Julia Kumari Drapkin is the CEO and founder of ISeeChange, a data platform that combines resident-generated insights with AI to address climate adaptation challenges. Julia’s background as a climate science reporter, covering disasters like Hurricane Katrina, inspired her to bridge the gap between people’s lived experiences and actionable climate solutions. Her expertise in storytelling and data-driven insights shapes ISeeChange's people-first approach to building climate resilience.
ISeeChange leverages ground-truth data—stories, photos, and observations—from residents and combines it with sensor, satellite, and proprietary AI models. The platform delivers actionable insights to cities, counties, and utilities, enabling them to prioritize real-time responses and long-term infrastructure design to adapt to 21st-century climate risks. By creating a feedback loop between communities and decision-makers, ISeeChange helps build trust, improve climate outcomes, and unlock the value of previously siloed data.
In this episode, Julia shares insights on:
Ground-Truth Data Integration combining resident observations with existing satellite and sensor data, delivering more granular and actionable insights for managing floods, heat waves, and infrastructure failuresAdaptation Over Politics, evident by how they are growing fastest in Republican-led states, showing that climate impacts are bipartisan and adaptation solutions resonate when framed around local needs like infrastructure protection and economic resilienceAI-Driven data processing, enabling faster prioritization of critical tasks while transforming anecdotal community feedback into validated, actionable intelligence for utilities and governmentsEnjoy!

On today’s episode, Rob van Straten, the CEO of Skytree captures our attention with his deep wisdom on how to scale a successful carbon capture technology company.Why you should trust him? He brings a long career of experience building and scaling companies that he parlayed into Skytree where they are currently crushing it with their modular, mass-production capable carbon capture system.
Spoiler alert, you can’t do this successfully if you’re doing it on a project basis - you need to do it with a modular system that you can mass produce (it allows for faster iteration of the design).
Learn:
**How they build their team culture and value young talents
**How Oil & Gas has been catching and releasing carbon for years and how Skytree is now actually solving this problem — also related, why their largest investor is the largest owner/operator of greenhouses in the Netherlands
**Why you MUST set out to achieve scale from day one.

Amy Duffuor is a co-founder and General Partner at Azolla Ventures and Managing Director at Prime Impact Fund, Azolla's predecessor vehicle. She has a diverse background that spans immigration research, management consulting, impact investing, and renewables investment banking. Amy began her career studying marginalized West African migrants and later pursued an MPhil in Migration Studies at Oxford University. Transitioning into management consulting, she worked on supply chain and procurement projects in London and Southeast Asia, where she developed a passion for climate change solutions. Her experience running venture accelerator programs in Southeast Asia for impact-driven startups inspired her to focus on early-stage climate tech investing. Prior to Azolla, Amy worked at Bank of America as a renewables investment banker, contributing to projects like the IPO of Sunnova, a leading residential solar company.
Azolla Ventures is a venture capital firm that focuses on early-stage investments in climate technology startups. Their investment strategy emphasizes three key criteria: Impact, Additionality and Commercial Potential. In July 2023, Azolla Ventures announced the final close of their fund at $239 million. This fund blends catalytic, charitable capital with impact-aligned, market-rate capital to drive investment into solutions with deep potential for climate impact that are systemically overlooked by conventional financiers. Amy has even constructed a microcosm of LP signals that they use to understand where investing gaps in the ClimateTech funding ecosystem lie.
In this episode, Amy shares insights on:

Today we are joined by Duncan Logan, CEO & Co-Founder of 9Zero. A community platform to bring climate professionals together in person and online so we can work together to solve the climate crisis.
Duncan previously founded RocketSpace where he saw many tech startups that would go on to become unicorns. Companies like Uber, FlexPort, and Spotify. Having this experience made him realize the importance of creating a hub for people to collaborate and bump into each other.
They are extending this even further by building these hubs in all major climate cities because unlike the 2000’s tech boom, there is no one silicon valley for climate. We need to connect NY, DC, Boston, Houston, London, Berlin, SF, Seattle, and beyond.
Duncan brings a lot of experience and some great stories (like the time he met Elon).
Enjoy!

Today, we are speaking with Liz Dennett, the CEO and Founder of Endolith.
Endolith recently spun out of Cemvita to form its own independent company. (Ep #200 with Moji from Cemvita)
By 2050, we will need more copper than in the history of mankind due to the electrification of industry and developing countries. If we don’t solve this, it could lead to geopolitical conflicts.
Their tech uses microbes to eat crushed rocks and poop out copper (I did say explain it to me like I’m 5). They add this to existing mining operations to increase output by ~10%.
This helps us get closer to solving copper demand.
In today’s conversation, we cover
**Copper in electrification
**Her journey to CEO of Endolith
**Why copper could be the thing wars are fought over
**The innovation behind microbial mining
**The balance between generating hype and focusing on scientific advancements

And... don't forget to fill out the post climate week survey! 📝
What events we liked — Third Sphere, Political Risk Event, Climate Capital Summit, New Climate Futures The events we didn’t like — VC hangouts & loud bar meetups Our biggest takeaways — There needs to be better collaboration across events; and the UNGA & NYCW are competing for the best climate talentOur biggest gripes — Too much posturing and getting stuck in echo chambers; too much noise — not enough signal What we are going to do differently next year — hosting more of our own events / attending fewer ones & finding places where the real debates are happening Our hot takes 🔥:FOAK financing isn’t realDealflow isn’t an alpha for VCs anymoreStartups need to pursue generating PE-quality returns to succeed
NYCW 2024 was a DOOZY…filled with plenty of good and crazy times that we equally don’t really remember. It went by in a blur, but so much happened in the week that we need to break it down with all you CleanTechies out there.
