Few entrepreneurs can say they’ve grown their business into multi-million dollar enterprises in just a couple years. Far fewer can say they’ve done so all before even graduating high school.

Jaylen Bledsoe, 15, of Hazelwood, Mo., however, is just that rare breed of high school sophomore. He started his own tech company that specializes in web design and other IT services, Bledsoe Technologies, when he was just 13 years old and worked to expand it into a global enterprise now worth around $3.5 million, Fox 2 in St. Louis reports. The local news station followed up with Bledsoe on Monday after first interviewing the teen back in March 2012. Since that first interview, Bledsoe has grown his company from two workers to about 150 contracted employees in order to meet demand.
