In my experience, as a small business, it's almost impossible to convince any large company to use your product no matter what it is or how good it is; it doesn't matter if it's self-hosted, SaaS, enterprise or open source... The problem is that you're a small shrimp and nobody who has any power in the big company knows who you are, they don't trust you. Not to mention that big company directors and senior employees are often best buds with their current SaaS software providers and so there will always be insiders who will object whenever someone proposes to switch providers to your solution because they don't want to hurt their buddies... And they love to keep that revolving door open for themselves so that they can switch jobs to the SaaS provider's company and get an even bigger salary than they're getting now (as thanks for helping the provider to keep the contract all these years by repeatedly pushing for platform lock-in, even though it was against the previous company's interest). Also, most big tech companies have enough money coming in from their market monopoly that they really don't care about optimizing stuff. Nobody cares that your solution is 10x simpler and 10x more efficient in terms of computational resources. It's a marginal cost to them.
