I am looking for a broad appeal to both tech-savvy users and non-tech-savvy users. The potential customers are attorneys both at law firms and also at corporations (in-house counsel), and in the future, even normal citizens/law clients will be customers. Therefore, the logo should appeal to all types of clients (but mostly attorneys for now).
The main target audience is the most tech-savvy users who appreciate technology and see how it can benefit their business. However, lawyers by default are often very conservative and resistant to new technology (and not very tech savvy). The logo should be warm and welcoming and accepting of even non-tech-savvy users. It should be a familiar, simple type of logo that lawyers would recognize from the technologies they are already aware of (Google, Facebook, Skype, etc.).
The demographic is probably a slightly older demographic, probably mostly male as well. However, as noted above, the appeal should be broad, as the initial target customers will be younger and more tech savvy.
The logo should somehow straddle the divide between the old-fashioned, conservative elegance of the legal field (old wood-grain offices with green leather couches) to the modern, sleek, high-tech legal field of the future.
