Belfort is a spin-off from KU Leuven’s COSIC lab that develops purpose-built hardware to make fully encrypted computation feasible at scale. Its accelerator processes data while it remains encrypted, removing exposure risks to servers, cloud operators, or insiders and opening secure use cases in blockchain, finance, healthcare, and government. The product is already listed on AWS Marketplace and positions Belfort as the first company to commercialize dedicated silicon for encrypted compute. Seed funding will allow the company to double its headcount and expand enterprise pilots out of its San Francisco and Leuven offices. The founding team combines deep cryptographic research experience with industry backgrounds at Intel, Microsoft Research, Kraken Ventures, and Google[x]. Their technology stems from years of ERC-funded research and a competitive DARPA contract, underscoring strong technical defensibility. While revenue and user numbers were not disclosed, the $6 million seed round provides the runway to advance product development and early customer deployments.

Reppo builds a permissionless coordination layer where prediction-market mechanics and staking convert human judgments into verifiable on-chain signals for AI training. Its Datanets are focused sub-networks (e.g., medical, legal, gaming) that act as marketplaces for niche, multimodal data and can be spun up by AI agents or developers; the team aims to reach over 100 Datanets by June 2026. The REPPO token powers participation, requires staking for contributors, has a capped supply of 1 billion and includes deflationary mechanics to reward long-term holders. Reppo reports trading volumes exceeding $2 million in the past month and claims its system can deliver fresh human-vetted data every 48 hours. The protocol emphasizes financial incentives to improve data quality—rewarding accurate contributors and penalizing poor inputs—to address labeling noise and bias common in centralized datasets. Reppo has progressed from a $2 million seed round to the recent $20 million strategic commitment and plans to use the new capital to scale infrastructure, improve protocol throughput, and build integrations for AI teams.
