Technology advisory, security & AI development coaching
Field of Green helps ambitious teams build and run technology well: from Discovery Sprints and fractional CTO/CISO leadership to ISO 27001, AI-accelerated development, and regulated medical-device software and assurance.
What we do
Discovery Sprints
A fixed-scope, lean sprint to bootstrap a new product, feature, or service, prototypes, not promises, with thin slices of working prototypes.
Learn more →Fractional CTO / CISO
Senior technology and security leadership, on tap, strategy, architecture, and governance without a full-time hire.
Learn more →ISO 27001 Consultancy
Pragmatic information-security management for small businesses, from gap analysis to a certification-ready ISMS.
Learn more →AI Development Training & Coaching
Help your engineers ship faster with AI-assisted development, without sacrificing quality, security, or craft.
Learn more →Medical-Device Software & SaMD
Take software through ISO 13485 and the Software as a Medical Device lifecycle, including AI/ML-enabled features, to CE/UKCA and FDA.
Learn more →Security & Cryptography for Medical Systems
Information governance and applied cryptography for clinical data, zero-knowledge identity, enclave-backed audit ledgers, and AI-in-the-loop governance.
Learn more →How we work
We bring two decades of hands-on engineering and security leadership to teams that need senior judgement without a full-time hire. The work is practical and outcome-led: clarify the strategy, de-risk the architecture, put the right governance in place, and leave your people more capable than we found them.
Engagements are deliberately small and senior. You get someone who has built and secured real systems, not a deck and a handover, and who measures success by what your team can do after we leave.
