What we offer
End-to-end AI capabilities, delivered as a partnership.
From applied AI implementation to production operations, safety governance, cloud transformation and capital markets engineering — six practice areas, one continuous engineering operation.

●FLAGSHIP PRACTICE
01/FLAGSHIP PRACTICE
AI Implementations that work with your stack.
Your team shouldn't need to understand five different LLM APIs. We build the layer that connects them — RAG pipelines, agentic workflows and knowledge systems that work with your existing data and infrastructure.

●EU AI ACT · GDPR
02/GOVERNANCE
AI Safety & Security for production systems.
You've deployed an LLM. Now your compliance team wants to know: can it leak PII? Can someone jailbreak it? We answer those questions before they become problems.

03/OPERATIONS · 24/7
Support & MLOps for models that stay healthy.
Deploying a model is the easy part. Keeping it running, monitored, and retraining when the data shifts? That's where most teams struggle. We handle the ops.

Cloud Transformation, done by people who've done it.
Still running workloads on-prem that should have moved to the cloud three years ago? We've done it enough times to know where the pitfalls are — and how to avoid them.

BFSI Practice
Banking & insurance, delivered by specialists.
Beyond AI engineering, SustainSys is a change delivery partner for regulated financial institutions. We take on defined workstreams under our own statement of work — analysis, design, testing and implementation — delivered and managed by SustainSys consultants who already speak your domain, across digitalisation, modernisation and platform upgrade programmes.
On the insurance side: London Market digital trading — quote-bind platforms, delegated authority, bordereaux and claims data. On the banking side: Murex & treasury, regulatory reporting and payments modernisation.

Flagship products
Four products, one engineering rhythm.
Each one tackles a real bottleneck inside regulated enterprises — analytics, regulatory change, accounting, governance — built on the same secure, audit-ready stack.
★ NL2SQL Analytics — Flagship
Ask your database in plain English.
Your analysts shouldn't need to wait for engineering to pull a report. With NL2SQL, anyone on the team can type a question and get an answer — the platform writes the SQL, validates it, and returns results in seconds.
Designed for banks and regulated industries where data can't leave your network. Everything runs on-premise with 12-point security guardrails and a full audit trail. No cloud APIs, no data leaks.
Natural Language Querying
JOINs, aggregations & GROUP BY handled automatically
RAG-Powered Context
4 FAISS indexes for schema, glossary & relationships
12-Point Guardrails
SELECT-only, schema whitelisting, injection prevention
Self-Healing Queries

RegTech AI Solutions — New
Know what changed before the regulator does.
If your compliance team is still tracking regulatory changes in spreadsheets, this is for them. Our RegTech platform monitors 40+ regulatory sources across 11 jurisdictions and tells you exactly which EMIR, MiFIR or CFTC fields are affected — with citations back to the source document.
Built for the people who file the reports. A practical system that maps changes to your specific reporting fields and flags what needs action.

AccountIQ — On-Device AI
Your accounts, on your machine.
AccountIQ is an AI accounting assistant that runs entirely on your device. Your invoices, bank statements and tax records never leave your computer — not to a cloud server, not to an API. That's not a feature, it's the whole point.
It handles the work that eats up your week: VAT returns, bank reconciliation, year-end packs. Upload documents, ask questions in plain English, get answers with sources.

AI Compliance & Governance — New
AI systems that are regulator-ready.
End-to-end regulatory compliance support for AI projects, helping organisations assess legal obligations, implement governance controls, and maintain production-ready safeguards across the AI lifecycle. From regulatory impact assessments to ongoing monitoring, we turn compliance uncertainty into a clear roadmap.
Aligned with EU AI Act, ISO/IEC 42001 and NIST AI RMF — your AI systems designed for compliance and operated with the guardrails needed for regulatory and reputational risk reduction.

How we work
From discovery to production, in four phases.
A repeatable engineering rhythm that gets AI from idea to live, governed and observable — typically in eight to twelve weeks.
01
Diagnose
Two-week immersion. We map data, systems, regulatory exposure and decision points to identify where AI compounds value.
Week 1–202
Architect
Reference architecture, model selection, evaluation harness and governance plan — all aligned to your stack.
Week 3–403
Build
Engineering sprints with embedded teams. Pipelines, guardrails, CI/CD and observability shipped iteratively.
Week 5–1004
Operate
Production hand-off with 24/7 MLOps coverage, drift monitoring and quarterly model reviews.
Week 11+
Built for regulated industries
Security, governance & compliance — first-class, not bolted on.
Every system we ship is auditable end-to-end. We design for the most stringent regulatory regimes and operate with the rigour your security team expects.
