Without knowing what business you are in, $10/month/seat sounds _way_ to cheap. You are working with businesses here, not consumers.
At this price point you would have to sell about a 1000 seats just to pay for yourself and your co-founder. If you want to bootstrap and hire 4-6 people, you would need to sell a whole lot more.
If you can really 'automate pretty much any business process' as you claim, than your product is worth much, much more than you are currently charging.
See if you can sell it at $1000/month/seat. Yes, sales will be twice as hard, but you'll need 2 orders of magnitude less customers to stay afloat. If you can't sell for that price, rethink your product or ditch the bootstrap idea.
