You might need to do both, and it depends on your ideal customer's buying patterns. If that buyer typically purchases your product and your competitor's product in a single transaction, and that buying pattern makes sense, you gotta to build, buy, or partner to offer your competitor's product. If you don't, you could quickly get shut out of the market altogether. Partnerships are messy, but they're so fun. It's good to have friends in the market, and making the choice to partner can really clarify your company's purpose: the problem you want to be known for solving better than anyone. Last thought: when you do pick a truly new problem to invest in solving, just make sure it's one you and your team care deeply about. You only got so much time to play with--do you really want to use it building a better mousetrap?

It's easy to get hung up on the word "strategy." There's no magic in it: a GTM strategy is just a documented set of decisions and a plan. It's words on paper, and the purpose of it is nothing more than alignment. To hit your sales, revenue, and margin targets, you've gotta get and keep everyone on your team aligned on what needs to be done, why, by whom, and when. A good GTM strategy document answers all the questions mentioned in other answers. Questions about buyers & pain points, budgets, product overview, competition, differentiation, pricing, partners, sales & marketing plans, success criteria, etc. A great GTM strategy, however, will inspire your whole team to row hard in the same direction and make some magic together. The way you engage your team (or don't) in the process of creating your GTM strategy, and the way you communicate it, makes all the difference.
