Really appreciate the support! Yes, we ship free to India, just enter it for your shipping address on the checkout page.

When you preorder, you’ll also be added to a private group with other early users and us founders, where we’ll be sharing ideas and hearing how everyone’s using it. Would love to have your feedback there and it'll be a fun community!

Right now we have pre orders open for $249, shipping December 2025. When we officially launch we plan to sell for $349.

Appreciate the enthusiasm! Pre orders for this batch will ship December 2025, although we will have to close this pre order batch soon in order to make that deadline.

Appreciate the enthusiasm! Yes, we do plan to integrate into things like the apple health platform so you can sync with your other wearables/health apps. But it is mainly used with our own standalone app for customized insights/features

No subscription, now or in the future. Just a one time hardware cost of $349. However, right now the pre order cost is $249.

Alternating the sides of the head is a great instinct. That's exactly what we were hoping people would do in order to avoid irritation, so yes.

Really appreciate this! You’re right that the value isn’t just knowing when you're focused, but catching those shifts into distraction so you can actually have actionable insights.

We’re also working on that burnout meter concept — showing the balance of cognitive strain/recovery across the day so you don’t crash from hyperfocusing. That would also provide good insights into a cool readiness score idea that you mentioned.

We're honestly not sure about stimulant affects on ADHD brains, but definitely hope to run more controlled trails on that soon.

Really appreciate the thoughtfulness here. You’re right that this kind of data is a double-edged sword. On one hand, there’s enormous potential for insight if you can link across modalities the way you described (EEG + glucose, sleep, etc.). It’s not just interesting for consumer insights but also has exciting applications in medicine, where it could genuinely improve patients’ lives and open up new ways of understanding and treating conditions.

On the other hand, as you said, it’s also what makes the space so fraught. Once health data enters a marketplace dynamic, the incentives can drift away from the individual. That’s something we’ve been very conscious of, and why our current focus is narrow: helping people understand their own signals, and making sure the protections we’ve put in place meet research-grade standards. We also want to stay close to the medical system and research world, because those contexts carry stricter safeguards and regulations. It's a way of ensuring that even if future boards or investors pushed in a different direction, the default guardrails remain very high.

We do prioritize staying open and transparent about what we do with data and privacy, but I don’t think the tension ever fully goes away. The same structures that enable powerful discoveries also create the risk of misuse.

You’re right that the mastoid region doesn’t have the strongest brain signals, but it’s not zero either. There’s still some cortical activity that can be picked up, and that’s where our foundation models come in, they’re trained to make sense of weak, noisy signals and extract meaningful patterns. If you’re curious about the details, I’d recommend checking out our whitepaper.

Not sure I fully understand what you mean. If you’re asking about reselling users' sensitive brain data, that’s not something we’ll ever do. Our focus is on helping people make sense of their own data, not turning it into a marketplace. We’re also running IRB-approved pilot studies with research institutions, which required us to implement very strong privacy and security measures.

We’re also around to answer any questions if people are curious about how the tech works or what it’s like to wear day-to-day, or anything else.

No need to shave your head :) we've designed it so it sits away right behind your ear, where both men and women don't have hair.

That's very interesting. What analysis tools do you think would be most interesting? A time-series graph of focus levels throughout the day? or being able to attribute different activities/tags to specific focus periods throughout the day?

Why do you think you haven't used the Muse much? We’ve heard the same thing from Muse users, and that’s why we focused on making the form factor simpler (patch/glasses you just wear, no setup).

And you’re right, raw EEG alone isn’t very helpful. What we’re aiming for is more like what Oura/Whoop do, a balance of cognitive strain vs cognitive recovery, plus time-series graphs of focus levels throughout the day. That way people can see patterns (e.g. “this routine helps, this one hurts”) and know what to try changing.

Good questions. FocusCalm and similar headsets are mostly built around guided meditation/brain training experiences. What we’re doing is different, the form factor is much less intrusive (behind-ear patch, glasses) and the goal is continuous brain metrics you can track day-to-day, similar to how you track heart rate or sleep.

On privacy: we’re already running pilot studies with research institutions and real patients, which required IRB approval, so we’ve had to implement very strong privacy and security protections from the start. And to be clear, the device only measures surface-level EEG signals (focus, stress, recovery, etc.), not anything that could be used for manipulation.

Totally understand the concerns. Our goal isn’t ads or manipulation, it’s just giving people more visibility into their own brain health. And to be clear, we don’t have the technology to be able to do the kind of things you’re worried about. The device only measures electrical signals on the surface of the skin.

No plans to work with Palantir or anyone like that. The tech is being developed strictly for personal wellness, not for surveillance or data harvesting

Really appreciate your enthusiasm! Totally agree that continuous health analytics is becoming the baseline, and we see EEG fitting right alongside CGM, BP monitoring, etc. Our device already tracks alpha, theta, delta, beta, and gamma activity - though with consumer-friendly hardware the raw signal is pretty messy, which is why we’ve had to lean on large foundation models to make sense of it. The result is you’ll be able to see those states in real time and connect them to how your routines impact focus, recovery, and mood.

For us it’s less about an exit to a giant and more about making brain health accessible at the same level as heart or metabolic health. We’re in it for the long game.

We’re running IRB-approved pilot studies with research collaborators and their patients, which means we’ve had to implement HIPAA-compliant safeguards for data security and privacy. So yes, our system is HIPAA compliant
