An updated take on the old, boring doorbell.

Read more about this product straight from the founders below!


DoorJamz brings web technology and high design to an old and stale product category, the home doorbell. DoorJamz allows a homeowner to wirelessly customize their house’s ‘ringtone’ to anything they choose or program different ringtones for different days of the week, time of day, holidays, or even by their moods. Boring doorbells no more! This team wants to be at the forefront of smart home products and hopes to get there with Daily Grommet’s help.


Team Bio: 

It all started in 2005 with a couple of friends, who have known each other since Mrs. Beattie's 4th grade class, getting together late on a Thursday night after the kids and wives were asleep to rebuild a 1941 Chevy truck. Although there were definitely good times, "Truck Night" inevitably became a time for innovation, product development and start-ups...a time for skunk works types of projects.

At our core is a passion for creativity and design, to innovate, build stellar brands and enjoy life. KMN's initial product debut of the DrawerDecor system was a significant achievement in our efforts to succeed in the world of consumer product design and manufacturing. Its high design and unique innovation have helped establish KMN as an up and coming consumer brand with endless potential.

The founders of KMN are a solid team and trusted partnership with equal ambition.  Both have a strong technical and engineering background yet have been successful performing all areas of a start-up company.  Their collaborative achievements have also included the design, commercialization and license of The Caution Clip® to a third party for mass market retail as well as the marketing and brand creation for a start-up homebuilding company.  Pathway Homes was founded in 2006 and has grown into a multi-million dollar company.

Keith M. Nielson, CEO & co-Founder – As the namesake of KMN, Keith is an inventor and artist with a passion for creating new products and building a team into a great company.  He holds a B.S. in Mechanical Engineering from GMI (now Kettering University), Michigan Real Estate Salesperson's License, Private Pilot's License, Instrument and Rotorcraft ratings, Ice Rescue certification and is a blue belt in Brazilian Jiu Jitsu. He has over ten years of c-level management experience in manufacturing, private equity, real estate, home building, and oil and gas. Keith is also a member of the Young Presidents Organization (YPO). Keith lives in Traverse City, Michigan with his wife and four kids.

Kevin M. Vann, President & co-Founder – Kevin has been responsible for the overall operations of KMN since its founding.  He is a passionate entrepreneur and problem solver with a creative mind and detailed eye. Along with his project oversight experience, Kevin’s academic background in engineering demonstrates his strong quantitative and analytical skills. He holds a B.S.E. in Naval Architecture & Marine Engineering and M.S.E. in Industrial & Operations Engineering from the University of Michigan. Prior to co-founding KMN, Kevin worked as a Naval Architect and Marine Engineer in Bristol, Rhode Island as well as Vice President of Real Estate Development & Trust for a family office in Traverse City, Michigan. Kevin enjoys spending time with his wife and two kids at their home in Suttons Bay, Michigan and are close to completing the adoption process for their third.
