Agents do the repetitive tasks, people direct, review and control

Governed from day one

Approval gates on high-risk actions, an action-level audit trail, and a kill switch—designed before the agent is built, not bolted on after. Governance is the design constraint, not the review step.

Humans in every loop

The agent takes the repetitive majority and escalates the moment real judgment is needed. Confidence thresholds and escalation paths are defined up front, and the escalation share is measured weekly.

Custom agent solutions, not white-labeled

Every agent is built for your use cases and business processes, on and across whatever stack you already own—including the systems staff currently bounce between to get one request done—vendor-neutral, on open standards, extensible by your team.

Case Studies

Our client impact in action

AI call auditor automates 99% of reviews

A regulatory compliance firm partnered with FullStack on a proof-of-concept for an AI system that reviews calls for potential SEC violations, scoring accuracy and confidence on every transcript. Reviewers went from reading every transcript to adjudicating the 1% the system flags—an estimated 5,500 labor hours and $232,000 annually of review capacity returned to the team.

AI document processing cuts costs by 50%

A logistics provider's legacy document system, estimated at over $1 million annually, was inefficient and unscalable. FullStack built a scalable AI solution that reduced processing times by 75% and cut costs in half while maintaining accuracy and reliability.

FullStack's own delivery organization

FullStack is running this program on its own delivery organization first—client zero for the curriculum and the labs—with a documented roadmap and real distance to cover. We'll publish the before-and-after honestly, including what needed rework.

Due Diligence First

Prioritize the workflows with high business value

Every custom AI agent development engagement opens with a one-week fixed-fee Process Mapping: we mine the work alongside the people doing it, rank workflows by ROI and feasibility, and pick the top two or three.

First workflow live in 6–8 weeks*

Including shadow mode inside that window, so the agent proves itself on real transactions before it handles any on its own.

Proven in shadow mode first

Agents run real cases scored against the people doing the same work today. Only agents that hit the accuracy and escalation targets graduate. What doesn't generalize gets killed.

Not every workflow qualifies

Agent-ready work has volume, repetition, digital data availability, and low judgment density. If a process fails those tests, the process mapping will say so.

Data grounding is usually in scope

52% of organizations cite data quality as the biggest barrier to agent deployment. If your data isn't reachable or trustworthy—including data scattered across the systems staff already re-key between—that work comes first, and we'll tell you during mapping rather than mid-build.

Frequently Asked Questions

How much does AI agent development cost?
The cost of AI agent development depends on the workflow: its volume, how many systems the agent has to touch, and whether your data is ready to use. That's why every engagement starts with a one-week, fixed-fee Process Mapping. We rank your workflows by ROI and feasibility, so you know where the business value is before you commit to a build. After launch, the agent is tracked against clear success metrics (cost per transaction, cycle time, and escalation rate), all measured against the baseline set during discovery.
How do you keep AI agents secure and under control?
Governance is designed in before the agent is built. Every agent gets approval gates on high-risk actions, an action-level audit trail, and a kill switch. That's the core of enterprise-grade security for agents: robust AI agent architectures where every action is traceable and every risky step needs a human sign-off.
Can a multi-agent setup handle complex workflows?
Yes. When one workflow spans several systems or steps, we design an orchestration graph that splits the work across multiple agents, each with its own task, permissions, and escalation path. Running multiple AI agents this way keeps each one simple to test and govern, instead of relying on one agent that tries to do everything.
Do you offer AI agent consulting, or only build agents?
Both. Some clients want us to build AI agents end to end. Others already have teams working in n8n or LangChain, and we pair our engineers with theirs, keep what's working, and add the production discipline around it. Either way, the result is custom agents built for your processes, on your stack, and extensible by your team.
How do you know an agent is ready for production?
Every agent runs in shadow mode first, handling real cases that are scored against the people doing the same work today. Only agents that hit the accuracy and escalation targets graduate, and anything that doesn't generalize gets killed. That's how we build intelligent AI agents that hold up in production, not just in a demo.
