The problem

Launching a token takes an afternoon. Verifying the team behind it does not, and buyers rarely have the time. Launch platforms want to surface real founders and filter out bad actors, but hand-vetting every team does not scale.

The approach

Ethos turns founder reputation into a portable score, computed from reviews, ETH staked through vouches, and verification. Put it on the page where money moves and reputable founders get distribution, backers get a first-glance read, and the score follows the founder from one launch to the next.

On Vibestarter, escrow releases over time and backers can challenge.

Legion and Vibestarter

Legion has run 30+ token sales and powers Kraken Launch. Founder scores appear on its sales pages, feed into the Legion score, and Human Verified users get a badge and tiered access.

Vibestarter shows the founder’s Ethos score on every raise page, holds funds in escrow released in monthly tranches, and gives backers a 72-hour window to challenge each release.
