🌎 Welcome back to the CleanTechies PodLetter, founder edition.

Today, we are talking to Leise Sandeman from Pathways

Shoutout to Leise and the Pathways team for their recent fundraise 🚀🚀🚀 You can find her announcement of it here and the Axios article here!

We had the chance to talk about this off the record and are so happy to be putting this episode out at the time of their announcement 🎉

In this episode, we discuss…

  • How Pathways develops software for material manufacturers' environmental impact analysis

  • What an Environmental Product Declarations (EPD) is and how it aids in carbon reduction

  • Why success in startups requires relationship building, understanding perspectives, and audacious goals

Ask yourself this: is the content we put out valuable enough to you that you’d be willing to buy us a latte 🍵 once a month?

The Guest: Leise Sandeman

  • Leise started her career as a consultant at McKinsey and a project manager, exercising skills in information synthesis and team management that became crucial in how she handles her co-founder relationship

  • She started Pathways in grad school at Harvard, finding it the optimal time and place to launch a startup in the built environment

The Startup: Pathways

Materials, Manufacturing, Construction, Software

One-liner: Pathways is a platform for manufacturers that simplifies the creation of product life cycle analyses.

Pathways is developing AI-enabled technologies that integrate across operations, ingesting supplier data and giving manufacturers insight into the environmental emissions impact. They’re like the environmental nutrition facts for materials. But instead of calories and carbs, we measure chemicals and carbon.

This enables product decarbonization through emission hot spots, material life-time trade-offs and creation of environmental product declarations.
