AI Agent Development Services

Custom AI systems for the work between your tools.

We design and build custom AI systems that take over specific operational tasks: lead routing, content generation, data syncing, reporting. Your team stops spending time on work that follows rules and starts spending it on work that requires judgment.

AI Development Services: Overview

Eastern Standard’s AI Agent Development service designs, builds, and deploys custom AI agents that execute multi-step business workflows across your existing software stack. Each engagement begins with a workflow audit and produces a working agent integrated into your tools, plus documentation your team can use to operate and maintain it.

This might be a fit if your team…

  • Spends time every week on recurring processes that move data between tools
  • Has a workflow that follows a pattern but involves too much variation for Zapier or Make
  • Is curious about where AI could realistically help, but isn’t sure where to start
  • Has ideas for AI but doesn’t have the in-house engineering bandwidth to build them
  • Is in the middle of a redesign or platform migration and wants AI considered as part of the architecture

What you walk away with

  • A documented workflow audit with prioritized automation opportunities
  • A working AI agent integrated into your stack (CRM, content tools, data warehouse, etc.)
  • Defined human review checkpoints and escalation paths for edge cases
  • Handoff documentation so your team can operate the system without us

Typical engagement shape

  • Workflow audit: 2 to 3 weeks
  • Single-workflow agent build: 4 to 8 weeks after audit
  • Multi-workflow or multi-system builds: scoped after audit
  • Pairs with AI Rollout & Team Enablement when structured adoption support is needed

Not sure where to start? That’s exactly what the workflow audit is designed for. You don’t need to come in with a specific agent in mind. Just bring a sense of where your team is losing time. Talk to us about an audit →

The problem

You know AI should help here. The hard part is figuring out where to start.

Most organizations we talk to have the same situation: the tools are in place, the data is mostly there, the team is capable. What’s slowing things down is the work happening between those tools. The copy-paste between the CRM and the content platform. The Slack thread that has to happen before a lead gets assigned. The weekly report that someone rebuilds from scratch every Monday.

Off-the-shelf automation handles the simplest version of this work. If X happens, do Y. But the moment a workflow involves variable inputs, conditional logic, or a small judgment call, those tools fall over and the work goes back to a person.

That gap, between “too complex for Zapier” and “not worth hiring for,” is where AI agents are doing real work. The hard part isn’t the technology. It’s knowing which workflow to start with, what the agent should actually do, and how to keep a human in the loop where it matters.

40%

of enterprise applications will feature task-specific AI agents by 2026, up from less than 5% in 2025. The organizations seeing results are the ones that identified specific, high-friction workflows and built tightly scoped systems around them.

Our approach

We map your workflows, then build the agents that run them.

We don’t start with a technology recommendation. We start with how your team actually works: the steps in each process, the tools that connect them, the decisions that have to be made, and the places where time gets lost.

  1. 01

    Map

    We sit with the people who actually do the work today and document the current process end-to-end: the tools, the handoffs, the decision points, and where time gets lost.

  2. 02

    Scope

    We identify which parts of the workflow are good candidates for an agent, which parts are better handled by traditional automation, and which parts should stay with a person.

  3. 03

    Build

    We build the agent inside your existing stack and integrate with the tools you already use. You see working software in two-week sprints, not a big reveal at the end.

  4. 04

    Hand off

    We deliver the working system with documentation, defined human review checkpoints, and escalation paths for edge cases. Your team operates it from there.

Built into your stack, not on top of it

We work in the tools you already use rather than asking your team to adopt anything new. If traditional automation is the right answer for part of the workflow, we use it.

Humans stay in the loop where it matters

Every agent we build has defined checkpoints before irreversible actions and an escalation path for cases the agent shouldn’t handle alone. Oversight is part of the design, not an afterthought.

Examples of AI workflows

01 · Marketing

Marketing automation

Agents that monitor campaign performance, draft personalized follow-ups, and adjust spend based on real-time data, without manual review at every step.

02 · Content

Content engines

RAG systems that synthesize your SME interviews, brand history, and source documents into production-ready drafts grounded in your actual expertise.

03 · Data & CRM

Data routing & CRM logic

Agents that manage lead routing, inter-platform syncs, and conditional logic between tools like Salesforce, HubSpot, and Jira, eliminating the manual glue work between systems.

04 · Engineering

Software engineering & testing

Coding agents that assist your development team with boilerplate generation, automated test creation, code review, and debugging, integrated into your existing repos and CI pipelines.

Claude AI implementation

The Claude tools we deploy

Claude is the foundation of most of the systems we build. Three products do most of the work: one for engineering, one for everyday team operations, and one for design and prototyping.

01 · Engineering

Claude Code

Agentic coding for production systems. We use Claude Code to build, refactor, and maintain the integrations that connect your CRM, content platforms, data warehouse, and internal tools, on your team’s stack and inside your repositories.

  • Custom agent development and tool-use scaffolding
  • Codebase audits and refactors with full context
  • Integration work across HubSpot, Salesforce, Jira, and Drupal/WordPress

02 · Operations

Claude Cowork

A shared workspace where your team works alongside Claude on real day-to-day operations: drafting, research, synthesis, reporting. We configure Cowork around your specific workflows so adoption is immediate, not theoretical.

