Is this actually just only for startups, or is anyone eligible who might get under 500 mentions a month? I work for a mid-sized company that isn't really startuppy anymore, but I think the marketing folks would love to try this out. I don't think we get >500 mentions a month, but if we did, I could definitely see them making the investment.
It's just how they named the plan: "The Startup plan is perfect for businesses, side projects or individuals who get less than 500 brand mentions on Twitter each month."
