I was a TechStars Seattle finalist this year. We applied with a product/idea that was also implemented by another company in the most recent YC batch (I also applied to that batch before TS but didn't get an interview).<p>To answer your last question, yes, I think it's somewhat of an indicator that you have potential. It means, at the very least, you piqued the interest of smart investors. Not getting in just means a few dozen people had better ideas, better teams and/or more traction in their minds.<p>Of course, being a finalist doesn't beat having a product out in the market that people are buying/using.<p>For me, it was a good experience doing the interview with TS staff/investors, understanding what they want, etc. I've had moderate success with bootstrapped startups–but the accelerator/angel/VC world is new to me. Knowing you were in the top 25 applications out of 600 is an ego boost for about ... a week.<p>Here's the deal, though ... I've shuttered that idea. Partly because I know other people now have a leg-up, partly because I'm not in a big metro where it's easier to get traction, but mostly because I'd rather do something I'm a little more passionate about (Cilantro) and experienced in. I've applied to YC again–if I don't get in, I'll still plow forward. I've already got an MVP and users. I doubt I'll apply to TS again (moving to the valley is easy for me. Seattle/Boulder, not so much).<p>I don't know if that answers any of your questions, but that's what I got.
