Modernize your legacy software.
Make it intelligent with AI.
SubNeta Inc turns aging Windows and desktop applications into modern web and mobile platforms - and builds production AI on top of them: retrieval-augmented generation over your data, LLM copilots, and generative AI automation. Quantum-safe security included. Experts only.
Trusted by enterprises across finance, healthcare, energy, and government · Expert-led delivery on every engagement · Confidential, complimentary initial assessment.
Why convert to web? Any device, anywhere - zero installs, one version for everyone.
Why convert to web? Role-based security, audit trails, and updates that ship to everyone instantly.
Why one web platform? One login, live data, every department finally in sync.

Why go mobile? Your team works where the work is - not where the desktop sits.
Retrieval-Augmented Generation. Your documents become answers - with citations, not hallucinations.
LLM & GenAI workflows. Unstructured input in, structured decisions out - at scale.
Quantum computing. Optimization and simulation problems classical hardware can't finish in time.

Quantum cryptography. Data encrypted today can be harvested now and decrypted later. Migrate before it matters.
Two focus areas. Three ways to start.
Not sure? Ask an expert →Most of our clients have the same two problems: business-critical software that is showing its age, and pressure to put AI to work. You can solve them separately or together - here is how to decide.
Modernize the application, then add AI
Best when the old system itself is the risk: unsupported frameworks (VB6, WinForms, WPF, Access), install headaches, no remote access, security audit findings, or the one developer who understands it is retiring.
- Rebuild as a secure web or mobile platform
- Data and workflows preserved, zero downtime
- AI features added once data is in a modern stack
Add AI to the systems you already have
Best when the software still works but people waste hours searching, re-typing, and reading. We connect AI to your existing databases and documents without touching the legacy code.
- RAG assistant over your SQL data and files
- LLM automation for documents, email, and tickets
- Results in weeks - modernize later if needed
AI-native modernization
Best when you are rebuilding anyway. We design the new platform with AI built in from day one - clean data models, APIs, and permissions that make RAG and automation straightforward instead of bolted on.
- One program, one architecture, one team
- AI copilots inside the new web and mobile apps
- Post-quantum-ready security by design
What SubNeta focuses on
See all services →Two frontiers, one team. We build the AI systems that change how your business runs today, and the quantum-ready foundations that keep it secure tomorrow.
Artificial Intelligence
Applied machine learning that solves a concrete business problem - prediction, classification, anomaly detection, decision support - engineered to run in production, not just a notebook.
RAG - Retrieval-Augmented Generation
Language models connected to your own documents, databases, and systems. Answers arrive with citations, permission-aware retrieval, and an evaluation pipeline that measures accuracy before and after launch.
LLM - Large Language Models
Model selection, fine-tuning, prompt engineering, guardrails, and cost control across Claude, GPT, Gemini, and open-weight models - hosted in your cloud or on-premises when data must not leave.
Generative AI (GenAI)
Agents and workflows that draft, summarize, extract, translate, and act - wired into the tools your teams already use, with human review where the stakes demand it.
Quantum Computing
Hybrid quantum-classical algorithms for optimization, simulation, and machine learning. We find where quantum offers a real advantage for your problem, prototype on today's hardware, and benchmark honestly.
Quantum Cryptography & Post-Quantum Security
Cryptographic inventory, risk ranking, and migration to NIST post-quantum standards (ML-KEM, ML-DSA, SLH-DSA), plus crypto-agile architecture so you can change algorithms again without rewrites.
Legacy ERP modernization for a Gulf Coast manufacturer
A 30-year-old system replaced with a cloud-native platform - cutting order processing time by 68% and unlocking AI-driven demand forecasting.
Industries we serve
See all industries →How we work
Discover
A free consultation to understand your goals, data, and systems - and to say honestly where AI or quantum will pay off.
Prove
A scoped proof of concept with success metrics agreed up front - accuracy, latency, cost, or risk reduction.
Build
Production engineering in short, visible iterations: evaluation, security review, and integration with your stack.
Operate
Monitoring, model and prompt updates, re-evaluation, and cost tuning - AI systems change after launch, and so do we.

Frequently asked questions
What does SubNeta Inc do?
SubNeta Inc modernizes legacy Windows and desktop applications into modern web and mobile platforms, builds enterprise AI systems including RAG, LLM applications, and generative AI automation, and prepares organizations for quantum computing and post-quantum cryptography.
What legacy applications can be modernized?
WinForms, WPF, VB6, Access, FoxPro, and other desktop applications can be converted to web platforms, and websites can be extended to mobile, with a phased migration that keeps the business running.
What is post-quantum cryptography migration?
A cryptographic inventory, risk assessment, and phased rollout of NIST-standardized algorithms such as ML-KEM and ML-DSA alongside classical algorithms, so data encrypted today cannot be harvested now and decrypted later.
How does an engagement start?
With a complimentary, confidential initial assessment, followed by a scoped proof of concept with success metrics agreed up front, then production build and ongoing operation.
Ready to put AI to work - and make your security quantum-safe?
