Blue Tulip Ventures invests in early stage startups building Human Centric AI – AI that is good for you, good for the planet and is ethical. We believe AI will be transformative and will offer massive economic opportunity, but it has to be done right. We believe AI needs to be in service of humanity, supporting us to be healthier, happier, more productive and connected … enhancing what it means to be human in the age of AI. We believe AI can help protect our planet, through food innovation and sustainable living, address the impact of climate change and power scientific discovery. We believe AI needs to be developed and used ethically, ensuring it does not cause harm to humans or the planet, and that it is transparent and safe with proper governance.

Stealth AI Startup is an independent initiative focused on founders building AI companies before public launch. We explore the earliest stages of building an AI startup—from testing an idea and finding collaborators to assembling a team and preparing to launch. Our focus: • Founder experiences and lessons from building in stealth • Emerging AI technologies and startup trends • Perspectives from founders, researchers, engineers and investors • Practical learning for the journey from idea to launch We believe founders can exchange knowledge and build meaningful professional connections while keeping their products and plans confidential. This is the official LinkedIn Page of the Stealth AI Startup initiative. It represents our initiative, rather than the separate companies built by founders who follow it. Following or engaging with this page does not, by itself, establish employment, partnership or endorsement. Follow us for perspectives on building AI companies and updates from our initiative.

The first Behavior Design Engine for the enterprise. Sequen isn’t retrofitted AI search or recommendations. It rethinks relevance from first principles. Sequen introduces the first foundational Large Event Model (LEM), trained on billions of user event sequences and built natively on a reinforcement learning infrastructure. LEMs are specialized neural networks that predict the next user event—just as LLMs predict the next word. Sequen’s LEMs are pre-trained on billions of user-site interactions and fine-tuned to optimize for the outcomes you care about. No more fixed pipelines with fragmented infrastructure. Sequen replaces them with a single endpoint that adaptively handles all phases of personalization via LEMs and memory models—all through a sub-25ms API.
