Pluspunten
This company is home to the best and the brightest people I've ever had the pleasure of working with. The current employees are the cream of the crop--most come from very large software companies and were key contributors on multi-million dollar software offerings in their past lives.
The executive team is very accessible with the CTO/partner in-house and heavily involved in day-to-day activities and very frequent and personal visits from the CEO, COO, and Sales exec. The company is also small which gives employees the opportunity to contribute in several areas (development, architecture, and even sales) and face-to-face client meetings are not reserved for only the most senior members of the team, allowing junior engineers to grow quickly.
Although the environment is very results-driven, it's also very family oriented and fun. The Raleigh site has a built-in bar/cafe area that hosts weekly company-sponsored Beer Fridays and other off-site events focused on bringing the entire team together. I've worked here for a year and a half and it's been the best stretch of my career thus far; I'd recommend PointSource to anyone who is driven to achieve and wants to see his or her results make a difference for the company.
Minpunten
The only con that I can think of is that it may not be for everyone. The group here is very success-driven, motivated, and hard-working with a thirst for knowledge and innovation. There is excellent training and mentoring, but everyone is expected to work hard and put in the time necessary to get up to speed as quickly as possible and become key contributors. The project teams are pretty small, so there's no way to "coast" and not be noticed.
