Retro's ex-Instagram founders are chasing a smaller social graph

Why it matters

The social opportunity has shifted from replacing Instagram outright to carving out behaviors that scaled feeds handle poorly: private photos, taste curation and cross-network identity.

Nathan Sharp and Ryan Olson's Retro is the clearest founder story inside the crop of social apps TechCrunch highlighted on June 6: two former Instagram team members building against the feed they know best.

The point is not that one startup has found a clean replacement for Instagram, TikTok, X or YouTube. The point is that social is splintering by use case. TechCrunch's visible list names Retro for private photo sharing, Cosmos for visual inspiration and taste, and Indigo, an app from Soapbox Software, for using Mastodon and Bluesky from one interface. Each targets a different frustration with scaled social platforms: audience collapse, low-signal discovery, and the cost of choosing a network before knowing where people will settle.

That makes Retro the useful starting point. Sharp and Olson came out of Instagram, according to TechCrunch, but Retro is built around a narrower premise: photos for friends, not a public performance system. The app lets users pick photos to highlight weekly, create albums, follow others, search profiles, and decide which friends can see more than the most recent month's worth of photos, TechCrunch reported. Those controls matter because they reject the core bargain of the modern feed: post once, optimize for everyone, then live with the context collapse.

The anti-feed is becoming several products

Retro has been on this path for some time. TechCrunch previously covered its collaborative journals in April 2024 and a camera-roll "time travel" feature in December 2025. That timeline is important: Retro is not a new launch riding a backlash cycle. It is part of a longer attempt to rebuild photo sharing around memory, small groups and permission.

Cosmos attacks a different part of the incumbent social stack. TechCrunch describes Cosmos as a "space for inspiration" for creative users, with search by color, keyword or image, collaborative collections, profiles shaped by taste, and shopping tied to a user's style. The comparison point is less Instagram Stories than Pinterest-style discovery, especially as image feeds become harder to separate from AI-generated filler.

Indigo is the most explicit bet on fragmentation. TechCrunch says the Soapbox Software app combines Mastodon and Bluesky in one interface, with a unified timeline, a composer for cross-posting, custom feeds and personalization tools. TechCrunch separately covered Indigo in May under the headline "Indigo brings the open social web to one app". That product logic is different from building the next network. It assumes users will live across protocols and that the client layer can become the control point.

Meta's moat is still the graph

The hard part for Sharp, Olson and other social founders is not shipping a cleaner app. It is persuading people to rebuild the habit loop that incumbents already own. Meta (@Meta) controls Instagram, Facebook and WhatsApp. Google controls YouTube. TikTok owns short-form video attention at global scale. X, for all its volatility, remains a default public conversation layer for many media, finance, politics and tech users.

None of the visible source material establishes user counts, download figures, revenue, funding, retention or valuations for Retro, Cosmos or Indigo. That absence is not a footnote. Consumer social startups often look strongest in product screenshots and weakest in cohort math. Without active-user and retention data, the only verifiable claim is product direction, not breakout adoption.

Still, the direction is consistent. Founders are no longer pitching a single universal town square. They are choosing smaller surfaces where incumbents are structurally awkward. Instagram can add Close Friends, but it still carries the incentives of a performance network. Pinterest can add AI and shopping, but that creates room for a taste-first app to claim higher signal. Bluesky and Mastodon can grow as networks, but that creates demand for clients that make the open social web usable without forcing a user to pick one identity system on day one.

That is the founder opening. Sharp and Olson are not trying to beat Instagram at Instagram's own game, at least based on TechCrunch's description of Retro. They are taking one behavior Instagram helped mainstream - photo sharing - and removing the public-feed pressure around it. Cosmos appears to be doing the same for inspiration. Indigo is doing it for open social navigation.

The next generation of social apps, at least in this visible slice, is not one app. It is a set of founder bets that the old platforms became too broad to serve their most personal behaviors well.
