Research updated September 5, 2026.
Some family offices invest directly in startups. Others commit to venture funds, buy established businesses, or manage client wealth without making startup investments themselves. For a founder building an investor shortlist, that distinction matters more than an estimate of the family's wealth.
The ten organizations below publicly describe direct startup investing or show relevant company holdings. They cover different stages, sectors, and geographies. This is an investor-research list, not a directory of personal contacts or a claim that each organization has capital available for your round.
How to read this list
We used official investment mandates, portfolio disclosures, and public approach instructions. Dated financing evidence is identified where available; an undated portfolio is not described as a new 2026 investment. Entries are alphabetical, not ranked by returns, influence, or likelihood of funding.
An explicit pitch invitation means the organization publishes a relevant submission route. It does not guarantee a response or investment. Where a route's destination needs checking, that limitation is stated. None of these entries is an introduction to an individual.
| Family office | Relevant startup fit | Public approach | Important boundary |
|---|---|---|---|
| Adeline Arts & Science | Pre-seed through Series A technology, science, climate and health | Official Pitch Us form | Creative and scientific projects are not necessarily startup-equity investments |
| AFP Capital | Pre-seed and seed, with an Italian ecosystem emphasis | Official startup application | Separate the Italian family office from the Chilean pension company of the same name |
| Exceller Hunt | Seed and Series A ventures | Venture-specific inquiry invitation | Energy, property and philanthropy have separate purposes |
| Gloucester Ventures | Pre-seed and seed biotech tools and platforms | Pitch Your Startup form | US, UK and Israel scope; not a generalist life-sciences mandate |
| J&S Legacy | Technology-company seed and early-stage portfolio | Site invites decks | Publicly dated examples are mainly 2024; confirm the current submission destination |
| Kapital Partners | Emerging technology, marketplaces, e-commerce and enterprise software | Official opportunity inquiry | Direct companies and external fund investments are separate mandates |
| Keller Capital | Early and growth-stage technology, including AI-native businesses | Submit a Deal form | Broad mandate does not mean every sector or stage is equally relevant |
| KG Investments | Venture-stage technology and private-tech transactions | Company-opportunity instructions | Primary financing, secondaries and structured deals are different transactions |
| McGovern Capital | Seed and early-stage companies with proprietary technology or IP | Business-summary instructions | Equity consideration can combine cash and facilitative services |
| Sachse Family Fund | Early-stage companies | Official deck-submission route | A wider venture network is not the same as a single principal's investment decision |
1. Adeline Arts & Science
Adeline identifies itself as a London family office backing pre-seed through Series A technology startups with a global outlook. Its stated interests include B2B, science, climate, health, infrastructure tools and AI. The portfolio distinguishes company stages, helping founders test fit beyond a broad technology label. Official investment approach.
Its Pitch Us route is explicitly for founders applying for investment. TaiSan's July 2026 seed announcement names Adeline Arts & Science, providing dated company-financing evidence. TaiSan financing announcement.
Approach Adeline with the scientific or technical advantage, intended customer, and next development milestone. Do not equate its support for the arts or research with a standard equity mandate for every project.
2. AFP Capital
AFP Capital describes itself as an independent, privately owned family office investing mainly in startups. Its official approach emphasizes pre-seed and seed financing, traction, innovation and sustainable growth. The office is based in Rome, and its portfolio gives founders a useful view of its Italian ecosystem activity. Mandate and startup application.
The official portfolio includes ilmiobrokerassicurativo. Gallagher Re's Q1 2025 transaction research lists AFP Capital among that company's financing participants. This is dated independent corroboration, not an announcement of a new allocation available today. Portfolio, Gallagher Re transaction report.
Use the linked startup application. The office says it responds to projects it finds interesting; submission is not assurance of a meeting.
3. Exceller Hunt
Exceller Hunt is a Dallas family office whose website explicitly identifies seed and Series A venture investing and invites related inquiries. Its other areas include energy, real estate and philanthropy, which should not be blended into one startup mandate. Official venture section.
Mobia Medical's May 2026 securities filing identifies an associated Exceller Hunt vehicle in 2025 financing and early-2026 convertible-note participation. That supports actual company-investment activity, while neither setting a standard check size nor promising capacity for a new company. Issuer filing.
A founder should identify the relevant venture stage and explain company fit. A request to the foundation is not a shortcut into the investment process.
4. Gloucester Ventures
Gloucester Ventures identifies itself as a single-family office focused on pre-seed and seed biotech tools and platforms in the US, UK and Israel. Its stated scope includes a path toward funding and commercial partnerships in the US. Investment thesis and pitch form.
