Tonka Bay Equity Partners

What Tonka Bay Equity Partners does

Tonka Bay Equity Partners is a private equity firm founded in 1998 in Minnetonka, Minnesota, that acquires and partners with U.S. lower-middle-market companies in three defined verticals: highly engineered manufacturing, value-added distribution, and business services. The firm targets businesses with at least $10 million in revenue and EBITDA greater than $3 million, executing buyouts, shareholder liquidity events, recapitalizations, and growth and acquisitions support, and has completed 46 partner company investments since inception. Tonka Bay has raised more than $560 million of committed capital across four funds from institutional investors, family offices, and high-net-worth individuals, and explicitly excludes startups, turnarounds, financial institutions, real estate, and restaurants from its investment mandate.

The firm operates a sales-led, direct-outreach model rather than relying primarily on competitive auctions, proactively targeting owners in its three focus verticals who may benefit from what it describes as a patient and collaborative approach. Internally, Tonka Bay supports portfolio companies through add-on acquisition execution (90+ add-ons historically across the portfolio), management team augmentation, governance, board oversight, and operational improvements delivered via an extended network of operating partners and CEOs. Active platforms include Corporate Technologies (IT managed services for SMBs, expanded from 5 to 21 U.S. locations through 2024–2026 via 5 add-on acquisitions), Standard Locknut (heavy-duty bearing components), LightMart (outdoor industrial lighting distribution), Image AV (audiovisual production services), Professional Credit (healthcare receivables management), and Fenix Specialty Coatings. Recent realizations include Seaway Plastics Engineering (sold to Intermediate Capital Group, 2022), Engineered Specialty Products (2023), United Skin Specialists (sold to Schweiger Dermatology Group, January 2024), and Orange Tree Employment Screening (sold to Accurate Background, June 2024), the last of which grew revenue and EBITDA more than 3x during Tonka Bay ownership.

Tonka Bay does not develop proprietary technology, and the firm itself has no AI/ML infrastructure or in-house engineering team; its "products" are equity capital and operational partnership services delivered to portfolio companies. Revenue is generated through standard private equity economics — management fees on committed capital, transaction and monitoring fees on portfolio activity, and carried interest on realized investments — with all fee structures privately negotiated and not publicly disclosed. The firm maintains 11–50 employees and a single headquarters at 301 Carlson Parkway, Suite 325, Minnetonka, MN 55305, and originates deals through direct outreach, referral networks ($5.5M in referral fees paid out historically), industry events, and selective advisor relationships (e.g., JEGI LEONIS on the CAMP Digital transaction, IT ExchangeNet on the NuMSP acquisition).

• HCI Equity Partners: Minneapolis-based lower-middle-market PE firm focused on industrial, distribution, and business services platforms with add-on acquisition strategies. Craig Bunker (Tonka Bay's Director of Business Development) joined from HCI Equity Partners, and the firms share a highly comparable lower-middle-market, Midwest-rooted investment thesis.
