So you want to be a product manager? Make yourself the product.

Founder and CEO of Product School, Carlos Gonzalez de Villaumbrosia shares the fundamental rubric for next-generation PMs: what it takes to become one and the table stakes for your first day on the job. On the edge of North Beach in San Francisco, there’s a basement below the pixel-pushers at Imgur. Some (me) may argue this is the real OG of the city: back in 1851, this was the the original Ghiradelli chocolate factory. Today, like so many hip places in San Francisco with its exposed brick still intact, this spot is a coworking haven for entrepreneurial meetups and early stage startups. It’s also where Carlos Gonzalez de Villaumbrosia, founder and chief executive officer of Product School , teaches the next generation of product managers. While The Lean Startup , The Hard Thing About Hard Things , and Hooked should be in every aspiring PM’s Kindle, Carlos is one of the few to...

Why most A/B tests give you bullshit results

By now, anyone in product or marketing knows what A/B testing is. What we don’t know, or at least won’t admit, is that too many A/B tests yield nothing. Too often they measure meaningless variants, produce inconclusive results, and nothing comes from them. Of course, some A/B tests yield real, meaningful, actionable results. Those are the ones you hear about. We've all seen the articles. Company X increases conversions 38% with this simple trick. Hell, I've written some of them. But those success stories have hidden the grey underbelly of testing and experimentation. AppSumo revealed that only 1 out of 8 tests produce results . Kaiser Fung estimates that 80 to 90 percent of the A/B tests he’s run yield statistically insignificant results . Yet many new testers walk into A/B testing thinking it'll be quick and easy to get results. After running a handful of simple tests, ...

Downtime: Ingestion API post-mortem

On January 20th, 4:05pm PST, Mixpanel’s ingestion API was intermittently unavailable until approximately 8:55pm PST. This incident was caused by two main factors: insufficient capacity in our backend queuing system and a bug in our Android SDK that produced a thundering herd . At 2:30pm, we rerouted traffic away from one of our datacenters due to planned network maintenance, placing double the load on our Washington, DC datacenter. At 4:00pm, a 10X spike in ingestion traffic occurred. Combined with the additional load from the maintenance, we started queuing data. We queued enough data to cause our queue servers to become disk IO bound. This lowered the enqueue throughput, causing some API requests to time out. Due to a bug, our Android client library responded to these timeouts by retrying every second instead of backing off. This triggered a thundering herd. The influx of retr...

How Breather built a network of spaces and succeeded where so many startups fail

Supplying peace and quiet while solving the on-demand economy. “Acquire users.” That's the common wisdom for consumer-facing startups. The more users, the better. Not unexpectedly, many of these companies focus all of their energy on driving demand, and often it makes sense. Just look at the tech giants that have built their businesses on a foundation of millions and millions of users, often acquiring masses before they even knew what their businesses really was. And if you're Facebook or LinkedIn, it makes sense. These companies aren't worried about supply. What are they going to do, run out of LinkedIn? (Ignore the dirty looks Ops folks are sending my way.) In fact, because of demand-side economies of scale and the network effect , LinkedIn's product actually gets better with more users. But there's a new breed of startups playing a different – and often lucrative – game. T...

A guide towards App Store Optimization

Let’s face it, getting your application discovered in the App Store or Google Play is a huge challenge but if you find a way to crack the algorithm, the payoff is huge! There are more than 1.5 million applications on the Apple App Store that have been downloaded more than 100 billion times. With the average number of downloads an app gets being around 62,000, App Store Optimization ends up being an important technique that can push you way past the average. What is App Store Optimization? App Store Optimization is a technique app makers use to improve the visibility of a mobile app in an app store. It’s similar to search engine optimization (SEO) for websites but optimizes for discoverability for a mobile app. The basic techniques of ASO encompass doing good keyword research, improving your app description, utilizing high quality screenshots, doing competitive research, and...

Why QuizUp turned the fastest-growing game in history into a social platform

Two years ago, QuizUp became the fastest growing game in the history of the App Store. But to stay relevant and to maintain its users, they knew it had to become more. With data-driven development, QuizUp has grown into an app that brings its users back time and time again, transforming from a trivia game into a social platform. Every week, somewhere in the ballpark of 15 thousand apps are submitted to the iOS App Store. About a quarter of those are games. A quick glance at the Featured screen shows a "Best New Games" list with a couple dozen games released in the past week or so. They're from names as big as Lego, and as small as Futureplay, a five-person shop out of Helsinki releasing their first game. It's a highly competitive landscape. And each can only dream of the success that Plain Vanilla Games had in the first week with QuizUp: over a million downloads. Five months after ...

Demystifying Predictive Analytics for Mobile and Web Apps

Predictive analytics is unfathomable to many of us. Terms like artificial intelligence, neural networks and deep learning just deepen the mystery. Yet predictive tools are already ubiquitous. Not in self-driving cars, or robots that look like humans. Rather, on your phone. Spotify looks at your past listening habits, and that of people who like similar music, and recommends new tracks to listen to. Youtube does the same with videos. Your email service predicts whether a mail message sent to you is spam by analyzing past emails sent to you and others. Siri and Google Now use predictive technology to understand your voice, and offer answers to your questions. Predictive analytics is the practice of using advanced statistics and historical data to predict future outcomes. For the most part, the use of predictive analytics in business is still shrouded in mystery and the domain of ...
