Tools I learned about from 30 hardware founders

I had dinner with 30 hardware founders and discovered a ton of relevant tools. Figured I'd share them here. I myself am trying to build something in the space so it was helpful, but I'm curious what sort of tools the hackernews community might recommend?

1. bomhacker.com - basically saves you money on hardware.

2. Crewfire.com - get your group of die-hard supporters to support you on a recurring basis. Reward their facebook/twitter shares. I prefer crewfire to thunderclap.it

3. plethora.com -- this is super dope for anyone who has dealt with mfg issues.

4. grabcad.com - useful community resource for tons of MechE's.

5. LACI - LA incubator with $20M worth of hardware.

6. import.io - you can scrape indiegogo, kickstarter, and crowdtilt and see analytics on past crowdfunding campaigns.

7. leadfeeder.com - if you're selling an expensive product, this is a fast way to know who is visiting your site so you can approach them to talk about your product. "

8. Prefundia.com - launch your campaign in beta to test the waters.

Curious if you(all) know of any others?
