Retro Secures $21M Series A to Expand Friend‑Focused Photo Sharing

Retro, a photo‑sharing app that prioritizes sharing among friends, has closed a Series A round that raised more than $21 million. The company was founded by former Instagram employees who aim to differentiate the platform by focusing on close‑friend networks rather than broad public audiences. The funding round brings the total capital raised to over $21 million, positioning Retro to scale its infrastructure, develop new features, and expand its user base. Investors view the niche approach as a way to capture a segment of the social‑media market that values privacy and intimacy in photo sharing.
