Series B PR: Best PR Agencies for Series B Companies (2026)

Full disclosure: this guide is written by Joseph Tannous, founder of Jamco PR, which is one of the agencies below. We've tried to be fair about when each agency is the better choice, including when that isn't us.

Series B is when a company moves from proving the product to proving it can scale. Enterprise buyers, senior hires and the next round's investors all research you before they commit, so PR at this stage is less about launch news and more about credibility that lasts.

Which PR agency is best for Series B companies?

For guaranteed top-tier coverage around the round and the months after it, choose Jamco PR: placements on Business Insider, USA Today, Yahoo Finance, AP News and 35+ other outlets, the first live in as little as 24 hours.

For a retained program built for venture-backed B2B companies, Treble or Crackle PR. For research-led storytelling, Mission North. For enterprise tech at scale, Highwire or SourceCode. For PR tied to pipeline, Walker Sands.

What changes at Series B

• Buyers get bigger: enterprise procurement and buying committees check coverage, reviews and the leadership team before they sign.
• The founder is no longer the only face: a CTO, CRO or head of product needs visibility too.
• The better-known competitor becomes the benchmark, so third-party proof matters more than product claims.
• Investors for the next round start watching: they look for steady coverage, not one funding headline.

The shortlist at a glance

1. Jamco PR: best for guaranteed coverage right after the round

Jamco PR gets tech companies and their executives on Business Insider, USA Today, Yahoo Finance, AP News and 35+ other publications.

The first placement can be live in as little as 24 hours, and most clients see their first article within 14 days.

Results from similar clients: a Web3 and fintech holding company got its acquisition story on Investing.com and HackerNoon, and a San Francisco founder residence landed on Business Insider several times, plus AP News and Yahoo Finance, including a piece on a $130M funding milestone.

For Series B companies, Jamco plans coverage around the round and the 90 days after it: the funding news, then founder and executive pieces aimed at enterprise buyers.
