02  The gapthink2earn — pre-seed 2026

A $90B sensor market runs on hardware you can’t open and data you don’t own. Both just became fixable.

$450/yr

what a user spends on wearables

closed firmware, vendor app only — Apple, Oura, Whoop, Abbott, Dexcom

what they pay you for your data

biometric data is aggregated, siloed, and sold — the wearer captures none of it

−90%

optical sensor cost since 2020

research-grade optics now fit a <$500 consumer device — and onchain rails can pay contributors

WHY NOW

Cheap optics + 500M wearable users + zero open alternatives. The unlock isn’t a new sensor — it’s who owns the data it produces.

03  What we’ve builtthink2earn — pre-seed 2026

The only open biosensor that pays its wearer. Shipped.

Shipped

Hardware — v2 in production

Light-based headband & armband. 4 circuit boards manufactured and tested. Built with Vanderbilt’s Bowden Lab.

Live

Software — upload, train, get paid

Web app for raw sensor ingestion, model training, and onchain reward claims.

Published

Dataset — first of its kind

Open paired light–glucose data with reproducible ML pipelines. First beachhead: glucose-trend prediction.

ALSO LIVE

Auth, payments & agent rails run in production at chat.think2earn.com — the data marketplace reuses them at zero marginal build cost.

04  How it worksthink2earn — pre-seed 2026

Data flows to researchers. Money flows back to wearers.

TODAY: your data → their cloud → their revenue. You get $0.

01 — WEARER

Wears the device, runs local health models

LOCAL · SOVEREIGN

ZK PROOF
02 — SMART CONTRACT

Auditable protocol meters access & routes payment

OPEN-SOURCE · VERIFIABLE

PAYS USDC
03 — RESEARCHER

Labs & AI teams pay for verified, anonymized insight

NEVER RAW DATA

Open

Schematics & firmware on GitHub. Anyone can build, improve, audit. <$500/unit.

Yours

Data stays on-device unless shared. When you share, you earn — paid onchain.

Proven

Every payout cryptographically verifiable — zero-knowledge ML, onchain receipts.

THE MOAT

Open hardware, private dataset. Incumbents can’t copy without killing sensor revenue. Forks start at zero. We compound per unit shipped.

REVENUE 01

Device sales

D2C at $400–600. One-time purchase, no subscription.

REVENUE 02

Dataset licensing

Universities & labs pay USDC for verified, paired biometric data.

REVENUE 03

Marketplace fees

Take rate on researcher ↔ contributor exchanges as the network opens.

FLYWHEEL

Device + data revenue → 30% of gross profit to onchain buyback → stronger token → bigger contributor rewards → more devices, more data.

10  Tokenthink2earn — pre-seed 2026

USDC pays the bills. Profit buys the token. Emissions can never outrun the buyback.

01 REVENUE

Hardware + data licensing, paid in USDC by default — or stake $T2E instead (dual rails).

02 BUYBACK

30% of gross profit → public onchain contract, TWAP buys — no discretion, no front-running. Bought $T2E → protocol-owned liquidity until a depth target, then 100% burn.

03 EMISSIONS

Pegged to the buyback: at most $0.75 minted per $1.00 repurchased — supply contracts by construction, no assumptions required.

04 ACCESS

Staked $T2E = a fixed daily API allowance — dataset queries, model access, agent tools. Using the product means buying and holding it.

05 SINKS

Pay in $T2E → 15% discount, tokens burned · quality bonds on data uploads — junk gets slashed.

PHASE 01 ● LIVE

Contributor tokens unemitted at year 8 are burned — the pool is a ceiling, not a schedule. No hidden overhang.

Investors & team: 2-yr cliff, 4-yr vest. Insiders 30% total. Staked $T2E governs emission splits, bounties, treasury.

11  The askthink2earn — pre-seed 2026

$150K turns a shipped device into a validated dataset company.

$3M SAFE · 5 MONTHS · 2 MILESTONES · UNLOCKS SEED

$50K

PHASE 1 — M 1–2

Ship the platform

  • — 50 open-hardware units manufactured
  • — Data ingestion + ML training pipeline
  • — Payout rails: Base L2, x402, EIP-3009

$100K

PHASE 2 — M 3–5

Validate first vertical

  • — 100-person glucose-trend trial (CGM + finger-prick ground truth)
  • — Leave-one-subject-out cross-validation
  • — Lock the model. Prove the loop.

Seed

OUTCOME — M 6+

Open dataset + working loop

  • — First-of-kind paired biometric dataset
  • — Validated glucose-trend model in production
  • — Clinical evidence pipeline for EU MDR

DE-RISKED

Kill criterion pre-named: if glucose-trend accuracy misses the bar, the same hardware pivots to cognitive load — the dataset and platform survive the pivot. Launches as wellness & research device (no FDA/MDR gate). $35k in build credits already offsets infra.

WHAT YOU FUND

An open biosensor platform, a first-of-kind paired dataset, and the loop proof that unlocks every adjacent vertical. Swiss association (Zug) = clean token pathway.
