Software for the recurring work businesses shouldn't still be doing by hand.
REVALLUX is a software company that looks for real, repeated operational problems in B2B — finance operations, compliance, revenue operations — and builds focused, automated tools to remove them.
Labs — problems we're investigating
E-invoicing from Stripe (Peppol, XRechnung, Factur-X, KSeF)
Check what the EU e-invoicing mandates mean for you, and whether a customer is reachable on Peppol.
Lead forms that silently stop delivering
Check where your website's lead forms actually send data — HubSpot, Pipedrive, Salesforce, HighLevel, Zapier, Make and more.
Stripe payouts that don't match your books
Compare a Stripe payout export with your bank or accounting export — in your browser, nothing uploaded.
Security questionnaires for small SaaS teams
Generate a first-draft answer set for common security-review questions from a few facts about your setup.
How we work
We publish free tools first and only build a product when enough people show — by using a tool and asking to be notified — that the problem is worth solving. We don't buy email lists, we don't send cold email, and we'll only contact you if you ask us to.
