What We Build

Everything You Need to Run AI Agents at Scale

A complete GenAI platform—infrastructure, orchestration, prompts, and governance—built for your specific workflows and handed over entirely.

Production-Ready AI Infrastructure

Kubernetes or serverless deployment in AWS, GCP, or Azure. Terraform-provisioned, fully documented, and designed for scale. Your ops team can manage it from day one.

Intelligent Agent Orchestration

LangChain, CrewAI, or AutoGen-based workflows. Multi-agent systems with tool-use, memory, and reasoning. MCP integrations for enterprise connectivity.

Domain-Optimized Prompts

Battle-tested prompt engineering tailored to your use cases—with chain-of-thought reasoning, safety guardrails, brand voice customization, and fallback strategies.

Evaluation & Quality Assurance

Automated testing harnesses, hallucination detection, output quality scorecards, and regression testing for prompt changes. Deploy with confidence.

Security & Governance Framework

Data residency controls, audit logging, role-based access, and compliance-ready architectures. Built for regulated industries from the ground up.

Complete Knowledge Transfer

Full source code, architecture documentation, runbooks, and hands-on training for your team. We build it. You own it. You run it.

The AI Platform Dilemma

Your AI experiments are scattered. Your options are limited.

The Problems with Current Approaches

Most companies face the same frustrating choice: vendor lock-in or endless DIY complexity.

SaaS AI Locks You In

Generic chatbots with opaque pricing, limited customization, and data you don't control. Every integration deepens your dependency.

DIY Takes Forever

Your engineers spend 12-18 months stitching together LangChain, vector databases, and infrastructure—instead of shipping product.

Security & Compliance Gaps

Public APIs, unclear data handling, no audit trails. Your CISO is nervous. Your compliance team is blocking deployment.

Prompts Are an Afterthought

Most consultants build infrastructure but hand you generic prompts. Your agents hallucinate, miss edge cases, and embarrass your brand.

Our Solution

Own Your AI Platform. Run It Your Way.

theorem.agency builds production-grade AI platforms deployed in your cloud—using open-source components, battle-tested architectures, and finely engineered prompts. You get the source code, the infrastructure templates, the documentation, and the training to run it independently.

8-12 weeks from discovery to production

A proven engagement model that delivers working AI agents—not endless discovery phases.

100% source code ownership

Complete transfer of all code, infrastructure templates, documentation, and training materials. No hidden dependencies.

Open-source stack, no vendor lock-in

Built on LangChain, CrewAI, or AutoGen. FastAPI backends. Kubernetes or serverless. Your team can extend it without us.

Your cloud, your data, your rules

Deployed in your AWS, GCP, or Azure environment. Full data residency control. Compliance-ready from day one.

Use Cases

AI Agents That Solve Real Business Problems

We've built agents across support, sales, operations, engineering, and compliance. Here's what they do.

Customer Support Copilot

Resolve 30-50% of tickets without escalation. Route complex issues with full context. Maintain brand voice and safety guardrails. (40% ticket deflection · 25% faster resolution)

Sales Enablement Agent

Generate first-pass proposals, competitive positioning, and case study recommendations. Accelerate time from lead to proposal. (60% faster proposal generation)

Operations Automation

Process invoices, onboard employees, generate compliance reports. Workflow agents that follow your exact business rules. (Audit-ready decision logs)

Engineering Productivity

Code review suggestions, documentation generation, runbook assistants. Agents that match your team's standards and conventions. (30% faster review cycles)

From Discovery to Production in 8-12 Weeks

A proven engagement model that delivers working AI agents—not endless discovery phases.

Week 1-3: Discovery & Design

We identify your highest-impact AI use cases, map data flows, and define success metrics. You get a detailed architecture blueprint and prompt strategy before we write a line of code.

Week 4-10: Build & Engineer

Infrastructure deployment, agent orchestration, and deep prompt engineering. We build, test, and iterate on your agents until they meet your quality gates—not generic benchmarks.

Week 10-12: Harden & Hand Over

Security hardening, evaluation frameworks, documentation, and training sessions. Your team learns to operate, optimize, and extend the platform independently.

Ongoing: Optional Advisory

Monthly or quarterly optimization cycles—prompt A/B testing, failure analysis, capability expansion. No lock-in; available when you need us.

FAQs

Frequently Asked Questions

Answers to common questions about our AI platform development services.

How is this different from hiring an AI consultancy?

Most consultancies optimize for ongoing billable work. We optimize for handover. You get complete source code, documentation, and training. Our success is measured by whether you can run and extend the platform without us.

What tech stack do you use?

We build on proven open-source: LangChain, CrewAI, or AutoGen for orchestration; Kubernetes or serverless for deployment; Terraform for infrastructure-as-code; FastAPI for APIs; PostgreSQL/pgvector or Pinecone for vector storage. Everything is customized to your cloud and requirements.

How long does a typical engagement take?

8-12 weeks from discovery to production for a single-use-case platform. Larger multi-agent systems or enterprise deployments may take 12-16 weeks. We scope tightly and deliver incrementally—you see working agents early.

What about ongoing support after handover?

We offer optional monthly or quarterly advisory retainers for prompt optimization, A/B testing, and capability expansion. But you're never locked in—your team can operate independently from day one.

Can you work with our existing cloud infrastructure?

Yes. We deploy in AWS, GCP, or Azure—whichever you use. We integrate with your existing IAM, networking, and security policies. No separate vendor environments required.

How do you handle data security and compliance?

Everything runs in your cloud, under your control. We build with data residency, audit logging, and role-based access from the start. We've delivered platforms for healthcare, financial services, and regulated industries.

What if we've already started building internally?

We frequently augment internal efforts. We can review your architecture, take over prompt engineering, or accelerate specific components. Our goal is to get you to production faster—not to replace your team.

How much does it cost?

We provide detailed proposals after a discovery conversation. It depends on scope, complexity, and enterprise requirements. No hourly billing—fixed scope, fixed price.
