Twitter CEO Dick Costolo Tells Developers to “Move Up the Value Chain” (Video)
Twitter CEO Dick Costolo shared details and perspectives about Twitter usage, developer relations and monetization in an interview with Walt Mossberg today at D9. He also introduced new photo and search products.
Context & Ripple Effects
This lands mid-arc for Costolo, who five months earlier told the Los Angeles Times he was determined to get the last laugh on Twitter's doubters. At D9 he paired that confidence with product moves: confirmed launches of Twitter's own photo-sharing service and a completely rebuilt search experience with photos folded in.
The 'move up the value chain' advice to developers is the tell — it comes alongside reports, unconfirmed, that Twitter is in sub-$10 million talks for Y Combinator-backed keyword bidder AdGrok, likely an acqui-hire aimed at its ad stack. Reuters' pickup of the same interview adds the one hard number available: Costolo says 80 percent of advertisers renew.
First-order effects
- Developers whose clients and services duplicate Twitter's core experience — especially third-party photo hosting built on the API — now compete against Twitter's first-party photo and search products rather than extending them.
Second-order effects
- If the AdGrok deal closes as reported, keyword-bidding capability moves in-house, tightening Twitter's control of its own advertising pipeline instead of leaving it to intermediaries.
Third-order effects
- The pattern points toward platform owners commoditizing the app layers built on top of them: APIs become funnels for first-party features, and independent developers survive only in categories the host declines to enter.
The trend: Consumer platforms are shifting from open API ecosystems toward vertically integrated feature stacks, forcing the developer layer to migrate upmarket or get absorbed.
