๐ Open Newsletter: CoFounder Weekly
Thereโs a trend of startups sharing their growth and user stats, a topic weโve covered a few times. Pat Walls of StarterStory, Sahil Lavingia of GumRoad and Buffer are great examples of this.
Isnโt it a bit hypocritical to cover the trend and not participate ourselves?
Weโve been pumping out one CoFounder Weekly every Sunday since August 2018. We started as a Twitter recap for those who donโt check twitter.

Weโve since broadened the scope of our content beyond curating tweets, making moreย originalย content. For example, last week we debuted a Day in the Life segment and a compilation of Out of Office emails.
Our readership growth has been linear in 2019. Each bump in the chart below was an instance where a reader tweeted about us or shared our newsletter on LinkedIn, which typically generates about 20 new subscribers. Weโve also been manually signing up subscribers at conferences, weddings, bar mitzvahs, at the DMV, and in line at Sweetgreen.

Who subscribes? A mix of founders, operators, investors, and startup enthusiasts.
Most of our subscribers are in the US, followed by Canada. The map below was pulled in Clearbit, which enriched our email subscriber data.

Our open rate has consistently been in the 50-60% range, which is super solid.

And the anecdotal feedback is encouraging!

Next step is to increase the volume of originalย contentย creation.ย Cartoons. Video. Provocative and weird essays. Behind the scenes. Etc.
We also just held a first writerโs room this week โ including a few friends who work in tech and have ideas they want to contribute. If you have ideas, let us know as well.
Weโd also love to hear from you what you like & donโt like, and where we can take this puppy.

๐ธ Funnies
(LOLs from this week)


๐ Challenge: Sizing the Market
Google, Amazon and other tech companies have been known for asking complicated brain teasers to employees.
Jeff Bezos used to ask questions like "How many fax machines are in the United States?"
As an experiment this week, we have a brain teaser challenge for our readers:
โHow many avocados will be consumed in the US this weekend?โ
While thereโs no right answer, the most creative one will win a special surprise announced next week. Send us your answer (and show your work).
