Side-by-side comparison of AI visibility scores, market position, and capabilities

About
Nooks is an AI Sales Assistant Platform (ASAP) founded in 2020 by Stanford alumni and headquartered in San Francisco. The company raised $70 million in total venture funding including a $43 million Series B led by Kleiner Perkins. Nooks has achieved 4x year-over-year revenue growth and expanded to 90 employees by end of 2025, earning G2 Leader status in the Auto Dialer category for four consecutive quarters.\n\nNooks has evolved from a parallel dialer and virtual sales floor into a comprehensive platform with three AI-powered pillars: the AI Dialing Assistant (power and parallel dialing with automatic bad number detection and voicemail drop), the AI Coaching Assistant (call transcription, performance scoring, and AI-driven role-play for rep development), and the AI Prospector (account research, buying-signal detection, list building, and personalized email drafting). Together these tools automate the most time-consuming parts of sales development work.\n\nThe platform is especially popular with SDR-heavy organizations that need to maximize call volume and conversion rates while simultaneously coaching reps. Nooks competes with Orum, Dialpad, and traditional parallel dialers but differentiates through its all-in-one workspace that combines dialing, prospecting intelligence, and coaching in a single interface—reducing the tool sprawl that plagues modern SDR teams.
