What membership includes

National deal flow

Three to five vetted opportunities a year, sourced through Tuff Yen's nationwide network — not just Milton.

Financial return

A diversified portfolio of early-stage companies, built for asymmetric, long-term upside.

Community

Invest alongside experienced investors, operators, and founders who take this seriously.

Tax-deductible dues

Dues support the Seraph Research Foundation, a 501(c)(3) nonprofit, and may be deductible. Consult your tax advisor.

Education is open to everyone. Investing through the group is limited to accredited investors, as defined by the SEC — generally $200,000+ in annual income ($300,000+ jointly) in each of the last two years, or $1,000,000+ in net worth excluding your primary residence.

The Group

Learn to invest in startups from someone who has done it

Angel investing rewards the people who see enough opportunities, do the homework, and stay diversified. Alone, that is close to impossible. Together, it is achievable.

The goal isn't one lucky bet. It's a disciplined program that puts the power law to work over a decade.

Led by Tuff Yen, a career venture capitalist, the group works through real opportunities together — sourcing, diligence, structure, and portfolio decisions — so members learn the craft by practicing it. The group opened with a free introductory seminar in July 2026.

Why a group, not alone

Access

The best deals move inside trusted networks. A group's collective reach surfaces them.

Bandwidth

Real diligence takes 20+ hours a deal. Members divide the homework across the group.

Sample size

Two or three checks isn't a portfolio. A group builds one wide enough to matter.

Selection

Deals that find lone investors are often the ones professionals already passed on. Vetting is shared.

04
What You'll Learn

The knowledge that separates successful investors from the rest

Early-stage technology investing has produced some of the greatest wealth-creation events in modern history — yet most people never learn how it actually works.

01

Deal Sourcing & Screening

Learn how professional investors find high-quality startup opportunities and quickly identify which ones are worth pursuing — and which to pass on.

02

Due Diligence

Understand how to evaluate a founding team, assess market potential, analyze financials, and investigate risks before writing a check.

03

Portfolio Strategy

Discover why diversification is the key to angel investing success and how to build a portfolio that maximizes your chances of outsized returns.

04

Wealth Creation

See how the math works — why venture capital investing, done right, should be part of every qualified investor's portfolio for long-term wealth building.

Education — A Separate Program

The course series

Membership teaches by doing. For those who want to go further, an optional paid course series covers how venture capital works in practice — the financial and legal foundations, and the judgment to evaluate real opportunities. Offered through the Seraph Research Foundation, independent of the group: membership is not required to enroll, and the courses are not included with membership.

01Venture structure & the law
02How startups are built
03Evaluating the opportunity
04Terms & cap tables
05Reading the pitch
06Due diligence
07Exits & returns
Seven modules, one to two hours each — take the full series or choose individual modules.
Tuition and enrollment details are available on request; let us know on the form below.
The Power Law

A few investments return the entire fund

In venture, most startups return little — and a rare few return everything. That is why diversification is the heart of portfolio strategy: enough quality shots to catch the outlier.

A representative venture portfolio — returns, not counts.