Its principal's public 2025 recap names investments including AGED Diagnostics, NetwoRx Bio and eGlint. Treat those as activity examples, not independent validation of their clinical claims or investment performance. Principal's investment recap.
The official pitch form requests a company name and deck link. Explain the platform or tool, evidence quality, commercial path and geographic fit. A general healthcare pitch may not match this narrower thesis.
5. J&S Legacy
J&S Legacy calls itself a single-family office based in the US and East Asia. Its company portfolio lists named seed and early-stage investments, including DYAD AI, Vantage Robotics, TrueVault and Magic Hour AI, with stage and year labels. Those labels mainly describe 2024 activity, not a claim of new financing in 2026. Official portfolio.
The site says it is looking for investment opportunities and invites decks. Confirm the live submission destination before sharing materials; the public page does not establish a specific US-state office or a universal geographic eligibility rule.
This is a technology-company research prospect. Its separate reference to funds and alternative assets does not, by itself, establish a mandate for your venture fund.
6. Kapital Partners
Kapital Partners manages Nanda-family investments from Campbell, California. Its direct-investment page explicitly covers emerging technology and startups, with interests including consumer marketplaces, e-commerce and enterprise software. It names past company investments, but does not date every holding. Direct-investment mandate.
The office also invests through other asset classes and external funds. A founder should make clear that the proposal is for company equity, rather than assuming a broad private-equity or venture-fund label identifies the relevant decision process. Its official site provides investment-opportunity inquiry information.
Use the current thesis and company evidence to establish relevance. Do not infer lead behavior, a typical check, or available capital from a familiar portfolio logo.
7. Keller Capital
Keller Capital identifies itself as the Keller family's Austin-based single-family office, investing its own permanent capital. Its current venture and technology focus includes early and growth-stage companies, with particular attention to AI-native businesses. Official investment mandate.
Its Submit a Deal form explicitly addresses founders, operators and sponsors and asks for information about the opportunity and supporting materials. That is different from its general-inquiry channel.
The public mandate is broader than startup equity and also includes property, credit, buyouts and fund interests. Be specific about the proposed security, company stage and capital use. We have not inferred a recent individual transaction from the site's founding date, copyright date, or aggregate investment claims.
8. KG Investments
KG Investments describes a proprietary technology-investment approach associated with the Kaplan family office. Its opportunity instructions address venture-stage companies, private-technology secondary positions and relevant transaction intermediaries. Official opportunity page.
Those routes describe different financing jobs. A startup issuing new equity should not present itself as a secondary-liquidity opportunity, and a shareholder seeking liquidity should not imply that proceeds finance company growth. The office's company-investment mandate is also not evidence that it makes primary LP commitments to outside VC funds.
Follow the relevant published instructions and explain the transaction structure. Current public materials do not establish a universal stage requirement, commitment size, or acceptance policy for unrelated advisory-service pitches.
9. McGovern Capital
McGovern Capital's official team page identifies a single-family office; its investment criteria explicitly cover seed and early-stage companies with proprietary technology and intellectual property. Its portfolio includes company-building and licensing activity, not simply passive capital allocation. Classification and activity, Investment criteria.
The criteria request a short business summary before a complete plan. Crucially, the proposed equity consideration may combine cash and facilitative services. Founders should evaluate the cash actually proposed, service obligations, ownership and governance separately.
Its official materials describe a January 2025 RISE Brewing portfolio exit. That is relevant activity, not proof of a new 2026 commitment to every applicant. Portfolio.
10. Sachse Family Fund
Sachse Family Fund identifies itself as a single-family office that builds, buys and invests in businesses. Its startup focus is early-stage companies, and its team page explicitly invites founders to submit decks. Official team and submission invitation.
The deck-submission page links into a Family VC deal form. That is an officially linked route, but the surrounding network should not be counted as multiple committed investors. TechPoint's 2024 venture report names Sachse among PAXAFE's investors; that historical evidence does not establish a fresh commitment today. 2024 transaction report.
Present the company, evidence of demand and reason for fit. Avoid assuming all participating family-office or angel-network members share Sachse's mandate.
Build a shortlist around the proposed investment
Compare the company's stage, industry, geography and financing structure with each published mandate. Separate primary startup equity from secondary shares, structured credit, cash-and-services arrangements and fund commitments. These are not interchangeable sources of financing.
Keep an evidence date next to each prospect. A live website can state a current strategy while its portfolio examples are older. An explicit pitch invitation can remain open without a commitment to review your company. Record both facts instead of marking every contact as an active opportunity.
