Martin Chard, a dyslexic and autistic construction worker always had a problem accurately marking the holes for installing fixtures. He invented the pressurized MarXman chalk pen to make his life simpler and his work more precise. He partnered with his wife, Jenny David, to start the MarXman business. What Happened During The Pitch? The MarXman makes alignment easier and a much simpler task. It also makes drilling holes more accurate and saves construction workers or DIYers a lot of time. Who Is The Owner? The chalk never dries out or clogs up like an ink marker and does not dull and need to be sharpened like a pencil. Touka then offered half the money for 15% with another Dragon to benefit the business. Sarah Willingham offered to partner with Touka for 15% and half the money.
