We are able to be far more responsive than enterprise companies. Consider a service like 'Salesforce', a massive, popular, very functional product. It can be used for many purposes, which is great, and some organisations use it for advocacy.
What happens however, when your funder suddenly changes its reporting mechanism from an annual word document, to the bi-annual 'Data Exchange', or out-of-the-blue asks you to provide a one-off report aggregating all your data for the last five years, in a new way, due in two weeks time?
Advocacy, is itself, too specialised and niche to receive the support you need from such a large vendor like Salesforce, however 1024 is able to provide that support to you because your niche, is our niche.
