Can YComb / TechStars help build a large sales / tech co? (Groupon / ZocDoc)

It seems like Y-Combinator, TechStars and the like are focused on building innovative technology that scales with few people. But some of the fastest growing companies lately are essentially new-age marketing / lead-gen businesses built on successful sales teams with minimum technology behind them (in the beginning at least).<p>Any thoughts on how these types of companies have fared in accelerators if some have started there?
