This is so close to the truth it's scary -- Rubber Ducky Labs's name was inspired by the giant rubber ducky art exhibit that visited Pittsburgh in 2013, almost exactly a decade ago!

Personalization and recommender systems LFG! Think through how you can personalize every surface of your product to reflect your users' preferences, from copywriting to product recommendations.

The incredible @Alexandraj777 CEO of Rubber Ducky Labs (YC W23) back at CMU School of Computer Science Carnegie Mellon University for her 10th reunion during Spring Carnival visiting Women@SCS students in front of my old office in Gates! None of the undergrads here were born when I started Women@SCS 25 years ago!

At the last Heavybit summit, Stefan Krawczyk let me drag him into leading an MLOps session together. This snowballed into a longer conversation musing on the nature of MLOps over the last decade 👇

New post on Rubber Ducky Labs (YC W23): Alexandra Johnson and I have heard a lot of horror stories of ML and senior leaders completely talking past each other when it comes to metrics. To optimize on CLTV, stop trying to iterate on CLTV! Use tactical goals instead.
