How to not break up with your cofounder

1. You need to be equal partners

Tim (my cofounder and co-CEO) and I started with quite asymmetric experience.

I had previously been a VP of sales, responsible for sales, support, and account management. Tim was an insanely talented, 23-year-old engineer, and was much earlier in his career I m nearly 10 years older.

I’ve been using PostHog for about 3 months, and it has quickly become one of my favorite tools for understanding and improving our product. What I like: The web and product analytics dashboards are intuitive and provide deep insights into user behavior. Session replay has been incredibly helpful in identifying UX issues and understanding how real users interact with features. The feature flag functionality makes controlled rollouts super easy — no need for extra infrastructure or tools. I love that everything (analytics, replays, feature flags, and experiments) is built into one platform, which saves a ton of time switching between tools.

I think they have a great platform and right abstractions of events, actions, etc. that's getting more feature rich every week and it's great that since it's still a somewhat young project they are really open to feedback and suggestions and actually are able to continually deliver improvement in the product on an ongoing basis which is pretty delightful as an end user. Last thing that's a biggie for me too is the great culture and openness of the project and team - it's just been so easy and painless to work with them. Even if we do run into some sort of issue or feature we might want to see in the product - its as simple as a feature request in the GH repo and can have full transparency and tracking on it from there as well as see if other users feel the same way. So this lets you feel like you can easily be part of the community around PostHog and help to continually make it better.

PostHog

to build Acedit

•8 reviews

PostHog has been absolutely instrumental in the development and refinement of Acedit. As an open-source product OS, it provides us with deep insights into how job seekers are actually using our AI interview coach. Understanding user journeys through its powerful analytics and session replay tools allows us to pinpoint exactly where users get the most value – whether it's prepping with tailored Q&A, practicing in mock interviews, or getting live suggestions – and identify areas where we can make the experience even smoother and more effective. Furthermore, PostHog's feature flags and experimentation capabilities are crucial for us. They enable our team to safely test and roll out new enhancements, like improvements to our real-time suggestion algorithms or UI adjustments, ensuring we continuously iterate based on real data, not just guesswork. This helps us build a more robust and user-centric tool, ultimately helping more people feel confident and prepared to ace their interviews. We genuinely couldn't build Acedit as effectively without the clarity PostHog provides.
