Nebula Genomics Shutdown, Explained

Nebula Genomics, the consumer whole-genome-sequencing company co-founded by Harvard geneticist George Church, shut down its consumer service on February 5, 2025. The website went offline, new orders stopped, and the relative-matching service that had built up over several years ended. Existing customers had a defined window to download their raw data before the consumer service fully wound down.

Timeline

2016: Nebula Genomics was founded with George Church as a co-founder. The pitch that distinguished it from the autosomal SNP genotyping tests was whole-genome sequencing for consumers, meaning a much larger and more detailed underlying data file than the genotype chips used by 23andMe or AncestryDNA.

2018 through 2023: Nebula sold whole-genome sequencing at several price tiers. 30x whole-genome sequencing was offered around $299 at various points, with a low-pass sequencing option around $99 used as an entry tier. A subscription attached to ongoing report updates and tools.

2024: consumer whole-genome volume across the category remained small. Marketing slowed and product updates became less frequent, which the trade press flagged as indicators of trouble.

February 5, 2025: Nebula Genomics shut down its consumer service. The site stopped processing new orders. Active customers received notice of a window to download their raw data and any reports they wanted to keep. The DNA matching feature ended with the service.

What it means for your data

Two pieces of context are worth holding in mind.

A consumer service shutdown is not the same as a data breach. Companies routinely spell out, in their privacy policies, what happens to user data if the service ends. The choices generally include returning the data to the user, deleting it, transferring it to a successor entity, or some combination, governed by the consent that was originally given. We cover the general pattern in what happens to DNA data if a company shuts down.

Whole-genome sequence files are larger and richer than genotype files. A 30x whole-genome file is on the order of tens of gigabytes, versus a few megabytes for the genotype text file produced by an SNP chip test. If you tested with Nebula, the local copy of that file is meaningfully more useful than a genotype file would be, and it can be uploaded to a range of third-party analysis tools.

What you can do

If you were a Nebula customer and you did not act inside the original download window, your first step is to check the email account you used at signup for any final-notice messages with continuing download instructions or successor-service options. The archived shutdown notice on the Wayback Machine is the public record of what was communicated.

If you have a local copy of your raw Nebula data, treat it like the irreplaceable file it is. Back it up. Our guide on how to download your raw DNA data covers the general best practices for storing and re-uploading these files.

If you want continued whole-genome sequencing as an active product in 2026, the practical replacement we point readers at is Sequencing.com, which operates a whole-genome offering plus an app marketplace and accepts raw data uploads. Pricing and sequencing depth tiers change, so confirm the current options on its site before ordering.
