No. Your existing investors (LPs) are not automatically part of Meridian
Some of your investors may choose to join Meridian independently to explore new investment opportunities or manage their existing portfolios. When they do, they’ll continue to be part of your investor network, but they may also see other opportunities that align with their stated preferences.
Meridian only introduces investors to new opportunities after they’ve opted in and created a profile on the Meridian platform. AngelList does not automatically market new opportunities to your investors without their explicit action.
