FlexScreen: What Happened After Shark Tank

FlexScreen: What Happened After Shark Tank

In case you missed it, the popular show Shark Tank aired an episode featuring a new invention by FlexScreen entrepreneur and CEO, Joe Altieri. The product is a replacement window screen that can be sized to fit any window size and features a magnetic strip for easy installation.

After Altieri made his pitch, he received offers from two of the Sharks: Mark Cuban and Lori Greiner. They were both impressed with FlexScreen’s potential and wanted to invest in it in exchange for a 30% stake in the company. After some negotiation, Altieri accepted their offer and sealed the deal on air. But how has FlexScreen fared since the show aired? Let’s find out!

Story Behind the FlexScreen

FlexScreen is an innovative replaceable window screen system co-invented by Joe Altieri. Joe had experience in the replacement window industry and noticed that existing screens were kept in place by staples, tape, or a combination of both. Screens also are prone to getting dirty and sagging over time. He wanted to create something better. 

And so, Joe invented a FlexScreen. FlexScreen is a replacement window screen that is held in place by tension and can be removed easily without the need for any tools. The screen provides a cleaner, more durable option than traditional window screens.

The screen is a PVC-coated steel spring frame. This is the secret behind FlexScreen’s patented design. The frame is flexible and can be used to fit almost any window size or shape. And best of all, it’s also easy to clean!

Each display is tailored to fit your specific needs. All you need to do is measure the height and width of your window, select the size on their website, and order online. FlexScreen can be ordered in any color you choose from black to white to even just clear.

As for the price, Joe sells his screens for $ 70 per window, plus the cost of shipping. To reach a wider audience, Joe wants to receive help from a Shark. [1] [2]

How Did the FlexScreen Shark Tank Pitch Go

Joe is looking for an investment of $ 800,000 in exchange for 6% equity in his business. He begins with an explanation of the FlexScreen product and how it compares to traditional window screens.

He’s been working on his venture for five whole years and during this time he managed to sell over $ 5 million of his product. Joe then demonstrates how easy the installation is and promotes the various features of FlexScreen.

The Sharks seem impressed with Joe’s determination and inventiveness but they also express some doubts about him selling his product to manufacturers directly instead of through a middleman. Mark Cuban suggests that Joe focuses on selling his product to Home Depot or Lowe’s, in order to reach a larger market.

Nevertheless, nearly everyone is interested. Kevin goes first, offering $ 800,000 in exchange for $ 800,000 for 20% contingent on a licensing deal with a major window manufacturer. Then goes Lori who offers $ 400k in cash and a $ 400k line of credit in exchange for 10%. Barbara is interested as well and offers $ 400,000 in cash and a $ 400,000 line of credit in exchange for 50% of the retail business. Initially, Joe seemed to go with Barbara’s offer, but then considers Lori’s relations to the hardware industry and roles back to her offer.

Joe, who seems to be struggling with the decision, ends up accepting Lori’s offer. His venture has been funded and he is now ready to bring his innovative product to the mass market. Thanks to FlexScreen and Shark Tank, Joe Altieri can now become a big name in the replacement window industry! [2]

Luckily, Joe had managed to close his deal with Lori Greiner and the two are working very closely together.

Furthermore, it’s reported that he has plans for more facilities in the near future. Joe had planned on introducing his product to retail, and he succeeded at that!

This was achieved thanks to the partnership with Saint Gobain, one of the largest window manufacturers in the world. They now offer FlexScreen to their customers and most of the major hardware stores across the US. Joe’s product is also available online with Home Depot and Amazon featuring it!

Of course, such commercial success means they require more working power, and so Joe Altieri has been able to employ over 150 people in the last two years. This is remarkable for a Shark Tank business and it shows that not only was FlexScreen worth investing in, but it has also brought jobs to many people!

The company also made it to the annual Inc. 5000 list of the fastest-growing companies in the US.  This achievement is a testament to the hard work Joe Altieri and his team have put into making FlexScreen as successful as it is today. 

FlexScreen also managed to secure a partnership with Harvey Windows, one of the biggest window manufacturers in the United States. This means that now customers who buy windows from Harvey Windows can choose to buy FlexScreen as well!

They keep opening new factories and have plans for many more. As far as the sales go, in the year 2021, they hit $ 20 million in annual sales, which is an amazing achievement for a Shark Tank business.

The social media presence of the company is also decent. Their Instagram account boasts 4k followers and their Facebook page has 17k likes.
