I'm Sean, a mechanical engineer from Australia. My day job is machines: things that are designed, calculated, and tested, because when you make guesses, people get hurt. This mindset is the whole reason DatumFeed exists.
I kept watching parts sellers, including people close to me, lose their evenings or weekends to supplier spreadsheets. Every week the same thing: a supplier emails a ton of price files, and someone spends hours in Excel fixing part numbers, sanity-checking prices, and praying the import doesn't quietly wreck the store. Something as simple as a misplaced decimal goes live at $4.99 instead of $499, and the weekend is spent processing refunds.
What shocked me wasn't the mess, suppliers will always export chaos. It was that every import tool on the market just... trusts the file. They move all the data faithfully, garbage included. And the newest ones use AI to guess what your columns mean, which is a strange thing to do with somebody's prices.
So I built the tool I'd want standing between a messy file and a live store, and I gave it one stubborn rule from my engineering life: never guess. Every row is checked by fixed, inspectable logic. Anything the engine can't prove gets held for review with a plain-English reason and never touches your store. And because even careful systems should assume they'll be wrong someday, every sync is reversible in one click.
The rules DatumFeed lives by
No AI near your money
Part numbers, prices, and quantities are handled only by deterministic rules you could audit line by line. AI never writes, guesses, or "fixes" a value in your catalog. Ever.
Refuse, don't guess
A file the engine can't make sense of gets refused with a reason, not imported with a blind guess. These unproven rows wait for you while the good rows are uploaded right away.
Everything is reversible
Every sync records the exact prior state of everything it touches. Undo is one click away.
Small on purpose
DatumFeed isn't a venture-backed platform chasing twelve markets. It's one product, for parts sellers, built carefully.
If you sell parts online and you're tired of being your suppliers' unpaid data-entry department, I built this for you. Try the live demo on your worst files — it runs entirely in your browser, nothing gets uploaded, and if it makes you feel something, get on the list.
