Hi, I'm Mark, and I think AI should be private 🎒

I’m Mark Heynen—co-founder of Knapsack, where we’re building private AI automations for professionals in finance, healthcare, and other high-trust industries.

Here’s what we’ve learned:

AI can be powerful—but for real work, it has to be private.

That means:

• You control where your data lives

• It runs in your environment, not ours

• It’s grounded in your systems, files, and workflows—not the internet

Most AI tools today don’t meet that bar. They require sending and storing sensitive data to the cloud or adapting your work to fit a chatbot. That’s backwards.

At Knapsack, we’re taking a different path:

• We’re starting with ephemeral compute—models temporarily run in the cloud, but we never store your data.

• We’re moving toward fully on-device AI as hardware catches up.

• And we’re focused on automation, not just answers—because copilots are cool, but getting actual work done is better.

A few trends we’re tracking:

• Compliance is no longer optional—it’s a feature.

• Local AI is closing the gap—fast.

• Professionals want AI that understands their workflows—not some generic assistant.

• The real moat isn’t model size—it’s context and integration.

If you care about private, contextual, and compliant AI— get in touch: knapsack.ai

And I’d love to hear from you:

• What should AI automate in your job that it doesn’t yet?

• Are you ready to trust AI with your most sensitive work?

• How do you want AI to work with your email and meeting notes?

Let’s build this future together.
