Tendril weaves sensing, water intelligence, and conversational AI into the living fabric of your garden and home — hardware that disappears into branches and beds, and an environment that can finally tell you about its day.
Most smart-home gear is a plastic box shouting for attention. Tendril takes the opposite vow: our instruments are shaped like the world they serve. A sensing vine wrapped along a fence line. A watchful coil resting on a branch. Moisture eyes sleeping under the mulch. They listen to soil chemistry, air, water, wingbeats, and weather — and they answer to you, in plain speech, wherever you happen to be standing. Not technology instead of nature. Technology in service of it.
Cisterns, catchment, and irrigation with a nervous system. Every tank level, every valve, every zone — visible and controllable from your pocket, or by simply asking.
Instruments camouflaged as the garden itself, reading what no dashboard ever showed you.
The whole property knows where you are — so wherever you walk, inside or out, your environment focuses on you and simply listens.
A composite of live H2OS telemetry, Sensorium observation, and the Presence voice layer.
If you can spot the device, we failed. Every instrument is shaped, colored, and sited to read as part of the landscape — vine, stone, bark, mulch.
Our hardware has the quiet character of garden fauna — a coil on a branch, a runner along a fence. Things you grow fond of, not things you configure.
No dashboards screaming numbers. Your environment reports the way a good field biologist would — what changed, what matters, what it needs.
We build to deepen your relationship with the place you live — healthier soil, wiser water, more life per square foot. Your land's data belongs to you, and to no one else.
Every H2OS installation is a listening post — soil moisture, cistern levels, rainfall, temperature, life. Now imagine your whole neighborhood connected. The gardens begin to compare notes, and something new becomes visible: the environment starts speaking in sentences instead of words.
A rain front crossing town is recorded cistern by cistern, street by street. Your garden knows the storm is nine minutes away because the gardens uphill already felt it.
Soil moisture block by block. Frost pooling in the low streets. The water table's slow seasons. Bloom and pollinator waves rolling through the neighborhood like weather of their own.
An invasive beetle's front line, moving two streets a week. A dry spell the whole block can budget water for together. What one garden notices, every garden learns.
This is the wonder we're building toward — an environment that doesn't just answer, but converses with itself, and lets us listen in.
Lighting, cameras, sensors, water hardware — curated into packages that fit your place, and planted by installers who work like gardeners, not electricians. Every install is tuned to the site: where the light should fall, where the wildlife moves, where the water wants to go.
H2OS on your existing irrigation and tanks, plus first soil-moisture eyes. The garden starts reporting within a day.
Adds the Sensorium — naturalistic cameras, wildlife and chemistry sensing, and lighting that blends into the planting.
The complete organism, indoors and out: ambient voice everywhere you walk, whole-property awareness, one living system.
The product line we're building toward — installed and maintained by Tendril-certified contractor partners, assembled with allies who build the way we do.
Tendril isn't a rendering. These are live installations where the systems on this page are already listening, watering, and speaking. Two of them are open to visit.
A half-acre hillside garden in Altadena, wired end to end with H2OS and a first Sensorium ring. It waters four zones on its own read of the soil, logs every visitor from bees to the resident scrub-jay, and files a spoken morning report to the owner's phone before coffee. Nine months in, it has cut irrigation draw by a third and caught two plant-stress events before a leaf ever showed it.
● Running since winter 2025An indoor movement gym in Culver City, fitted with a Presence layer that reads the room and answers it in light and sound. Warm-up dims to a low amber hush; a heavy set lifts the room into cool, bright focus; the cooldown lets the light go long and gold as the playlist settles. The coaches steer none of it by hand — they just ask the room, out loud, and it follows.
In build · opens spring 2026Tendril begins as a consultancy, not a factory. We help people and organizations grow AI into their environments — automation that serves the people in the room and the world outside the window. We design AI development environments, build the automations, and train your team to tend them: internal workflows, customer-facing experiences, and physical spaces that listen the way our gardens will. Every engagement sharpens the capabilities the mesh needs — and funds the road there.
Tendril begins where California's water-wise garden movement meets modern AI. Our founding practice has spent thirty years designing native, drought-resilient landscapes — rain capture, dry creek beds, bioswales, habitat planting — and H2OS was born in those working gardens, controlling real cisterns for real clients. The intelligence is new. The care is not.
A garden already speaks — in leaf color, birdsong, and the smell of rain on granite. We're just teaching it your language.
We're not pretending to be a factory — we're a direction, a working water practice, and a set of AI capabilities looking for the rest of the organism. If you're a landscape craftsperson, a sensor engineer, an ecologist, an AI builder, or someone with a garden and the itch to go first — we want to compare notes. Bring a capability. We'll bring the direction.
You're on the list. Here's the brief. We'll write when there's something worth your time.
