Startup insights
Value proposition

Otter turns A/B testing into a decision anyone can make — set up experiments visually, and get a plain-English verdict on which version actually earns more revenue.

Problem solved

Most testing tools hand you dashboards of statistics and leave you to interpret them. Otter tells you which variant won, what it's worth in revenue, and when it's safe to call it.
