Sidekick, a productivity web browser, sold a lifetime deal on AppSumo. After the Sidekick team was acqui-hired by Perplexity (reported by The Information), the browser was sunset on August 3, 2025, and the meetsidekick.com domain now redirects to the Comet browser by Perplexity. An earlier end-of-2024 shutdown notice was disputed at the time; the actual sunset followed the acquisition.
