The grip Twitter, now called X, has on the market may be stronger than some believed. Unfortunately, that’s led to the first casualty among Twitter alternatives, as the startup Pebble (formerly T2), is shutting down. The would-be X rival had grown a small but engaged community on its microblogging service that aimed to dupe Twitter’s features, from its verification systems to functionality like DMs. But the company says they’ve run out of time to make Pebble happen — the app maxed out at 3,000 daily active users, out of 20,000 registered users. That daily user figure fell to 1,000 daily users following its rebranding from T2.

In part, the sizable competition coming from other Twitter rivals was to blame, says co-founder and CEO Gabor Cselle, who had exits to Google and Twitter prior to starting Pebble.
