Series B Companies in the US

Overview

Series B companies have achieved product-market fit and are scaling into repeatable revenue. They have dedicated sales and marketing teams, a defined ICP, and real software budgets — but they're still evaluating and replacing tools as they move from startup infrastructure to enterprise-grade systems. This audience captures 3,300+ US Series B companies with verified funding data, tech stack detection across GTM functions, and C-suite and VP-level contacts.

What's Included

• Company Identity: Verified name, primary domain, and US headquarters location
• Funding Event: Series B round size, close date, and lead investor
• Board Composition: Known board members and investor representatives where available
• Headcount: Current employee count with department-level breakdown and 1-year growth rate
• Tech Stack: Detected tools across CRM, sales engagement, marketing automation, and data infrastructure
• Executive Contacts: Verified email and phone for C-suite, VP of Sales, VP of Marketing, and VP of Engineering

Use Cases

Growth-Stage SaaS Sales

Series B companies are in active replacement mode — swapping point solutions for platforms, replacing founders' tools with enterprise-grade systems. Tech stack data identifies which incumbents are in place and which categories are still unsolved.

Revenue Tech Stack Expansion

CRM, sales intelligence, revenue operations, and enablement vendors should prioritize this audience. Series B companies are formalizing their GTM motion for the first time and are evaluating vendors in every category of the modern revenue stack simultaneously.

VC and Growth Equity Sourcing

Growth equity investors and crossover funds can use this audience to identify Series B companies ahead of their Series C process. Filter by growth rate, industry, and round size to surface companies that fit specific investment theses.

Strategic Partnership Development

Series B companies are actively seeking distribution partners, technology integrations, and co-sell relationships to accelerate revenue without adding headcount. Use tech stack overlap and product category to identify natural partner candidates.
