The first couple of hires should be someone with good knowledge (and contacts preferably) in the chosen market for business development / customer success, and then someone with good all-around tech skills as a first engineering hire (assuming you have a technical co-founder as CTO who took the product to MVP level). After that it's entirely driven by who the product is for - if it's a straightforward tech product for B2Bs you're going to need more product and sales than tech, but if it's a consumer app that needs to scale fast then you'll have to push in to tech hires rather than sales.
