Looking for Ideas for Impact Entrepreneurship

A developer, a product manager and a data analyst walk into a bar... All setup, no joke. Actually they're there looking for advice.

Suppose there are three co-founders looking for a problem to solve. Suppose we want to start a business that makes a positive impact on the world. Suppose we have expertise and experience in the following areas: Web development, applications of AI and ML, data science and analytics, product management, e-commerce, direct-to-consumer product development and sales, blockchain technologies, community engagement, personal development and leadership. Educational background from top-tier engineering school in automation, biotechnology, and business development.

I'm looking for ideas to fall in love with. If you have one you want to share, I would be incredibly grateful.
