If I've learned anything from launching a product thats getting some real traction, there is no _Later_, and _Next_ keeps slipping further into the future. It's okay to move a little bit slower and make sure you get decisions right since you'll likely never come back to what you're working on now, and if you do it'll be years later. This doesn't mean that you should sit there and built everything out today as if you're Googlescale, but don't be afraid to move a little bit slower and consider some more options including rolling your own if it makes sense.
