Now this probably is not the most appropriate course of action for you. We initially started as a proof of concept for a branch of a large state owned company. If it’s small enough and doesn’t require too much spending or too much involvement, you can probably avoid the RFP process. But you need to know someone in charge inside, ideally more than one. You can try cold calling or meeting them in a conference but it is easier if you can use a network. If someone else in their industry or their company or maybe a well expert or industry researchers can vouch for you.
Also since it’s a potential ML project, if it’s a public organisation, you may be able to access the data though other means either because it is already public or by simply requesting it. In some jurisdictions, you may request data from public institutions. Once you have the data, you can build you proof of concept and pitch it to the organisation or someone you could use to network your way in.
