Bending Spoons has recently been buying aging SaaS companies that have established PMF and customers and decent brands (Evernote, Komoot, WeTransfer, Meetup).
I guess it's mostly a private equity play—usually after being acquired by BS, prices go up, paywalls go everywhere, companies get "more efficient" (aka layoffs) and the product stops evolving.
I wish there was a better outcome for beloved brands with good products that won't experience any more hypergrowth.
