In episode 5 of the Scaling Green Tech podcast, Katherine Keddie speaks with Rhea Dabriwala and Naveen Shivalingam, the co-founders of GroundUp, a pioneering startup transforming India’s agricultural waste into high-impact biochar. They unpack how GroundUp is building a new generation of industrial-scale biochar hubs that don’t just remove carbon from the atmosphere, but also regenerate soil, boost farmer livelihoods, and unlock circular supply chains.

They break down the science behind biochar, the future of carbon markets, and the scale of what’s possible. They also explore what it takes to raise a $5M seed round, build trust in high-integrity carbon credits, and stay obsessed through the hardest parts of the founder journey.

In episode 2 of the Scaling Green-Tech podcast, Adopter co-founders Matt Jaworski and Katherine Keddie explore one of the biggest risks facing early-stage green-tech companies: greenwashing. As regulation tightens and investor scrutiny grows, being vague or overly optimistic about your impact can undermine your credibility and your ability to scale.

They break down the six types of greenwashing every climate tech company should know, from overhyping one green initiative (greenlighting) to avoiding talking about impact altogether (greenhushing). Along the way, they explain why being evidence-backed is now non-negotiable and how early choices around messaging and carbon accounting can create risk or resilience down the line.

Matt and Kat also share real-world examples of impact-washing, offer tips on how to communicate your sustainability story with clarity and confidence, and explain how to build trust with investors, partners, and customers from day one. If you’re building a green-tech business and want to avoid greenwashing without going silent, this one’s for you.

In episode 1 of the Scaling Green-Tech podcast, Adopter co-founders Matt Jaworski and Katherine Keddie dive into why websites matter, especially for early-stage climate founders. Even if you’re still at the idea stage, having a simple, functional, and up-to-date site can make all the difference when it comes to credibility, traction, and first impressions with investors or partners.

They unpack five common mistakes they see all the time: leaving your website to gather dust, using vague or overly technical language, getting locked into expensive suppliers, choosing platforms that don’t grow with you, and skipping real-world images or examples that show your solution actually exists.

Throughout the episode, Matt and Katherine share tips on how to avoid these traps and explain why your website isn’t just a box to tick, it’s a key part of how your business shows up in the world. If you’re wondering where to start with your green-tech website, this one’s for you.
