An in depth playbook on Retention

Hey there! Haven’t sent an email in a while as I’ve been super busy with June

I just published an in depth playbook on how to understand, measure, and improve your product’s retention

If you’re into building products and you like my writing I promise you’ll learn something useful from this!

Here is a link:

Let me know what you think about it


We closed our seed round and some interesting links

It’s June! Summer is coming and Paris is opening up.

This month was intense:

  • Got my first jab of the vaccine

  • We announced a $1.85M seed round led by Point Nine

  • Caught up and partied in Paris with my best friend from middle school (big hug Pietro)

  • Wrote a blog post on why throughput is the only thing that matters to me

  • We closed two key engineering hires that have the right skills and energy we want to be surrounded with every day

  • I set up my home office with a better camera, microphone, and ergonomics

  • Worked on a big datastore migration for June to keep scaling with our users

  • Started getting fit again - exercising and always doing 3 meals a day again

Other than this I had time to explore interesting ideas and books

Steward Brand & the Whole Earth Catalog

I think in the office at Stripe press they have a picture of me as the ideal customer persona.

After seeing that they made a documentary on Steward Brand (btw if you work at Stripe send me a link to watch this 🙏). I got into the rabbit hole of the Whole Earth Catalog.

I have a copy of the “Last Whole Earth Catalog” and I love skimming through it as it feels like reading a medieval alchemy handbook, with descriptions of how to make random interesting objects

Wong Kar-wai’s aesthetic

My roommate is into these Wong Kar-wai movies and I find the scenes to be extremely fascinating

I find this Hong Kong cyberpunk aesthetic extremely charming, the storylines are awful but the way the images and scenes are built is mind blowing

Zenly is so cool - Buying Snap stock

Over the last month after hanging out with a friend that works at Zenly/Snap and after seeing the Snap partners summit I’ve become quite obsessed with the user experience of their apps and their vision for the future

Over the next months, I hope I’ll be walking around looking goofy wearing these

Innovation in user experience seems to flow from games to consumer apps and then into business software.

Building June we’re trying to turn getting insights from data into something playful and approachable. I want to take inspiration from Super Mario and social apps in the way we build our onboarding.

If we design a user journey that doesn’t require talking to a human or reading a manual to figure things out, we will win

That’s it for this month! Reply with interesting books and ideas you’ve been fascinated with in the last month


I’m back writing as in the last month I’ve had more time to read! Switching up the format and just recommending some links this month.

Here are some things I liked this month:

Energy transitions are a lot slower than you think

The Principle of Normality: A normal person says what others say, but does what others do. - Being normal

The future of ideology - skip the first 30% of the video

This video creates a good picture of the current ideological state of most of the world. Predictions made taking the past as an example of how things will almost never work, but what the guy says about the present and past is interesting

Dedication to individual accomplishment: Teams were almost considered socialist institutions. Most great innovations at PayPal were driven by one person who then conscripted others to support, adopt, implement the new idea. If you identified the 8-12 most critical innovations at PayPal (or perhaps even the most important 25), almost every one had a single person inspire it (and often it drive it to implementation). As a result, David enforced an anti-meeting culture where any meeting that included more than 3-4 people was deemed suspect and subject to immediate adjournment if he gauged it inefficient. Our annual review forms in 2002 included a direction to rate the employee on "avoids imposing on others’ time, e.g. scheduling unnecessary meetings." (by Keith Rabois, former Executive Vice President of Paypal)

PS: I’m back in Paris now for the next few months, happy to meet up if you’re here!

Work with me

I haven’t sent my monthly update last month. I’ve been working hard on June at that was and is taking all of my energy

I’m now hiring someone as a founding engineer to join me, Vinayak and Enzo building some kick-ass software.

I wrote two pieces of content over the last two months.

The first one is about an open engineering challenge we’re facing around having mutable vs immutable data

The second one is a guide on how startups should do product analytics, you can find it here

Looking forward to next month!


Come and help! I just launched June

It's live now on Product Hunt

Hey - I’ve got some good news. After our launch on Hacker News last week this week we’re live on Product Hunt.

Also if you’re in a Slack or a Discord where people share new products or industry news I’d be super grateful if you could share a link to our launch there

PS: I’ll share the monthly update at the end of the week
