Time Machine

Time Machine lets you record — audio, video, photo, writing — and leave it in the exact place it was made. It can only ever be experienced by physically returning to that place. Nothing on Time Machine can be viewed remotely, forwarded, or fed. Content made here is never consumable there, by design.

Leaving is a single, intentional act: recording and placing happen at once, because the coordinates where you record are the only coordinates where the recording will ever exist. Leaving doesn't publish a recording. It plants it — geolocation-gated to the exact spot, invisible and inaccessible anywhere else on earth. Returning is the key. Relive is what happens when presence and place align.

Every mainstream platform is built to answer one question: how far can this content travel? Reach is the value metric. Time Machine is built on the opposite premise — a recording is most meaningful at zero distance from its origin. We optimize for return, not reach.

A space is just coordinates. A place is a space someone has lived in.

Standing where a recording was made, you aren't scrolling past someone's decontextualized present. You're standing inside your own past, and it hits like time travel.

The moment you let content made here be consumed there, you've built a distribution platform and joined a war you can't win. Our refusal to distribute is the product. Everyone else turns place into content. We turn space into place.

Live on iOS and web. No revenue, no paying users yet. Roughly 20 friends on the app and web client, ~40 users through intimate events (Hilgard Avenue, Cafe Time Machine). Broader reach through physical installations — Grizzly Peak, Phi Psi Surfrider, Memorial Glade, Kibera — where participants left written and audio input off-app.

Stack. Native iOS (Swift/SwiftUI) with an on-device audio and ML pipeline (SoundAnalysis/Core ML, vDSP, Speech) for key/tempo, species ID, speaker, mood, scene, and transcription. Firebase backend (phone-first auth, Firestore, Storage, Node Cloud Functions), web client, and a tmkit SDK. Claude handles server-side curation and moderation. Built almost entirely with Claude Code.

Roadmap. Fully spatial output — media that follows the listener across space, preserving tempo, pitch, and timbre relative to how it was recorded. Beyond that, place-conditioned models: models that live in one place, trained on data that exists only there.

The first market is a university, not a city — and the first is Berkeley. Campuses are the highest-ritual, highest-density, cheapest, most creative-supply-rich places on earth, and the founder is already embedded there. It's Facebook's move — launch one campus, prove it, spread campus to campus — and it fits Time Machine even better.

Corridor #1: the Berkeley campus. One saturated, visible corridor, seeded by people the founder already knows, proving the density-and-return curve before a dollar goes to a new market.

Not one silver bullet, but a sequence of streams, seeded locally and scaled through the substrate. Per-place economics funds early density and proves the model; the platform layer is the venture-scale upside.

The 18Birdies note. For their golf app, club-by-club proved operationally heavy and a universal subscription scaled better. Not a verdict for us — our per-place events are also marketing and supply — but a caution: watch the cost of many small venue deals, and treat a universal subscription as the likely durable backbone if the per-place hustle gets heavy.

Never sell user data. Presence-gated memory is the brand and the moat.

We won't claim we can size the substrate line credibly yet. What we can say is that it never requires crossing the one line the whole company is built on: turning someone's presence into something we sell to anyone other than the person who was standing there.

Asset-light to prove, owned to profit. Uber owns no cars until it knows the route; McDonald's owns the real estate under the franchise; Kirkland owns the label while shelving the rival. Time Machine climbs the same rungs — and the café down the street still feeds you reach after you own the flagship.

Own only what you've proven with usage. Earn the right to own, the same way a place earns its machine.

Ignore total installs — the only vanity metric. Track aliveness and raise on the curve.

Not the near-term driver; a mode we grow into. Prove the model on Berkeley first. We won't have to push: once one campus is undeniable, the next ones ask. A light apply-to-earn-in gate lets a campus prove it's ready — a champion, an artist roster, committed venues, a scene — which pre-seeds the supply and siting a launch needs.

Keep it warm and accessible, never velvet-rope. The gate is about readiness and density, not status; Time Machine is populist. And it pays: earning in makes college fun, piggybacks existing clubs, and turns campus pride into free marketing. The applicant queue is itself demand proof for investors.

It's geocaching with a party to fill each bucket — and we sell the party. Geocaching proves a global network of millions of presence-gated, community-placed sites works with almost no central operations. We add the media, the memory, the artists, the curation, and the ritual.

Every meaningful place on earth holds its own memory, authored by the people who were there, gated by presence — and a traveler anywhere sees a hexagon and knows the ground beneath them is remembering.
