Long Wharf Shark Tank Update

Plastic is a huge problem; people worldwide are tossing it into the ocean. Long Wharf Supply Co. is on a mission to tackle this plastic issue. Their whole deal is all about reducing the impact of plastic and oyster shell waste on the environment. They’re making money while doing it.

They devised this genius idea to use those waste materials to create awesome products. The founder launched a campaign on Kickstarter back in July 2020. Their goal was to raise $20,000, but guess what? They blew past that target! By August 19, 2020, they had raised $75,009 from 482 backers. The founder seeks more investment to take the company to the next level. That’s why they planned to hit up Shark Tank.

Founder and Backstory

The founder and CEO of Long Wharf Supply Co is Mike Lamagna, and his childhood was all about those sandy beaches and boats in New Hampshire. After college, Mike headed to the big city and studied finance at Merrimack College in New York City. But get this: he didn’t stop there! In October 2014, he joined Harlem Lacrosse as an advisory board member and is still rocking it there.

Mike and his sister, Lauren, started Long Wharf Supply Co in 2016. They had this genius idea to use oyster shells and plastic bottles to make top-quality yarn, which they then turned into these amazing sweaters. They wanted to create stylish sweaters and contribute to cleaning up the environment.

It’s amazing how their family background in the sweater industry inspired them to make a positive impact by using waste materials. They’ve successfully created their unique clothing brand with a strong focus on sustainability. Now, Mike is running this business part-time while also working at another company. It’s impressive how Mike is handling everything.

Pitch and Deal

Lauren and Mike went on Shark Tank with their company, Long Wharf Supply Co., and asked for $375K for 15% of the business. They showed off their awesome sweaters made from reusable plastic material. The sharks were impressed with the softness and weight of the sweaters. The entrepreneurs explained that they use 10% lambswool and 50% of their recycled material in the sweaters.

The remaining 40% comprises 20% nylon and 20% plant-based viscose. Each shirt has a gross margin of 80%, costs between $23.50 and $33.50 to make, and sells for $128 to $158. They’ve had sales of $495,000 in the past year, but their customer acquisition cost is a bit high at $41.

Kevin O’Leary and Daymond John decided not to invest due to valuation concerns and personal reasons. Mark Cuban suggested selling t-shirts with the material, but Mike believed they could sell 5 million sweaters instead. Lori Greiner opted out, but Peter Jones told giving shares to Lauren, who wanted a 10% stake, and Mike agreed.

Then Peter Jones offered $375,000 for a 45% equity. The entrepreneur countered and contributed 25%, but Peter said no. So, this deal did not happen in Shark Tank, and that’s how the company left the show without getting a deal.
