Hot News for the Summer from CATALOG

CATALOG Encodes Wikipedia Into DNA!

After years of development work and immeasurable effort by the CATALOG team, we have performed the first substantial run of our DNA data writer! We encoded the English text version of Wikipedia into synthetic DNA molecules using printer technology, our groundbreaking encoding scheme and chemical protocols. The total amount of data came to 16 gigabytes, significantly more digital information than has ever been captured into DNA previously – not to mention orders of magnitude faster and cheaper than chemical synthesis approaches.

This fantastic piece, created by filmmaker Jacob Hurwitz-Goodman (the talent behind our first video) shows how the system functions, and the efforts that went into this moment. Once it’s up to full speed, the system will be capable of encoding a terabit of data per day, or about 125 gigabytes.

We promise the ten-minute video will captivate you, and look forward to putting the system to work encoding pilot customer data, once it’s arrived at our new Boston office! We are already lining up pilot agreements with large companies and organizations across industry and governmental sectors. These groups will work with us over time as we develop both our DNA data storage and computational technologies. Would your organization like to be part of these efforts? If so, please reach out to CATALOG’s Nick Gold.

Our Team Continues to Expand


It’s always exciting when the team grows, and CATALOG has two new members who have joined us since our winter update.

First is Sean Mihm, who joined us in February as our Mechanical Engineer with an expertise in microfluidics and device automation. Sean is a Georgia Tech graduate with a major in Chemical & Biomolecular Engineering, who then spent a couple of years in the private sector with a medical device startup. Sean self-identifies as a “maker,” and is able to leverage his passion for engineering and building things as he helps us scale our Terabit-per-day DNA writer up to Petabit scale. When not behind a screen, he enjoys hiking, stepping into the boxing ring at a local gym, tweaking his 3D printer and rebuilding his road bike. He’s looking forward to taking his love of rowing into the Charles, once he can find the time!

Next is Nick Gold, who in April took the role of CATALOG’s VP of Marketing. Nick spent 15 years in business development, solutions architecture, marketing and consulting for a national media technology systems integrator. His previous firm designs, deploys and supports data storage, information management, and workflow automation systems for rich media users. These include some of the top studios and broadcasters, pop stars, as well as government agencies, NGOs, and Fortune 500 firms. Nick is thoroughly excited to be working with CATALOG, as he has been reading about advanced technologies for decades in his favorite works of cyberpunk science fiction. When not geeking-out as an armchair futurologist, Nick enjoys spending time outdoors hiking and camping (admittedly with Kindle in tow).

In mid-April we moved from the Pagliuca Harvard Life Lab to a new office we are calling home at 56 Roland Street in Boston’s historic Charlestown neighborhood. Not only does this afford us our own dedicated lab space and more room to grow our team, but also an annex that will house our DNA writer once it’s been shipped from its current location in the UK.

CATALOG is now officially engaged in our Series A fundraising activities! Our CEO and Co-founder Hyunjun Park was in San Francisco and Silicon Valley meeting with investors for two weeks in the second half of June, and he’ll be back out for additional meetings the week of July 8th.

Hyunjun’s globetrotting has also included speaking at a number of conferences including EmTech ASIA, and a series of events held by MIT’s Industrial Liaison Program in South Korea, Japan and Austria. He also presented at the Digital Asset Symposium, put on by The Association of Moving Image Archivists at the Museum of Modern Art in New York City. Finally, Hyunjun spoke at the MIT Startup Ecosystem Conference, CATALOG being one of the STEX25 group of startups.

Looking ahead, our VP of Marketing Nick Gold will be moderating a panel on the future of archival technologies at the Sports Video Group’s Sports Content Management Forum on July 24th in New York City. Hyunjun will be speaking in September at the Library of Congress’ Digital Preservation Meeting. On October 7th he’ll present at Long Now Boston, followed by the Fujifilm 11th Annual Global IT Executive Summit which runs October 23rd-26th, and then at Chicago’s Dare Mighty Things conference on October 28th. If you can, plan to join us at one of these events!

CATALOG in the Press

We were thrilled to have CNET cover the inaugural run of our DNA data writer and encoding of Wikipedia. Also exciting was for a link to the story to show up on the front page of reddit, AKA “The front page of the internet,” and as of now the story has 17.2 thousand upvotes on the r/technology subreddit. Needless to say, people feel that CATALOG’s efforts are an intriguing peak at what’s to come with DNA data storage and computing technologies!

We also received some nice coverage, including a video interview with Hyunjun, on the website of MIT’s Industrial Liaison Program. CATALOG is proud to be part of the STEX25 group of companies!

Our vision for making DNA-based storage a reality in 2019.

During this year’s SynBioBeta, we announced our collaboration with Cambridge Consultants in building our PartyBus. When completed early next year, we will be able to encode information in DNA at a speed of 1TB/day, for about 1/1,000,000 the cost of what’s been possible before. We are speaking with companies now for early-access pilot projects in 2019. If you would like to learn more, please get in touch!

We’ve been featured in some awesome articles that cover our progress. A few of them are available here, but visit our website for the full list.

Our Progress

Since our 1kb proof of concept last November, we have been working on reaching our next milestone of encoding a Mb by Demo Day. We are well on our way to achieve that goal. We have also made huge progress in all three layers of our development: coding, biochemistry, and implementation. This includes a 5X more efficient coding scheme, DNA-based parity-checking mechanism, and the use of acoustic liquid handlers, just to name a few. Also, we’re really close to reaching our goal for the seed round!


You can witness the CATALOG platform at work in this video. For small amounts of information, such as a sentence, we are able to use robotic liquid handlers and just a couple of plates of DNA oligos to get the job done. The robot is hard at work encoding the message, “how catalog encodes information”. This is how we encoded our New Year’s greetings into DNA. (Link)

Some good news from CATALOG

We encoded our first 1kB!

Friends, we are happy to announce that last week, Catalog used its platform technology to encode its first piece of data into DNA. For this proof-of-concept experiment, we chose to immortalize the poem “the Road Not Taken” by Robert Frost. In doing this we shattered our major milestone of encoding a 1kB within a month of starting bench work at IndieBio. We are now actively improving upon our encoding scheme, which will allow us to encode more data while taking fewer pipetting steps. We are also working on automating and miniaturizing the process to bring us closer to our goal of encoding 1MB by demo day.

Visit to the Internet Archive

Internet Archive is a non-profit digital library, with the mission to archive and provide universal access to all of humanity’s knowledge. On 10/26, Internet Archive turned 20 and we had a blast at the birthday party held in their beautiful San Francisco headquarters. In a 1996 video shown at the party, the founder of Internet Archive explained his ambitious vision of storing all 10 terabytes of the internet. They have since grown to store many petabytes of data, in their famous Petabox systems. Dear Internet Archive, we love what you are doing, you are a great friend, and we would love to archive your data in DNA for you!
