Agentic AI development services in Boston

As Agentic AI Development Services serving Boston, we build agents that bring real rigor to the paperwork itself, working through a workflow and acting inside your real systems instead of stopping at the first case that does not fit a template. Every credential and every piece of infrastructure stays under your own control, so none of this depends on us once the build is handed over.

Built for teams at a specific inflection point.

Where are you right now?

01

Ready to go further

Most of the routine data handling already moves without anyone watching each step, but a record that breaks pattern still needs someone to sort it out by hand. A system that can resolve that variation on its own is the piece still missing.


An agent that handles the exceptions as part of the process it already runs.

02

Evaluating agentic AI

A candidate keeps coming up in conversation, trial data review, KYC checks, patient scheduling, but whether an agent is actually the right fit has not been tested yet. What is needed first is a grounded assessment before committing budget.


A direct recommendation and a realistic scope, in either direction.

03

Ready to build

The proof of concept holds up in a limited setting, but real volume, genuine edge cases, and a team relying on it every day are a different bar entirely. What comes next needs a partner who can close that gap.


A live system with decision trails, accuracy figures, and support behind it.

Agentic AI development services in Boston: what gets built

From a single scoped agent to a coordinated multi-agent platform, we design, build, and operate across the full spectrum. Start where the value is clearest and expand from there.

Custom AI Agent Development

Every engagement narrows to one agent built around one workflow: a clear limit on what it can decide unassisted, the specific tools it is cleared to use, and an escalation path for whatever sits outside that limit.

Single-agentMulti-step reasoningTool use

Every engagement narrows to one agent built around one workflow: a clear limit on what it can decide unassisted, the specific tools it is cleared to use, and an escalation path for whatever sits outside that limit. The agent is proven against your own data before it ever reaches a live queue.

Agentic AI Consulting and Strategy

Some workflows are not ready for an agent yet, and this step is where that gets determined honestly.

FeasibilityArchitectureRoadmap

Some workflows are not ready for an agent yet, and this step is where that gets determined honestly. Whether agentic AI development services fit a given process gets settled here, before any commitment to build.

Multi-Agent System Development

Research, compliance, and clinical data rarely sit in a single system, so a process spanning all three usually calls for several agents working together.

Agent orchestrationLangGraphCrewAI

Research, compliance, and clinical data rarely sit in a single system, so a process spanning all three usually calls for several agents working together. This pillar is the layer that connects them: handoffs, shared context, and escalation rules that keep the whole network traceable.

Agentic Workflow Automation

The agent reads the instruction, works through whatever variation the task presents, retries on its own when something fails, and pauses for a person only when a genuine decision is on the line.

An agent that cannot reach your systems only exists on paper. This pillar covers wiring it into CRM, ERP, and the research or clinical platforms common across Boston's biotech, asset management, and hospital systems, with the integration scoped out before any sprint begins.

RAG and Knowledge Base Systems

Every answer traces back to real protocols, policies, or scientific literature, each one carrying a citation.

Every answer traces back to real protocols, policies, or scientific literature, each one carrying a citation. That is the line between an answer a reviewer can verify and one they simply have to trust.

What we have built, across categories.

Types of agents we build for Boston teams

What has actually shipped, sorted by category.

Where research rigor meets paperwork that used to need a scientist's time.

Clinical trial data agents

Pull trial data from multiple sources, check it against protocol requirements, and flag discrepancies for review.

Scientific literature research agents

Pull relevant findings from internal and published research against a specific question, summarising results for a researcher to verify.

Regulatory submission support agents

Assemble FDA submission documentation against a checklist and flag missing items before a deadline.

Where accuracy and a defensible audit trail are the baseline.

KYC and fraud signal agents

Verify identity and transaction data, check it against fraud indicators, and flag or clear cases automatically.

Investment reporting agents

Pull performance and holdings data across systems, generate client reports on schedule, and flag data that does not reconcile.

Compliance monitoring agents

Run continuous checks against regulatory thresholds and data handling requirements, surfacing alerts a team will actually act on.

Where patient volume outpaces what any front desk can manage manually.

Patient scheduling and intake agents

Coordinate appointments, verify insurance details, and route exceptions to staff without a manual call.

Clinical documentation agents

Extract and structure information from clinical notes, checking it against required fields before it reaches a record.

Patient engagement agents

Handle routine scheduling and billing questions, going well past what a chatbot alone typically covers.

Shaped around how each industry here actually works. regulated BFSI.

Built for how Boston's industries actually operate

Biotech and Life Sciences

Clinical trial data review, scientific literature research, and regulatory submission agents built for the density of biotech and life sciences companies clustered around Kendall Square and the Seaport.

