Amplitude is an incredibly powerful tool, regardless of the size of your business. Their educational content is top notch too. I have attended a few of their webinars and found them very useful.
I think amplitude still the best data analytics now. But the problem, the price is high, only company with big capital that could afford it. Hopefully they will penetrate the product for middle to low business.
Amplitude has helped us refine our product and improve user engagement. I notice some slow performance with large-scale data processing, but overall, it’s a solid tool
