I'd agree with Jason. Early, aka pre-revenue, it is more a function of the venture math. Generally, it about how much capital does a startup need to prove a thesis. Over time this feels like $500k-$1MM at the seed stage. Using basic venture math from an institutional investor of 25% ownership in the company. That puts the company at $2-4MM pre-money valuation.
It changes post revenue, not post consulting revenue, it needs to be revenue that demonstrates a valid hypothesis about the Customer Acquisition Costs (CAC) or the Customer Lifetime Value (CLTV). Targeting $50k/month and the valuations starts to go up. But this looks like an Series round with a much higher valuation $8-12MM pre-money (maybe higher - depending on team, market and other factors).
The "enterprise" thing is less important. What I want to know is how well you know your potential customers, how full is the top of your funnel, what are the decisions that a buyer makes at each stage of the funnel, and how many prospects are at the different phases.
