Mafix develops a mineral conversion process that transforms abundant silicate rocks into silicon-based fertilizers that weather within a single growing season, releasing nutrients and removing CO2 as stable bicarbonate. The company is commercializing a first-generation climate-smart fertilizer and plans a commercial demonstration to produce 1,000 tons of product. Mafix’s manufacturing approach repurposes spare capacity in existing cement kilns to avoid building new facilities and to access established logistics hubs. The technology was developed at Stanford University and the company was co-founded by Jade Marcus and Dr. Matthew Kanan. Mafix raised $5.4 million in a pre-seed round to fund the demonstration, further R&D across additional feedstocks, and development of next-generation mineral products and applications.

Fast Metals applies a multi-step chemical process—developed by co-founder Sumedh Gostu during his doctoral studies—to red mud, a caustic alumina-refining byproduct, using an additional refinery waste stream to make extraction economical. The process separates iron and sequentially precipitates other valuable minerals, including titanium, aluminum and rare earth elements such as scandium. The company says iron sales cover operating expenses while higher-value products (titanium dioxide, scandium oxide) generate profit; the article cites market prices as context (around $2.50–$3/kg for titanium dioxide and ~$750/kg for scandium oxide). Fast Metals plans to scale up with proceeds from its pre-seed round and has secured a commercial contract with Metalox to treat one ton per week later this year. The founding team includes CEO and co-founder Sumedh Gostu and co-founder Anthony Staley.

Scalvy develops the patented Power Neuron platform, a distributed power conversion and control architecture that places compact, software-coordinated modules with built-in energy storage at load points. The platform is designed to enable megawatt-scale power delivery with higher efficiency, smaller footprint, and grid interactivity without requiring customers to re-architect systems. Scalvy is initially targeting AI data centers, energy storage, and electric mobility markets and has completed technical validation with several blue-chip customers. With the recent Series A, the company has approximately $17 million in total capital raised and is expanding engineering, product, and operations teams. Short-term plans include certification, field testing, and near-term deployments of the Power Neuron platform.

Erg Bio is a Dublin, California–based bioindustrial startup focused on biomass valorization for the production of synthetic aviation fuels and critical chemicals. Its core product, Aspire™, is a low-temperature pretreatment and catalytic system derived from research at Lawrence Berkeley National Laboratory’s Joint BioEnergy Institute. The technology can process more than 30 different biomass types, allowing flexible sourcing of agricultural and forestry residues that would otherwise be discarded. By turning these wastes into high-value intermediates, Erg Bio aims to enhance supply-chain resilience, support rural economies, and advance domestic energy security. The company plans to use newly raised capital to expand engineering and bioprocessing teams, validate the technology technically, and move toward pilot-scale demonstrations. To date, Erg Bio has secured $6.5 million in seed funding; no revenue or user metrics were disclosed in the article.
