I agree that some certifications are out of style, specifically in programming because you can glean so much more data about a candidate from their code rather than a certification.
However, in other areas, if the certification is sufficiently difficult to attain such as Cisco's networking certificates, or where you can't assign a task or review past work to determine an individual's skill level I think certifications can be helpful even in a startup hiring environment.
For example, if you are applying as a product management and have relatively junior experience but you have a great feel for our product and market I would still be potentially worried about how well you can interface with a team. So seeing a certification around SCRUM or Agile, in this particular case will certainly be helpful.
