Stone-Goff’s Bet: Turn Expertise Into a Product

The most useful sentence on Stone-Goff Partners’ website is also the least financial: “We help companies productize their knowledge and expertise.” It is a tidy description of an untidy job. A veteran consultant knows which questions expose a client’s real problem. An analyst-relations adviser can read the politics behind a research report. A rural-broadband engineer has seen enough networks to spot trouble before a diagram does. That judgment is valuable, but it traditionally travels one expensive hour at a time.

Stone-Goff, a private equity firm with offices in New York and Boston, invests in the businesses built around that sort of judgment. Then it helps make the judgment easier to deliver again: through software, data, repeatable workflows, subscriptions, acquisitions and sturdier management systems. The firm calls its territory technology-driven B2B services. The phrase matters because Stone-Goff is not pretending that every consultant should become a software company. The person remains in the loop. The aim is to give that person leverage.

The screenProfit first, promise second

The sourcing filter is unusually legible. Stone-Goff looks across the United States for companies with $3 million to $12 million in historical EBITDA. It favors business services, consulting, marketing, IT, outsourcing, and human capital and training. Founder-owners and corporate carve-outs are both welcome. Stable profitability takes precedence over a spectacular growth chart. Customer concentration, early-stage risk and unproven economics are reasons to pass.

That puts the firm in a useful gap. Venture investors generally need velocity and an enormous potential market; large buyout shops need scale. Stone-Goff can start with a company that is already useful, profitable and respected in a narrow corner of the economy, but has not yet built the infrastructure to sell its expertise broadly. It says it is typically the first institutional investor. For a founder, that can make Stone-Goff less like the latest name on a capitalization table and more like the arrival of an operating system.

The overlooked asset is not the service. It is the knowledge trapped inside the service.

The operating workFour ways to make judgment travel

Capital is the opening move, not the product. Stone-Goff says it works with founders and executive teams on M&A origination and execution and on value creation. In practice, its public case studies point to four recurring moves.

Consider The Channel Company. When Stone-Goff invested in 2016, the business was rooted in media and live events for the information-technology channel. Over five years it became an integrated marketing services provider, added cloud-focused consulting through an acquisition, expanded its data and insights work and navigated a leadership transition. At the 2021 exit, company management said services revenue had grown sixfold and EBITDA had nearly tripled. The lesson is not “events became software.” It is that a trusted niche audience became the base for a broader, more measurable set of services.

DSG Consulting offers a more literal example. Stone-Goff invested in 2017 when DSG sold customized sales-enablement projects. During the partnership, DSG invested in vPlaybook, a digital subscription product that helped clients deploy and reinforce the themes created during those projects. Its affiliate consultant network nearly tripled, while revenue and EBITDA posted double-digit growth from 2018 through 2021. The strategic engagement produced the insight; the subscription helped the insight stick around.

The portfolioDifferent niches, same mechanical question

The present portfolio makes more sense when viewed as a collection of narrow information advantages. JSI serves more than 600 telecommunications operators with engineering, regulatory, financial, compliance and managed services. FS Vector advises more than 100 active clients across fintech regulation, licensing, policy, strategy and technology. MissionWired combines fundraising services with proprietary data and software for nonprofits, healthcare organizations, universities and political campaigns. Spotlight works with more than 125 clients on analyst relations and influence, supported by a proprietary platform.

These customers are not buying generic transformation. They are buying fewer errors in regulated markets, faster access to donors, clearer influence over enterprise buyers or safer operation of complicated infrastructure. That is Stone-Goff’s differentiation from a generalist sponsor: it is looking for service companies whose domain knowledge solves an expensive, persistent problem in one defined end market. Technology then amplifies credibility already earned in the field.

The May 2026 investment in 5Q Partners follows the pattern almost too neatly. 5Q provides IT infrastructure, cybersecurity, operational technology and advisory services to commercial real estate owners and operators. It serves more than 80 clients across more than 950 properties. At the same time as Stone-Goff invested, 5Q acquired One11 Advisors, adding support for major property-management applications. One transaction supplied capital; the other widened the service map around the same customer.

Stone-Goff’s companies do not sell “technology.” They sell familiarity with a costly problem, made easier to repeat.

The economicsWho pays, and how the firm gets paid

Stone-Goff has two sets of customers. Limited partners commit money to its funds. Founders and management teams accept that capital, along with the governance and operating involvement that accompany it. The firm seeks returns by increasing the value of portfolio companies and eventually selling them, recapitalizing them or moving them into a continuation vehicle. Its fourth flagship fund closed at $175 million in June 2023.

For the portfolio company’s own customers, the model is less abstract. A broadband operator can buy engineering and compliance support from one specialist. A fintech team can move between licensing, policy and technology without assembling a new bench of advisers for every question. A nonprofit can connect fundraising strategy to the data used to find its next donor. Bundling those adjacent jobs can deepen the relationship, but the more important benefit is continuity: the provider sees more of the customer’s operating picture and can build tools around patterns that recur. That is where a service engagement begins to resemble a platform without giving up the people who make it credible.

A 2022 transaction around JSI shows another route. Instead of selling the rural-broadband specialist outright, Stone-Goff created a single-asset continuation fund that acquired a majority interest from an earlier Stone-Goff fund. Pantheon led the new vehicle, abrdn Private Equity joined it, and existing Stone-Goff investors and partners could reinvest. The structure gave the manager and company more time to pursue acquisitions and organic growth while offering liquidity to earlier investors.

This is not a frictionless model. Productization can become a euphemism for imposing software where clients prefer people. Acquisitions can create a pile of adjacent capabilities without creating an integrated company. Recurring revenue is attractive to owners, but customers will renew only if recurring value appears on their side of the invoice. Stone-Goff’s published emphasis on end-market focus and proven profitability is one answer: begin with a customer problem that already pays, rather than a product theory in search of one.

The peopleA partnership built from two prior careers

Hannah Stone Craven and Laurens Goff founded the firm in 2010 by combining two predecessor partnerships, Ayr Capital Management and Goff Management. Craven had spent 13 years at Sandler Capital Management investing in media, marketing services and information businesses. Goff had spent more than eight years at Hampshire Equity Partners sourcing and managing middle-market investments. The firm’s name is the founders’ surnames joined by a hyphen - a piece of branding so literal it becomes a useful reminder of the partnership underneath.

The organization remains compact. LinkedIn lists 19 employees and describes the company as having 11 to 50. The public team includes investment professionals, a portfolio-operations principal, a head of business development and operating advisers. Its annual management summit convenes founders, executives, board members and outside experts across the portfolio. In 2026, the firm promoted Matt Gibbons to managing director and Dave DeFelice to principal of portfolio operations, highlighting data-driven decision-making, scalable operations and practical AI adoption in their remits.

The competitors are other lower-middle-market sponsors, growth investors, strategic buyers and private-credit providers courting the same founder. But Stone-Goff also competes with inertia. A profitable specialist can keep distributing cash and doing excellent bespoke work. To take institutional capital is to believe that its know-how can become more than the sum of its billable hours - without sanding away the judgment that made the company valuable.