  • Role-specific workspace setup for marketing, ops, and content teams
  • Knowledge base and source-document grounding
  • Defined guardrails, escalation paths, and review checkpoints

03 · Design

Claude Design

Rapid design and prototyping with Claude’s visual model. We use it to move from brief to working interface in hours, generating brand-aligned mocks, working prototypes, and front-end scaffolds against your design system.

FAQ

Common questions about agentic workflows.

What kinds of workflows at your organization are good candidates for agentic AI?
The best candidates are workflows that are high-volume, rule-based, and currently requiring a human to execute steps that don’t actually need human judgment. Common examples: routing inbound leads based on attributes, syncing data between platforms, generating first-draft content from source documents, monitoring and reporting on campaign performance, and managing multi-step approval or notification chains. If your team is spending significant time doing the same logical sequence of steps repeatedly, it’s worth examining.
How is agentic workflow engineering different from standard automation tools like Zapier or Make?
Standard automation tools handle simple trigger-action sequences: if X happens, do Y. They work well when the inputs are predictable and the logic is linear. Agentic AI handles workflows where the inputs vary, the steps aren’t always the same, or the process requires something resembling a judgment call: evaluating content quality, deciding how to route an edge case, synthesizing information from multiple sources before acting. We use standard automation where it’s the right tool and AI agents where it’s not.
What happens if the AI agent makes an error or produces bad output in your workflow?
This is the most important design question in any agentic system, and we address it in the architecture phase. Every system we build has defined checkpoints where a human reviews output before irreversible actions are taken. We also establish escalation paths: the AI handles the volume, a human handles the edge cases. The goal is to remove humans from the parts of the process that don’t require them, while keeping them on the parts that do.
Do you need to use specific platforms or tools to build an agentic workflow?
No. We build around your existing stack. The audit phase identifies what you already have, how it connects, and where the gaps are. We’re not locked to any particular platform or framework. We select the right tools for your specific workflow, your team’s technical capacity, and your budget. If you have strong opinions about specific tools, we work within those constraints.
How long does it take to build a custom AI agent for your organization?
It depends on the complexity of the workflow and the number of system integrations involved. A focused, single-workflow agent typically takes four to eight weeks from audit to production deployment. More complex systems with multiple workflow threads and integrations take longer. We scope every engagement explicitly after the workflow audit, so you know what you’re committing to before development begins.
What does an engagement cost?

Every engagement is scoped after the workflow audit, but we can give you ranges. A workflow audit on its own is a fixed-fee engagement, typically two to three weeks. A focused single-workflow agent build, including the audit, generally lands in the mid-five-figure range. Multi-workflow systems, custom integrations across many platforms, or builds that include design and front-end work scale up from there.

The audit is the right starting point in almost every case. It produces enough specificity that we can quote a build with confidence, and it gives you a deliverable you can act on even if you decide not to move forward with us.

What does the engagement actually look like, week by week?

The audit phase involves working sessions with the people who actually do the workflow today, interviews with the stakeholders who own the surrounding systems, and a written audit document at the end. That document maps the current process, identifies where agents make sense versus where they don’t, and proposes a build scope.

If we move into a build, we work in two-week sprints with a weekly check-in. You see working software as it gets built rather than waiting for a big reveal at the end. Your team is involved throughout, both because that’s how we make sure we’re building the right thing, and because adoption goes better when the people who’ll use the system helped shape it.

What happens after the agent is deployed? Do you maintain it?
We hand off the working system with documentation your team can use to operate and maintain it. For most engagements, that’s the end of the formal build. If you’d like ongoing maintenance, model upgrades, or expansion to additional workflows, we offer a retainer arrangement. We don’t push it as a default because most teams are capable of running a well-documented agent themselves once it’s deployed.
How do you handle data security and access to our internal systems?
We work within whatever security framework your organization already has. That usually means signing your standard agreements, using your authentication and access controls, and integrating with your existing logging and monitoring. We don’t ask for broader access than the agent actually needs to do its job, and we document every system the agent touches as part of the handoff. For organizations with stricter compliance requirements (HIPAA, SOC 2, FedRAMP, etc.), we scope those constraints into the audit phase before architecture decisions are made.
Will this replace people on our team?
That’s not what we design for, and it’s not how our clients use these systems. The teams who get value from this work are the ones using agents to absorb the high-volume, low-judgment portion of their workload, so the people on the team can spend more time on the parts of the job that actually need them. If a workflow is being done by a team that’s already stretched thin, an agent gives them room to breathe rather than a pink slip to deliver.
What if we don’t know which workflow to start with?
That’s a common starting point and it’s what the workflow audit is designed for. You don’t need to come in with a specific agent in mind. You need to come in with a sense of where your team is losing time, and we’ll work through it with you to find the workflow that’s the best first build: highest impact, lowest risk, most learnable for the next one.

Is your team losing hours every week to recurring workflows?

If any of the below sounds familiar, an audit conversation is a good place to start. You don’t need a fully scoped project in mind. Just bring a sense of where the work is piling up.

We can help:

Teams with a clear, recurring workflow problem that costs time and creates errors.

Organizations mid-redesign that want AI capability built into their architecture from day one.

Companies that have AI ideas but lack the internal engineering bandwidth to execute them.
