A shadow is falling over Silicon Valley, and some of its most promising startups are crumbling under the pressure.

Just this Wednesday, high flying microbiome startup uBiome announced it was filing for bankruptcy after months of controversy and federal investigations into its testing procedures and billing practices.

The startup, which claimed to test users’ stool samples using cutting edge medical technology, had raised more than $US104 million in private venture capital from top firms like 8VC and Andreessen Horowitz. Before filing Chapter 11 on Wednesday, the buzzy startup was worth more than $US600 million, according to Pitchbook data.
