Leadbay
Leadbay is a Y Combinator (F25) B2B sales startup building a domain-specific AI model that discovers and qualifies small-to-mid-sized business leads that traditional platforms like LinkedIn, ZoomInfo, Apollo, and Clay can't find. Trained on market data, a company's own CRM/ERP history, and reps' instincts, Leadbay learns a team's Ideal Customer Profile and predicts who will buy next - delivering qualified leads directly inside agentic workflows and AI apps like Claude, ChatGPT, and Copilot. Customers in data-scarce industries such as construction, hospitality, manufacturing, and B2B services report roughly 3-5x more qualified prospects. The company raised a $4.3M seed round led by Y Combinator in May 2026 and is based in San Francisco.
Pecan AI
Pecan AI is an Israeli-American software company that builds a predictive analytics platform aimed at business teams rather than data scientists. Founded in 2018 by computational-neuroscience PhDs Zohar Bronfman and Noam Brezis, Pecan combines automated machine learning with large language models - a category it calls Predictive GenAI - so analysts can describe a business problem in plain language and get production-ready predictive models for churn, customer lifetime value, demand forecasting, lead scoring and campaign ROI. The company has raised roughly $127M, including a $66M Series C in 2022 led by Insight Partners with GV and GGV Capital, and in 2025 launched DemandForecast.ai for supply-chain forecasting.
Warmly,
Warmly, is a San Francisco-based AI revenue orchestration platform built for SMB sales teams. It identifies anonymous website visitors at the person level, aggregates real-time buyer intent signals from multiple sources, and deploys AI agents to orchestrate personalized outreach across email, LinkedIn, and ads - all within seconds of a prospect showing interest. Founded in 2020 by four ex-Google engineers and backed by Felicis, NFX, and RTP Global with $21.5M raised, Warmly, turns the classic problem of 'who is on my website?' into a fully automated pipeline generation engine.
Nutshell
Nutshell is an all-in-one CRM and growth platform built for B2B small and mid-sized businesses that are tired of overpaying for software they barely use. Founded in 2009 in Ann Arbor, Michigan, Nutshell combines sales pipeline management, email marketing, and customer engagement tools into a single subscription — with free live support on every plan. Acquired by digital marketing agency WebFX in 2022, Nutshell now serves over 5,000 companies across 50 countries, competing against industry giants like Salesforce and HubSpot by doing less, but doing it better.
