Translating Deep Scientific Expertise Into Accessible Protein Sequencing

From our founding in 2013, we’ve been focused on democratizing protein sequencing so that every day scientists can generate deeper insights faster. By solving complex biological, chemical, and mechanical problems, we are removing barriers to scientific discovery and bringing protein sequencing to every bench.

Our History

Inspired by Ion Torrent’s success at shrinking next-generation sequencing technology into a benchtop instrument, Jonathan Rothberg founded Quantum-Si to bring the same semiconductor technology to protein sequencing.

That was in Guilford, CT, back in 2013. Fast forward to today and we now have over 1,000 patents issued and applications pending, plus a groundbreaking single-molecule protein sequencing technology platform, PlatinumTM.

Along the way, we solved critical challenges around sensitive and unambiguous amino acid detection, blending biology, chemistry, and semiconductor technology to help biologists see what other approaches cannot deliver. We also set the stage for a revolution in how scientists understand biology and build new treatments for disease by making single molecule protein sequencing accessible to every lab everywhere.

We are now entering a new phase of our development as a company. Starting with an initial public offering in June 2021 (QSI on the NASDAQ) and continuing with a new product development and operations facility in San Diego, CA, in 2022, we have entered a period of rapid growth. Through this expansion, we will be able to fuel a new era of biology, the post-genomic era, where biologists accelerate basic scientific insight and biomedical advances through the power of next generation protein sequencing.
