Most crowdfunding is aimed at consumer/hobbyist, and doesn't really target the industrial/commercial sector. There are some exceptions, such as retailer pledge levels for things like new board games. There are also some specialist crowdfunders for the commercial sector, e.g. CrowdCube in the UK (not sure where you are).
What I've seen my clients do is to partner with a large customer in the target sector who can see the value in the technology for their own use, and doesn't mind helping it to market. They benefit from getting a headstart with the new tech, and also financially as a longer term partner, which you get some upfront funding to manufacture & trial your product. This can obviously be a problem in some sectors where there are few players, or that are very competitive.
Another option is to partner with a industry group (like the local Torsional Coupler Society... LOL), who like the above example want to help get their members benefit from new tech. Or maybe work with a university or research group who has industry contacts. e.g. In Australia we have the CSIRO (
