Dear Potential Sponsor,
Please sponsor PyMOL by purchasing a subscription covering your scope of usage. The impact of your sponsorship will be permanent, cumulative, and directly observable to you through PyMOL's ever-increasing capabilities. Every useful new feature we can release under an open-source license permanently expands the foundation of software which will support future scientific, medical, and educational advances.
All good software requires equipment, time, resources, and hard work to create. To offset such costs, you can either:
pay large and obligatory license fees for Proprietary Solutions
optimized for maximum vendor profits,
...or...
Consider:
Which approach gives you more freedom and flexibility in your research?
Which approach best enables cumulative progress in scientific software tools?
Which approach saves you the most time and money over the long run?
Corporate users, reflect for a moment on the very high price of comparable commercial software, and then consider the question, "Can our company afford not to fund PyMOL?" There are many reasons why it makes sense do to so.
This project cannot succeed without your help, so not funding our effort means your are assuming unnecessary future costs in meeting essential software needs. PyMOL is a promising open-source alternative, so why not help it to succeed? Over time, it will save you money and provide for increased choice!
| Cheers, | |
