It would be awesome if you could get your GMAT up to 700. The good news is that you've got US experience & it sounds like you've made real impact in the companies where you've worked. The bad news is that, as you probably know, you're coming from the toughest demographic out there when it comes to b-school apps & it's one that tends to have very high GMAT scores. That means that you ideally want to try to exceed school's average scores (since typically the average score for your demographic is higher than a school's overall average). That said, even if you are unable to bring your score up, I think you're still on track with your schools. Haas & UCLA will be a bit more of a reach if you are below 700 but not completely out of reach.
A lot will depend on your post-MBA goals as well. Product manager is the most common goal for your demographic (followed by consulting), which is not to say it's a "bad" goal but it will be critical to make your story as strong & as unique as possible. That means being specific about what type of product you'd want to work on & why in the short term. For the long-term, if you do plan to start a company, you'll need to be ready to explain what your company will do. What unmet need will you fill or what problem will you solve? Why is this your passion? (they want to not only see the business case that demonstrates demand for your idea but also the reasons why THIS is what you want to devote your life and career too. You can make a business case for all sorts of things, so why is THIS where you want to focus?) And you'll also need to be ready to explain how you'll compete with potentially large, well-funded/resourced competitors who may also be going after this same idea. It would be worth considering possibly taking a different track with your LT goal & targeting VP of Product Management in a larger firm for example. Entrepreneurship is a tough post-MBA goal for the reasons I mentioned here. If you are a VP at an established firm, however, you can still pursue an innovative idea, only you'll be armed with the resources that a start up doesn't necessarily always have. Either way, your whole argument for why you need the MBA ultimately rests on your career goals, so it will be really important to make sure those are as strong & as specific as possible.
