# Dioxycle

> Dioxycle is a French-American climate-tech company building a low-temperature electrolyzer that turns waste CO2, water, and renewable electricity into sustainable ethylene - the world's most-used organic chemical - at a cost competitive with fossil-derived ethylene. Founded in 2021 by electrochemists Sarah Lamaison and David Wakerley, it aims to electrify chemical manufacturing and recycle industrial carbon emissions at gigaton scale.

- **Founded:** 2021
- **Headquarters:** Paris, France (with a San Francisco Bay Area site)
- **Founders:** Sarah Lamaison (Co-founder & CEO), David Wakerley (Co-founder & CTO)
- **Team size:** ~40+ employees across Paris and San Francisco, representing 15+ nationalities
- **Products:** CO2 Electrolyzer, Sustainable Ethylene
- **Notable:** Raised $17M Series A in 2023 co-led by Lowercarbon Capital and Breakthrough Energy Ventures Europe (later reported ~$40M raised to date)., Sarah Lamaison won the L'Oreal-UNESCO For Women in Science French Young Talent Award (2020) and was named a Breakthrough Energy Innovator Fellow (2021)., Moved from lab trials to a first prototype in 2022.

## Products & services

- **CO2 Electrolyzer** — A proprietary low-temperature electrolyzer that takes water, CO2, and renewable electricity as inputs and produces sustainable ethylene and oxygen. CO2 is distributed across stacked catalytic cores made from custom metal alloys to maximize reaction surface area and energy efficiency.
- **Sustainable Ethylene** — Carbon-recycled ethylene - the precursor to plastics, packaging, PVC pipes, textiles, and car interiors - produced at a cost competitive with fossil-based ethylene.

## Achievements

- Raised $17M Series A in 2023 co-led by Lowercarbon Capital and Breakthrough Energy Ventures Europe (later reported ~$40M raised to date).
- Sarah Lamaison won the L'Oreal-UNESCO For Women in Science French Young Talent Award (2020) and was named a Breakthrough Energy Innovator Fellow (2021).
- Moved from lab trials to a first prototype in 2022.
- Selected for the C2V Initiative's Carbontech Accelerator Program (2023).
- Built a 40+ person, 15+ nationality team across two continents.

## Latest updates

- **2023-07** — Closed $17M Series A led by Lowercarbon Capital and Breakthrough Energy Ventures Europe, with Gigascale Capital.
- **2024-08** — Listed EU funding support among its backers, alongside France 2030 program backing.
