MainStreet

What MainStreet does

Mainstreet (legal entity MainStreet Work, Inc.) is a permanent-capital holding company founded in 2011 and headquartered in California that acquires and operates small, durable software and services businesses for the long term. Originally a fintech helping small businesses identify unclaimed tax credits — reportedly saving SMB customers over $200M in aggregate and an average of more than $100,000 per year — the company has since pivoted into a Berkshire-Hathaway-style acquisition platform that buys profitable sub-$25M revenue software companies and rebuilds them on a shared, AI-powered operating backbone covering finance, HR, legal, and infrastructure.

The portfolio spans three verticals: fintech (Mainstreet's tax optimization, Capbase for entity formation and cap tables, and Bench for bookkeeping); HR and recruiting technology (Recruiter.com, Employer.com, BountyJobs); and AI (Mainstreet AI, which deploys cross-portfolio capabilities such as the StotzGPT private generative AI platform for Stotz Equipment). The stated operating thesis is that shared resources and shared revenue across the portfolio — not standalone brand ownership — generate the bulk of the returns, supported by a 14-day offer-to-close process, zero traditional debt, and an explicit "no fund clock, no forced exits" holding philosophy.

Revenue is generated through subscription and recurring service fees across the portfolio, totaling approximately $84M in aggregate ARR across 16 active investments and 13 completed acquisitions, with a 21.4% net IRR since inception. In May 2025, MainStreet was acquired by Employer.com at a post-transaction valuation exceeding $700M for the combined entity; Mainstreet continues to operate as the permanent-capital brand within Employer.com's platform, with Jesse Tinsley as co-founder and chairman of Mainstreet Holdings.

Expansion highlights6 records

Direct peers

• Constellation Software: Permanent-capital acquirer of vertical-market software businesses that operates them long-term under a decentralised structure. Closest publicly traded analogue to Mainstreet's buy-and-hold software model with shared operating playbooks across hundreds of acquisitions.
• Roper Technologies: Diversified technology holding company that acquires niche software and engineered products businesses and holds them indefinitely with operating improvement. Comparable to Mainstreet's permanent-capital, software-centric holding model.
• Heico Corporation: Acquisition-driven holding company that compounds value by buying niche businesses and reinvesting cash flow. Long-duration, decentralized operating model closely aligned with Mainstreet's permanent-capital approach.
• Pilot.com: Tech-enabled bookkeeping and financial services platform for SMBs and startups. Direct competitor to Mainstreet's Bench brand and to its broader SMB founder-OS thesis of consolidated finance for small businesses.
• Found: Banking, bookkeeping, and tax platform built for self-employed and small business owners. Overlaps Mainstreet's integrated SMB finance offering (tax optimisation, banking, bookkeeping) for a similar founder/SMB customer.

Broad incumbents

• Berkshire Hathaway: The canonical permanent-capital holding company referenced explicitly by Mainstreet. Operates across many sectors with a long-duration capital base; broad incumbent analogue rather than a direct software competitor.
• Thoma Bravo: Large software-focused PE firm that acquires and operates vertical SaaS businesses. Comparable to Mainstreet in target sector (software) and operating-improvement approach, though structured as a finite-life fund rather than permanent capital.
• Vista Equity Partners: Enterprise software-focused PE firm with a shared operating-playbook model (Vista Best Practices) analogous to Mainstreet's shared AI platform. Differs structurally as a fund vehicle, not a permanent holding company.
• Intuit: Incumbent SMB financial software suite (QuickBooks, TurboTax, Mailchimp, QuickBooks Live) competing across Mainstreet's bookkeeping, tax-credit, and SMB-banking value propositions. Broad incumbent rather than a niche peer.
• Rippling: Unified workforce management, payroll, benefits, and IT platform for SMBs and mid-market — competes with the Mainstreet/Employer.com/Recruiter.com HR stack and increasingly the broader founder operating system.
