Onfolio is a holding company that acquires and operates small online businesses, targeting companies generating up to $5M in annual cash flows. Onfolio's portfolio is concentrated in B2B SEO and digital marketing agencies, including Eastern Standard, RevenueZen, DDS Rank, SEOButler, and Contentellect, with a recently launched GEO agency, Pace Generative, focused on AI search visibility. Beyond agencies, the portfolio includes Vital Reaction, a D2C molecular hydrogen supplement brand; ProofreadAnywhere, which sells online courses to aspiring freelance proofreaders; and a collection of content and publishing sites monetized via display ads and affiliate commissions. Agency businesses generate recurring monthly retainers from SEO and content marketing clients, while publishing sites earn passive ad and affiliate revenue. Onfolio also runs DealPipe, an M&A sourcing service that earns retainers and success fees. For businesses it manages but doesn't fully own, Onfolio earns management fees and profit shares through joint venture structures. Onfolio's acquisition thesis targets businesses too large for individual buyers but too small to attract institutional capital, arguing this gap offers attractive pricing and limited competition. The company funds deals with cash, equity, seller rollover, and SPV capital, emphasizing speed and certainty to close. Onfolio has increasingly prioritized acquisitions that can leverage existing portfolio companies, particularly in agencies and online courses.
