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!

@john_tans Thanks!!
Yes – you can think of Crosshatch as similar to "Continue with Google," but when users sign in with Crosshatch, apps gain access to their personal AI with complete context. Our Link follows standard OAuth 2.0 - you can see more in our docs.
I think the core difference between standard OAuth and Crosshatch is that Crosshatch unlocks access to data and AI resources we manage on behalf of users, whereas, of course, Auth0 is focused on identity and access for applications' backends alone.

Cool launch. I am still trying to understand the top problems it will solve in my day to day life!

@richexplorer We see top applications as:
save time finding products / planning a trip
have apps adjust their settings based on your complete context (e.g., food delivery knows when you're traveling)
get inspired by new products / places you didn't know to search for

@srnlrsn Got it! Thanks for the explanation and as the app has access to your personal data it will be much more personalized than anything out there. Correct?
Crosshatch
@richexplorer Exactly! :-)

@trgorczynski Very much! Loved Disco's "data backpack" - you'll notice too similarities to Anthropic's MCP. The whole point of all of this is to safely + privately interface user data into remote applications.
