As CTO and co-founder of Zealot, an AI-powered customer activation platform, Brandon Jakobson often sweats the details of product improvement. He’s constantly thinking about how the team can scale faster, ship more, and do more for users.
“I’m deeply passionate about it and I have a lot of ideas for the future,” says Brandon. “How can we make sure our systems are always up, and that we’re always getting faster? Truthfully, it keeps me awake at night.”
Knowing product analytics are essential for making such decisions, Brandon initially installed both Amplitude and PostHog side-by-side. PostHog had initially been personally recommended, whereas Amplitude was the traditional tool for many of the large enterprises that use Zealot’s software.
“Our customers are enterprises and they all use Amplitude, but I personally just love PostHog,” says Brandon. “One big difference is that when I’ve needed help with PostHog I get through to people like David — the actual engineers building the tools, not a customer support agent.”
“Plus, Amplitude was very clunky and it was missing data points. We would notice it was having a hard time capturing some things when we used it in parallel with PostHog. Using PostHog just became second nature and we felt it was definitely exceeding Amplitude.”
As a result the team quickly doubled down on PostHog and Brandon immediately started inviting more of the team to use it.
