Sampa, a Seattle startup that made it easy for families to set up a central place to share photos, blog posts and other information online, is shutting down. In a message on its site posted Friday, Sampa says it wasn’t able to pay its bills to keep the service up: “We feel bad for all the people we disappointed, from our avid customers to our investors, including our families that have actively used the service themselves and supported us during this journey.” Sampa had raised $1 million in an angel round a year ago.
