Chef was sold for scrap earlier this month. https://news.ycombinator.com/item?id=24407323

Puppet took $40M in debt in July. I don't think they are sellable because they had a high valuation and now a ton of debt, while the product is on a strong downward trend replaced by ansible/terraform. My guess is they get enough revenues from a few large customers to sustain a small-medium company.
