Our Investment in Enzymatic DNA Synthesis Technology Capable of Powering New Products in Industrial Synthetic Biology, Personalized Therapeutics, Precision Diagnostics, and Eventually Information Storage, Nanotechnology and More
By Brent MacDonald – Principal @ Rising Tide VC
Molecular Assemblies began more than 30 years ago when Bill Efcavitch and Curt Becker, then early founders at the pioneering biotech company Applied Biosystems, commercialized the first practical method of synthesizing DNA. Known as phosphoramidite synthesis, this chemical-based method was a significant breakthrough and remains the industry standard for making DNA today. It led to a wide range of tools and technologies using DNA and helped spawn the biotech industry as we know it. In 2013 Bill and Curt founded Molecular Assemblies to create a new approach to DNA synthesis. Their aim is the holy grail of DNA: enzymatic synthesis.
Molecular Assemblies is developing an enzymatic, platform-independent synthesis technology that produces long, high-quality, sequence specific DNA reliably and affordably. In just three steps, its enzymatic process is simple, seamless and sustainable. Unconstrained by scale, format or platform, Molecular Assemblies’ enzymatic synthesis process is broadly applicable across new and emerging industries. The highly experienced executive and scientific team believe that DNA will become the industrial polymer of the 21st century and they are enabling that future. In fact, a recent McKinsey & Company report suggests that as much as 60 percent of the physical inputs to the global economy could be produced biologically. Most anything made with petrochemistry—your carpets, cosmetics, and contact lenses, to name a few—could soon be made with biology. Not necessarily because it’s greener, but because you can engineer biology to make things more economically and more precisely.
One of the more fascinating and less intuitive applications of DNA synthesis is data storage. DNA is the most compact and durable information storage molecule that exists in our world and there are good reasons to believe that the future will be written in DNA. The world is producing more digital information than can be efficiently stored. An estimated 1.7 megabytes of data will be created per second per person globally, which translates to about 418 zettabytes in a single year (418 billion one-terabyte hard drive’s worth of information), assuming a world population of 7.8 billion. DNA represents an essentially limitless hard drive in nearly zero space. DNA data storage is thought about as the “golden backup.” It might take a day or two to retrieve a complete restore, but it will always and forever be a lossless, failsafe backup, capable of recording anything and everything users could ever want. It is also expected the cost of storing information in DNA could drop to $100 per terabyte in as little as five years.
In summary, DNA synthesis is a growing and potentially booming space, much like DNA sequencing in the early 2000s. We believe Molecular Assemblies’ approach in developing an enzymatic method, alongside its skilled team, makes it a compelling investment. Its potential to integrate into other DNA synthesis hardware platforms can also provide additional avenues for value creation.
