Why they matter

Founder-CEO of the most-differentiated industrial-wastewater technology. Credible disruptor in a slow-moving category.

Background

CEO and Co-Founder of Aquacycl (founded 2016). Developed the BioElectrochemical Treatment Technology (BETT®) at the J. Craig Venter Institute. Aquacycl commercializes modular plug-and-play industrial wastewater treatment using microbial fuel cells. 10x faster pollutant removal vs. conventional treatment, 50%+ reduction in greenhouse gas emissions, low or net-zero energy operation. Cartier Women's Initiative Fellow.

Notable deals

  • 2024
    Launched SulfideFix biological wastewater treatment to remove 99.9% of H2S from large-scale wastewater tanks.
  • 2024
    Deployed BETT systems with beverage-manufacturer customers proving operational success.

Call-prep brief

Background

Aquacycl's microbial-fuel-cell approach to industrial wastewater is a genuine technical novelty. Not an incremental improvement on activated sludge. Customer wins are concentrated in beverage / food-and-beverage manufacturing, where conventional treatment is expensive and energy-intensive.

What she cares about

  • Modular deployment economics. Aquacycl is sold as a unit, not a project.
  • Carbon-credit and ESG monetization of treatment-avoided emissions.
  • Industrial customer scale-up curve. Pilots → site-wide → multi-site.

Sensitivities

  • Earlier-stage company; founder-CEO will be evaluating investor partners carefully.

Questions to ask

  1. Which industrial verticals have the highest adoption-pull for modular wastewater?
  2. How does Aquacycl think about Series C / growth-equity financing vs. strategic partnership?
  3. What's the right reference comp: cambrian Innovation, Gradiant, or something different?
