A waiting list can look like success until somebody reads it. By September 2022, according to Anderson Diehl’s later account, more than 600 people wanted to join Angel Investor Club. Many were startup founders. They had arrived at a community of investors and innovation leaders carrying a different set of needs. The queue was offering a clue: the people outside the door deserved a room of their own.
- A membership network for introductions, mentoring and investment education.
- Founder demand helped inspire a separate community, Founders Club.
- In October 2025, Founders Club acquired the investor club, adding 420 members.
The names on the list
Diehl says that discovery helped give rise to Founders Club in 2023. It is a pleasingly mundane origin for a business decision. Nobody needed to invent an audience. The audience had already filled out the forms. What needed changing was the assumption that everyone asking for access wanted the same thing.
Angel Investor Club had begun in 2021 as a way of giving back to an entrepreneurial world that had treated Diehl well. He had participated in startup exits, including Suiteshare’s sale to VTEX. Bringing useful people together offered a way to recycle experience as well as capital. Founders Club subsequently gave entrepreneurs a community organised around their own development.
The distinction matters. An investor wants opportunities worth examining. A founder may need help selling, hiring or getting ready to raise money. Put those people together and useful things can happen. Give them identical programmes and somebody may spend the afternoon politely listening to advice meant for someone else.
A club where the cheque is optional
Angel Investor Club describes itself as a network built by ecosystem participants for other participants. Its proposition includes exchanging knowledge, making connections and supporting entrepreneurs. On its public FAQ, the answer to whether members must invest is no. A person can contribute experience, help someone think through a problem or make an introduction without committing capital.
That widens the meaning of “angel”. The club’s community directory includes mentors, investors and other innovation participants, with locations ranging from Brazilian cities to Santiago, Orlando and Vancouver. Geography appears beside people’s names. The practical idea is that expertise need not live next door to the entrepreneur who needs it.
Its mission links entrepreneurship to employment and income. Its purpose page names cooperation, collaboration and avoiding competition as principles for participation. These are statements of intent, rather than proof of what every member experiences. Still, they explain the offer: a community in which helping another participant is part of the reason to belong.

What access costs
The public FAQ lists R$60 monthly or R$600 for a prepaid annual plan. Twelve monthly payments total R$720, making the listed annual option R$120 cheaper. Those are website terms, so an applicant should confirm the applicable price. Membership buys participation; it is separate from whatever money a member might eventually invest in a startup.
Applicants use a membership form and await approval. The published benefits include member meetings and access to experienced people. That is a service business with a human delivery mechanism: the value depends on who participates, what they know and whether they are willing to respond. A contact list by itself would make a rather expensive address book.
The expertise lives in the people
Fabiano Nagamatsu, independently identified as a co-founder, brings a background in startup mentoring and innovation. The wider founding group presented by the club includes people working in law, investment, strategy and business development. The breadth is relevant because an early company’s problems rarely arrive neatly sorted by profession.
In Brazil’s funding landscape, the club sits among angel networks, accelerators and venture investors. Its public directory includes Anjos do Brasil, FEA Angels and COREangels Atlantic. An entrepreneur could approach such organisations directly. Angel Investor Club offers a community through which people can learn about these routes and develop relationships across them. The same organisations can be alternatives and useful neighbours.
Two rooms, a connecting door
The acquisition announced in October 2025 put the two audiences under a wider umbrella. Founders Club brought in 420 Angel Investor Club members, taking the reported combined network to 1,100 participants. Angel Investor Club was to retain its format, with members gaining access to the broader Founders Club ecosystem.
Different audiences. Shared access to a wider network.
The reported R$35 million figure referred to money raised by startups in that ecosystem. It was neither the acquisition price nor club revenue. The distinction keeps the story in proportion: this is a business helping other businesses find resources. Its own transaction price was undisclosed.
A useful question before joining
Diehl’s February 2025 interview placed sales and a useful product ahead of the hunt for investment. That emphasis suggests a sensible way to approach the community. Bring a specific business problem. Ask for the expertise or introduction that could resolve it. Offer something useful in return. The advice is an inference from the club’s model, and a method a reader can copy without joining.
For a founder, a useful request might concern distribution rather than valuation: who understands this customer, and who has sold to them before? For a prospective investor, the first contribution might be a careful question or a piece of industry knowledge. These are ways to use a network deliberately. They also suggest a test for any paid community: can you describe the help you need clearly enough that another person can recognise it?
The conditions are straightforward. Relationships require attention; mentoring requires a founder willing to listen; investment decisions require their own scrutiny. Someone expecting membership to deliver an automatic cheque would be asking a community to perform a different job. The waiting list taught Angel Investor Club to notice those differences. Its most interesting asset may be the habit of reading the names carefully.
