The problem

Traders size risk on vibes, not biology.

Risk appetite is invisible

Your tolerance for loss shifts day to day. No trading tool measures it.

Losses land harder some days

How much a loss stings depends on the state you walk in with.

Every tool reads the market

Terminals, bots and dashboards model prices. None of them model the trader.

The product

Meet the Wank-Bot: sample in, position out.

  1. 01

    Deposit

    A discreet dock collects a full ejaculate sample. Pre-ejaculate is rejected at intake.

  2. 02

    Assay

    An on-board sensor measures the sample's electrolyte ratio.

  3. 03

    Score

    The model turns that ratio into a daily Vitality Score from 0 to 100.

  4. 04

    Bet

    The agent sets today's risk tier and places positions on Polymarket.

Why now

Three curves just crossed.

  1. 01

    Prediction markets went mainstream

    Polymarket and its peers now list markets on nearly everything, around the clock.

  2. 02

    At-home semen testing already exists

    Consumer kits already read sperm metrics at home. We read a different signal: electrolytes.

  3. 03

    AI agents can trade on their own

    Agents can research, size and place positions with no human in the loop.
