Many companies use private APIs to manage their A/B tests of experimental products and approaches; by grabbing the calls that mobile apps make to these APIs, Jon Luca was able to figure out all kinds of sensitive information about companies' future plans, from the way Lyft steers customers towards credit cards that are cheaper to process and its use of "Tactical Price Adjustments" to fight customers who price-compare with Uber; to Airbnb's future China plans; to Pintrest's gendered content differentiation and so on.
There's lots more: Amazon's upcoming augmented reality offerings; to Tinder's incomplete erasure of a now-deprecated feature that let you view a prospect's Instagram.
Luca has promised a followup in the months to come.
Most companies aren’t obfuscating or minimizing their experiment names, which leads to information leakage. This could prove dangerous in the future - if a company is slowly rolling out a new feature, it could give their competitors an advantage.
This is a common occurrence in the industry - nearly every company is siloing off their growth engineering department, which leads to siloed off experiment routes. This in turn makes it almost trivial to figure out what they’re working on, and make educated guesses at the 6 month roadmap of most tech services.
Some future companies I’d like to try and check out are Snapchat, Ebay, all the Google products and services, and LinkedIn.
There’s a lot more apps and services that this methodology works with. Feel free to reach out if you’re interested in finding any given companies experimentation campaigns.

Documents on an unprotected, network-connected drive owned by an employee of Nokia shed light on the inner workings of Russia’s networked surveillance system known as SORM (Russian: COPM).
Thomas Piketty, the French economist behind 2014's game-changing Capital in the 21st Century, has a new book, Capital and Ideology (out in France now, coming in English in 2020), which uses the same long-run economic series that Capital 21C benefited from to understand the relationship between wealth and ideology. Central to Piketty's thesis: that it's […]
The real estate bubble is in trouble: London's luxury housing market has been in freefall for years, and New York's retail vacancy has been soaring, even as global super-luxe housing is also tanking.
If you’ve worked in any high-performing engineering lab, you already know about MATLAB. This computing environment and the language that powers it is perfectly suited to science and math, with an interface that makes it easy to express and visualize complex algorithms – not to mention an infrastructure that lets it easily work with other […]
Studies have shown cannabidiol (more popularly known as CBD) to be effective in two main areas: Pain relief and stress relief. Both of those make the non-psychoactive, cannabis-derived compound a natural for topical creams. There’s no shortage of CBD products out there, but here’s eight of our favorites, all specifically designed for dermatological use – […]
