What you are describing is enterprise sales. I co-founded one of those. Early traction is easy to spot: - at first, you can barely get first meetings with any potential customers. You track how many companies even agreed to meet with you once. - a few months in, you get your hopes up (incorrectly - usually). A few companies you met are talking about doing an evaluation of your product. - another few months go by, just one of all your contacts moved to do an evaluation, but then they postponed their purchasing decision to the next fiscal year. - still no revenue, but now you have a funnel: x prospects in first meeting, y prospects in second meeting, z prospects in eval, 0 prospects have bought. Keep tracking those numbers and the trend will be clear.
