1/4 Founders (and to a lesser extent investors) move in generational cohorts.

These cohorts depend less on actual age, and more on when you started your company + market segment.

Cohorts emerge every ~4-6 years.

2/4 Founder cohorts/generations help each other out, provide peer advice, and bootstrap off each others' success.

Often have common overlapping networks and circles.

Today's core networks include Stripe, Uber, Twitter, Facebook, Google, SPC, YC & others.

3/4 Often founder cohorts have overlapping viewpoints and are exploiting a new platform or type of distribution.

For example, founders from 2008-2012 have tended to be against going public. Founders after that much more comfortable with it.

4/4 Feels like we have a new founder generational cohort emerging right now.

Bottoms up distribution, nocode/RPA, collaboration enterprise, "re-bundling virtual layer", fintech (APIs), new social products & other areas.

Exciting times.

(other key networks include:
Square, Lyft, Coinbase, Pinterest, Dropbox, Airbnb, Opendoor, French mafia, Affirm, Palantir, etc.)
