Commonwealth Fusion Systems (CFS) is building compact high-temperature superconducting fusion reactors, with SPARC demonstrating net energy gain targeted for 2025 and commercial reactors by early 2030s. HQ: Devens, MA.
Commonwealth Fusion Systems (CFS) is a fusion energy company spun out of MIT's Plasma Science and Fusion Center in 2018, commercializing decades of fusion research through a proprietary approach using high-temperature superconducting (HTS) magnets. CFS's strategy centers on making fusion magnets much stronger than previously possible: HTS magnets can achieve field strengths of 20+ Tesla (more than twice conventional magnet capability), which allows fusion reactors to be dramatically smaller and cheaper — potentially shrinking a fusion power plant from stadium-scale to building-scale. The company's first demonstration reactor, SPARC, is under construction in Devens, Massachusetts.
US YC W24 interactive e-commerce email builder enabling in-email shopping (browse/buy) for Shopify merchants at 27% more revenue vs traditional emails; $700K seed competing with Klaviyo flows for AMP-powered in-inbox checkout conversion.
Zaymo is a United States-based interactive e-commerce email platform — backed by Y Combinator (W24) with $700,000 in seed funding from YC — providing Shopify merchants and e-commerce brands with an email builder that creates fully interactive emails where customers can browse product catalogs, select variants (size, color), add items to cart, and complete purchases directly within the email inbox without being redirected to the brand's website. Founded in 2022 and generating 27% more revenue than traditional email commerce approaches, Zaymo addresses the conversion friction of standard e-commerce emails where every product click requires a browser redirect that drops the majority of email recipients who were about to convert.
