Lusha Knows Who to Call. The Hard Part Is Knowing When.
The little browser extension that found a phone number has grown into a data layer for revenue teams and AI agents. It is quick, clever, and useful - provided you test its coverage before buying a mountain of credits.
Xiaohan Shen
Xiaohan Shen is the co-founder and CEO of Coldreach (YC W23), a San Francisco startup that uses AI to find ready-to-buy leads by watching public buying signals and to personalize cold outbound at scale. A University of Wisconsin-Madison computer science and data science grad, he calls himself an 'outbound nerd' after writing more than 1,000 cold emails by hand at his first startup, EasyJobs, which he and co-founder Hankel Bao grew to 20,000 monthly active users before pivoting into the tooling problem they lived themselves.
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.
Get Listings
Get Listings is a Sydney-based proptech company that helps real estate agents win more seller listings. It combines AI that scores roughly 14 million Australian properties daily for their likelihood to sell with a done-for-you advertising service that generates exclusive seller leads through Facebook campaigns. Agents can buy leads on a pay-per-lead basis or run a managed program, and track everything through a portal and mobile app. The company says it has served thousands of agents and generated hundreds of thousands of leads tied to more than a billion dollars in listed property.
Aidentified
Aidentified is a Boston-area AI company that maps who is wealthy, who they know, and when they come into money. Its platform combines 300M+ consumer and professional profiles with relationship graphs covering 16 billion first-degree connections to help financial advisors, wealth managers, insurers and nonprofit fundraisers find high-value prospects and reach them through warm introductions rather than cold outreach. Founded in 2017 and backed by financial-data giant FactSet, it delivers its wealth-and-relationship intelligence through a web app, CRM integrations, an API and data-as-a-service pipelines.
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.
Crunchbase
Crunchbase is a San Francisco-based platform that catalogs the private markets - companies, funding rounds, investors and the people behind them - and increasingly tries to predict what will happen next. Born in 2007 as a companion database to TechCrunch, it now serves millions of entrepreneurs, investors and sales teams, layering AI-driven funding and exit predictions on top of a dataset covering more than four million companies, sold through subscriptions, an enterprise API and CRM integrations.
LeadGenius
LeadGenius is a Berkeley-based B2B contact-data and buyer-intelligence company that blends machine learning with a globally distributed team of human researchers to build custom, compliance-first datasets for revenue teams. Rather than reselling a static database, it sources contact and account data on demand for each client, verifying every record before delivery, and layers in signals like role changes, technographics and buying-committee mapping. Spun out of the crowdsourcing startup MobileWorks in Y Combinator's 2011 class, the company pairs its data business with a social mission: it was the first crowdsourcing firm to tie worker pay to local living wages.
Redrob
Redrob is an AI company building large language models and go-to-market tools for sales, recruitment, and prospecting. Its platform combines a 700M+ contact data pool, verified emails, and real-time buying signals to help B2B teams find prospects, automate outreach, and screen talent. Founded by former international lawyer Felix Kim, Redrob positions itself as an affordable, enterprise-grade AI stack for emerging markets and cost-conscious companies, and aims to become one of the world's most-used LLM platforms by 2028.
Sumble
Sumble is a San Francisco AI startup building a knowledge graph of the world's external company data. Founded by Kaggle creators Anthony Goldbloom and Ben Hamner, it crawls job boards, company sites, social media, and regulatory filings, then uses large language models to surface technographics, org charts, and active projects for go-to-market teams. It emerged from stealth in October 2025 with $38.5M in funding and covers roughly 2.6 million companies worldwide.
Unify
Unify is a San Francisco-based AI go-to-market platform that automates "warm outbound" - combining intent signals, B2B prospecting data, AI research agents, and multi-channel email sequencing into a single workflow. Founded in 2023 by ex-Ramp outbound lead Austin Hughes and ex-Scale AI machine-learning engineer Connor Heggie, the company helps sales and growth teams reach buyers with personalized messages at the moment they are ready to buy. Customers include Cursor, Perplexity, Airwallex, Flock Safety, and Together AI. Unify has raised roughly $59M+ to date, capped by a $40M Series B led by Battery Ventures in mid-2025.

Surfe
Surfe is a connected revenue workspace that bridges LinkedIn and CRMs so sales teams can find, enrich, and sync prospect data without leaving their browser. Its browser extension and waterfall enrichment engine chain 15+ data providers to deliver verified emails and mobile numbers, and its buying-signal layer flags which prospects are ready to talk today. Founded in Paris in 2020 as Leadjet by David Maurice Chevalier and Romain Ginestou, the company rebranded to Surfe in 2022 alongside a EUR4M seed round, and now serves teams at companies like Google, Uber, Amazon Web Services, Spendesk, and Pigment.
David Chevalier
David Chevalier is the co-founder and CEO of Surfe, a Paris-born sales-tech company that bridges LinkedIn and the CRM. He and Romain Ginestou dreamed up the tool during an exchange at UC Berkeley after getting fed up with copy-pasting prospects into their CRM. Launched as Leadjet, the company bootstrapped to over 1,500 paying customers and 1M EUR ARR with no sales team before rebranding to Surfe and raising a 4M EUR seed round in 2022. Customers include Google, Uber, Spendesk, Mirakl and Opendoor. Chevalier is a vocal advocate for keeping the human in B2B selling, even as he builds tools to automate the busywork around it.
Nimble CRM

Ciro raised $3.8M in seed funding from CRV, Y Combinator, and SV Angel, and runs on a stack anchored by Anthropic Claude, OpenAI, and Elasticsearch. Outside the office, David self-identifies as an 'exceedingly obscure internet personality' and writes a personal blog mixing statistical deep-dives with essays on bike theft and vegetarianism.
