Per the product's official site, the HavenLock is now the Haven Lockdown, but the company appears to be offering the same type of services.
Interestingly, Alex Bertelli and Clay Banks reportedly saw a new opportunity for their business come about in the space between their "Shark Tank" episode being filmed and when it actually aired. According to WKRN, they partnered with pest control company Terminix to sell the product directly to consumers. Additionally, the product is not only still available to purchase on their website, but the company also continues to do deals with schools across the country to help with classroom lockdowns. In 2023, they even received a SAFETY (Support Anti-Terrorism by Fostering Effective Technologies) Act Designation from the Department of Homeland Security, according to AP.
The HavenLock pitch also experienced an afterlife in the "Shark Tank" universe. Thanks to the infamous door-kicking mishap, the product (or, more accurately, the pitch for the product) made it onto the "Greatest of All Time Special" that aired in February of 2020. As you can see in the clip, the Sharks seemed to love the pitch even if they didn't end up buying into the business.
Now, the Haven Lockdown is a successful home security product even without any investment from the Sharks, although its extremely memorable and funny pitch on the show certainly didn't hurt it. It just goes to show that even ostensible failures can ultimately produce success, which has to be one of the core concepts behind "Shark Tank."
