mbag.ai runs on the same platform as Mailbuttons, the Agent Mail API for regulated and compliance-heavy AI work. mbag.ai is the consumer-facing front end onto that same infrastructure: same JMAP cluster, same policy engine, same audit log, same operator.

# The company

mbag.ai is operated by Code Cutter Limited, registered in England & Wales, company number 08453060, registered office at Unit 96 The Maltings Business Centre, Stanstead Abbotts, Ware, Herts, SG12 8HG.

# The person

Mailbuttons — and mbag.ai — is a small, focused engineering operation. The procurement review is conducted with the person who wrote the code.

Richard Halldearn, Founder. A decade engineering trading systems and market-risk platforms at Morgan Stanley, Deutsche Bank and Credit Suisse, followed by CTO and CEO roles at PE-backed technology companies. MSc Computer Science, Imperial College London. Now runs codecutter.io, a technology advisory practice for PE firms and portfolio boards — and is currently embedded on an AML modernisation programme at a UK retail bank.

Mailbuttons is the email-infrastructure problem he kept hitting in compliance-heavy AI work — built from the inside of regulated-finance projects, not from a startup-blog reading list.
