MongoDB Inc did have its valuation reduced by some institutional investors. Hard to say whether that was premature or what the impetus was behind their decision. MongoDB is an incredibly well-adopted product that has gotten considerably more capable over the years. I would argue they've had good success with this business model, as building a $1.6B business is a huge accomplishment whether you've got an OSS business model or not.
It would be fair to ask whether they've done the balancing act as well as they might have. They've certainly knocked OSS adoption out of the park. On the other hand, I've heard anecdotally that they waited a long time before introducing enterprise features.
Regardless, I view MongoDB Inc. as a big - and still growing - success, and consider much of what they've accomplished to be worthy of emulation.
"I don't know much about one of our signifcant competitors' business model." doesn't sound like something you would want to hear from someone just announcing their business model.
In the same vain, the next to be slashed will probably be Docker.
what it probably won't do is make plenty of money for investors.
MongoDB offers a commercial version of their product with enterprise features (encryption at rest, LDAP auth, etc) and support - MongoDB Enterprise.
Additionally they also offer managed, cloud hosted MongoDB deployments - MongoDB Atlas.
Over the last few years the valuation of MongoDB, Inc. has been slashed by institutional investors such as Fidelity and BlackRock. While they haven't had mass layoffs or some other negative corporate event, they have clearly had some difficulty making their (and apparently your) business model work.
Do you agree that this is a fair comparison? And what do you makes CockroachLabs more likely to succeed with this business model than MongoDB?
