Carta CEO says startup is investigating email about share sale

The chief executive officer of Carta Inc. said the startup was investigating customer allegations that it misused their data while also accusing the customer of “calling for the end of” the financial software company.

The tiff began on Friday when Karri Saarinen, CEO of software startup Linear Orbit Inc. and a customer, posted a complaint that Carta had used its knowledge of the company’s investors to approach one of them via email about selling Linear shares on the secondary market.
