Many firms first look to open source to lower the costs of their non-competitive technology, like back-office systems. This talk will show how open-sourcing software that is critical to an organization's competitive edge can create value by exploiting the network effects of collaborative development. Jared Broad, CEO of QuantConnect, will explore why his company open-sourced LEAN, its radically open source algorithmic trading platform, and how QuantConnect has attracted over 60,000 engineers with its professional-grade backtesting and live-trading system used by banks and funds globally.
