Project Infinite to Smart Sync: the rebrand that gated a marquee feature
Project Infinite announced April 2016; launched as Smart Sync January 2017
Dropbox demoed 'Project Infinite' in 2016 as a way to see all cloud files on the desktop without using disk space, then shipped it in January 2017 rebranded as 'Smart Sync' — but restricted it to paying Business and Professional tiers rather than the free product its demo had implied.
What happened
In April 2016 Dropbox unveiled Project Infinite, a much-praised demo showing every file in a user's account appearing in the desktop file system as a placeholder that took up virtually no local space until opened — solving the perennial problem of accounts larger than a laptop's disk.
When the feature shipped in January 2017 it was rebranded as Smart Sync and rolled out through an early-access program limited to Dropbox Business, with availability for the paid Professional tier. The marquee capability that the Project Infinite demo had made everyone want was, in practice, a paid-tier feature rather than something free or Plus users could use. The rename itself caused minor confusion, but the gating drew the sharper reaction: a widely promoted technical breakthrough turned out to be an upsell lever.
Smart Sync went on to become a long-lived part of Dropbox's paid offering, but its debut set a template users would see repeatedly — desirable capabilities reserved for higher tiers, with the free and entry-level experience kept comparatively thin.
Impact
The Project Infinite-to-Smart Sync arc illustrated how Dropbox converts buzzy demos into paid-tier differentiators: the feature everyone wanted from the 2016 demo arrived in 2017 behind a Business/Professional paywall. It fed ongoing frustration that Dropbox's most compelling capabilities were steered toward upselling rather than improving the core product most users actually had, a theme echoed later in device limits and storage changes.
