❓ What You’ll Learn

  • Why can someone subpoena the AI chats you deleted?
  • How do you charge for AI that physically can’t read your data?
  • Which 7 businesses can you start in the gap between encrypted AI and merely “trusted” AI?
  • How much do idle MacBooks really earn overnight?
  • What vault attack, Helium economics or Apple clause could sink a company built on this?


💎 Why It Matters

Blind AI inference launched at or below the price of the kind that can read your prompts.

The choice between privacy and capability just collapsed.


🔍 Problem

You paste a contract, a diagnosis or your source code into AI to get real work done.

That prompt now lives on someone else’s server, under their retention policy and any court order they get.

“Delete” turned out to mean “retain, segregate and produce in discovery.”


💡 Solution

Blind AI companies run your encrypted prompt inside a sealed hardware vault that even the machine’s owner can’t open, so the server side can’t read what it serves.

Encrypted on your device. Attested before it runs. Decrypted only for you.


🏁 Players

Blind Inference Providers

  • Darkbloom • Operator-blind inference on idle Apple Silicon Macs, priced ~50% below API rates. The supply-side wild card.
  • Tinfoil • YC-backed confidential inference plus a $20/mo private chat. The cleanest “trust the hardware” pitch.
  • Confer • Signal creator Moxie Marlinspike’s E2EE chatbot, now being integrated to underpin Meta AI.

Confidential Clouds

  • Apple Private Cloud Compute • The reference architecture: stateless Apple Silicon servers Apple itself can’t inspect, now expanding onto Google Cloud.
  • Microsoft Azure • Furthest-along hyperscaler: confidential VMs pairing AMD SEV-SNP with H100s plus a managed confidential inferencing service.
  • NVIDIA Confidential Computing • The shared silicon: H100 and Blackwell GPUs with GA confidential computing that nearly every startup here rides.

Consumer GPU Networks

  • Salad • The largest consumer network: 60,000+ daily active GPUs across 450K+ nodes, where the host can in principle observe the workload.
  • Aethir • The revenue leader: reported $39.8M Q3 2025 revenue across 435,000+ datacenter-grade GPU containers.
  • io.net • Solana-based GPU aggregator processing up to 4B AI tokens per day after an $8M enterprise deal.

Local and Adjacent Tools

  • Ollama • The default local-model runner. Privacy by locality, free locally, with a $20/mo cloud tier that reintroduces a trusted operator.
  • LM Studio • Free desktop GUI for local models where data never leaves the machine.
  • Exo • Open-source clustering of your own Macs into one inference machine. Darkbloom’s closest technical cousin minus the marketplace.


🔮 Predictions

  • A frontier lab will sell operator-blind access to a proprietary model.
    • The model developer is the one party a logged API can’t hide from, which is exactly what a hardware vault removes.
    • Providers in the lane serve open weights today, leaving blind access to GPT, Claude and Gemini as unmet demand.
    • Apple now runs Apple Intelligence on Google Cloud vaults it doesn’t own, proving frontier models can run blind on rented silicon.
  • Courtrooms will outpace regulators as the demand driver. A major AI vendor will market “we can’t produce what we can’t read.”
  • The privacy premium will stay at zero. Blind inference prices at or below standard rates.
    • Competition removes any pricing-power basis for a privacy upsell.
    • Vault overhead is measured below 7%, so there’s no cost basis for a markup.
    • Comparable open-weight models run $0.10-0.15 per million tokens on commodity providers. Blind providers launched under that.
  • A public side-channel break of GPU confidential computing will force fleet-wide re-attestation.
    • Apple’s $1M PCC bug bounty prices how much a break is worth.
    • GPU vaults went generally available with CUDA 12.4 and carry far more value per machine, making them the most attractive unbroken target.
    • CPU vaults have fallen repeatedly: WireTap pulled Intel SGX keys with a sub-$1,000 interposer and Battering RAM bypassed AMD SEV-SNP for ~€50.


☁️ Opportunities

  • Ship the “LiteLLM of blind AI”. Offer one proxy that encrypts, attests and routes to the cheapest vault provider.
    • AI gateways are already how developers route open-weight inference.
    • The wedge is friction. Change one base URL and your app stops leaking prompts.
    • Providers in the lane are OpenAI-compatible by design, including Tinfoil keeping your existing OpenAI clients.
  • Launch the blind-AI benchmark site.
    • Providers differ on price, latency and attestation, from post-quantum encryption inside Intel TDX and NVIDIA CC to re-attestation clocks that range from seconds to hours.
    • Build the Artificial Analysis of private inference. Monetize with enterprise API access. The site becomes the category’s front door.
    • Few track them side by side today.
  • Start a Mac-fleet supply business for agencies and schools with idle racks.
    • Individual owners earn beer money, which is exactly why aggregated fleets are the play.
    • Handle onboarding, uptime and payouts for a management cut while early-mover margins are best.
    • Roughly 110-130M Apple Silicon Macs have shipped since 2020. Agencies own racks that sit idle 16+ hours a day.


🏔️ Risks

  • Helium Economics • Consumer-node payouts are hobby-grade. DePIN supply leaves when incentives normalize.
  • Prospective Compliance • No EU regulator has blessed attestation, so “compliant by hardware” stays an argument until one signs.
  • Apple License • Multi-tenant inference on strangers’ Macs runs on Apple’s certificates in untested territory.


🔑 Key Lessons

  • Courtrooms are the category’s best salespeople. Sell to the subpoena-afraid first: legal, HR and M&A feel discovery risk in their bodies.
  • Trust is migrating from terms of service to silicon. Ask for attestation before a DPA. Build so your privacy claim is a hardware property you can verify.


🔥 Hot Takes

  • The next AI moat won’t be the model. It’ll be what you can prove you never saw.
  • “We can’t read it” beats “we won’t read it” in enterprise deals from here out.


😠 Haters

“You sealed the box. What about the pipes?
Even a blind vault can’t help if the prompt travels in weakly or the answer gets logged after your device decrypts it. The strong builds encrypt the channel end to end and pin the endpoints, so the sealed middle and the secured ends form one chain. The weak ones leave a gap that reaches the same exposure inbound or outbound.

“Local AI eats this from below.”
A good local 14B model is free and private by default. The counterweight is the strongest fact here: Apple, the on-device champion, moved frontier Apple Intelligence to cloud vaults because frontier models exceed what a laptop holds.

“The node operator is exactly the attacker vaults don’t defend against.”
A stranger’s Mac is physically held by the person you’re hiding from, where CPU vaults have already fallen to sub-$1,000 attacks. GPU vaults have no public break yet. The new PCC design uses two independent roots of trust so one broken vendor isn’t fatal.

“Nobody pays for privacy. The prices prove it.”
Tinfoil charges ChatGPT Plus parity and Darkbloom launched below market, so the premium really is zero. That cuts the other way: features priced at zero become defaults. Defaults eat markets.
