Ten years solving enterprise
computing's hardest problem
We built IONATE to modernize the mission-critical legacy systems that have run the world's largest banks, insurers, and governments for decades — without stopping the business while we do it.
The Problem Is Real
Legacy modernization isn't a niche IT project. It's the defining infrastructure challenge of the next decade.
The risk of staying on legacy is no longer theoretical. Outages, compliance failures, and talent gaps are accelerating. The question isn't whether to modernize — it's how to do it without breaking the business.
Our Story
Built from the ground up to do what no one else could.
Founded
IONATE was founded with a singular focus: solve one of computer science's biggest problems — modernizing any legacy system to cloud-native architectures efficiently, safely, and at scale. Ten years of R&D later, we have the structured knowledge and proven platform to do it.
Startup Exchange Member 2016–2021
IONATE was a member of the MIT Startup Exchange program, connecting us with cutting-edge research and a global network of innovators at the frontier of enterprise technology.
Partnered at Scale
We are globally partnered with leading system integrators — NTT Data, Accenture, Deloitte, Kyndryl, and more — serving financial services, insurance, retail, and government customers across three continents.
How We Work
The D.A.T.E.D. Process — five structured phases from assessment to production, with no big-bang risk at any stage.
Discover
SOTERIA scans 100% of your legacy estate — every COBOL program, JCL job, CICS transaction, copybook, and dependency — producing complete structured metadata before a single line of code is touched.
Analyze
Business rules are extracted from conditional logic, hotspots identified, and every program complexity-scored and risk-ranked. You see exactly what you have and what it takes to modernize — no estimates, no sampling.
Train
Domain-specific knowledge models are applied to your estate. The system learns your code's unique patterns, business rules, and integration points — not generic COBOL patterns — so transformations preserve your exact logic.
Execute
APPDATE's battle-tested transpilers convert COBOL, JCL, VSAM, and CICS to cloud-native Java microservices, Spring Batch, and REST APIs — with 99.999% accuracy and full business rule preservation.
Deploy
KÍRKĒ orchestrates phased, controlled releases — business operations continue uninterrupted throughout. Cloud-agnostic delivery: on-prem, AWS, Azure, or GCP. Full observability and SRE tooling from day one.
KÍRKĒ — The Platform That Runs the D.A.T.E.D. Process
D.A.T.E.D. is our delivery methodology. KÍRKĒ is the product that orchestrates and manages every phase of it — six operational stages from discovery to continuous delivery, with no big-bang cutover at any point.
Any legacy stack. One process.
We handle three distinct legacy portfolios — all converging to the same modern, cloud-native target.

Your AI teammate for legacy modernization
MIRA is the intelligence layer behind every step of the D.A.T.E.D. process — built on 10+ years of structured legacy knowledge, not a generic LLM wrapper. She analyzes your estate, extracts undocumented business rules, and runs transformations autonomously in your own infrastructure.

Who Trusts Us
Enterprise leaders across financial services, logistics, healthcare, and government.
Financial Services & Insurance
Davivienda reduced time-to-market by 80%. CVP Brasil and Hapvida/GNDI completed transformations at 50% of projected timelines with 60% annual cost savings — with full business continuity throughout.
Government & Public Sector
SERPRO — Brasil's Federal Revenue (IRS) — modernized its national-scale ADABAS/Natural platform to cloud-native microservices, serving hundreds of millions of citizens without service interruption.
Logistics & Retail
UPS converted JCL batch processing to Spring Batch microservices. UNFI and others have transformed core supply chain and ERP systems underpinning billions in annual revenue.
Built by Practitioners
Our team has done this before — at companies where the stakes were just as high.
Deep Enterprise Pedigree
IONATE's founders and engineers are alumni of Akamai, IBM, Oracle, and Apple — veterans who have built and scaled mission-critical systems across the world's largest enterprises.
20+ Years Domain Expertise
Our team brings over two decades of hands-on experience with legacy systems, AI/ML, cybersecurity, and cloud infrastructure — not consulting abstraction, but real engineering depth.
Multiple U.S. Patents
Our co-founders hold multiple U.S. patents in identity cloud architecture, security discovery, and modernization technology — the same IP that powers the IONATE platform.
Global Delivery
Engineering, sales, and customer success teams across San Francisco, Redwood Shores, México, Kraków, São Paulo, and Santiago — covering every major market we serve.
Core Principles
The values that guide every decision we make.
Relentless Customer Focus
Every product decision, every partnership, every line of code starts with the customer outcome we're driving toward.
Own the Action
We don't observe problems — we take responsibility and act. Every team member is empowered and expected to move the needle.
Do Things That Don't Scale
We invest deeply in early customer relationships and handcraft solutions before automating — because trust is built one transformation at a time.
Together We Can
Modernization at enterprise scale requires deep collaboration — with customers, partners, and every member of the IONATE team.
