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.
Kareem Amin is the cofounder and CEO of Clay, a New York-based go-to-market platform that lets sales and marketing teams pull data from dozens of sources and run AI-powered personalized outreach at scale.

A second-time founder and McGill-trained engineer, Amin frames Clay as a creative tool that gives non-programmers the power of code, and talks openly about meditation, founder psychology, and building 'from a place of wholeness.'
In this episode of 'Stories of Scale,' a host spends a full day inside Clay, the $5 billion New York startup that coined the term 'go-to-market engineer,' to figure out what this fast-growing role actually is. Shadowing Everett Berry, Clay's Head of GTM Engineering, along with teammates like Spencer, Varun (co-founder), and George, the video unpacks how GTM engineers blend engineering, marketing, and sales to build automated systems that find, understand, and reach customers. It also reveals Clay's two-team 'flywheel' — an internal pipeline team and a forward-deployed customer-facing team — that helped the company scale from five years of near-zero revenue to over $100 million and 16,000+ customers.
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.

The platform serves over 1,000 companies and is built by a team of MIT, Cambridge, and Oxford graduates.

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.

Zach Vidibor is the co-founder and CEO of Octave, a San Francisco-based AI go-to-market platform that serves as the context engine for B2B revenue teams. After 15 years selling for LinkedIn, DocuSign, Dropbox, and others, he grew frustrated watching company strategy dilute before it ever reached the frontline - so he built the fix. Octave, which raised $8.4M across pre-seed and seed rounds, lets GTM teams codify their ICPs, value propositions, and competitive positioning so AI agents can generate genuinely differentiated outreach instead of generic noise.
