What Each Costs
10 East and 3i Members charge in opposite ways: 3i through flat dues, 10 East through fees on what you invest.
Cost terms as each firm states them:
- 3i Members: dues of about $18,000 a year (CEO Teddy Gold, September 2025). 3i does not publish its dues and says it takes no fee or carry on investments.
- 10 East: a management fee typically of 1% a year, ranging to 2%, with carried interest on certain funds (Form ADV Part 2A, August 2026). 10 East does not publish its carry rates.
- Long Angle: free to join; 0.55% to 1.00% a year on what members invest. The fee rate is set at the time of each commitment and is reduced based on prior active commitments. No carried interest.
- All three: each option's investment vehicles bear their own expenses, and the underlying fund or sponsor charges its own fees.
Which costs less depends on how much you invest. Flat dues favor members who invest heavily and steadily; a percentage fee favors members who invest less or only now and then, and costs nothing if you don't invest.
How Each Chooses Investments
The main difference between the two is who decides what reaches members: 3i's members, or 10 East's team.
3i Members. Members bring opportunities. A five-person team screens them against a scorecard set by a quarterly member poll, then assembles members with relevant expertise to dig in. A member-led committee reviews about 120 opportunities a month and picks two, which go out by email and on a monthly call. CEO Teddy Gold says the committee chooses what will interest members and does not underwrite. Each member decides whether to invest.
10 East. Its team sources the opportunities. Since August 2025 an Investment Advisory Board has approved every offering before members see it, with final decisions resting with management. Members either join single opportunities one at a time or invest through a discretionary fund, launched in July 2026, in which 10 East picks the investments.
Long Angle. Our investments team finds and evaluates every offering, and negotiates terms for the group, before members see it. Members see the team's memo, including what it does not like, the manager's presentation, the documents and an open member discussion, and each decides whether to invest.
Who Can Join Each
3i admits by referral and by type of investor; 10 East admits by the SEC's investor tests; Long Angle admits by household assets.
3i Members requires a referral from a current member, and CEO Teddy Gold says members must be an exited founder, an active family office or a fund manager running $1 billion or more. Candidates speak with the team and go through background checks.
10 East offers its funds to accredited investors who also meet the qualified client or qualified purchaser tests. Its 2026 fund is open only to qualified purchasers, which for an individual generally means $5 million or more in investments.
Long Angle is open to people with more than $3 million in household assets, excluding a primary residence, and verifies them. Each investment offering states whether it is open to accredited investors or only to qualified purchasers.
How Each Is Regulated and What Each Discloses
10 East and Long Angle each operate through an SEC-registered investment adviser; 3i Members describes itself as a membership business.

Which Fits Whom
The right choice depends on how much you invest, who you want choosing, and whether you want peers for decisions beyond investing.
- 3i Members fits an exited founder, family office or large fund manager who invests steadily in private credit and private equity, wants to see member-sourced opportunities each month, and will spread flat dues across meaningful capital.
- 10 East fits an investor who wants a professional team to choose, either one opportunity at a time or by delegating entirely to its fund, and who meets the qualified purchaser bar for the fund.
- Long Angle fits someone who wants vetted peers across investing, tax, advisors and family decisions, may invest only sometimes, and prefers to pay nothing unless they invest.

10 East and 3i Members solve the same problem from opposite ends. 3i trusts its members to source and judge opportunities and charges flat dues for access; 10 East trusts its own team and charges on what you invest.
