Agentic AI development services in San Francisco

As Agentic AI Development Services serving San Francisco, we build agents that close the reconciliation gap directly, working through a workflow and acting inside your real systems instead of stalling at the first case that looks unfamiliar. 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

Routine work already moves through the system with barely any oversight, but the moment something breaks pattern, it lands on a desk and turns into a one-off task. What is missing is a system that can work through that variation on its own.


An agent that takes the exceptions on without a separate manual step.

02

Evaluating agentic AI

One workflow keeps coming up as worth automating further: investor reporting, clinical data intake, support triage, but there is no confirmed answer yet on whether an agent actually fits it. What is needed is an honest look before any budget gets committed.


A straight recommendation and a workable scope, whichever way it points.

03

Ready to build

The proof of concept holds up at a small scale, but it still has to survive full volume, real edge cases, and a team that will lean on it daily. What comes next needs a partner who can carry it that far.


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

Agentic AI development services in San Francisco: 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

Each build starts narrow: one agent, one workflow, with a hard limit on what it can decide by itself and a defined escalation path for everything past that limit.

Single-agentMulti-step reasoningTool use

Each build starts narrow: one agent, one workflow, with a hard limit on what it can decide by itself and a defined escalation path for everything past that limit. The agent gets proven against your own data before it ever touches a live queue.

Agentic AI Consulting and Strategy

Some processes are not ready for an agent, and saying so honestly is the whole point of this step.

FeasibilityArchitectureRoadmap

Some processes are not ready for an agent, and saying so honestly is the whole point of this step. Whether agentic AI development services suit a particular workflow gets settled here, before any commitment to build.

Multi-Agent System Development

Product, finance, and research records rarely live in one system, so a process that spans all three usually needs several agents working in coordination.

Agent orchestrationLangGraphCrewAI

Product, finance, and research records rarely live in one system, so a process that spans all three usually needs several agents working in coordination. This pillar is that coordination layer: handoffs, shared state, and escalation rules that keep the whole thing auditable.

Agentic Workflow Automation

Instructions get read, variation gets handled, failures get retried on their own, and a person only steps in where a genuine decision is required.

Full workflow executionEvent-drivenHuman-in-the-loop

Instructions get read, variation gets handled, failures get retried on their own, and a person only steps in where a genuine decision is required. The agent takes on the process itself, not a simplified version of it.

AI and System Integration

An agent that cannot reach a system is only useful on paper.

REST & webhookCRMERPLegacy connectors

An agent that cannot reach a system is only useful on paper. This pillar covers connecting it to CRM, ERP, and the specialised platforms running across San Francisco's startups, biotech labs, and financial firms, with the integration mapped out well before any sprint starts.

Answers trace back to real policies, research documents, and internal records, each carrying its own citation. That is the line between an answer a team can verify and one they simply have to accept.

What we have built, across categories.

Types of agents we build for San Francisco teams

What has actually shipped, sorted by category.

Where speed matters, but so does not breaking things later.

Investor reporting and pipeline agents

Pull metrics across systems, generate investor updates on schedule, and flag data that does not reconcile before a board meeting. Founders weighing whether to build this in-house or bring in help often look at SME digital transformation on a limited budget first.

Customer onboarding and provisioning agents

Set up accounts, permissions, and integrations for new customers without manual setup work.

Support triage and escalation agents

Read intent and urgency on inbound tickets, route to the right queue, and resolve routine cases without a handoff.

Where research data meets decisions that used to need a scientist's judgment.

Clinical trial data processing agents

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

Research document extraction agents

Extract findings, methods, and results from papers and lab reports, structuring them for downstream analysis.

Regulatory submission support agents

Assemble documentation against a checklist, flag missing items, and prepare submission packages for review.

Where accuracy and a defensible audit trail are the baseline.

Compliance monitoring agents

Run continuous checks against SOC 2, SOX, or GLBA requirements, surfacing alerts a team will actually act on.

Reconciliation and reporting agents

Pull data across systems, generate reports on schedule, and flag anomalies before a deadline.

Contract review agents

Pull key terms and risk flags from vendor and customer contracts, checking them against a standard playbook.

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

Built for how San Francisco's industries actually operate

Venture-Backed Startups and SaaS

Investor reporting, onboarding, and support agents for product teams scaling past what manual coordination can cover, a stage most funded startups in the city reach quickly.

