I have a software project that I'd like to release as open source. Its a quite complex tool that >50% of the industry i am in will use (i worked in it for a number of years, hobbyist and students would use this as well). I think i can get my company or another to develop it but then it would be closed off only available from licensing (which will require phone support and other issues if gone that direction) and i rather have it open source with a community behind it.
After brainstorming i thought i could get sponsors to continue the project and heavily advertise them. I'm not sure how to go about this. (the asking them to be a sponsor)
I was thinking maybe i should ask for only enough to get to the first stable release (30K, 6months and a 2nd tool for another 20k and 4months) then build a community and perhaps ask for additional funding. But i am not sure if that's the best way to go about this.
How do i ask a company to be a sponsor? and what promises might they want me to make or what promises should i make from the beginning
