Looks great. Not sure how big the market is between "need max privacy, need on-prem" and "don't care, just use what is cheap/popular" tho. Can you talk about how this relates to / is different / is differentiated from what Apple claimed to do during their last WWDC? They called it "private cloud compute". (To be clear, after 11 months, this is still "announced", with no implementation anywhere, as far as I can see.)…

Private Cloud Compute has been live in production for 8 months

Companies like Edgeless Systems have been building open-source confidential computing for cloud and AI for years, they are open-source, and have published in 2024 how they compare to Apple Private Cloud Compute. https://www.edgeless.systems/blog/apple-private-cloud-comput...

How do you see this compare to things like Amazon Bedrock, where it runs OSS in my own infra?

Bedrock has strong contractual guarantees, but it's still only a legal contract and runs on AWS infra. This is certainly okay for many use cases, we're trying to build for users who want verifiable privacy guarantees beyond legal contracts.

We're also doing more than pure inference, and trying to work with other companies who want to provide their users additional verifiability and confidentiality guarantees by running their entire private data processing pipeline on our platform.

Does this not require one to trust the hardware? I'm not an expert in hardware root of trust, etc, but if Intel (or whatever chip maker) decides to just sign code that doesn't do what they say it does (coerced or otherwise) or someone finds a vuln; would that not defeat the whole purpose? I'm not entirely sure this is different than "security by contract", except the contracts get bigger and have more technology arou…

We have to trust the hardware manufacturer (Intel/AMD/NVIDIA) designed their chips to execute the instructions we inspect, so we're assuming trust in vendor silicon either way. The real benefit of confidential computing is to extend that trust to the source code too (the inference server, OS, firmware). Maybe one day we’ll have truly open hardware ;)

Hi Nate. Routinely your various networking-related FOSS tools. Surprising to see you now work in the AI infrastructure space let alone co-founding a startup funded by YC! Tinfoil looks über neat. All the best (:

This is a great concept but I think "Enterprise-Ready Security" and your competitive comparison chart are kind of misleading. Yes, zero trust is huge. But, virtually everyone who has a use case for max privacy AI, has that use case because of compliance and IP concerns. Enterprise-Ready Security doesn't mean sigstore or zero trust, it means you have both the security at a technical level as well as certification by an auditor that you do.

You aren't enterprise ready because to address those concerns you need to get the laundry list of compliance certs: SOC 2:2, ISO 27k1/2 and 9k1, HIPPA, GDPR, CMMC, FedRAMP, NIST, etc.

We're going through the audit process for SOC2 right now and we're planning on doing HIPAA soon
