We are rapidly designing and building a pulsed magnetic fusion system to achieve net facility gain (more fusion energy output than stored energy input). In parallel, we are developing the key components required to build affordable fusion systems.
Our plans are ambitious. We have raised over $900M so far from incredible investors, resourcing us to deliver on these plans. We are bringing together the best scientists, engineers, and operators from the fusion community, hard tech industry, and other sectors.

There’s huge potential in the new chapter of AI-powered customer service. But it will only be captured by companies that can shake up the industry models that hold back innovation.
We’re a group of founders who have worked in customer experience for years. Our tech and our people have served billions of customers and provided exceptional service across the world.
Crescendo is our vision for finally changing what’s held us back before.
We’re combining the most advanced AI technology with the best human agents to provide a blended experience. We’re eliminating the separation between the contact center and the technology provider. With everything orchestrated together, we can dramatically accelerate improvements to agent and customer experience.
That means customer service that’s more in sync, easier to manage, and more tightly integrated than ever before.
And our customers will only pay for positive outcomes. It’s a brilliant harmony of AI and CX.

Charm Industrial is working to return the atmosphere to 280 ppm CO₂. We design, build and operate a fleet of mobile fast pyrolyzers that convert ag and forest biomass residues into bio-oil for use in carbon removal and direct-reduced-iron steelmaking.
In 2020 our Chief Scientist and co-founder Shaun Meehan had two breakthroughs (bio-oil intermediate and bio-oil sequestration) that kickstarted the company. Within 10 months we completed our first carbon removal injection and in 2021 we completed more than 5,000 tons of CO₂e removal for customers like Stripe, Shopify and Microsoft.

Homeward is rearchitecting the delivery of health and care for rural Americans by connecting payers, providers, and community organizations through partnership. By taking full financial accountability for clinical outcomes and the total cost of care across rural counties, Homeward aligns incentives and strengthens local healthcare ecosystems. The Homeward Navigation™ platform uses advanced analytics to connect members to the right care and local resources that address social determinants of health and improve holistic health outcomes.
