Form 144 regulatory

"The filing is a Form 144 notice regarding proposed and recent sales"

Form 144 is a document that investors must file with the government when they plan to sell a large number of shares of a company's stock. It helps ensure transparency so everyone knows how many shares are being sold and when, which can impact the stock's price.

Founder Shares market

"Securities To Be Sold section lists 'Founder Shares' dated 11/21/2023"

Founder shares are the ownership stakes given to the people who start a company, often with extra voting power or protections compared with ordinary shares. For investors, they matter because founders’ control and incentives influence decisions about strategy, hiring, and whether the company sells or stays independent — like a family that keeps majority voting rights in a household decision. High founder ownership can mean stable leadership but also a risk that outside shareholders have less influence.
