Harell Data is building the intelligent infrastructure for the next era of scientific discovery. While AI has revolutionized digital industries, progress in the physical sciences-from drug discovery to material science-is currently bottlenecked because the most valuable training data remains isolated, unorganized, and difficult to access. We are solving this by providing an end-to-end ecosystem that enables the secure sharing of proprietary datasets alongside the high-performance compute and orchestration layer required to train large-scale models. By bringing compute to the data within a single, integrated environment, we are creating the foundational stack that transforms raw scientific data into the next generation of domain-specific foundation models.

Sahova is building the first AI-native operating system for construction. We believe the future of construction isn't another project management tool—it's an intelligent operating system that understands every project, document, conversation, and workflow. Our mission is to simplify and advance how builders and contractors run their businesses through AI.

AI companies are flying blind on cost. They know their AWS bill. They don't know which product, customer, or feature is eating their margin. Finance leaders at AI-native companies are stuck piecing together cost data from dashboards built for engineers. By the time they have a clear picture, the decision window has passed. Tonifo is the cost intelligence layer built for the finance side of AI. We give CFOs and finance teams real-time visibility into which products are profitable, which customers are driving spend, and where AI API costs are eroding margin, without needing an engineering ticket to get the answer. We're pre-seed, moving fast, and talking to finance leaders at AI companies who are tired of not having the numbers they need to make calls with confidence.
