PostHog

““I realized that what you put into it is what you get out,” says Keith. “We started connecting customer break clauses with actual user activity, so we could see the link between usage and retention. PostHog became the cockpit from which we could see across the entire product and all our customers.””

“At SoundBoost we see a future where agents can work with you on your songs in real time," says Berkan. "PostHog is doing the same but for software development and, now that I know how this works, I'd definitely build it myself if PostHog didn't already exist.”

“At first I was scared, so I reviewed all the pull requests PostHog sent," he says. "But over time I learned to trust the data and Claude always told me it was a good PR that doesn't need any additions, so now I just merge them.”

“It's really easy to miss an action, or track it wrong, when you do it manually with code," he says. "After I discovered the MCP, I can even fix what's wrong in PostHog from my editor. It's the only way I develop new features with PostHog now.”

“We're a small team and we can't find everything that's going on across different browsers, operating systems, and device types. PostHog just finds it for us now.”

“PostHog's reports told us this was a bigger problem. It told us that conversions stopped, traffic was low, and we were losing our best funnel," Berkan recalls. "That was essential information for us and we immediately rolled back to the .ai domain, regaining all our traction from Google.”

“We're a small team, so every conversion matters to us. If we fix 10% here, 5% there? Those gains add up – and PostHog compiles that into a menu for me: fix these first, fix those later.”

“I've been founding companies for over 15 years and have always been a do-it-yourself guy for everything, including writing my own SQL to analyze data," says SoundBoost's founder, Berkan Cesur. "Then a friend at Automattic, Batuhan Icoz, suggested PostHog and for the first time I had a tool that anticipates what I want to do and takes me from analysis to an actual PR.”

“Instead of using 10 different data layers, data providers, and data collectors, you can just use PostHog.”

“I don't need to leave the PostHog ecosystem often. I get almost everything I need on PostHog, which makes it easy for me to make a lot of decisions very fast.”

“All decisions are driven by PostHog metrics. It gives us the direction when something is failing or impacts a specific event that really helps us a lot.”

“With so much left to build, it's great that PostHog is helping us not just gather better data, but also ship faster and increase stability so users can rely on us to track their health.”

“It's incredible that these agents can run autonomously to identify these things. You wake up in the morning and there are PRs waiting for you. All you have to do is review and merge.”

“PostHog already did what we were trying to build, so we didn't need to build our own version," he says. "It's so much nicer to have a system that's actually meant for it and integrated with all of the context seamlessly. Our merge rate for self-driving PRs is roughly 90% now that we use PostHog for self-driving.”

““We used to have a lot of Looker dashboards, and other tools,” says Sam. “Now, it’s just PostHog, BigQuery, and Stripe. For a business like ours where we have so many different types of users, PostHog is amazing. It reins in the chaos to have everything in one place. Otherwise it’s quite overwhelming to try and understand what’s working and what’s not.””

““Whenever we have a launch we’ll usually have a video that will go viral,” says Sam. “We’ll track that in PostHog using UTM parameters and we’ll monitor the traffic, sign-ups, and affiliate performance. I even use surveys to send a little pop-up to people and ask them to review us on G2.””

““We watch session replays a lot whenever we roll out a new feature,” says Sam. “We also love how easy it is to launch a survey and throw a Calendly link in there, so users can book their customer interviews. That info helps us keep improving, and sometimes we’ll send surveys to a specific cohort to get information on what specific types of customers think.””

““During testing we monitor weekly retention especially. We’ve got a mobile app in TestFlight at the moment and we’re tracking how it retains the users we invite to it. We want to make sure it’s not a leaky bucket before we invite all our web users to try it out.””

““We’ve tested changes as simple as changing the null state of a page to include more educational content, through to trialling entirely new onboarding flows,” explains Sam.”

““We use basically everything in PostHog to understand more about our users and to plan new launches,” says Sam Sklar, one of ElevenLabs’ growth engineers.”

“It’s exciting to be able to test these ideas so quickly, even when I’m spread thin. When I got that first boost to the newsletter signup conversion, I said to myself that running these experiments was my new job.”

“Very quickly I could see that people preferred the first version,” says Phil. “It said what the website does more concisely and wasn’t trying to be too clever. That’s an example of a good negative result, because it helps you avoid mistakes. Before I was A/B testing I would have probably just put this change blindly live, dropping my conversion rate in the process. That’s why I run these tests!”

“I found out about PostHog through a friend initially,” says Phil. “And I just knew from the content, the documentation, and the transparency that this was a good fit for me. I immediately became convinced that I needed to start A/B testing things with PostHog.”

“I started testing, then I started tracking events and building dashboards too. I realized PostHog is something I’ve been looking for for a while — somewhere I can have all the tools and analytics I need all in one place.”

“I'm so glad you guys don't price based on seats. As soon as I realized that, I invited my whole team.”
