About 47Hz
Fast, free event discovery for founders, operators, investors, and builders.
What is 47Hz?
47Hz aggregates professional events from Meetup, Eventbrite, Luma, and other sources across the US and Canada. The goal is simple: help people find the rooms where useful professional connections actually happen.
Why 47Hz?
The name points to frequency: the signal, rhythm, and cadence of a city's professional community. 47Hz is built for people who want the right event without wading through noisy feeds or paywalled listings.
