Propensity Ranks No. 70 on the 2026 Inc. 5000, Cementing Its Position Among America's Fastest-Growing Companies

AI-powered B2B marketing platform makes the Inc. 5000 for the second consecutive year, climbing more than 2,500 positions as demand for a new approach to ABM accelerates

BOSTON, Sept. 16, 2026 /PRNewswire/ -- Propensity, the AI-powered B2B marketing platform helping growth teams turn buyer signals into coordinated action and measurable pipeline, today announced it has been ranked No. 70 on the 2026 Inc. 5000, the annual ranking of the fastest-growing private companies in America.

The recognition marks Propensity's second consecutive year on the Inc. 5000 and a dramatic rise from its No. 2,591 ranking in 2025, reflecting continued growth as B2B organizations seek more precise and intelligent ways to identify and engage buyers.

"Reaching No. 70 on the Inc. 5000 is an incredible milestone, but what excites us most is what's driving that growth," said Sumner Vanderhoof, CEO and Co-Founder of Propensity. "B2B marketers are ready for a better way to go to market. They want to know who is actually engaging, understand which signals matter and turn those insights into coordinated action across marketing and sales. Our growth validates that the market is ready for that change."

Propensity's rise comes at a pivotal moment for B2B marketing. Traditional account-based marketing has relied heavily on account-level intent, fragmented technology and complex processes. Propensity takes a different approach, combining account- and contact-level intelligence with campaign execution and AI-powered orchestration to help revenue teams move from signals to action.

As demand for more intelligent and efficient go-to-market strategies grows, Propensity continues to expand its AI capabilities to help marketers build audiences, develop campaign strategy, create content and activate programs faster.

This momentum reflects Propensity's broader evolution from helping marketers execute ABM campaigns to building an intelligent go-to-market engine that connects signals, decisions and actions across the buyer journey.

"AI gives us an opportunity to fundamentally rethink how B2B go-to-market teams operate," Vanderhoof continued. "The future isn't about adding another disconnected tool or generating more signals. It's about creating an intelligent system that understands those signals, determines the right next action, and orchestrates that action across the teams and channels responsible for creating revenue."

Propensity's No. 70 ranking places the company within the top 1.4% of the 2026 Inc. 5000 and among the top 100 fastest-growing private companies in America.
