Spell
Spell is a Byron Bay fashion label founded in 2009 by sisters Isabella Pennefather and Elizabeth Abegg. Beginning as a jewellery stall at Byron's artisan markets, it grew into a globally recognised 'elevated boho' womenswear brand known for hand-drawn signature prints, dreamy romantic silhouettes, and a large, loyal online community. The company - which retired its former name 'Spell & The Gypsy Collective' - is a certified B Corporation and carbon-neutral business that has moved much of its supply chain toward organic and recycled fibres.
Twisted X Global Brands
Twisted X Global Brands is a Decatur, Texas-based footwear company that designs and manufactures comfortable, handcrafted western, work, casual and outdoor shoes and boots for men, women and children. Known for its patented CellStretch comfort technology and its ecoTWX fabric made from recycled plastic bottles, Twisted X pairs all-day comfort with a sustainability mission that made it one of the first carbon-neutral footwear companies. Under CEO Prasad Reddy, the company turned around from near-bankruptcy in 2009 into a fast-growing brand family that includes Twisted X, Twisted X Work, Black Star Boots, CellSole and licensed Wrangler Footwear.
Cox Enterprises
Cox Enterprises is a privately held, family-owned conglomerate based in Atlanta, Georgia, that traces its roots to a single Ohio newspaper bought by James M. Cox in 1898. Over more than a century it grew into a roughly $23 billion-a-year business spanning broadband and cable (Cox Communications), automotive services and marketplaces (Cox Automotive, which owns Autotrader, Kelley Blue Book and Manheim), and media (Cox Media Group and Axios). Still controlled by the Cox family and led by fourth-generation CEO Alex Taylor, the company reinvests its cash into new bets such as greenhouse agriculture, advanced plastics recycling and healthcare, while pursuing an aggressive Cox Conserves goal to be carbon and water neutral by 2034.
Furno Materials
Furno Materials is a California cleantech company rebuilding how cement is made. Instead of the mile-long rotary kilns that make cement one of the dirtiest industries on earth - roughly 8% of global CO2 - Furno builds compact, modular vertical micro-kilns (the 'Furno Brick') that run at more than 80% thermal efficiency, roughly double a conventional plant. The kilns burn gas-based fuels, eliminate NOx and SOx emissions entirely, cut fossil-fuel emissions by at least 70%, and can reach zero emissions on hydrogen - all while producing standards-grade Ordinary Portland Cement at the point of demand.
Rosaluna Mezcal
Rosaluna is an all-natural, single-estate mezcal handmade in Santiago Matatlan, Oaxaca, by a family with more than six generations of agave-growing heritage. Made with only agave, water and a slow maturation that yields a sweeter, less smoky profile, the brand pairs Oaxacan craft with a design-forward identity built around the idea that 'Mezcal is Magic.' Certified organic, vegan, non-GMO and carbon neutral, Rosaluna became the first mezcal brand to earn the Distintivo Verde sustainability certification, and in 2025 raised Series A financing led by wine entrepreneur Sacha Lichine to scale distribution across the United States.
Solarbiotech
Solarbiotech is a U.S.-based synthetic biology and biomanufacturing company that helps companies move precision-fermentation products from lab bench to commercial scale. Built around a Norton, Virginia plant with fermentation capacity from 6L to 10,000L and a modular 'BioNodes' architecture, it offers end-to-end strain-to-shelf services - upstream fermentation, downstream processing, and commercial production - for food ingredients, nutraceuticals, cosmetics, enzymes, and industrial bioproducts. After a 2024 Chapter 11 restructuring, its assets were acquired by Pictor Biotech (led by ex-Novozymes executive Peter Rosholm) and unified in January 2025 with GPC Bio and Eleszto Genetika into a vertically integrated, 100+ person SynBio platform.
Blue Bottle Coffee
Blue Bottle Coffee is an Oakland-born specialty roaster and cafe chain that helped define the third-wave coffee movement. Founded in 2002 by clarinetist James Freeman, it built a reputation on freshly roasted single-origin beans, an obsessive 48-hour freshness rule, and a spare, Japanese-influenced cafe aesthetic. It now runs roughly 140 cafes across the US and Asia plus a sizable e-commerce and subscription business, and changed hands in 2026 when Centurium Capital agreed to buy its retail operations from Nestle.
Lime
Lime is the world's largest shared electric vehicle company, renting dockless e-scooters and e-bikes through a single app across more than 200 cities in nearly 30 countries. Founded in 2017 as LimeBike, it pitches micromobility as the practical alternative to short car trips: cheaper, electric, and carbon-free. After surviving a brutal industry shakeout, Lime has turned cash-flow positive and filed to go public on Nasdaq under the ticker LIME.
Verdigris
Verdigris is a Mountain View-based AI and IoT company that turns raw electrical data into actionable intelligence for data centers, commercial buildings, and industrial facilities. By clamping high-frequency sensors onto electrical circuits and running proprietary AI algorithms on the resulting waveform data, Verdigris gives facility operators real-time visibility into energy consumption, power quality, and equipment health - detecting failures before they happen, recovering stranded capacity, and driving 20-50% reductions in energy spend. Founded in 2011, the company serves Fortune 500 customers including T-Mobile, Verizon, and NVIDIA across 17 countries.
Mark Chung
Mark Chung is the co-founder and CEO of Verdigris Technologies, a Mountain View-based AI company that provides circuit-level electrical intelligence for mission-critical data centers and commercial buildings. A Stanford-trained electrical engineer who spent 15 years designing chips at AMD, PA Semi (Apple), and NetLogic (Broadcom), Chung founded Verdigris in 2011 after a $560 electricity bill sparked an obsession with making buildings as transparent as spreadsheets. Today, Verdigris monitors 2+ gigawatts of peak demand across 20 million square feet of facilities for clients like T-Mobile, Verizon, NVIDIA, and Google, using 8kHz waveform sensors that detect equipment failures up to 21 days before they cause outages.
