Vateris operates a proprietary carbon mineralization process that converts industrial flue gas CO2 into GypCarb, a mineral additive for cement and concrete, while co-producing a mineral fertilizer. Its GypCarb product is positioned as a drop-in additive designed to deliver performance and economic benefits without requiring changes to existing production infrastructure. The company has commissioned a pilot plant and is scaling toward a first commercial plant that would be co-located with a partner to take flue gas directly. Vateris recently rebranded from Concrete4Change to reflect its transition from a concept to a precision carbon-to-materials platform focused on engineering vaterite. To support commercialization and industrial execution it has expanded its commercial team with senior hires from the building materials and fertilizer sectors. The company has secured strategic investment from industry players to validate potential integration into mainstream cement production and European construction chemicals channels.

Lebane is a proptech startup that offers an AI-driven management system functioning as a real-time assistant for construction companies and property developers. Delivered primarily through WhatsApp, the software centralizes financial and operational data, automates tasks such as invoice processing and budgeting, and instantly answers queries on costs, payments and project progress. Launched in 2024, the platform is already entrenched in Argentina and serves 50–60 customers in Mexico, replacing spreadsheet-based workflows with real-time visibility and traceability. With fresh capital, the company will deepen its Mexican presence, solidify its Argentine base and later move into Brazil. Lebane is also building embedded financial products—payments, receivables, yield accounts and contract-backed credit—aiming to evolve into a digital bank for builders. By leveraging clients’ live operational data, it intends to create its own risk score to offer better financing terms. Management targets a three- to four-fold increase in annual recurring revenue and a net revenue retention lift of over 30% while keeping operations efficient.

Gravis Robotics, spun out of ETH Zurich, develops software and AI that transforms excavators and other heavy construction machines into autonomous, driverless equipment. Its systems ingest physical inputs and machine telemetry to enable high-speed responses to varying subterranean forces and soil mechanics. The startup has positioned its technology to operate on real job sites with precision beyond manual control. Financially, Gravis disclosed a $23 million raise in November before completing a $200 million Series A led solely by SoftBank. The company says it will use the new capital to scale its autonomous heavy machinery globally. SoftBank characterized the investment as part of its focus on the fast-growing robotics sector.
