The system of record
Stop running your portfolio on a spreadsheet
Renewal dates scattered across a dozen registrars, no clean cost basis, offers lost in your inbox. Sourdough is one source of truth for everything you own.
No registrar logins
Import a CSV from any registrar. No API keys, no shared passwords — your whole book in minutes.
Renewal alerts before they lapse
A renewal ladder warns you weeks out and daily in the final stretch — checked against live registry data, not your notes.
Real cost basis & P&L
Track what you paid, what renewals cost, and what you sold for — true return across the whole portfolio.
Offers & listings, tracked
Log inbound offers, track listings, and set your own valuation on every name, so no deal gets lost in your inbox.
How it works
From spreadsheet to system of record in minutes
No registrar logins, no setup call. Import, and Sourdough does the rest.
Import your portfolio
Upload a CSV from any registrar or add names by hand. Sourdough pulls live WHOIS/RDAP data on each automatically.
Watch every renewal
One dashboard, every expiry date, sorted by what is due next — with alerts before anything can lapse.
Know your P&L
Cost basis, renewal spend, offers, and sale proceeds roll up into real profit and loss across your book.
Put your whole portfolio in one place
