For a GP seeking capital for a company investment, the relevant co-investor is the team whose mandate fits that company. That is a different proposition from asking an institution to subscribe to the GP's primary fund. Two Q3 2026 announcements make the distinction concrete: HarbourVest's HCF VII programme spans buyout and growth, while Hamilton Lane's Equity Opportunities Fund VI targets middle-market buyouts. ## Match the company to the named mandate HarbourVest's [July 10 HCF VII announcement](https://www.harbourvest.com/us/en/about-harbourvest/newsroom/press-releases/2026/harbourvest-partners-raises-4-75-billion-for-seventh-direct-co-investment-program) reported a final close of approximately $4.75 billion in total commitments. The global direct co-investment programme includes a dedicated fund that raised more than $500 million for growth-equity and expansion-stage opportunities, including AI, healthcare innovation and other growth industries. The growth fund is inside the programme, not additional capital to add to its close. That structure gives a growth-equity sponsor a more specific starting point than the overall fundraising headline. A company proposition can be matched to the stated growth mandate, rather than presented merely because HarbourVest is a large private-markets investor. For an LP, the buyout-and-growth architecture makes the intended investment mix part of manager selection. Hamilton Lane's [July 1 announcement](https://shareholders.hamiltonlane.com/2026-07-01-Hamilton-Lane-Holds-Final-Close-of-Sixth-Direct-Equity-Fund,-Raising-3-8-Billion-in-and-alongside-the-Fund) reported $3.8 billion committed in and alongside EO VI, without a fund-only split. EO VI seeks diversified exposure to middle-market buyout opportunities through the firm's global Direct Equity platform. Its stated mandate offers a different point of comparison from HCF VII's combination of buyout and growth capital. Recipient fit therefore starts below the firm name. HarbourVest's own release lists primary funds, secondary transactions and direct co-investments among its capabilities. A GP approaching the firm about a company investment needs the relevant direct co-investment strategy, rather than assuming that a relationship with one investment team covers all three activities. ## Build a transaction case for the co-investment team HarbourVest's [direct co-investment strategy](https://www.harbourvest.com/us/en/general-public/investment-capabilities/investment-strategies/direct-co-investments) defines the investment as an operating-company position alongside a lead sponsor. It describes evaluating opportunities with lead GPs, co-underwriting capabilities and portfolio construction. The company investment is the object of that work; the sponsor's fund track record is relevant background rather than a substitute for the transaction case. A useful GP approach should establish four things: what the company does and why the investment is attractive; how much capital is sought and its proposed use; the lead sponsor's role and investment case; and how the opportunity fits the recipient's stated strategy. These points give a specialist team something specific to assess, rather than another general request to back the sponsor. At platform level, HarbourVest describes investment capacity of $10 million to $350 million or more per transaction. That disclosure helps frame a sizing conversation around the company-capital requirement. It is not an HCF VII contractual check range or an LP subscription minimum. The GP still needs to identify the proposed investing vehicle and terms, rather than treating platform capacity as a commitment to a particular deal. This is also why stage matters. A growth investment needs a case for the relevant growth mandate; a middle-market buyout needs a case for that buyout exposure. Calling both opportunities direct equity does not resolve the investment fit. ## Underwrite the manager and the investment vehicle An LP considering the programme faces a portfolio decision. HarbourVest describes investment selection performed by its team and opportunities evaluated alongside lead GPs. The diligence subjects are connected: the companies selected, the sponsors alongside which the manager invests, and the process by which those choices become a portfolio. The LP can ask how buyout and growth positions fit its intended exposure, how company and sector concentrations are assessed, and whether investments held through other routes overlap with the proposed programme. An initial portfolio and the remaining investment pipeline would make that assessment more concrete. These are diligence questions, not claims about either programme's current holdings. Vehicle identification is particularly relevant to Hamilton Lane's announcement. Its broader Direct Equity platform includes commingled co-investment funds, evergreen vehicles and discretionary separate accounts. The release does not assign all those structures to EO VI or allocate the reported commitments among them. An LP needs the mandate and terms of the vehicle it is considering, rather than relying on the platform description as a complete account of its own exposure. Contractual fees, individual LP deal-election rights, allocation priorities and decision deadlines require offering and agreement-level diligence. The public announcements do not establish those terms. A description of diversified access is not itself a promise that every LP can choose each investment or receive identical allocations. ## Separate a deal offer from the authority to invest [Golden Gate's July 20 announcement](https://goldengatecap.com/golden-gate-capital-announces-final-close-of-fund-vii/) described co-investments it expected to offer its LPs. The existing Altss [buyout fundraising comparison](https://altss.com/blog/q3-2026-buyout-fundraising-final-closes-vehicle-boundaries) explains that prospective component. Its relevance here is the investor's next decision: considering a sponsor's offered company investment differs from selecting a specialist manager's portfolio-building mandate. The institution's implementation authority is another part of the decision. Altss's [September pension analysis](https://altss.com/blog/september-2026-pension-approvals-capital-boundaries) shows fund and co-investment structures appearing as separately named commitments, alongside differing deployment authorities. A manager-selection proposition needs to fit that institutional mandate as well as the investor's interest in the asset class. A practical diligence agenda puts the company case, the proposed investing vehicle and the approval authority beside one another. The opportunity is then specific enough to discuss its terms, rather than inferred from a large close or a familiar firm name. Share this article Share ### See Altss in action.
