AI Systems Built for Your Business
Privacy, Performance & Precision
Automation, custom models, and secure hosting — delivered through an AI-native stack tailored to your operations.
Why FifthSuit
Privacy-First by Design
We avoid storing raw proprietary documents whenever possible and favor embeddings and client-owned storage.
Full-Stack AI Systems
From strategy and automation to custom models, RAG, and hosting—we handle the complete AI infrastructure.
Infrastructure-Agnostic
We can deploy into your cloud, your on-prem environment, or dedicated hardware—whatever meets your needs.
Focused on Outcomes
Our work is measured in saved time, reduced costs, and new capabilities—not just "AI for AI's sake."
Boutique & High-Touch
You work directly with a technical partner, not a generic agency assembly line.
AI Strategy & Roadmapping
We assess your current operations, systems, and data, then identify where AI can actually make a meaningful difference. You get a prioritized roadmap that aligns AI projects with your business goals—not just experiments.
Automation & Workflow Integration
We automate repetitive workflows using tools like n8n and custom integrations across your existing stack—CRMs, email, databases, Slack, Notion, and more. The result is faster execution, fewer errors, and clear visibility into what's happening.
Custom Model Development
We fine-tune language and other AI models (LLMs, LoRA/QLoRA, and similar techniques) so they match your brand voice, domain expertise, and internal processes. Instead of generic responses, you get a model that behaves like a trained team member.
Private Knowledge Systems (RAG)
We build retrieval-augmented generation (RAG) systems that let your AI securely access your documents, spreadsheets, and internal knowledge. Your data stays private while your team gains powerful, context-aware assistance.
Secure Hosting & Infrastructure
We design and operate private model and embedding hosting—on your cloud, on-prem, or dedicated infrastructure—so you're not tied to public APIs. We focus on clear data boundaries, security best practices, and operational reliability.
Ongoing Maintenance & Support
Models drift, data changes, and workflows evolve. We stay with you after launch, monitoring performance, refreshing embeddings, updating models, and evolving the system as your business and tools change.
Who We Work With
We partner with teams that need AI systems they can trust, not just another chatbot.
Teams with complex internal processes that could benefit from automation.
Organizations with privacy, compliance, or regulatory constraints.
Companies exploring custom models or private knowledge systems.
Leaders who want to move beyond public APIs and build durable AI capabilities.
How We Work
A collaborative process from discovery to ongoing evolution
Discovery & Assessment
We start with a conversation and a structured assessment of your systems, processes, and data. The goal is to understand what you're trying to achieve and what constraints matter—regulation, privacy, latency, cost, and so on.
Outcome: Clear understanding of opportunities and constraints
Design & Prototype
We design an AI architecture that fits your environment—covering automation, custom models, RAG, and hosting where appropriate. We validate assumptions quickly with targeted prototypes.
Outcome: Validated approach and technical roadmap
Build & Deploy
We implement the agreed solution, integrate it with your tools, and deploy into your chosen environment (your cloud, on-prem, or dedicated infrastructure). We focus on reliability, observability, and maintainability.
Outcome: Production-ready AI systems
Maintain & Evolve
After launch, we monitor performance, update embeddings and models, and adjust workflows as your business changes. We prefer long-term partnerships over one-off projects.
Outcome: Continuously improving operations
Example Transformations
A few ways AI systems from FifthSuit can change how your team works.
Automating recurring reporting across CRMs, spreadsheets, and internal tools.
Building a private knowledge assistant that answers questions from your internal documents and policies.
Fine-tuning a model to match your company's voice and domain expertise for support, sales, or internal communication.
Migrating from public AI APIs to private or client-controlled infrastructure for better privacy and cost predictability.
When Privacy & Control Matter
Many organizations face real constraints: legal privilege, HIPAA compliance, financial regulations, or proprietary processes that provide competitive advantage.
Public AI APIs don't always meet strict privacy requirements or support the unique capabilities some organizations need. We help you decide when private infrastructure makes sense—and when it doesn't.
When it does, we build custom models hosted on infrastructure you control, with clear data boundaries and security practices that fit your requirements.
Common Use Cases
- ★Legal firms with client privilege requirements
- ★Healthcare organizations with HIPAA constraints
- ★Financial services with regulatory requirements
- ★Businesses with unique domain expertise
- ★Organizations seeking competitive differentiation
How We Handle Your Data
Security and privacy are built into how we work, not added as an afterthought.
Minimal data handling: We work with embeddings and derived artifacts whenever possible, rather than storing full documents.
Client-side processing: When we do process raw data, we design flows so data is processed in your environment or stored only transiently.
No cross-client training: We never use your data to train models for other clients.
Your infrastructure: We can deploy entirely within your cloud, on-prem, or in dedicated environments with clear boundaries.
Our Approach
How we help you build effective AI systems
AI-Native Architecture
We help you decide when to enhance existing processes and when it makes sense to design something new from the ground up. Sometimes incremental is right; sometimes transformation is needed.
Strategic Partnership
We combine technical depth with operational experience. We understand how organizations make decisions, implement change, and measure success—so we can help you navigate the journey.
Privacy & Control
When privacy matters, we deploy on your infrastructure with clear data boundaries. You maintain control and aren't dependent on changing platform terms or pricing.
