A bit over a week ago Intelligent Investor posted a research writeup on Biome - titled "Biome's balancing act - This probiotic startup is enjoying strong demand, but it's an uphill battle from here"
It's behind their paywall but ended not with a "Buy", "Sell" or "Hold" rating but rather with a "We'll be watching Biome from the sidelines"
Some of what they covered in the writeup was discussed in their latest Intelligent Investor : Stock Take Podcast which is also available on Youtube

The Biome discussion starts at around 31:40
