$1,100 · 3 weeks · 25 prospects
Prove that heavy dictation users will put $100 down for silent speech input rather than settle for whispering into a microphone, for $1,100 in 3 weeks.
Riskiest assumption · People who dictate to assistants all day but cannot speak aloud at their desks will pay for a silent-speech wristband instead of settling for whispering into a microphone or falling back to typing - the operator's and the card's own core objection.
1Focus group: who and where
A developer, writer, or analyst who dictates to AI assistants an hour or more a day using Talon, Superwhisper, or Wispr Flow, works in an open office or shared space, and either has RSI or simply cannot talk out loud where they sit.
where to find 25 · The Talon Voice community Slack (thousands of hands-free coders, many dictating all day because of RSI), the r/RSI subreddit, a Show HN post on Hacker News, and a sponsored placement in the Console dev-tools newsletter that these users already read.
2Sell first, build later
A first-run Innervox band at the $349 founders price: silent dictation into any assistant via keyboard emulation, beta units to the first 300 reservers, with measured decoding accuracy numbers published before anyone is charged the balance.
the ask · $349 per unit at the founders price; $100 refundable reservation charged today.
a real yes · A real yes is the $100 card charge clearing at checkout; Hacker News karma, free waitlist signups, and enthusiasm from accessibility forums without payment do not count.
3Small experiments
The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.
1. Whisper baseline interviews
$300 · 10 days
Recruit 15 heavy dictation users from the Talon Slack and r/RSI with a $20 gift card, and map exactly where dictation fails them: hours per day dictated, rooms where they cannot speak, and specifically whether they tried whispering into Superwhisper or Wispr Flow at their desk and kept doing it or gave it up. This attacks the killer alternative head on before any money is spent on marketing.
keep going if · 9 of 15 dictate 1+ hour daily, tried whispering or a desk mic in shared space, and abandoned it for accuracy or social reasons
2. Paid reservation smoke test
$800 · 14 days
Build a landing page with an honest concept video (a person mouthing words, text appearing in a chat window, clearly labeled as a rendering) and a $100 refundable reservation for a first-run unit at a $349 founders price. Post to Show HN, the Talon Slack, and r/RSI, with a $250 paid boost; run half of traffic to a free waitlist and half to the $100 reservation so interest and money are measured separately.
keep going if · 15 paid $100 reservations from roughly 1,500 qualified visitors in 14 days, with the reservation arm converting at 25%+ of the waitlist arm's rate
4Collect a deposit up front
Tesla took $1,000 refundable reservations for the Model 3 and $100 for the Cybertruck before building either: the deposit is the measurement, not the revenue.
$100
per prospect, refundable
how · A $100 refundable reservation taken by card at checkout on the pre-order page - the right instrument for a direct-sold consumer device with no procurement in the way; the buyer checks out alone and the card charge is the measurement. set up: Stripe Checkout ↗
what it reserves · One of the first 300 beta units at the $349 founders price, credited against the balance at shipping.
refund · Refundable with one click any time before the unit ships, and offered again explicitly when accuracy numbers are published before the balance is charged.
target · 15 paid reservations from roughly 1,500 qualified visitors within 30 days
before taking money · Market the device strictly as a productivity input and make no medical, accessibility, or diagnostic claims before FDA counsel reviews the speech-accessibility indication.
Go: build it if
15+ paid $100 reservations and 9 of 15 interviewees who abandoned whisper or desk-mic dictation in shared spaces: the behavior gap is real and funded, start the sensor prototype.
Kill: stop if
Fewer than 5 reservations from 1,500+ visitors, or most interviewees report whispering into a mic already works for them at their desk: the stated risk that whispering beats the band stands, stop.
5 Scripts to run itoutreach message, landing copy, deposit terms · click to open
outreach message
You dictate through Talon because typing hurts or is too slow, and I'd bet there are rooms where you can't dictate at all. I'm building a wristband that reads the muscle signals of silent speech so you can talk to your assistant without making a sound. No device exists yet; before building it I'm testing whether it actually beats whispering into a mic. Could you spare 20 minutes this week to tell me exactly where dictation fails you? $20 gift card for the time.
landing page
Talk to your AI silently. No sound, full speed. $100 refundable reservation holds a first-run unit at the $349 founders price. Reserve unit 1 of 300 - refund any time before it ships.
deposit terms
Your $100 reserves one of the first 300 units at the $349 founders price and is credited against the balance at shipping. It is fully refundable with one click at any time before your unit ships. We will publish measured decoding accuracy before charging the balance; if the numbers disappoint you, take the refund.

The idea in full
- What
- Innervox builds a consumer wearable that reads surface EMG signals from subvocalized speech, letting people talk to AI assistants silently at conversational speed - in meetings, open offices, or public spaces. It pairs a custom sensor array with on-device decoding models and sells direct online, while pursuing FDA clearance for a speech-accessibility indication that both expands the market and raises the bar for followers. This is a new input category: the keyboard of the assistant era.
- Why now
- MindPortal chased thought-to-language and was gone by 2021, when this cluster added only 7 new companies; 2025 added 57, and S26 investors are funding neural-compute bets as exotic as Parasma's brain-cell training. Decoding models and capital appetite have both caught up to the interface problem MindPortal hit too early.
- Wedge: first customer and entry point
- Power users who dictate to coding and chat assistants all day but cannot speak aloud at their desks; the accessibility community as the first loud, organic advocates.
- Path to 100x
- If silent speech becomes a default way to address AI assistants, the winner defines a new device category inside the $10-100B wearables market and sells an attach-rate product to hundreds of millions of assistant subscribers. Distribution compounds: bundling deals with assistant platforms and an FDA-cleared accessibility indication make Innervox the default SKU on the shelves that matter, a position a second entrant cannot buy back cheaply.
- Ceiling
- If decoding accuracy plateaus for average users, the product stays a valuable but sub-$1B accessibility device.
- Closest real companies, as the generator saw them
- MindPortal (graveyard) went after brain signals directly and died on decoding quality; Parasma grows neurons for compute, not interfaces; Miso Labs and KugelAudio build voice models that still require audible speech.
- Main risk
- Non-invasive EMG never reaches word-error rates that beat simply whispering into a microphone for enough of the population.
Five judges
Each judge scores every idea in the catalog with a named rubric; the venture judge decides whether a card is shown at all (4-5 is venture-grade).
Venture investor
4/5
Defining the input device for hundreds of millions of assistant users inside a $10-100B wearables market is exactly the power-law bet.
Bootstrapper
1/5
Custom EMG sensor arrays plus an FDA clearance path is hardware and regulation stacked on a hype-priced wearable bet.
Operator
1/5
This asks consumers to adopt an entirely new input behavior against whispering into a microphone, with no budget owner anywhere.
Technologist
4/5
Surface EMG subvocal decoding with a custom sensor array is exactly the deep sensor-plus-model problem where expertise compounds, MindPortal notwithstanding.
Risk
1/5
Single unlicensed consumer SKU chasing FDA clearance, with MindPortal dead in the same graveyard and only better decoding models offered as the difference.
trends
2/5
The why-now is 'capital appetite caught up since MindPortal died' - no dated 2025-2026 mechanism showing EMG decoding actually crossed the usable threshold.
