Founding Beta · Cohort 01

Recover better to train at your best

A six-week recovery program for runners and athletes to improve their nervous system’s ability to bounce back, so they can push their limits in training

  • 2 × 20-minute sessions daily
  • You’ll need a WHOOP, Garmin, COROS, Apple Watch or Fitbit

The program

Six weeks. Two sessions a day

Two 20-minute sessions a day. Place the electrode clip on your ear and carry on with your day: working, reading a book, taking a meeting. The settings are preset, so there’s nothing to adjust

The science

How Glint works

Glint uses taVNS: transcutaneous auricular vagus nerve stimulation. In plain terms, gentle electrical stimulation at the ear during a preset session

Gentle, non-invasive and well studied

Nothing is implanted, and the current stays low (1–5 mA). In the US, taVNS devices used in clinical research have received the FDA’s Non-Significant Risk (NSR) designation*

A review of 177 taVNS studies with more than 6,000 participants found side effects were mostly mild and temporary, such as tingling, ear discomfort or a headache, and none of the serious events reported were linked to the stimulation. Read the review

*Glint doesn’t hold this designation, or any other certification, yet

The goal

What we’re working toward

Better recovery should show up everywhere: in how you train, how you work and how you sleep. Over six weeks we’ll look for it in your data and in how you feel

  • HRV and RHR

    Evaluate personal trends in HRV and resting heart rate against your pre-use baseline

  • Sleep

    Explore easier winding down, more restorative sleep and changes in overnight measures

  • Recovery and readiness

    Explore feeling more ready between sessions, using wearable scores where available

  • Everyday experience

    Explore feeling less drained after training, more energy for work and fresher the next day

See how we use Glint

We’ve been using Glint on ourselves since September ’26. We’ve seen our HRV and resting heart rate move the right way, and we bounce back faster from our ongoing training fatigue as well

FAQ

Questions, answered

Who owns the device?

You do. The device is yours to keep after the program, with no extra fee for the device or the beta program

Will there be any other charges?

No. ₹14,999 is the total, including taxes and shipping: ₹2,499 now and ₹12,500 after successful delivery, before your guided first session. There’s no subscription and nothing is charged automatically. Future Glint devices will be optional purchases. Terms will be shared when available

What does the daily routine look like?

Two preset 20-minute sessions a day for six weeks: one in the afternoon and one before bed, completed while awake. You can work, read or take a meeting while you wear it. You also wear your wearable to bed every night, which is how we measure your recovery

Which wearables and phones work with Glint?

WHOOP, Garmin, COROS, Apple Watch and Fitbit (including Fitbit Air), with an iPhone or an Android phone. If yours isn’t listed, write to us before you reserve and we’ll tell you honestly whether it will work

When is my baseline set?

At the start of the program. We connect to the wearable you already use and import your last 30 complete nights to set your personal recovery baseline, then follow your overnight data throughout. There’s nothing to connect or upload while you reserve or while you wait

When will my device arrive?

An estimated 20–30 days after your payment is confirmed. We deliver in India only during the beta. If a timeline changes, we’ll tell you the revised window and you can cancel for a full refund

Can I cancel my reservation?

Your ₹2,499 deposit is non-refundable if you change your mind, including before dispatch. You get your money back in three cases:

  • If our health review finds the beta isn’t suitable for you, we refund your full ₹2,499 deposit. This is never treated as a change of mind
  • If we can’t fulfil your reservation, we refund everything you’ve paid
  • If delivery takes longer than estimated, you can cancel for a full refund
What if a session feels uncomfortable?

Stop the session and take the ear attachment off. Tell us what you felt and we’ll work through it with you. You should never push through discomfort or pain

What if the device stops working?

If it arrives faulty, tell us within seven days and we’ll arrange pickup and a replacement or refund. The seven-day arrival-fault reporting window is not a deadline to show recovery benefits and does not end hardware support during the beta. During the six weeks, support and replacement are covered, and we’ll adjust your participation dates for any time lost

What if I don’t notice a benefit?

Everyone responds differently, and benefits aren’t guaranteed. We can’t refund a working device for lack of benefit alone, but hardware faults stay covered. Either way, we’ll go through your data together at weeks 3 and 6

What happens with my health answers?

When you reserve, you’ll answer a few short health questions. If an answer needs a closer look, you can still reserve: we’ll talk it through with you and review suitability before we ship. If we decide the beta isn’t right for you, we refund your full ₹2,499 deposit. Paying doesn’t confirm medical suitability
