The company behind Rhino, Robert McNeel & Associates, has also managed to stay small (

> In the last few months, there has been a lot of talk in the CAD community about proprietary file formats and how companies protect them. I would like to know how a CAD system like Rhino was able to succeed with a file format that is open, documented, and free (OpenNURBS).
The CAD users need and want open high-fidelity data exchange.
Unfortunately, open file formats are not in the best interest of investors. Investors would rather bet on companies that have a protected proprietary market.
Unlike most CAD companies, we are not a public company nor are we venture capital funded with plans to be public. That means that our only customer (and source of income) is our users.
> Rhino users had to wait a few years between Rhino 3.0 and the new Rhino 4.0. In the mean time, they enjoyed a continuous stream of improvements and bug fixes delivered to their PCs by the Rhino automatic updating system. Based on how well this system has worked, are you considering moving from a release-based system to some sort of subscription-based system?
No. Again, those systems are usually in the best interest of the investors. Our users have the luxury of not having to buy upgrades until we provide something that is actually useful to them. In addition, all current users get to be involved in the development process are every stage, not just for a couple of months at the end. Since we don’t pay any attention to what other CAD companies are doing, we rely on the users to provide the direction for each new release.
