This is 100% true - but that is their business model. And I cannot call it age discrimination since they are VC not an employer. Older founders are more likely to make a profitable business (lifestyle business) but less likely to create a unicorn type hot start up. In other words, if one is experienced then one can make profitable business (lifestyle business) even if the idea is bad.
