The Supercritical Mission
Supercritical is the leading carbon removal marketplace: 1 in 5 corporate carbon removal buyers are customers. The company builds the commercial architecture that turns carbon removal pledges into delivered tonnes, sourcing, creating, and guaranteeing permanent supply for corporate buyers running multi-year procurement programs. It has facilitated nearly 2 million tonnes of carbon removal for 200+ buyers and tracks 600+ suppliers across roughly 80% of the global permanent CDR market.
Quality is the strategy. Supercritical’s independent science team vets every project across 118 data points and rejects 88% of what it assesses, and the same scientists help set the standards buyers will be measured against, including on SBTi’s Expert Working Group for carbon removals. When the right supply does not exist, Supercritical creates it: Liferaft was co-designed from the ground up for Microsoft’s 1-million-tonne offtake, the largest biochar offtake in US history, signed in under 18 months. Every contract carries three layers of delivery protection. More than 300,000 tonnes have already been delivered and retired, with zero missed retirements to date.
The mission has never been more explicit. The UN now says the world is set to overshoot 1.5°C, and that carbon removal, alongside deep emissions cuts, is essential to coming back. The requirement is roughly 10 billion tonnes a year by 2050; all the permanent removal ever delivered adds up to less than a single day of that. Supercritical exists to close the gap. Its mission: scale carbon removal to gigatonnes by building the connective infrastructure for the market. Founded in 2021 by Michelle You and Aaron Randall, the team behind Songkick, Supercritical is backed by Lightspeed Venture Partners, MMC Ventures, RTP Global, GreenCode Ventures, and LocalGlobe.

Our values
We have set ourselves the mission of leading the carbon removal market to 14,000x its current size by 2050. In order to do that we need brave adventurers that think huge and deliver at speed. We call this the 14,000x mindset. The key components of the 14,000x mindset are:

- ☀️ Radiate positive energy: We come to problems with energy and passion. We nurture new ideas and engage positively in testing them. We inspire our colleagues to go further and are resilient to set backs. We recharge by taking time off. We are here for a great day, not a long day.
- 📣 Communicate proactively: We communicate simply and directly. We broadcast updates, insights and lessons learnt, especially when things haven’t gone to plan. We give as much context as possible so our teammates can make great decisions.
