How Film Live Streaming Hit 10k MRR in 31 Days using Signalwire

When David Plappert set out to launch Film Live Streaming, he wasn’t starting with a telecom background—he was a developer and cloud systems admin who wanted to solve a practical problem: helping churches, governments, and other organizations share their live video streams over the phone.

With just a Google Form and a simple Ruby app, David’s idea took off. In the first 31 days, Film Live Streaming went from zero to $10,000/month in recurring revenue.

The secret? Building on SignalWire.

Making Telephony Developer-Friendly

David didn’t want to spend weeks managing SIP, SBCs, and carrier interop. With SignalWire’s programmable Voice APIs and built-in telephony infrastructure, he didn’t have to. Instead, he focused on writing clean application logic—while SignalWire handled high-volume call routing and audio streaming.

“From day one, we’ve used our Ruby app to manage 10,000+ calls per second, and SignalWire has handled it without issue.”
