency by automating time-consuming tasks.
The platform offers a suite of AI assistants, including the AI Dialing Assistant, AI Coaching Assistant, and AI Prospecting Assistant. The AI Dialing Assistant helps sales teams engage in more quality conversations by finding phone numbers, skipping answering machines, leaving voicemails, conducting pre-call research, and taking notes. Teams using this feature typically see a 2-3x increase in call volume and conversations.
The AI Coaching Assistant reduces ramp times and boosts conversion rates by transcribing and scoring calls to identify areas for improvement. It also simulates real-world conversations to prepare reps and includes a Virtual Salesfloor for remote and hybrid teams to collaborate and train. The AI Prospecting Assistant automates online research by identifying target accounts, recognizing buying signals, building prospect lists, and drafting emails.

It integrates with popular sales tools like Outreach, SalesLoft, Gong, HubSpot, and Salesforce and data tools such as Apollo, ZoomInfo, Cognism, and LeadIQ. “We believe sales is fundamentally human, and AI will empower reps—not replace them,” said Dan Lee, CEO of Nooks.
“We’re building AI assistants to automate the busywork in pipeline generation, so humans can focus on the human parts of selling.”
Sales organizations using Nooks have experienced a 2-3x increase in pipeline generation per representative since adopting the platform. High-profile customers like Seismic, Fivetran, Amplitude, Modern Health, and Verkada rely on Nooks, attributing over 70 percent of their sales pipeline to the platform. Mamoon Hamid, Partner at Kleiner Perkins, said, “Nooks is bringing AI to the sales process in a human way—enabling sales teams with AI assistants.
Their approach empowers thousands of sales reps and demonstrates their vision and capability to build a generational company.”
Alyson Watson, CEO of Modern Health, commented on Nooks’ effectiveness: “Nooks helps drive over 70 percent of our sourced pipeline. And my reps love Nooks. They’d quit if we got rid of it.”
The announcement follows significant momentum for Nooks, including a recent declaration in April and a continued 4x year-over-year revenue growth.
The company plans to use the new funding to further develop its platform and expand its team.
