The best way IMHO is have a good/interesting problem for them to solve. Something they could potentially care about from a developer/tech perspective. I "earned" my technical co-founder exactly by finding a smaller problem to solve from the really big one I had in mind. Paid him to do it and made him realize that this was an interesting problem to solve while still a good business to be in. The smaller problem he helped me solve has turned out to a pretty good business so I can't wait for what the bigger problem will do for it. Now we are building some really great stuff.
