Tsumobi

Messaging.

Mobile applications have so far been nightmares to implement. It's often hard to gain adoption due to complicated installs and near impossible to get users to upgrade their version once the product has shipped. Tsumobi hopes to solve this problem by creating their own language. The new language will sit on top of J2ME and process applications downloaded (via URL) for Tsumobi enabled sites. This means that developers will be able to change Tsumobi applications on the fly and have Tsumobi enabled phones automatically get the updates just by visiting a link.

Vastrm

Mass customized active apparel. We are building a full turn key…

Vastrm Fashion™ (pronounced vas' trum) Vastrm was started to solve a basic problem: Shirts that don’t fit well! Mass produced shirts were meant to accommodate a wide variety of body types with one standard size, and different brands have different sizing standards, making shopping difficult--many men must shop in 4 - 5 different stores before finding a shirt that actually fits! By providing a home try on program and giving the ability to make custom fit adjustments to all of their apparel, Vastrm allows its customers to finally hone in on and find the perfect fit for their unique body types. Tang came up with the idea for Vastrm, which is a Sanskrit word for cloth, when a customer told him he had purchased a perfect shirt in Italy and has never been able to find the same fit again. He was considering flying back to Italy to track the shirt maker down, but Jonathan managed to adjust Vastrm shirts to the same fit.
