Friend-focused photo-sharing app Retro snags $21M

Retro, the friend-focused photo-sharing app built by former Instagram product engineers Nathan Sharp and Ryan Olson, has raised north of $21 million in Series A funding, according to an SEC filing.

The fundraise is a testament to the enduring need for social apps that connect people with one another more directly, instead of through personalized algorithms filled with creator content and now, often, AI slop.
