Founded by Sherwin Lai & Sina Mollaei

Sherwin Lai and Sina Mollaei are Stanford CS grads who both experienced the consumer insights problem firsthand. As an ML engineer at YouTube, Sherwin saw how difficult it was to collect and analyze community feedback at scale. So he spearheaded a viewer insights platform that analyzed satisfaction data to improve how posts and comments are ranked. Sina was an AI researcher at Harvard Medical School and the Stanford School of Medicine, where he extracted insights from complex, unstructured data. Together, they realized they could solve the outdated market research workflow that plagues consumer brands.

Problem

The current customer sentiment analytics workflow is broken. Businesses that want to understand what their customers think have to:

❌ Hire expensive consultants to write surveys
❌ Spend thousands of $$$ on vendors to deploy each survey
❌ Comb through hundreds of online conversations by hand to see what people are saying
❌ Manually analyze and compile data into reports

Solution

Lemma does all that in minutes by:

✅ Scouring the internet to find and aggregate what people are actually saying
✅ Automating survey writing and data collection to supplement the qualitative insights
✅ Crunching the numbers and drafting a memo or report in minutes, cutting through days of manual work at a time