Asset Management and Financial Services

KYC, investment reporting, and compliance monitoring agents built for the scale of assets under management that Boston's asset managers and custodians handle. Fintech apps built with AI raise a related set of decisions whenever AI touches a regulated financial product.

Healthcare Systems

Patient scheduling, clinical documentation, and engagement agents sized for the patient volume that Boston's hospital systems and medical centers process daily.

Higher Education and EdTech

Student query handling, adaptive learning support, and research administration agents for the university-affiliated institutions and edtech companies concentrated around the city's universities.

Insurance

Claims intake and triage, policy document extraction, and renewal workflow agents sized for the volume that comes with Boston's insurance head offices.

How we build, every step of the way.

How we design and operate production agents

The engineering discipline behind every build.

Schedule a call

Agent scope and boundary definition

The first output of any engagement is a written boundary: what the agent decides on its own, what needs a person's review, and what gets logged either way. That boundary, along with a confidence threshold, exists before development begins.

  • LangGraph
  • LangChain
  • CrewAI

Accuracy benchmarking on your real data

Using a sample pulled from your own records, a target accuracy gets agreed before a single line of production code is written, so the standard is fixed in advance rather than discovered later.

  • Amazon Textract
  • Azure Document Intelligence
  • Custom fine-tunes

Integration layer with visible error handling

Retry counts and failure rates from every connector land somewhere your team can review directly, rather than sitting in logs only the people who built them can interpret.

  • Temporal
  • Prefect
  • Custom event bus

Evals and continuous improvement loops

Evaluation checks run continuously beside the agent from day one, catching any decline in accuracy internally, well before a reviewer or patient would otherwise have to flag it.

  • Promptfoo
  • Braintrust

Why teams pick us for this.

Why Boston teams choose Zethic

Process first, then the agent

The workflow gets mapped in full before any framework enters the conversation. Reversing that order is how an agent ends up shaped by a tool's limits instead of the process it is actually meant to run.

You own the agent layer

Credentials, the vector store, and every piece of prompt logic live exclusively in accounts you control, on foundations built to be portable. Operating, changing, or transferring this work never depends on keeping us involved.

Accuracy engineered in, not bolted on

Every agent ships with a benchmark, a fallback path, and monitoring already built in, not added after a mistake surfaces. That gives your team direct visibility into performance long before a client or regulator would ever need to raise it.

Senior engineers on every engagement

One engineer carries the work from the first scoping conversation through the final sprint, whether that touches a single pillar or the broader AI development practice. There is no stage where responsibility shifts to someone less experienced.

How we deliver

The work moves through four phases, from a mapped process to a live agent, on a schedule that actually holds.

Book a call

{ 01 }· 1 to 2 weeks

Workflow assessment and agent architecture

Every input, output, decision point, and system connection gets documented; the same groundwork any AI development services engagement needs before a build starts. The output is a ranked scope, a reference architecture, and a timeline that stays fixed.

{ 02 }· two-week sprints

Build and integrate

Extraction logic, reasoning, integrations, and monitoring come together across short sprints, each one closing with a working demo on a staging setup that mirrors production closely.

BuildIntegrate

Accuracy benchmarking and UAT

Real data runs through the agent, results get measured against the benchmark set earlier, and every edge case gets closed out before production traffic ever touches it.

FAQs for Agentic AI development services in Boston

An agent works through several steps on its own, calls outside tools, and makes decisions based on context to reach a goal without a person guiding each one. A chatbot answers a single question; an agent carries the process itself, exceptions included, the same shift now underway across agentic AI in the US.

The workflow gets understood before a framework gets chosen, not the other way round. The same senior engineers stay on the account from the first call through handover, with no rotation to a different team midway.

A single-agent build typically runs four to eight weeks from assessment to production. A multi-agent system takes eight to sixteen weeks, and the assessment phase settles a firm number before anything gets committed.

Yes. Agents pull and structure trial data from multiple sources, check it against protocol requirements, and assemble regulatory documentation against a checklist, matched to the standards biotech and life sciences teams already work under.

Yes. Agents are built to track which requirement set applies to a given piece of data, whether that is the Massachusetts data security regulation or a federal rule, and keep a clear, reviewable record of how each decision was reached. Data privacy compliance principles apply regardless of jurisdiction.

The client does, entirely. Agent definitions, prompt logic, vector stores, credentials, and cloud infrastructure all sit in the client's own accounts, on foundations a team can run and change without needing outside help. We apply the same approach in our Agentic AI development services in Chicago.
