Logo for a Web 2.0 regression testing platform

regressr

We are a Web 2.0 startup that allows developers and quality assurance staff test their web application across a variety of web browsers. Our goal is to dramatically lower the cost and difficulty of web test automation.

We want to convey that we are:
- professional
- established
- modern

- Web site developers
- Quality assurance staff
- Project managers

Overall our audience will be web savvy and somewhat technical. Age range 25-45. Primarily male.

Ideas:
- Primary design element should be the name: regressr
- No ".com" in the logo please
- Simple vector illustration in the logo might be nice (stackoverflow does this very well)
- We have no existing color palette, so feel free to experiment
- Logo should be suitable for a web site and for business cards
- Simple and bold is preferred.
