Alder is the AI employee for accounts receivable. Most late B2B invoices aren't refusals. They're stuck behind a stalled approval, a rejected AP portal submission, a missing PO number, a short-pay, or an AP contact who left. Alder finds out which, and clears it.
Collections: follows up in the original email thread with the person who actually releases payment, and tracks every promise to pay.
AP portals: submits invoices to Coupa, Ariba and custom customer portals, and fixes rejections, missing POs and changed AP contacts.
Disputes and short-pays: researches each one and assembles the supporting evidence.
Alder works on the systems finance teams already use: Gmail, Outlook, Teams, Slack, NetSuite, SAP, QuickBooks, Stripe, Coupa, Brex, Mercury, Chase and Plaid.
The finance team stays in control.
Alder was founded in 2025 by former Uber engineers, is based in San Francisco, and is backed by Y Combinator.
