This week in L.A. tech: Three Day Rule lands funding, Snapchat snags encryption expert and Surf Air flies north

Three Day Rule, a matchmaking service with headquarters in Santa Monica, has raised 650,000 from the Dallas Angels Network investment group and 550,000 from several wealthy individuals. The company's 20 matchmakers -- spread across seven cities -- use software and intuition to find potential partners for customers, who pay about 4,000 for three months of assistance. Three Day Rule identifies matches from its own database, which includes people who have signed up free of charge at networking events, industry conferences and on the firm's website. But the pool goes beyond that. JDate, Christian Mingle and OkCupid allow Three Day Rule to choose from people listed on those dating websites too.
