On the Treasure Coast, we’re bringing innovation to life.

Founded in early 2019, Exothermic Technologies, LLC has taken the market by storm with cutting-edge product design and patent-pending technology.

Owned and operated by firearms and firefighting professionals, our combined experience, networking, and proven success across multiple industries has allowed us to forge a team like none other. We’re setting the standard and continuing to raise the bar.

We promise to always put you first.


We respond quickly to all communication. With Exothermic, you’re a priority. We treat you with the respect you deserve. (Sometimes you might get caught in email filters, so if you don’t hear back from us within 2 business days, give us a call!)

We stand behind our products. While we have numerous inspections and tests throughout our assembly processes, no component is 100% invulnerable to issues. If you ever experience a problem, we’ll do everything we can to ensure it’s resolved and back out to you within 24 hours of receipt. We always take care of our customers.

Thank you very much for going above and beyond even when it is not your fault. This just goes to show the type of company you guys are and the level of customer service you provide as well as how much you care about your customers safety.Davis T.

This is literally incredible. I have never before in my life written a company (overnight no less), and had 2 responses and a tracking number within 6 hours. Not even close. I’m gonna 5 star review the shit outta you guys. Absolutely amazing.Robert B.

I work in customer service and I know the importance quality service has for small businesses. Because of your professionalism and courtesy, Exothermic Technologies will have my flamethrower business until I die. Granted, I don’t expect to need many flamethrowers in life, but whatever.Sam S.
