Phil Jacobsen and Rob Witman are developing dual screen technology designed to link apps and games between mobile phones and TVs. But the leaders of Splitmo also are safe crackers – and achievement that won them six months of free rent in the @Main co-working space.

In the basement of the recently @Main is a huge bank vault – simply labeled The Vault.

Management issued a challenge to its tenants – crack the safe’s combination and win six months of free rent.

In a recently published video at YouTube, Jacobsen and Witman explain how they cracked the safe – and helped their cash flow.

Splitmo, which launched in 2012, is creating mobile apps that “leverage dual screen technologies such as Apple T,” the firm says.

For example, its Air Show app “lets consumers spontaneously share their iPhone/iPad gallery images on an HDTV screen while using the handheld as an on-the-fly preview and editing screen.”

Their “Poker Night TV ” is a play in the social gaming space.

Says Splitmo: “Poker Night TV leverages your big screen TV for a 21st Century take on Texas Hold’em Poker. Using an Apple TV and AirPlay, your TV shows off the common cards, pot and player positions while individual players’ cards are kept hidden on their devices. Players can toss their bets or their cards in on their own device while the rest of the group keeps up with the action on the TV. Even without an Apple TV, players can use their devices alone to monitor the action or connect an extra iPad as the virtual table.”

The app, which launched in July, is available at the iTunes store.

@Main is part of American Underground, which operates its primary location at the American Tobacco Historic District. The Underground also is expanding to Raleigh.

The American Underground and the American Tobacco Historic District are part of Capitol Broadcasting, the parent firm of WRALTechWire.
