TECH CRUNCH - Artifact, the news app by Instagram's co-founders, unexpectedly shuts down due to challenges in catching up with the competition, struggling to expand its user base globally, and facing stiff competition in the news aggregation market. Despite positive feedback, the app experienced a decline in downloads after its launch, with a core community sustaining its activity. Competition from news aggregators like SmartNews and changing news consumption habits impacted Artifact's growth. The app's expansion into various features, potential confusion about its identity, and limited international traction contributed to its closure, highlighting the complexities of the evolving news app landscape.
