AI AGENT DEVELOPMENT · USA
AI Agents That Run Your Business While You Sleep
Your competitors are automating the work that costs you 20 hours a week. FactoryJet builds custom AI agents — for customer support, sales, operations, and more — that work around the clock, integrate with your existing tools, and cost fixed-price vs a US AI agency.
AI AGENT IN ACTION
3,200 support tickets handled automatically — in the first month.
Customer asks about order status → agent checks Shopify → replies in 4 seconds
Lead fills out contact form → agent qualifies → books a demo to your calendar
Invoice arrives by email → agent extracts data → logs to QuickBooks → notifies AP
All three workflows run 24/7, without a single new hire.

AI EXPLAINED
What Is an AI Agent, and Why Does Your Business Need One?
A chatbot answers questions. An AI agent takes action. It connects to your tools, reads inputs, makes decisions, and completes multi-step workflows — without a human directing every step.
Most business owners have heard of ChatGPT. But a chatbot and an AI agent are fundamentally different things. A chatbot sits in a window and responds to typed questions. An AI agent — built on the same underlying technology — can actually do things: check your inventory, send a customer an update, update a CRM record, book a meeting, draft a contract, process a document, and then report back on what it did.
The result is a piece of software that behaves more like a capable new team member than a search bar. It works 24 hours a day, handles the volume spikes that overwhelm your human staff, and never calls in sick. And unlike hiring, it costs a fixed amount to build and runs at near-zero marginal cost afterward.
FactoryJet has been building software for small and mid-sized businesses since 1999. We understand what operations look like inside a 10-person company — the manual data entry, the repetitive emails, the spreadsheet that someone has to update every Friday. Those are exactly the workflows AI agents are designed to eliminate. We've delivered AI systems for e-commerce brands, real estate teams, SaaS companies, professional services firms, and healthcare practices across the US.
How an AI Agent Operates
Receives a trigger
Email, form submission, scheduled time, webhook, or API call fires.
Reads your data
Queries your CRM, inventory system, calendar, or any connected tool.
Takes action
Sends a reply, books a meeting, updates a record, or processes a document.
Reports back
Logs every action with a full audit trail and notifies your team.

THE PROBLEM
Your competitors are automating. Most small businesses are still doing it by hand.
The gap between companies that have deployed AI and those that haven't is growing fast — and it shows up in response times, operational costs, and customer experience. The businesses winning right now aren't bigger. They're faster.
20–30 hours/week lost to manual work
The average SMB owner spends more than half their working week on tasks that AI can handle: answering the same support emails, updating spreadsheets, chasing invoices, and manually entering data between systems. That time doesn't come back — until you automate.
Slow response times are costing you deals
Studies show 78% of customers buy from the first business that responds to their inquiry. If your competitor has a sales AI that follows up in under 60 seconds and you're relying on a team member to check email twice a day, the math is not in your favor.
US AI agencies are priced for enterprise, not SMBs
A mid-tier US AI development agency quotes $40,000–$150,000 for a production AI system. That's before the retainer. FactoryJet delivers the same engineering quality at fixed-price — because our experienced team has the same skills with a radically different cost structure.

THE US AI MARKET
AI Agents Are No Longer Optional for US Small Businesses
The conversation has shifted from 'should we explore AI?' to 'how fast can we deploy it?' According to McKinsey's 2025 State of AI report, 96% of enterprises plan to expand AI agent adoption in the next 12 months. The businesses moving fastest aren't the Fortune 500 — they're the agile SMBs who can adopt new tools without a six-month procurement process.
FactoryJet has served small and medium businesses in Austin, Miami, Denver, Nashville, Portland, Charlotte, Raleigh, Tampa, and across the US since 1999. We understand what the inside of a 10-person business looks like — and we know exactly where AI creates the most leverage: customer response speed, back-office automation, and reducing the manual labor that burns out your best people.
The businesses we build for aren't buying AI because it's trendy. They're buying it because they ran the math: a $15,000 Growth AI platform that saves 25 staff hours per week pays for itself in under 12 weeks — and keeps paying forever.

