Kimberly Baker

Kimberly Baker did not set out to fund climate startups. She grew up in a small coastal town in Rhode Island, studied engineering as an undergrad (her own telling is that the college counselor said she was good at math, so she did it), then drove across the country and took the most traditional job the sector offers, a consulting engineer working on remediation, which is the cleanup of land and water that is already polluted, often right next to a refinery. She still remembers the smell. And that work taught her the thing that reshaped everything after it: she would rather attack the big problems at the source than spend a career cleaning up the aftermath.

Kimberly Baker went back to school for an MBA in sustainable management, co-founded an early-stage industrial wastewater company, then joined a growth-stage drinking-water company and stayed about a year after it was acquired. So by the time she joined Elemental in 2018, she had sat in nearly every seat a water company can offer, engineer, founder, product lead, which is exactly the background that makes an accelerator's diligence sharp rather than naive. At Elemental she rose to run the water and circular-economy portfolio, screening founders through a three-round process and backing the ones who had a working prototype and real, measurable impact.

Kimberly Baker spent those years inside Elemental (Elemental Excelerator at the time, now Elemental Impact), a nonprofit climate accelerator founded in Honolulu in 2012 that hands early-stage climate and water companies catalytic capital and hands-on help to close the gap between a promising prototype and commercial scale. The episode title gives the headline number: the portfolio she helped steward triggered about $1.5 billion in new follow-on funding. In her own figures from early 2021, that book had already produced 13 acquisitions and one IPO, with 70% of companies going on to raise more money and only ten businesses lost across the entire portfolio.

Kimberly Baker takes a deliberately broad view of water, with no single bet on wastewater, drinking water or stormwater, paired with what she calls a place-based approach, rooted in the communities a technology is actually meant to serve. Her contrarian read is worth sitting with: while the rest of the sector talks about digital, AI and machine learning, she thinks the overlooked opportunity is the workforce, software that helps utilities and industrial water operators engage their employees, keep them safe, and hold on to them. And she frames her own job with real humility, telling me she is not the one with all the answers, that the accelerator's role is to surface the hard conversations and let founders find their own way through them.

Kimberly Baker is also a mom, and the proudest moment she shared on the show was her three-year-old, mid-pandemic, looking up from the television and asking, in her words, whether renewable is better. It is the kind of detail that tells you why she does the work, because the goal underneath the cap tables and the diligence rounds is fairly simple: that the next generation grows up taking clean energy and clean water as the obvious default rather than the exception.

“We've had 13 acquisitions and 1 IPO in our portfolio. We've only got 10 companies that are out of business in the entire portfolio, and 70% have gone on to raise additional funding.”

Kimberly Baker has since stepped away from Elemental and now sits on boards as an independent director, but the through-line holds: an engineer who learned the water sector from the inside, then spent her years at the accelerator making sure good technology actually reached the people who need it.
