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.”

Alexandria is a reading platform built around a simple observation: people read more than ever and remember less than ever. The average person forgets most of what they read within a week. Not because of a memory problem. Because the tools were designed for consumption, not understanding. Alexandria brings articles, podcasts, YouTube videos, books, and PDFs into a single library. It reads content aloud with synchronised word-by-word highlighting so you stay focused. Then it goes further. The platform automatically extracts key concepts from everything you consume, connects related ideas across different sources, and uses spaced repetition to bring knowledge back before you forget it. The project started as FlowRead, a Chrome extension that combined text-to-speech with real-time word highlighting. The founder, Elliott Tong, built it after struggling to read technical documentation post-workout and realising no tool on the market would read with him rather than just at him. The extension worked, but it revealed a deeper problem. Knowledge is scattered across dozens of apps and none of it connects. Read-it-later tools optimise for clearing backlogs. Note-taking apps become graveyards. AI chat tools give answers that vanish into conversation threads you never revisit. Alexandria is named after the ancient library because the mission is the same: one place where understanding can live, be accessed, and be built upon. It is designed for students, professionals, ADHD readers, and anyone who consumes knowledge across multiple formats and wants it to actually compound over time.
