Oneforty

Oneforty was a Twitter application marketplace and app store founded by Laura Fitton in 2009, letting users discover, review, and purchase third-party apps and services built on the Twitter API. It raised roughly $1.9M (Flybridge Capital, Javelin Venture Partners, and angels including Dave McClure) and grew to thousands of listed apps before being acquired by HubSpot in 2011. The company is defunct — the oneforty.com domain now 301-redirects to hubspot.com and exposes no developer surface, API, documentation, or SDKs. Retained in the network as a historical portfolio-lead record only.

Oneforty is profiled on the APIs.io network. Tagged areas include Company, twitter, App Marketplace, Social-Media, and Developer Ecosystem.
