Looking for an Early Adopter to test my product [ I will not promote ]

Hello everyone! I coded an MVP and it is “fully” functional, however i need a real life case to test it. I have been going around asking for startups to test it but they are either too busy or “uninterested”. My product solves a big pain that big companies (of virtually any kind of business field, as long as they have more than ~15 employees) have when it comes to internal organization, but getting a big company to test this would be impossible without prior success with a small one (I guess). Do you guys have any suggestions? Thanks in advance!
