You cannot improve what you do not measure. But for early-stage startups, paying for analytics tools is hard to justify when you have 12 users and a $200/month total budget.
The good news: in 2026, the best analytics tools have surprisingly generous free tiers. Many of them give startups everything they need to make data-driven decisions without spending a dollar.
