You may have an MVP, I would now find a customer to be the first beta user. This will be someone who currently has enterprise search, but is really frustrated with it. They'll give you insight as to what they need, that their solution currently doesn't provide. You'll incorporate their feedback and rev the product.

Once you have made them stark raving happy, they'll be telling their friends and colleagues about it. They may give you a lead on customer number two.

Good luck!
