The Internet lacks a protocol for money. Lightspark is building the tools and services to make it happen. Lightspark builds enterprise-ready infrastructure for open payments for the Internet at scale using the Lightning Network. An always-on, low-cost, universal payment network will completely transform how money is moved, enabling businesses and developers to transform existing solutions and build new financial systems, services, and processes accessible to everyone, transcending geographical restraints. Lightspark is headquartered in Los Angeles, California, but serves the world.

At Lightspark, our goal is to build meaningful payment infrastructure by building upon and extending the capabilities and utility of Bitcoin. We are starting by diving deep into the Lightning network.
