Presentation from my talk at APIDays+APIStrat in Berlin. The API economy has emerged as an increasingly robust and important area of the tech landscape as APIs have proliferated. APIs become fundamental building blocks in today’s software development process. They enable one company to solve a difficult software development challenge (e.g. cloud storage, in-app email, payments processing) and let other companies access that solution, rather than re-solve the same challenge during their own development process . Today the best way to do business isn’t to build it all in-house. Top companies are increasingly piecing together a composite of APIs from specialized startups. That lets them concentrate on their unique value-add rather than reinventing the wheel.
