Company profile

researched Aug 2026

Infusion Software, Inc., doing business as Keap and previously known by its Infusionsoft product brand, develops a customer relationship management (CRM) platform aimed at small businesses. The platform bundles marketing automation, sales automation and customer service tooling, with functionality that includes lead capture through landing pages and forms, automated follow-up sequences, email and text message marketing, invoicing, appointment scheduling and sales pipeline management. The stated aim is to consolidate customer-facing workflows that small businesses would otherwise run across disconnected tools, and to automate repetitive tasks.

The company is headquartered in Chandler, Arizona, at 1260 South Spectrum Boulevard, and is led by co-founder Clate Mask as CEO. Sources give differing founding years: Preqin records establishment in 2001, while a directory listing states 2004. Reported scale figures also vary by source, from a directory citing 15,000+ active clients, 500-1,000 full-time employees and $50-100 million in revenue, to Preqin's statement of more than 200,000 small business customers.

On October 31, 2024, Thryv Holdings, Inc. (NASDAQ: THRY) announced the closing of its acquisition of Infusion Software, Inc. for $80 million in cash, subject to adjustment, positioning Keap's marketing automation capabilities within Thryv's SMB SaaS platform.

Founding story

Sources state the founders are Clate Mask, Ezra Miller, Scott Martineau and Stephen Tracy, with Clate Mask as CEO. A company self-description notes that Infusionsoft started as a small business and that more than 50% of its employees had owned or worked at a small business.

Business model

Business-to-business software sold to small businesses. Following the October 2024 transaction, the company operates as part of Thryv Holdings, whose platform is marketed to small and medium-sized businesses.

Subscription-based. Customers select from service plans at multiple pricing tiers, ranging from basic functionality for startups to more advanced automation features for established businesses, and pay a monthly fee, producing recurring revenue.

Traction

Preqin cites more than 200,000 small business customers. A directory listing reports 15,000+ active clients, a 98% client retention rate and revenue in the $50-100 million range. After closing the Keap acquisition, Thryv stated the combined company has over 100,000 SaaS subscribers.

Latest developments

Thryv Holdings closed its acquisition of Infusion Software, Inc. on October 31, 2024 for $80 million in cash, subject to adjustment. Thryv said it would integrate Keap's marketing automation and AI-powered tools into its platform and that existing clients would continue to receive the same support levels.

Full profile — market position, technology, go-to-market, geography, history, risks & controversies

Market position

Described by Thryv as a prominent player in CRM and marketing automation for small and medium-sized businesses; classified by Preqin as a growth-stage software company in the CRM and sales & marketing software sub-industries.

Positioned as an integrated CRM plus marketing and sales automation suite built specifically for small businesses rather than larger enterprises, intended to replace multiple point tools; Thryv cited Keap's automation and AI-powered marketing tools and its partner channel as complementary additions to its own portfolio.

Technology

A cloud CRM platform combining marketing automation, sales automation and service tools: landing pages and forms for lead capture, automated follow-up, email and SMS marketing, sales pipeline management, invoicing and appointment scheduling. Thryv's acquisition announcement also references Keap's AI-powered marketing tools.

Go-to-market

Direct subscription sales alongside a partner channel; Thryv described Keap's partner channel as complementary and additive to its own direct go-to-market channels and as extending geographic reach.

Small businesses across sectors including health and wellness, retail and service-oriented industries; named client examples in a directory listing include The Rocket Company, Blue Chip Athletic, Optibike, Presidential Pools and Gleason Financial Group.

Geography

Headquartered in Chandler, Arizona, with a customer base primarily in North America and growing markets in the United Kingdom and Australia. Thryv cited the acquisition as expanding its North American presence and its reach in Europe and Australia.

History

Founded in Chandler, Arizona (2001 per Preqin; 2004 per one directory listing) by Clate Mask, Ezra Miller, Scott Martineau and Stephen Tracy. The company operated the Infusionsoft product before doing business as Keap, raised a $20 million growth round led by ORIX Growth Capital in October 2018, and was acquired by Thryv Holdings in a deal that closed on October 31, 2024.

Risks & controversies

Sources contain conflicting data on founding year (2001 vs 2004) and on customer counts (15,000+ active clients vs over 200,000 small businesses), and total funding figures differ between the internal record and Preqin's $20 million figure. No controversies are described in the sources.
