TLDRVyana, founded by Arjun Gupta, introduces a smart ventilation system that replaces, not dilutes, indoor air. Using CO₂, VOC, and pollen sensors with predictive algorithms, it optimizes airflow for health and energy savings (~15% in early tests). With sealed dampers, washable filters, and $250–$300 pricing, Vyana aims to make fresh air an algorithmic decision.via the TL;DR App

I don’t usually cover early hardware unless there’s something genuinely new under the hood. Vyana got my attention after I came across a post about founder Arjun Gupta and his presentation at an Antler hosted HW session in Austin. His pitch wasn’t vapor; it was the rare mix of founder-with-a-scratch-your-own-itch story, thoughtful engineering, and the scars you only get from building real devices.

The problem I care about (and you probably do too)

We spend most of our lives indoors, and indoor air can quietly get gross—stale CO₂, lingering VOCs, pollen wafting in when you crack a window at the wrong time. Add energy costs and you’ve got a daily optimization puzzle: how do you swap bad air for good air without chucking your conditioned air (and money) out the window?

The founder, in one paragraph

Arjun is a computer engineer turned repeat founder who later spent nine years in product roles at Dell. He’s built and scaled consumer businesses (one reached ~3M customers through ~1,200 retail points in India) and then went deep on data-driven ops at Dell before returning to hard tech. The origin story here is simple: pandemic dog walks felt better outside than inside; he dug into the why, and started tinkering.

What Vyana actually is

Vyana is a smart ventilation unit that focuses on air replacement, not dilution. Think two coordinated fans—one exhausting stale indoor air, one bringing in filtered outdoor air—plus sensors and a predictive control loop.

  • Sensors: CO₂, particulates (PM2.5/PM10), VOCs, temperature, humidity.
  • Brain: an embedded controller that uses indoor readings + local weather/pollen data to decide when to exchange air.
  • Form factors: a 6-inch wall mount (dryer-vent sized) or a window mount for renters or the hole-averse.
  • Filtration: a washable MERV-8 (MERV-7/8 in recent docs) with optional activated charcoal; intentionally not HEPA to keep airflow high while still nailing pollen.
  • Sealing: motorized dampers close when idle so you’re not leaking conditioned air.
  • App: onboarding, live air metrics, simple modes (auto/sleep/boost), runtime history, filter reminders; future integrations with thermostats/smart home.

The “replace-don’t-dilute” bit matters. Many “fresh air” add-ons just inject a trickle of outside air and hope for the best. Vyana’s paired flow creates a pressure gradient to push old air out while pulling fresh air in, which is more deterministic—and measurable.

Why this isn’t another pretty render

Three things put Vyana on my “plausible” list:

  1. Data-first control: The device looks at CO₂/PM/VOC trends and forecast windows when outside air will be healthier/cheaper to use. That lets it shift ventilation to off-peak or low-pollen times and has shown ~double-digit HVAC energy savings in early tests (the claim is ~15% in line with lab research on smart ventilation).
  2. Manufacturing math that pencils: Prototype costed bill of materials suggests retail around $250–$300 with hardware margins that don’t rely on miracle scale. Filters are washable (annual replacement), with optional consumables (aroma pads) for recurring revenue.
  3. Founder with the right scar tissue: Arjun is candid about early mistakes—paying for market validation too soon, trying to prototype with factories before he had firmware/app figured out—and has since rebuilt with a scrappier freelancer-led network. That course-correction muscle is underrated.

What I like (and what I’ll watch)

Promising

  • Replace vs. dilute is actually a different architecture for consumer ventilation.
  • Sensible constraints (no HEPA choking airflow; sealed dampers to protect your AC).
  • Clear first customers: allergy households, CO₂-meter dads/moms, people with window ACs or weak central HVAC; plus schools/hotels as obvious B2B pilots.

Open questions

  • Onboarding reliability: they’re moving the setup to BLE; I’ll want to see the out-of-box experience be boringly solid.
  • Certifications: UL/FCC/CE/ROHS can be a slog for first-time hardware; timelines slip.
  • Noise vs. CFM: the spec calls for high airflow with sub-40 dB targets; maintaining that in real homes is where many fans die.
  • Cash & cadence: hardware demands working capital and operations rhythm; I’m looking for 100+ paid beta units in the wild with weekly firmware updates and telemetry-driven improvements.

Founder notes (the candid part)

Arjun’s Dell background shows up in the model-based control and the way he thinks about cost curves and attach channels. His startup background shows up in humility: he’ll tell you straight up that he underestimated hardware timelines, wasted money on early ads, and over-trusted factories for prototyping. He’s corrected course—small pilot runs, in-house control of firmware/app, and tighter integration between design and field testing.

If you’re the target user, here’s the “try-it” heuristic

  • You own a CO₂ sensor and routinely see 1,200–2,000+ ppm in bedrooms or home offices.
  • Someone in the home has seasonal allergies, but you still want legit fresh air.
  • Your utility bill makes you flinch in summer, and you’d gladly shift ventilation to smarter hours if a bot handled it.
  • You’re comfortable with a wall core (6") or you’ll accept a window unit to avoid drilling.

If that’s you, Vyana is worth watching for its first production run.

For the builders reading this

A few execution choices I think other hardware founders can steal:

  • Pick a contrarian constraint on purpose. “No HEPA” sounds like heresy until you define the job (air exchange with pollen control) and design around it.
  • Predict, don’t just react. Combining in-home sensors with weather/pollen forecasts turns a dumb timer into a smart scheduler.
  • Seal the idle path. Motorized dampers are the unsexy detail that protects the energy story; customers feel this in their bills.
  • Own your first 100. Tight, telemetry-rich beta cohorts beat glossy marketing every time.

Disclosure

I’m not an investor or advisor to Vyana. I heard about the Austin HW event session and followed up with a longer product/tech debrief. If (when) I get a unit in-home, I’ll update this with measured CO₂/PM curves, noise at different CFMs, and real energy deltas.


TL;DR: Vyana is trying to make fresh air an algorithmic decision, not a manual chore. If they nail onboarding, noise, and certification, “replace-don’t-dilute” could become the default way we ventilate homes.
