Clay
Clay is a go-to-market (GTM) development platform that combines data from 130+ providers, workflow automation, and AI research agents into a single spreadsheet-style workspace. Teams use it to enrich records, find contact data through 'waterfall' lookups, research accounts with the Claygent AI agent, and trigger personalized outbound - turning growth ideas into automated systems. Founded in 2017 and based in New York, Clay serves more than 14,000 customers including OpenAI, Anthropic, Canva and Intercom, and raised a $100M Series C in August 2025 at a $3.1B valuation.
Monaco
Monaco is an AI-native sales platform - billed as 'the first revenue engine for startups' - that replaces the usual patchwork of CRM, outbound tools, and pipeline software with a single system. Founded in 2025 by former Brex CRO Sam Blond alongside his brother Brian Blond, Abishek Viswanathan, and Malay Desai, Monaco builds a company's total addressable market, runs outbound, captures every call and email, and manages pipeline using AI agents paired with embedded human sales experts. It launched from stealth in February 2026 and, three months later, raised a $50M Series B led by Benchmark, pushing total funding past $85M.
Kular
Kular is a London-based, Y Combinator-backed AI lead generation platform that finds and books qualified customers for businesses over email, LinkedIn, and AI voice - and only charges when it works. Instead of selling software seats or campaign hours, Kular runs the outreach itself and bills per positive reply or booked meeting, aligning its revenue with the results it delivers. The platform serves over 1,000 companies and is built by a team of MIT, Cambridge, and Oxford graduates.
Octave
Octave is a San Francisco-based AI company building a generative go-to-market platform - an 'agentic GTM brain' that codifies a company's ICP, positioning and messaging, then feeds that context to sales agents, workflows and tools like Clay, Salesforce and HubSpot. Founded in 2022 by Zach Vidibor and Julian Tempelsman, it has raised $8.4M total and reports 2,500+ GTM teams on the platform.
Nooks
Nooks is an AI Sales Assistant Platform (ASAP) that automates the grind of outbound sales - parallel dialing, prospect research, call coaching, and follow-up - so reps can spend more time having real conversations and less time leaving voicemails. Founded by three Stanford classmates in 2020 and headquartered in San Francisco, the company has raised $70M, including a $43M Series B led by Kleiner Perkins, and counts Seismic, Greenhouse, Brex, Deel, and HubSpot among its customers.