WHY FACTORYJET
We're not a US AI agency with a fancy website. That's the point.
We're a 25-year-old software company that has built 500+ production systems for real businesses. The AI we build doesn't live in a slide deck — it runs in production and does actual work.
Speed without cutting corners
A US AI agency has account managers, project coordinators, and a sales team to keep fed. We don't. When you brief us, an engineer reads it — not an account manager. That's why our timelines are weeks, not quarters.
SMB domain depth, not startup theory
We've built for e-commerce brands, law firms, healthcare practices, real estate teams, and SaaS companies since 1999. We know where the actual complexity lives in a 15-person business. We build for that reality — not for a Y Combinator pitch.
You own everything. Always.
No vendor lock-in, no SaaS subscriptions, no proprietary platforms you can't leave. We deliver the full codebase, all API keys, and documentation. If you outgrow us, you walk away with an asset — not a dependency.

Talk to the founderWhat Are AI Agents
What exactly is an AI agent, and how is it different from a chatbot?
A chatbot answers questions. An AI agent takes action. A chatbot sits in a window and responds to what you type. An AI agent — built on the same large language model technology — connects to your tools, reads inputs from multiple sources, makes decisions, and completes multi-step tasks without you directing every move. It can check your inventory, update a CRM record, send a follow-up email, process a document, and report back on what it did — all in sequence, automatically.
What kinds of tasks can an AI agent handle for my business?
AI agents are best at high-volume, rule-based work that currently eats your team's time: answering the same customer questions repeatedly, routing and triaging support tickets, qualifying inbound leads, processing invoices and documents, updating records across systems, scheduling appointments, sending follow-up sequences, and generating reports from raw data. If your team does something more than a few times a day and it follows a pattern, an AI agent can probably handle it.
What types of AI agents does FactoryJet build?
FactoryJet builds six core types: Customer Service AI (24/7 support bots that handle tickets, answer questions, and escalate to humans), Sales AI (lead qualification, outreach sequencing, follow-up automation), Operations AI (invoice processing, scheduling, internal workflow automation), Data & Analytics AI (reporting agents that pull, clean, and summarize business data on demand), Voice AI (phone-based agents that handle inbound calls and book appointments), and Document Processing AI (agents that read, classify, extract, and route contracts, forms, and PDFs).
Which AI models power these agents — Claude, GPT-4o, or something else?
We use Claude (Anthropic), GPT-4o (OpenAI), Gemini (Google), and open-source models like Mistral and LLaMA depending on your workflow, cost sensitivity, and data privacy requirements. We don't have a preferred vendor — we pick the right model for each use case. For orchestration we use LangChain, LangGraph, CrewAI, n8n, and Make.com. Most clients don't need to think about this; we handle model selection and explain the reasoning.
Process & Timeline
What does the development process look like from start to finish?
We follow five stages: Discover (we map your workflows, data sources, and goals), Architect (we design the agent logic, integrations, and guardrails), Build (we develop and connect everything), Train & Test (we run the agent through real scenarios and tune its behavior), and Deploy (we launch, hand off, and train your team). Every stage ends with a demo so you see progress weekly and can course-correct before we build further.
How long does it take to build and deploy an AI agent?
Simple single-workflow agents — a lead qualifier, a support bot, an invoice processor — typically go from kickoff to launch in 2–3 weeks. Multi-workflow platforms with CRM integrations and dashboards take 4–6 weeks. Enterprise systems involving multiple agents, complex data pipelines, and compliance requirements run 8–12 weeks. We give you a firm timeline after the discovery session, not before, because scope drives everything.
Will I see progress during the build, or is it a black box until launch?
Weekly demos throughout — no exceptions. After every stage we show you what's been built and how it behaves. You can give feedback, adjust the logic, and reprioritize features before we move to the next stage. Most clients find that seeing the agent working early changes their thinking about what's possible, and we build in room for that.
What happens after the AI agent launches?
Every engagement includes a 30-day post-launch support window. During that period we fix bugs, tune the agent's behavior based on real usage, and run a training session with your team. After 30 days, you can continue on a monthly retainer for ongoing optimization, or manage it yourself — the dashboard is built for non-technical operators and all code and API keys are yours.
Pricing & ROI
How much does it cost to build a custom AI agent?
FactoryJet's AI agents start at $5,000 for a focused single-workflow agent (Starter tier). Most small businesses need the Growth tier at $15,000, which covers multiple interconnected agents, CRM integrations, a management dashboard, and a 30-day support window. Enterprise platforms with multi-agent orchestration start at $25,000. All prices are significantly lower than comparable US AI agencies.
Why is FactoryJet fixed-price, milestone-paid?
