# Tweezr > Tweezr is a system-intelligence platform for safe legacy change. It maps mainframe and heritage financial systems (COBOL, PL/I, CICS, IMS, DB2 z/OS, VSAM, IBM i RPG, Adabas/Natural) into a deterministic, queryable, cited model so engineering teams and AI tools know exactly what a legacy core does before changing it. Deployed on-premise by default for banks and insurers; no public API or developer program is published as of July 2026. Tweezr is a Techstars portfolio company, a member of the Banking Industry Architecture Network (BIAN), and a partner of 10x Banking. The product is distributed through AWS Marketplace and Microsoft AppSource. ## Company - [Website](https://www.tweezr.io/): System Intelligence for Safe Legacy Change - [Solution](https://www.tweezr.io/solution): Map, Understand, Answer — the platform's three integrated functions - [About](https://www.tweezr.io/about): Founders Ohad Kotler (CEO) and Ohad Zadok (CTO) - [Blog](https://www.tweezr.io/blog): Company blog - [Contact](https://www.tweezr.io/contact): Contact form ## Marketplaces - [AWS Marketplace](https://aws.amazon.com/marketplace/procurement?productId=prod-zkxhsqyxezl2c&sellerId=seller-t46r5hxjmitqa): Buy with AWS listing - [Microsoft AppSource](https://appsource.microsoft.com/en-us/marketplace/apps?search=Tweezr): AppSource listing ## Policies - [Terms of Use](https://www.tweezr.io/terms-of-use) - [Privacy Policy](https://www.tweezr.io/privacy-policy) - [Cookie Policy](https://www.tweezr.io/cookie-policy) ## API Evangelist Profile - [APIs.json](https://raw.githubusercontent.com/api-evangelist/tweezr/refs/heads/main/apis.yml): Machine-readable profile of Tweezr in the API Evangelist network
