Working at Weebly, you have similar hours to BigCo (although you'll be 10x more productive), paid market rate (or slightly above), and receive your fair share of the outcome.
You also get to work with a fun group of people who are obsessed with being productive, and not much else. Maybe we're the exception, but we don't care if you're a 9-5 type of person, if you're very productive during those hours.
Working at a startup doesn't have to be shit, just because some startups are.
I'm not a startup cheerleader -- "come change the world!" is the most overused pitch line ever -- but there are tons of examples (37signals, some YC teams, some of the larger NY startups) countering this generalization.
It's clearly not all unicorns and cupcakes, but there's a difference between "work for us at 2/3rds market plus 1%" and "we're VC-backed, work for us at market and get health plus other nice perks." Startups are not uniform.
