About Lily AI:

Lily AI is a female-founded retail technology company dedicated to empowering retailers and brands by bridging the gap between brand-speak and customer-speak. Combining visual AI with enterprise-grade product attribution capabilities, Lily enhances customer shopping experiences by injecting consumer-centric language throughout the retail technology ecosystem, from site search and demand forecasting to SEO, retail media and beyond.

Specifically, Lily AI allows major retailers and brands to:

  • Improve the overall digital shopping experience, nurturing more engaged shoppers with higher eCommerce site conversion
  • Achieve 8-9 digit revenue lifts
  • Assign 10x more attributes for each product - from fit to style, from embellishments to occasion, seasonal and even micro-trends
  • Better understand customer shopping dynamics to inform future product development and assortments as well as improve forecasting


At Lily AI, we’re serious when we say that we are committed to creating an amazing culture where each and every team member can thrive. First and foremost, we’re not just colleagues; we’re like a family - known for being caring, encouraging and always going the extra mile to help each other out. It’s startup world and as those who have worked for a startup know, every day is vastly different than the day before and as such, we place premium value on high empathy - both with our team members and our clients, fostering an environment where we listen and support each other through challenges and triumphs alike.

And speaking of the startup world, every single employee, without exception, is offered stock options because we believe everyone should be rewarded for their hard work and drive for results.

And speaking of results, earlier this Spring, we were honored to be included in the prestigious Top 100 Retail Tech Companies list released by CB Insights. While that was a proud moment, our proudest achievement is the top ratings we consistently receive from our own employees as reflected on Comparably.
