When Google Optimize shut down in 2023, marketing teams scrambled for alternatives to the split-testing tool. Mida.so emerged to fill that gap. Founders Donald Ng and Li Rou Chua initially focused on easy test setup. A visit to a UK customer changed their perspective entirely.
The client explained that engineering backlogs delayed tests by months. This insight revealed that building variants was the actual bottleneck, so the founders pivoted to solve variant creation rather than just test management.
😟 Problem
Marketing teams often struggle to run A/B tests despite knowing their value. Developers must build every variant, causing experiments to sit in engineering backlogs for months. There are other issues:
- Most teams only launch 1–2 tests per month.
- High-velocity testing (15+ per month) is required for significant growth.
- Lean SaaS and ecommerce teams feel this pain most acutely.
💡 Solution
Mida uses generative AI to remove the developer requirement from experimentation. Marketers describe changes via a chat interface to generate production-ready variants. On the platform:
- Users issue commands like “make the nav bar sticky” or “add a discount badge.”
- The system builds the variant immediately for review and launch.
- This process replaces days of engineering work with minutes of interaction.
