Last time Spark raised money, it set out to raise $10,000 and got $567,000, via a nifty pitch on Kickstarter. This time, venture capitalists including Lion Wells Capital and O’Reilly AlphaTech Ventures have put up $4.9 million in a Series A round. Spark is another one of the many connectors for the Internet of Things. It helps people add Wi-Fi to whatever they are building with a tiny piece of open source hardware and an API. Spark also wants to expand beyond Wi-Fi, said CEO Zach Supalla.
