Summit Partners — funds, providers and filings

The US-reported view

The sections below draw on US regulatory filings — SEC Form ADV and Form D — and on US investors' own disclosures. They set out Summit Partners's US-reported slice: the funds, service providers, domiciles and activity visible in US filings, not its worldwide business.

1. US-SEC private funds

This page reports $38.9bn of gross asset value across 119 private funds that Summit Partners reports on SEC Form ADV, filings through 2024. Its firm-wide figures are in the Assets summary at the top of this page, measured on a different basis.

Worldwide, 83 registered fund vehicles are on file under its management companies, on the worldwide entity register (read 2026-10-05) — these are legal fund entities, not the share classes or products a manager markets.

2. Service providers

EY audits 119 of the 119 Summit Partners funds that name an auditor on Form ADV Schedule D, filings through 2024 — more than any other firm. Morgan Stanley administers 14 of the 14 that name an administrator, on the same filings. Relationships the filings attribute to Summit Partners's own group are part of its structure, not third-party appointments, and are left out of these counts.

Across the funds that disclose each role on Schedule D — the count is funds naming that provider, of funds disclosing the role at all:

3. Fund domiciles

85 of Summit Partners's 119 SEC-reported private funds are domiciled in Delaware, its largest single domicile on Form ADV, filings through 2024. Cayman Islands is next, and the bars below give the rest in order.

4. Fund filing activity

SUMMIT PARTNERS SUSTAINABLE OPPORTUNITIES L/S FUND LTD. is the largest US raise on file for a Summit Partners fund: $782m sold to date, on its 2026 Form D filing. Amounts are cumulative sold-to-date figures as filed. They cover a fund's life up to that filing, not a single fundraise, and a fund that raises outside the US files nothing here.

The largest of the 8 US private-fund filings for Summit Partners's funds, by amount sold to date as filed.

5. Fund performance

Every figure here is a disclosing pension plan's own, on that plan's own reporting date. Nothing is blended into a manager-level return, because no plan published one.

Per-fund net IRR, multiple and DPI as disclosed by the pension plans invested in the funds — the LPs' own numbers, on their own dates, not the manager's. One row per plan disclosure. Where two plans hold the same fund and report different numbers, both rows show, with their dates:

Young vintages sit in the J-curve: an early negative IRR mostly reflects fees drawn before value is realised, and is not a verdict on the fund.

6. Known LP investors, from their own disclosures

CalSTRS (13), Minnesota SBI (5), CalPERS (2), NYC Fire (1), NYC Police (1) — the count is this manager's funds appearing in that plan's disclosure.

7. Management entities

Summit Partners files Form ADV through 3 management entities; the largest is Summit Partners, L.P., CRD 135271 of BOSTON, with 93 of the 119 funds on this page. Every figure above rolls those filers up into one business. The table below traces each of them back to the entity that filed it, so a number can be checked against its own record rather than taken on trust.