Biotech and Life Sciences

Clinical trial data processing, research document extraction, and regulatory submission agents sized for the concentration of biotech and life sciences companies clustered around Mission Bay and South San Francisco.

Financial Services

Compliance monitoring, reconciliation, and reporting agents built around the SOC 2, SOX, and GLBA requirements that apply to financial firms headquartered in the city. Fintech apps built with AI raise a related set of decisions whenever AI touches a regulated financial product.

Enterprise Software

Ticket triage, reporting, and provisioning agents for the enterprise software companies concentrated in SoMa, built to sit alongside existing delivery workflows.

Healthcare

Patient intake, referral routing, and clinical documentation agents, built around HIPAA and data sensitivity as a starting requirement rather than something added on later.

How we build, every step of the way.

How we design and operate production agents

The engineering discipline behind every build.

Agent scope and boundary definition

Scope gets written down before anything else happens: what the agent handles on its own, what needs a person, and what gets logged no matter which way it goes. A stop-and-ask threshold is part of the build from day one, not bolted on once something goes wrong.

  • LangGraph
  • LangChain
  • CrewAI

Accuracy benchmarking on your real data

Before the first line of production code, a sample from your actual data gets pulled, and the target accuracy gets settled. That number exists before the build starts, not as something discovered after launch.

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

Integration layer with visible error handling

Every connector reports back on retries and failure rates into a single place your team can check without asking us. Integration health never sits buried where only the build team can see it.

  • Temporal
  • Prefect
  • Custom event bus

Evals and continuous improvement loops

Review checks run alongside the agent from the start, which means a dip in accuracy shows up before a customer or investor would ever need to point it out.

  • LangSmith
  • Promptfoo
  • Braintrust

Why teams pick us for this.

Why San Francisco teams choose Zethic

Process first, then the agent

A framework does not get picked until the workflow itself is understood. That ordering is deliberate: the architecture follows what is actually found, so the agent is built right the first time rather than reworked partway through.

You own the agent layer

Every credential, every line of prompt logic, and the vector store itself live in accounts that belong to you, built on open foundations. Nothing about running, changing, or handing this off to a different team depends on us staying in the picture.

Accuracy engineered in, not bolted on

An accuracy benchmark, a defined fallback, and monitoring exist from the day the agent ships, which means performance is visible internally long before an investor or customer would have reason to ask.

Senior engineers on every engagement

There is no rotation between the people scoping the work and the people building it, they are the same people throughout, whether the engagement sits inside one pillar or draws on AI as a broader discipline. Nobody hands this off to a junior bench after the first call.

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

Inputs, outputs, decision points, and system connections all get written down first; 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.

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.

Ways to work

Pick the engagement model that fits your team

Two ways to bring us in. Either one starts with the same senior engineers handling Agentic AI Development Services in San Francisco from week one.

Defined deliverable

Fixed-Scope Agent Project

One workflow, a fixed list of integrations, and acceptance criteria settled before work begins. The price stays fixed, the timeline stays fixed, and the finished system belongs to you outright, a reasonable way to try agentic AI solutions in San Francisco on a single process before committing further. Build versus buy is the underlying question either way, and this model answers it on one contained workflow first.

  • Fixed price and timeline
  • Milestone-based delivery
  • Detailed SOW and acceptance criteria
  • Change management with cost transparency
  • Post-launch optimisation window included

FAQs for Agentic AI development services in San Francisco

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.

Nobody picks a framework before the workflow itself is understood, and that ordering is deliberate. The same senior engineers stay on from the first call to the last sprint, with no rotation to a different team partway through.

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

Yes. Agents pull metrics from finance, product, and CRM systems, assemble investor updates on schedule, and flag data that does not reconcile before it reaches a board deck, built around the specific reporting cadence a startup already uses.

Yes. Agents extract and structure trial data from multiple sources, check it against protocol requirements, and flag discrepancies for review, matched to the data handling standards biotech and life sciences teams already work under.

Ownership stays with the client, fully. Agent definitions, prompt logic, vector stores, credentials, and cloud infrastructure live in the client's own accounts, on foundations a team can run and modify without needing outside help. We apply the same approach in our Agentic AI development services in Seattle.
