Believe me, I've wasted years filling out forms and proposals for investors who only want a sure profit. There's nothing you can do when the fear is on the other side.
The only need for any kind of investors in this case is really due to scaling as time goes, both in regards to infrastructure and employees.
Truth be told, the Sales or Business Development in this case is something that is key in order to break the ice in terms of B2B so that it would get others potentially interested in trying it out and using it.
Believe me, as European, too much bureaucracy and administration is something that is killing industry here.
With that said, I am open to any financing outside of Europe that invests in European startups/companies.
London has decent investors and while they are not as risk-taking as SF ones, they are still quite reasonable.
EU investors, with some tiny exceptions, are terrible in that regard.
