Founders.Tennis.Sunday mornings.

By invitation. Berlin and Hamburg. Established 2026.

A house, not a club.

The House Note

Founder Tennis is a house, not a club. Founded by founders, for founders, on grounds where tennis has been played for decades — long before software was built.

We know a founder's week. It is loud, long, and without natural end. We believe it deserves a counterweight. A white court. A steady hand. An hour where no one is selling.

Here, founders play with founders. Some have known each other for years. Some introduce themselves at the baseline. Membership is vouched for, not advertised.

We keep the court in order. We guard the calendar. We see to it that Sunday mornings stay quiet.

What happens here stays here. What is built here outlasts a quarterly plan.

If you understand why this matters, you are likely in the right place.

Yours,

The Format

Two cities. One rhythm.

Berlin and Hamburg. First Sunday of each month. 9:30 to 13:30. Doubles. Breakfast after.

The court is private. The conversation is unrecorded.
No solicitation. No pitching. No exceptions.

What happens between sets is the point.

Why Tennis

Padel is networking.
Tennis is ritual.

Padel happens in an hour. Tennis takes a morning. Padel is conversation between points. Tennis is concentration, broken by changeovers.

We chose the slower game on purpose. The court is tennis.

The Long Table

What happens after
the last set.

  1. I.
    Breakfast

    Breakfast is laid at one long table. No seating plan, no order of service. Conversation finds its own rhythm — some about the morning's tennis, much about other things. No one leaves before coffee.

  2. II.
    The Quiet Calendar

    Through the year, the house keeps a calendar of its own. A winter dinner in Berlin. A summer open in Hamburg. The occasional evening with a guest from outside our world. Members are notified. Nothing is published.

  3. III.
    What Remains

    Friendships, counsel, the rare introduction. These are not arranged for. They arrive on their own — between sets and across the table.

The Sundays are the foundation. What grows from them is the point.
