Connecticut has invested $450,000 in three tech startups, including a Simsbury designer of an online education-search platform for combat veterans.

Connecticut Innovations Inc. said each received $150,000 from its Pre-Seed Fund to go with matching funds from private investors.

Simsbury’s C2C LLC, doing business as Combat2Career; Grey Wall Software LLC, of New Haven; and Stone Creek Entertainment Inc., of Ridgefield.

Year-old Combat2Career, launched by a pair of UConn business-school grads, enables military veterans to search for and apply to higher education programs that match their skills and interests.

Grey Wall has developed a web and mobile software solution that promotes team collaboration between first responders and other emergency authorities during severe weather, accidents and power outages.

Stone Creek designs and publishes mobile and social network games geared to teen girls and women.

One of its three games ­– Karizmac Luminous – is ranked by iTunes as one of the top 100 in many countries. Through that game, users discover what their decisions say about them and how they compare to famous female leaders.
