McKinsey-scale ownership transfer, SBA and BizBuySell activity, and the channels search funds, sponsors, and PE use to find Main Street sellers.

A large share of U.S. small and mid-sized businesses are owned by people at or near retirement. When those owners exit, the firm is sold, transferred to employees or family, or closed. The volume of that transition—and the messiness of finding a counterparty—is why succession is a private-market segment Highford watches closely.

How large is the wave?

McKinsey’s Institute for Economic Mobility estimates that by 2035 about six million U.S. SMBs will face ownership transitions as baby boomers retire, with more than one million firms as viable sale candidates representing up to $5 trillion in enterprise value (McKinsey PDF; chart summary). McKinsey also notes that more than half of small-business owners are over 55. Separate SBA-linked commentary has cited roughly ten million boomer-owned businesses changing hands between 2019 and 2029 (Fox Business). Definitions differ; the direction does not.

What closed deals look like now

BizBuySell’s Q2 2026 Insight Report counted 2,117 closed transactions—down 10% year over year—with a median sale price of $349,250 and about $1.8 billion in enterprise value that quarter. Brokers described selectivity, not absent demand: 48% reported rising Entrepreneurship Through Acquisition (ETA) and search-fund activity; 78% of buyers expected to use SBA financing (report summary; BizBuySell Insight).

SBA 7(a) change-of-ownership lending is a second tape. Analyses of SBA FOIA data put FY2025 change-of-ownership approvals at 7,533 loans totaling about $8.8 billion, up roughly 31% from FY2024 (SearchSphereSource; underlying files at SBA open data).

Who is buying

Search funds. Stanford GSB’s 2024 Search Fund Study recorded 94 new core search funds in the U.S. and Canada in 2023, a record in that series (Stanford 2024 study).
Independent sponsors. Industry surveys estimate 2,500–3,000 active U.S. independent sponsors (Headway 2025 white paper).
PE lower-middle-market funds, holdcos, and operator-buyers. BizBuySell reports a large share of “corporate refugees” seeking recession-resistant cash-flow businesses.

How buyers source today

Channels stack rather than replace each other:

Listed marketplaces — BizBuySell, BizQuest, DealStream, regional broker sites; Acquire.com and Flippa for online/SaaS-leaning inventory (Acquire seller pricing).
Intermediated networks — Axial connects advisors and capital providers with success fees and no buyer subscription (Axial).
Off-market data platforms — Grata, SourceScrub, Inven, and similar products sell private-company graphs and intent signals; Grata now exposes an MCP server for LLM workflows (Grata MCP).
Concierge / AI sourcing — newer firms automate thesis-driven outreach to owners; Rejigg positions owner listing as free with buyer-side success fees (Rejigg).
Communities — Searchfunder and ETA networks share teaser flow among searchers.

Pain is consistent: listed inventory is picked over; off-market outreach is noisy; owners distrust unknown emails; buyers pay either success fees or five-figure software seats.

Where an information marketplace fits

Highford’s model—free public-source listings, credit-gated human- or agent-submitted listings, AI matching, double-opt-in email intros, MCP/REST for agents, no cut of the transaction—targets the coordination failure between aging owners and professional buyers. It is not a broker-dealer and does not negotiate or close sales. Public FOIA and registry data can seed awareness; only an owner-confirmed listing should unlock a conversation.

Why introductions beat another spreadsheet

Most searchers already have a spreadsheet of targets. What they lack is a trusted path to an owner who has signaled interest—without paying a 5% success fee or waiting on a broker’s weekly teaser PDF. Double-opt-in email intros solve the spam problem for owners and the credibility problem for buyers. Free public listings built from government data create SEO and agent-crawlable inventory; credit-gated owner-submitted “open to conversations” listings create the scarce signal. That separation—public facts versus private intent—is the product design Highford recommends for this segment.

Regulatory posture matters. A platform that never negotiates price, never holds escrow, and never takes a success fee sits farther from business-broker licensing than a classic marketplace. State rules still vary; the design goal is information and matching, not brokerage.

Financing reality on Main Street

SBA 7(a) remains the backbone for many acquisitions: BizBuySell’s broker survey found 78% of buyers expecting to use it, even as underwriting tightened (Q2 2026 summary). SearchSphereSource’s reading of FOIA tapes shows median change-of-control loans near three-quarters of a million dollars in late 2025 samples, with acquisition loans averaging larger than the overall 7(a) book (SBA stats). Seller financing fills gaps when valuations and bank advance rates disagree. None of that changes the first problem: finding an owner who will take a meeting. Capital follows conversations; Highford’s lane is the conversation layer.
