Top 50 Lead Generation Software Companies With $10M–$100M Revenue (August 2026)

Chandler, Arizona, United States

Keap is a business automation and CRM software company targeting small businesses with annual revenues around one million dollars. The company originally focused on sales and marketing software for established small businesses before shifting down market toward startups and solopreneurs, a move that expanded its customer base but hurt retention. Keap has since reversed that strategy, returning its focus to more sophisticated small business customers and rebuilding its onboarding model around human coaching and goal-oriented product experiences. The company's return-to-growth effort centers on what it calls an integrated product-led growth approach, combining product-led elements with paid, human-assisted onboarding. A six-month experiment involving 705 customers demonstrated that goal-oriented coaching materially improved month-four retention and net revenue retention across customer segments. Keap now offers a 90-day coaching guarantee tied to specific customer goals, a departure from its prior allotment-based coaching model. The presentation was delivered at SaaSOpen in March 2024, a live event that drew approximately 1,000 software CEOs. The speaker described Keap's strategic arc from growth to decline and back, attributing the recovery to a redefined target customer, paid onboarding, and restored human connection throughout the customer lifecycle.

HighLevel is a software-as-a-service platform founded in 2018 and headquartered in Eugene, Oregon. The company helps marketing agencies automate multi-channel lead follow-up, including automated emails, text messages, phone calls, and voicemail drops, so that agencies can convert a higher share of the leads they generate for their small and medium business clients. At the time of its December 2018 interview, HighLevel was approximately six months old, had 10 agency customers paying $300 per month each, and was generating roughly $3,000 in monthly recurring revenue. The company was fully bootstrapped by founder Shaun Clark using proceeds from his prior exit and personal savings, with a two-person core team. HighLevel has since grown substantially. The company ranked 116th on the Deloitte Technology Fast 500 and 516th on the Inc. 5000, reflecting 781% growth. In 2021 PeakEquity Partners led a minority-stake investment of more than $60 million, and in 2024 General Atlantic led an additional undisclosed round, bringing total disclosed funding to $60 million.
