Why Did the Humane AI Pin Fail? Lessons for Hardware Founders

The Humane AI Pin failed because its core functions depended on a live cloud connection the company could not sustain, compounded by thermal and battery limits reviewers flagged at launch. Humane sold the $699-plus-subscription wearable starting in April 2024, and by February 2025 it had sold its software and patents to HP for $116 million and shut down the servers every Pin needed to function, leaving existing devices unable to call, message, or answer an AI query within ten days of the announcement.

What happened, in order

Why the device stopped working when the company did

The Pin’s core features were built around a cloud connection from the start. It used its own built-in cellular connection rather than pairing with a phone, and most of what it did, including answering spoken questions, depended on sending data to Humane’s servers and getting a response back: one widely cited reviewer summary noted that voice query delays happened because most requests went to the cloud, not the device itself. When the servers stopped, there was no local fallback, so working hardware became unable to do most of what it was bought to do.

This is the same decision Inventornest’s own AI in IoT devices guide walks through for any connected product: whether a feature genuinely needs the cloud, or could run on the device and keep working without a server on the other end. In our experience at Inventornest, we advise against connectivity that adds cost and complexity without solving a meaningful user problem; if a product can perform its essential function reliably without an app or cloud connection, a standalone version may be more appropriate. The Pin’s value depended on the opposite choice, which is also why its failure was total rather than partial.

The thermal and battery limits reviewers flagged

Independent reviews published within days of launch converged on two recurring complaints, with one point of disagreement.

• Multiple outlets reported the device ran hot to the touch during ordinary use in their April 2024 reviews, and TechRadar’s review roundup described reviewer Marques Brownlee’s reaction to it as “worryingly warm a lot of the time.”
• CNET’s review separately listed overheating as a named drawback.
• The New York Times reported that Humane executives used ice packs to cool devices before demonstrations, and that its laser projector display was meant for no more than nine minutes of continuous use.
• Reviewers disagreed on battery life: several called it weak or inconsistent, roughly four to five hours on the built-in battery alone and longer with an add-on battery pack, while CNET listed battery life as a positive. The criticism was widespread but not unanimous.

In our experience at Inventornest, battery optimization is often underestimated: a prototype can perform its main function successfully but still deliver inadequate battery life in everyday use, which can require another design iteration or, in substantial cases, larger redevelopment.

What happened to the company, and to owners

HP’s $116 million acquisition, announced February 18, 2025, took Humane’s AI software platform, a patent portfolio of more than 300 patents and applications, and most of the team, including co-founders Bethany Bongiorno and Imran Chaudhri, who joined HP’s new internal AI lab. The hardware product was excluded and discontinued. Refunds went only to customers whose device had shipped on or after approximately November 15, 2024, roughly a 90-day window before the announcement; earlier buyers got none. The Consumer Product Safety Commission’s recall notice for the charge case accessory now states its remedy “is no longer available” because the company that would have provided it has closed, and tells remaining owners to discard it.

What end-of-life planning for connected hardware actually looks like

The Humane AI Pin is not the only connected device that stopped working when its backend did. Jibo, a social robot, had its servers shut down in 2019 after its assets were sold; it delivered an on-device farewell message and kept a limited wake-word response but lost most of its functionality. Spotify’s Car Thing stopped selling in 2022, and the company announced in May 2024 that it would stop working entirely, which it did on December 9, 2024, with owners told to dispose of it through local e-waste programs.

The National Institute of Standards and Technology’s research on smart-home device loss of support found that a meaningful share of U.S. consumers worried their devices would simply stop working once support ended. Its recommendations for manufacturers: publish end-of-life policies and expected lifespans in advance, disclose when security patches stop, notify customers by email, and describe how a device can keep operating safely in reduced form rather than becoming fully inoperable.

Lessons for hardware founders designing for the day the cloud goes away

None of this requires predicting that a company will shut down, only deciding, before launch, what a device should still be able to do if its backend ever goes away.

• Separate what must run locally from what genuinely needs the cloud. A device whose core job works offline degrades gracefully; one routed entirely through a server fails completely when that server stops.
• Disclose a support period before launch, not after. Stating up front how long cloud features will be supported sets an expectation a sudden shutdown then breaks.
• Treat battery and thermal performance as core requirements, cheaper to fix during feasibility and prototyping than after a product has shipped.
• Plan a wind-down path, not just a launch path. A device with no answer for what happens if the cloud service stops is designed to become e-waste the day support ends.

Frequently asked questions

Why did the Humane AI Pin stop working?

Its core features, including calling, messaging and answering AI queries, depended on a live connection to Humane’s servers. When the company shut those servers down on February 28, 2025, those functions stopped working on every existing device, because there was no offline fallback built in.

Did Humane go out of business, and can owners get a refund?

Humane’s software, patents and most of its team were acquired by HP for $116 million in a deal announced February 18, 2025; the hardware product was not part of that deal and was discontinued. Refunds went only to customers whose device had shipped on or after approximately November 15, 2024; earlier owners were not offered one.

What does “bricking” mean, and why does it happen to connected devices?

“Bricking” describes a device becoming non-functional, effectively as useful as a brick, usually because a server or companion app it depends on has been shut down, and its essential functions were never designed to run on their own.

How can hardware founders avoid building a product that depends entirely on the cloud?

By deciding early which functions genuinely need cloud processing and which could run on the device, and building the core function to work, even in reduced form, without a live connection. That decision belongs in feasibility and early design, not as a fix after launch.

What other devices have failed for similar cloud-dependency reasons?

Jibo, a social robot, lost most of its functionality when its servers shut down in 2019. Spotify’s Car Thing stopped selling in 2022 and stopped working entirely on December 9, 2024. Both depended on a backend their maker later turned off.

Where Inventornest fits

What should run on the device, what needs the cloud, and what happens if that cloud goes away are feasibility questions, not afterthoughts for once a product ships. In our experience at Inventornest, we always prefer to begin with technical feasibility, whether the idea is simple or complex, because that is where these dependencies get identified and tested before a company has committed to a design it cannot change cheaply.

If you are weighing how much of your product’s core function should depend on a live connection versus run on the device itself, that is exactly the question a technical feasibility analysis is built to answer. Inventornest’s IoT product design services cover that decision as part of the wider build; the next step is to book a consultation to talk through where your product’s dependencies should sit.
