The Group

Learn to invest in startups from someone who has done it

The Johns Creek Angel Group is forming in Johns Creek, Georgia — a private circle of accomplished individuals who learn how early-stage technology investing works, then invest in it together.

It begins with education and grows into action — members who choose to can invest alongside the group, but the decision is always their own.

Led by Tuff Yen, a career venture capitalist, the group studies how professional investors source deals, conduct due diligence, structure investments, and build diversified portfolios — and puts that knowledge to work. The first gathering is a free educational seminar, with more to follow.

Direct Access

Learn from two decades of hands-on venture capital — not from a textbook.

Peer Network

Connect with accomplished professionals and entrepreneurs in the Johns Creek community.

Deal Flow Exposure

See the same kinds of opportunities institutional investors evaluate — with guidance on how to assess them.

Structured Education

A curriculum built on the real-world frameworks professional investors rely on.

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.

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.
