Hey Product Hunt! 👋 I’m Soren, co-founder of Crosshatch. We’re thrilled to share what we’ve been building.
What is Crosshatch?
Crosshatch is the API for complete, real-time user context. It lets users securely bring their habits, behaviors, and preferences to your app—in as little as a single tap.
Why did we build this?
AI-driven personalization is fundamentally broken. Apps don't know who we truly are, what matters to us, or how to adapt to our changing needs.
To compensate, apps and agents push us through long onboarding flows that are tldr and still fail at real personalization. This results in experiences that feel generic, invasive, or just plain wrong.
We asked ourselves: Instead of apps tracking us, what if we could bring our own context and AI? With just four lines of code, Crosshatch enables apps to instantly access complete, real-time user context—delivering personalization that feels intuitive, not intrusive.
What makes Crosshatch different?
🚀 Real-time adaptive personalization: Unlike CDPs or memory layers, Crosshatch dynamically updates based on user activity from across all connected apps. Apps can subscribe via webhooks, making personalization genuinely adaptive in near real-time.
🔐 User-driven privacy: Inspired by Apple-style permissions, users control exactly when, how, and for what purpose data is shared—either “while using” or “always.”
💡 Zero-friction developer experience: Just one simple AI API call delivers instant, permissioned user context, transformed by top LLM models.
What’s next?
We're laser-focused on empowering developers to build the next generation of AI-driven, hyper-personalized apps. If you’re working in AI, consumer tech, or personalization, we’d love to connect!
