Business: Social games for gamers (http://www.ea2d.com)

Languages: Java backend, AS3 frontend, Python + Ruby misc

Note that we're very new (and hiring!), so much of this is still being built out.

Software lifecycle: git for SCM (GitHub as central repo); ant for builds; ivy for dependency management; Bamboo for build automation; Crucible for code review; JIRA for issue tracking; Greenhopper for sprint planning; Vagrant for containerized development environments

Systems infrastructure: AWS (EC2 w/ELB+ASG and S3 for now, more services to come); nginx-fronted Tomcat for JVM; Cassandra for persistent DB; chef for configuration management (currently chef-solo, but evaluating Opscode Platform); PoolParty+Fabric for one-click deploy server fleets; Nagios + Pingdom for monitoring; Mixpanel + Kontagent for analytics; Dynect (likely) for DNS, possibly for GSLB; Akamai (likely) for CDN, possibly for GSLB

Misc: PagerDuty for on-call stuff; Google Apps for email, shared docs, etc; Confluence for wiki; OpenFire (Jabber) for chat

Sounds neat, but is a subsidiary of EA really considered a "start up"?

I definitely wouldn't consider EA2D a startup, but fortunately the OP left it open ("startup/company").

That being said, I do think we (EA2D) have a lot in common with later-stage startups. Three big factors are our autonomy (near-complete), self-sufficiency (product, dev, marketing, ops, etc. is internal to our studio) and size (just 27 people across all disciplines). I bet our stack more closely resembles that of a startup than that of an enterprise.
