Scrubline

DM 40 people who posted in Fishbowl, r/ChatGPTPro or Blind about using personal AI on work data; book 15 twenty-minute calls. Walk each through a 90-second screen recording of masking and unmasking a client memo, then ask for a $39 refundable pre-order on the spot via a checkout link. The founder runs every call and logs who pays, who stalls, and the exact objection.

Build a Figma click-through of the full loop: user pastes a client email, sees the masked version, gets the model reply, sees it unmasked. Put 10 of the interviewees through it unprompted and watch where they hesitate or stop trusting the reversal. This tests the second killer: whether a masked answer still reads naturally enough to use.

One-page site with the demo recording, the $20/month list price, and a $39 refundable pre-order that locks $10/month for the first year. Drive traffic with a Show HN post, two honest posts in r/ChatGPTPro and r/consulting, and $500 of Reddit ads targeted at those subreddits. Count visitors and completed checkouts, not email signups.
