Sean Percival, best known for founding Los Angeles tech blog lalawag, in addition to his work as an executive at MySpace, has booted up a new effort--Santa Monica-based Wittlebee, a new, online subscription service for baby supplies. The new effort emerged this week, revealing that it is backed by Science, Inc., the digital business incubator/studio headed by former MySpace CEO Mike Jones. Wittlebee is the third company from Science inc. to launch in the last few weeks, and the second, e-commerce via subscription firm from Science. Wittlebee offers up subscription packages that delivers basics like onesies, t-shirts, socks, leggings and other products to parents, starting at $39.99 a month. Percival shut Lalawag--run with wife Laurie Pervical--in 2010, in part because of the birth of Percival's baby and his work serving as VP of Online Marketing for MySpace under Jones. Last week, Science revealed it was backing another, subscription e-commerce effort, MeUndies, in addition to backing another startup--Eventup--run by Tony Adam, another active Los Angeles technology figure.
