CROSSK is building Whitebrinjal — an AI-driven decision infrastructure for complex enterprise technology procurement. Enterprises struggle to evaluate emerging technologies because the hardest work happens before procurement: defining the problem, aligning stakeholders, comparing unfamiliar solutions, validating fit, and building the business case. Whitebrinjal structures this fragmented pre-procurement journey into a decision layer—helping enterprises move from complex problems to decision-ready engagement with the right technology providers, while helping providers reach qualified enterprise opportunities with context, intent, and stakeholder alignment. We are solving the gap between “we have a complex problem” and “we know what to buy, why, and from whom.”

The architectures that power modern AI were designed for language, not for science. They were never built to understand DNA, interpret experiments, or learn the rules that govern living systems. Closing this gap represents one of the defining opportunities of our time. Our team has pioneered advances across frontier AI, including the first models trained with one-million-token context windows, and now scaling toward one billion. We focus on innovations on systems and architecture, because building AI for science demands a fundamentally different foundation. As a first application of this technology engine, we are advancing AI for life, the most complex and consequential domain of all. We are the AI team behind Evo and Evo 2, the generative genomics models used to create real gene-editing tools and the first whole genomes designed entirely by AI. That work demonstrated that AI can create biology, not just analyze it. We are now building multimodal models trained directly on the fabric of biology, enabling faster discovery, deeper understanding, and entirely new capabilities. As we push the frontier of scientific world models, we will build systems hand-in-hand to ensure global biological resilience: rapid detection, rapid response, and rapid countermeasures against emerging threats, both natural and synthetic. Our mission is ambitious: to reimagine what AI can do for science, and to build that future.