Predictability. Fixed-price means every project is scoped upfront — no hourly billing, no scope-creep invoices, no surprise change orders. Milestone-paid means you pay against delivered work, not against time. Our lean senior-only team delivers production-grade architecture, code, and handover with no layers of account management between your brief and the engineer building it. You brief an engineer; that engineer builds it. You get full code ownership at handoff and the quote you sign is what you pay.
What is the typical ROI on an AI agent investment?
The most common return comes from labor hours recovered. A customer support agent handling 70% of tickets at $15,000 replaces hundreds of hours of manual work per month. A lead qualification agent that responds to every inbound lead within 60 seconds typically increases conversion rates by 20–35% — response speed is the single biggest driver of lead close rates. Most clients see payback within 3–6 months of launch.
Are there ongoing costs after the build is complete?
Yes, two types: API usage costs (the AI model fees, typically $50–$300/month for most SMB use cases depending on volume — these go directly to model providers, we don't mark them up) and optionally a FactoryJet retainer if you want ongoing optimization or new feature development. The retainer is optional; many clients self-manage after the handoff.
Technical & Integrations
What software and platforms can an AI agent connect to?
We integrate with most business software via API: CRMs (Salesforce, HubSpot, Pipedrive, Zoho), e-commerce (Shopify, WooCommerce, Magento, BigCommerce), communication tools (Slack, Gmail, Outlook, Twilio for SMS and voice), project management (Notion, Airtable, Asana, Monday.com), databases (PostgreSQL, MySQL, Supabase, Firebase), and document storage (Google Drive, Dropbox, Box). If your platform has a REST API or webhook support, we can connect to it.
Do I need a technical team to manage the AI agent after launch?
No. We design every agent with a non-technical operator in mind. The management dashboard lets you see what the agent is doing, review flagged items, adjust thresholds, and pause or resume workflows — all without touching code. We also include a recorded training walkthrough specific to your agent. If something breaks or needs updating because a connected platform changed its API, you contact us and we fix it.
Can you build AI agents for niche or highly specialized workflows?
Yes — most of what we build is custom. We've built agents for insurance claim intake, legal document review, HVAC dispatching, wholesale reorder management, clinical scheduling, and SaaS onboarding sequences, among many others. The underlying architecture is the same; the workflow logic, prompts, data connections, and guardrails are built specifically for your process. We start with a discovery session to map the workflow before writing a line of code.
What happens if we switch software platforms after the agent is built?
We architect agents with modular integration layers, meaning the agent logic is separated from the connector code. Swapping one CRM for another typically means updating the integration module, not rebuilding the agent from scratch — days of work, not months. We document all integration points during delivery specifically so that future changes are straightforward.
Trust & Results
Will my business data be safe when using an AI agent?
Yes. We architect with data privacy as a baseline requirement, not an afterthought. We use API-level integrations (not screen scraping), enforce least-privilege data access so the agent only touches what it needs, and implement full audit trails on every action. For regulated industries — healthcare, legal, finance — we can deploy private LLM setups that process your data without sending it to third-party model providers. All data flows are documented during delivery.
What happens if the AI agent makes a mistake or gives a wrong answer?
Every agent we build includes confidence thresholds (if the model isn't sure, it escalates to a human rather than guessing), guardrails on high-stakes actions (the agent requests human approval before sending emails, processing payments, or updating records it shouldn't touch autonomously), and a full action log so you can audit exactly what the agent did and when. No AI system is 100% accurate — responsible design means errors are surfaced and correctable, not silent.
Can an AI agent replace my customer support team?
It shouldn't, and we'd advise against framing it that way. AI agents work best as the first line of support — handling 60–80% of routine tickets, order status questions, and common queries automatically, around the clock, without wait times. They escalate anything nuanced, emotionally sensitive, or outside their confidence threshold to your human team. Most clients don't reduce headcount; they redirect their team to higher-value customer relationships instead of repetitive queries.
How is FactoryJet different from hiring a US AI development agency?
Three differences that matter: pricing model (fixed-price and milestone-paid — every project scoped upfront with no scope-creep invoices, backed by 25+ years serving US businesses), speed (no layers of account management between your brief and the engineer building it), and SMB depth (500+ small business projects since 1999 — we understand the operational reality of businesses your size, not just enterprise AI theory). We also won't pitch you an AI agent when a simpler automation would do the job.
Do you have results or examples from businesses similar to mine?
Yes. We've built AI agents for e-commerce brands that reduced support ticket volume by 70%, for service businesses that cut lead response time from hours to under 60 seconds, and for operations teams that eliminated 30+ hours per week of manual data entry. We're happy to share relevant case studies during a strategy call — and if we haven't worked in your specific industry, we'll tell you that upfront rather than pretend otherwise.
