Pink Slip Day

Layoffs are coming fast and furious, with at least four major employers announcing cuts today. AOL (a unit of Time Warner), Boeing, SAP and Starbucks said they collectively plan reductions totaling 22,000 positions. The moves follow a NYT story on Monday that said Caterpillar, Home Depot, Nextel, Sprint and eight other companies that they would chop more than 75,000 jobs.

I’m compiling a list of venture-backed companies that have done layoffs since October. Scanning various news outlets, I’ve turned up 18: AdBrite, BioControl, BitTorrent, Egenera, Federated Media, FiveRuns, Helium, Imeem, Jive Software, LinkedIn, Mahalo, Motion Computing, SearchMe, Sezmi, Six Apart, Spot Runner, Technorati and Thumbplay.

The layoffs were reported by various media outlets, including the Boston Globe, paidcontent.org, the New York Times, Silicon Alley Insider, TechCrunch, VentureBeat and VentureWire.

Who’s missing from this list?
