When WebProNews spoke with Laura Fitton back in October, she had just launched her Twitter app directory called OneForty. We caught up with her again in Austin for SXSW to find out more about the marketplace.

OneForty has 2,500 apps in its current database and knows of at least 7,500 more. Due to this large number of applications, it is nearly impossible for users to know and understand what each one does. According to Fitton, OneForty was created for this reason.

As she explains, users can write reviews for each app and also cluster apps together for specific occupations, lifestyles, and more. For example, a user might create a “toolkit” that includes apps helpful to moms or florists.

In regards to the future of OneForty, Fitton told WPN reporter Abby Johnson that it wants to enable developers to build actual businesses. Some apps are meant only as hobbies and some are meant only for business, but there is also a space in the middle that produces some exciting innovations.

Fitton says, “We’re looking to play that kind of ambassador role between the broader Twitter community and these innovators and give the innovators the tools they need, whether it is collecting donations to keep the service up or whether going full-fledged selling subscriptions [and] building a business out of their hard work and innovation.”

She also offers advice to developers by encouraging them to find their target audience and serve it really well with specific tools.
