Deep work,
without the knock.

Flow Light is a wireless glow for the outside of your door, paired with a single mechanical key for your desk. Press it when you need to focus, and your partner, kids, or roommates see one clear signal: not now, please.

Founding list members get launch pricing. No spam, just build updates.

A knock costs more than a moment. After an interruption, it takes over 20 minutes to fully return to deep focus. A closed door is ambiguous. A glowing light isn’t.

Why Flow Light

Closed doors get knocked on

A shut door might mean “on a call,” or it might mean nothing. Flow Light removes the guesswork, so a knock never throws you out of flow or into the middle of a meeting.

No wires, no outlets

Fully wireless and rechargeable, with weeks of standby on a single charge. The light latches off its mount in one motion when it’s time to top up.

No apps. No accounts. No distractions.

Nothing to pair, configure, or update. One key, one light, one press: a manual trigger for whenever the flow state arrives, or a call needs zero interruptions.

How it works

01

Latch it on

Affix the light to your doorframe or door. Tool-free, renter-friendly, no wires. It stays put for weeks at a time, and pops off in one motion when it needs a charge.
02

Have the conversation

Flow Light only works when the boundary is real. Agree on what the glow means with the people you live with. The light is the framing mechanism, and the clear signal that makes the agreement easy to keep.
03

Hit flow

Not every call is the same. Plenty of them you’d happily pause for a pop-in, and those are the ones you leave the light off for. Save it for the deep work and the calls that actually matter, press the key, and the glow means something. A dark light is an open door.

Two pieces. One press.

The Key

A real mechanical switch with a weighted, tactile press. Built for the kind of desk where every object was chosen on purpose. It lights up to match the glow outside, so one look tells you what your door is saying.

The Light

A soft, unmistakable glow for the outside of your door. Minimal when off, obvious when on, and visible down the hall without lighting up the house.

Questions, answered

When does it ship?

Flow Light is in the prototype phase. We’re gathering the founding list now and will share timelines with the list first, as soon as we have dates we trust.

How much will it cost?

Final pricing isn’t set. Founding list members get launch pricing, meaningfully below what it will sell for afterward.

Will it damage my door? I rent.

No screws, no drilling. The mount latches onto the doorframe or door and comes off clean. Designed with renters in mind.

How long does the battery last?

Weeks of typical use per charge. When it’s low, the light unlatches in one motion and recharges over USB-C.

Does it need Wi-Fi or an app?

No. The key talks directly to the light. Nothing to pair with your phone, no account, no firmware nags.

Will it work with kids?

Flow Light is a signal, not a lock. It works exactly as well as the agreement behind it. Families tell us the ritual helps: kids learn “glow means wait” faster than they learn “closed door means wait.”
