Private AI systems,
built the way you'd build them
if you had the time.
Coresyn builds production-grade AI platforms for companies that want to own their infrastructure, their data, and their intelligence layer. Document intelligence, workflow automation, agentic systems, and operational AI, deployed on your cloud or ours, running the models you choose.

Practical AI infrastructure
for real operations.
We don't do slide decks or proof-of-concepts that never ship. Every engagement produces working software deployed into production, on your infrastructure, integrated with your systems, owned by you.
Private AI Platforms
Self-hosted LLM infrastructure with hybrid search, retrieval-augmented generation, and agentic reasoning. Your models run inside your VPC. Your data never leaves your network. Works with any model provider or fully offline with open-source models.
Document Intelligence
Turn contracts, invoices, reports, and operational documents into queryable knowledge with cited answers. Multi-format ingestion, structured extraction, semantic chunking, and citation tracing built on production-grade retrieval pipelines.
Workflow Automation
Replace manual processes with automated pipelines. Connect cloud storage sources, monitor for changes, extract structured data, route it to the systems that need it. Webhooks, integrations, and AI augmented decision flows orchestrated end to end.
SaaS Replacement
Audit your current SaaS stack and build ground up replacements that you own. CRM, quoting, finance, operations, all tailored to how you actually work. Private, integrated, and designed around your processes instead of generic templates.
AI Gateway & Model Routing
One API for every model. Route requests across OpenAI, Anthropic, Google, and self-hosted open-source models based on task, cost, and latency. Token-level metering, per-team budgets, automatic failover, and prompt versioning. Swap providers without touching application code.
Agentic Systems
AI that doesn't just answer questions — it executes multi-step workflows autonomously. Agents that plan, use tools, query databases, call APIs, recover from failures, and escalate to humans when the stakes demand it. Research pipelines, report generation, data reconciliation, all running hands-off.
Infrastructure you own.
Intelligence you control.
The AI tooling market is overwhelmingly built around vendor lock-in. SaaS products that hold your data hostage. APIs that change pricing overnight. Models that get worse without warning. Contracts that make it cheaper to stay than to leave.
Coresyn exists for companies that want a different arrangement. We build systems that run on your infrastructure, route through the models you choose, and store data in databases you control. If you need to change providers, you change providers. If you need to audit, you audit. If you need to go fully offline, you go offline.
We work with companies that have outgrown generic tools but don't want to staff an internal AI team. We become the engineering bench that delivers production systems in weeks, not the agency that bills hourly for another prototype.
Ownership over subscription
You own the codebase, the data, the deployment. No licensing traps or exit fees.
Private by architecture
Self-hosted models, isolated VPCs, encrypted storage. Not an afterthought.
Model-agnostic
OpenAI, Anthropic, Google, open-source. All supported. No vendor lock-in to any one provider.
Production, not prototypes
Every deliverable is production-grade from day one. No "we'll rebuild this later" technical debt.
Systems in production,
across industries.
A representative sample of the engagements we deliver. Some clients are public, others are anonymized for confidentiality. What they share is a need for private, production-grade AI infrastructure.
An international relocation and logistics company needed a single system that could think across their entire operation. We built a private AI platform with a unified knowledge layer over operational documents, policies, and regulatory filings — hybrid search, retrieval-augmented Q&A, all running inside their own VPC. Now expanding into quoting, booking, finance, CRM, and move management, consolidating three commercial SaaS products into one company-owned platform.
Document intelligence for professional services teams processing contracts, agreements, and policy documents at volume. The system ingests entire document repositories, extracts key terms, renewal dates, obligations, and deadlines, and makes everything searchable with cited, source-linked answers. Role-gated access controls. Integrates with existing document management and cloud storage.
A unified gateway that sits between applications and model providers — OpenAI, Anthropic, Google, self-hosted open-source. Routes each request based on task type, cost ceiling, and latency requirements. Token-level usage tracking, per-team budgets, automatic failover when a provider goes down, and a prompt versioning layer for A/B testing without redeployment. Swap providers without touching application code.
Multi-step AI agents that plan, execute, use tools, and recover from failures autonomously. The orchestration layer breaks complex tasks into sub-goals, manages tool calls across databases, APIs, and file systems, handles context across long-running workflows, and includes human-in-the-loop checkpoints where the stakes require it. Built for autonomous report generation, research pipelines, and multi-source data reconciliation.
Self-hosted document intelligence for organizations in regulated industries where data residency and audit requirements rule out cloud-based AI tools. Deployed inside the client's network with local inference via open-source models, encrypted credential storage, complete audit trails on every query, and identity integration through existing SAML and OIDC providers. No cloud dependency. Air-gap ready.
We build for clients.
We also ship our own.
TalkingDocuments
A production document intelligence platform built on the same architecture we deploy for clients. Upload any document format and get cited answers, structured data extraction, and automated workflows. Bring your own model, run on your infrastructure, or use our hosted version. Multi-tenant, enterprise auth, and on-prem ready.
Boring technology,
chosen deliberately.
Direct engineering.
No layers in between.
Scope it honestly
We start with what you actually need, not what sounds impressive in a proposal. Fixed price phases with clear deliverables. No ambiguity on what you're paying for and what you're getting.
Build it right
Production architecture from day one. The code that ships to staging is the code that goes to production. No prototypes that need rebuilding. No technical debt by design.
Hand it over
Your infrastructure, your codebase, your data. Full documentation. Your team can maintain, extend, or walk away at any time. No vendor lock-in to us or anyone else.
Stay in production
Optional retainer for maintenance, improvements, and new phases. Or a clean exit with transition documentation. Whichever suits the engagement, your call, not ours.
Let's talk about what
you need to build.
We take on a small number of engagements at a time to give each project full engineering attention. If you're exploring private AI infrastructure, document intelligence, workflow automation, or replacing a SaaS product you've outgrown, reach out.
Initial conversations are free and confidential. We'll tell you honestly whether we're the right fit for what you need, and if we're not, we'll usually know someone who is.
