Calvin Appby Nick Sonnenberg
Nick Sonnenberg is a former Wall Street high-frequency trader who gave up a seven-figure salary to launch Calvin App, a productivity tool that helps users store 'someday' events and simplifies scheduling by showing overlapping free time without exposing full calendar details. Launched in public beta with ~400 monthly active users after being featured at Twitter's developer conference for innovative API integration, Calvin is pursuing a $750K funding round at a $6-8M pre-money valuation with plans to monetize through affiliate partnerships and brand integrations.
