SMARTe and the surprisingly expensive wrong number
A bounced email looks like a small mistake. SMARTe has built a business around what happens when thousands of those small mistakes become the way a sales team works.
Coldreach
Coldreach is a Y Combinator-backed (W23) AI sales development platform that helps B2B teams find companies that are ready to buy right now. Instead of blasting cold emails to random lists, teams describe what a buying signal looks like for their product in plain language, and Coldreach monitors 113M+ companies across job postings, news, LinkedIn activity, SEC filings, hiring changes and more, 24/7. When a match fires, the AI researches the account and writes personalized outreach that references the specific event - which the company says produces meaningfully higher reply and booking rates than spray-and-pray outbound.
Pocus
Pocus is an AI-powered product-led sales and revenue intelligence platform that helps go-to-market teams turn scattered product usage, CRM, and intent data into prioritized action. Founded in 2021 by Alexa Grabell and Isaac Pohl-Zaretsky, the San Francisco company tells sales reps which accounts to work, who to contact, and what to say by surfacing high-intent buying signals and generating AI account plans. Used by product-led companies including Asana, Canva, Miro, Monday.com and LaunchDarkly, Pocus raised $23M in seed and Series A funding backed by a16z and First Round Capital, and was acquired by Apollo.io in March 2026 to power Apollo's AI-native GTM operating system.
Starbridge
Starbridge is a New York-based AI go-to-market platform built for companies selling to government and education. It scrapes the messy, fragmented world of public sector data - board meeting minutes, budgets, RFPs, contract expirations and procurement records - and turns it into ranked buying signals, account intelligence and auto-drafted proposals so sales teams can find and win deals before the RFP drops. Founded in 2024 by Coursedog veteran Justin Wenig, it has raised $52M total, including a $42M Series A led by Craft Ventures in October 2025, and serves 160+ enterprise public sector sales teams.
