Guillermo Söhnlein has been unexpectedly thrust into the limelight in the wake of the Titan submersible tragedy.

The cofounder of OceanGate Expeditions has been grappling with questions about the company's ill-fated trip to the Titanic shipwreck on June 18, which killed five people, including former colleague and friend Stockton Rush.

The sub is thought to have imploded within hours of its descent, raising concerns about OceanGate's approach to innovation and safety.

But OceanGate is not Söhnlein's only venture. The businessman's latest — and possibly grandest — endeavor is to send 1,000 humans to live in Venus' atmosphere by 2050. Söhnlein hasn't let the recent events dampen his ambition and claims humanity needs to continue pushing the limits of innovation.
