# Ankasum > Ankasum, by Devanka, is offer and reward software for US and Canadian banks and credit unions. An institution defines a bonus offer once; Ankasum reads it back in plain English, checks it before launch, routes it for maker-checker approval, works out who qualified from the institution's daily files, and writes the payout file the institution's core posts, with evidence recorded at every step. Facts on this site are as of 2026-11-12. Every page has a Markdown version at the same path with `index.md`; all pages in one file: [llms-full.txt](https://ankasum.com/llms-full.txt). Ankasum is made by Devanka (https://devankahq.com/). Demos and questions: hello@devankahq.com. Security reports: security@devankahq.com. Key points: - Ankasum never moves money. It writes a fulfilment file; the institution posts it and stays payer of record. - Each institution's data stays in its own isolated data plane, a dedicated AWS account in its own country. Only definitions, configuration, run metadata and totals over at least 10 customers reach Ankasum's shared control plane. - Deterministic rules decide eligibility and amounts. No identifiable customer or member data is sent to any AI model, and no model runs in the reward-integrity checks. - Ankasum releases or holds a payout; only a named person at the institution can refuse a reward. ## Start here - [Facts](https://ankasum.com/facts/index.md): short, dated, citable facts: what it is, who it is for, what it handles, data custody, AI use, contact. - [Home](https://ankasum.com/index.md): the problem, the four steps, how each team uses it, and what it runs. ## Product - [Who it's for](https://ankasum.com/who-its-for/index.md): how marketing, compliance, operations and IT teams use Ankasum, and the institutions it fits. - [How it works](https://ankasum.com/how-it-works/index.md): define, read back, test, approve, pay and record, with a worked checking-bonus example and its YAML definition. - [Reward integrity](https://ankasum.com/reward-integrity/index.md): leakage checked at design, before payment and after payment; who decides; what it is not. - [Security and data custody](https://ankasum.com/security/index.md): two planes, what crosses between them, operator access, evidence you can verify, AI and your data. ## Contact - [Contact](https://ankasum.com/contact/index.md): book a demo, email addresses for questions, security and privacy. ## Optional - [Devanka](https://devankahq.com/llms.txt): the company site's llms.txt, including security and trust, privacy and terms.
