AI Development Services, Custom AI Agents: Automation, and Marketing Tools
Most agencies will tell you to “use AI” without actually building anything with it. We do the opposite. We build the AI systems that save your team hours every day, custom agents, workflow automations, content pipelines, and integrated tools that plug into the software you already use.
If you are tired of buying yet another SaaS subscription that only solves 40 percent of your problem, we can build exactly what you need.
What we build
Custom AI agents
Agents that do actual work: research a prospect and write the outreach, summarize every meeting transcript into an action list, answer inbound sales questions 24/7 with access to your pricing and product data, or reconcile weekly metrics from multiple sources. We build them on whatever model fits the job, Claude, GPT, Gemini, and ship them integrated with the tools you already use.
Marketing automation with AI
Content pipelines that draft, optimize, and publish. Personalization engines that tune copy to segments in real time. Smart routing that decides which lead goes to which rep based on pattern-match from past wins. AI-powered A/B testing that chooses the next experiment automatically. All built around your existing marketing stack, not a replacement for it.
Workflow automations
Anything your team does every day that looks like “open one tool, copy data, paste into another tool, tweak, send”, we can automate. Usually with a mix of AI, Zapier/Make/n8n, and a bit of custom code. The average client saves 10-20 hours per week of manual work after a good automation pass.
Internal AI tools
Purpose-built AI tools for your team: a custom RAG system over your internal knowledge base, an AI-powered writing assistant trained on your brand voice, a pricing estimator that reasons through your quote logic, or a customer-support copilot. We build, host, and maintain them.
AI-powered websites and landing pages
Websites with personalized copy that adapts to the visitor, lead capture forms that AI-qualify in real time, and on-page chat that actually knows your business (not a generic GPT). Connected to your CRM, analytics, and whatever else your funnel needs.
Who we work with
- Small and mid-market businesses that want to do the work of a larger team without hiring the larger team.
- Ecommerce brands looking for personalization, customer service automation, and smarter email/SMS flows.
- B2B service businesses that want AI-powered lead research, outreach, and sales support.
- Marketing teams that want content, reporting, and campaign work to stop eating all their time.
- Agencies and consultants building AI-powered service offerings for their own clients.
How a typical AI build works
Week 1: Discovery and scoping
We talk with you and your team, understand the workflow we are automating or enhancing, and scope a realistic v1. You get a fixed-fee quote and a clear timeline. No open-ended discovery.
Weeks 2-4: Build
We build the system, connect it to your data and tools, test it on a narrow slice of work, and iterate based on your feedback. Most v1 builds land in 2-4 weeks.
Week 4+: Deploy and measure
We roll the system out to your team, measure actual hours saved or revenue lift, and plan the next iteration. Ongoing maintenance is optional, we can teach your team to own it, or manage it for you.
Why Good At Marketing for AI development?
- We are a marketing agency that actually builds. Most marketing agencies do not write code. Most AI developers do not understand marketing. We do both, which means the AI we build is actually useful for growth work.
- We ship real v1s in 2-4 weeks. Not quarter-long enterprise projects. You see working software fast.
- Fixed scope, fixed fee on v1. No billable-hour surprises. Ongoing retainers for maintenance or expansion are month-to-month.
- We use the tools you already have. HubSpot, Salesforce, Airtable, Notion, Slack, Gmail, Shopify, whatever your stack is, we build around it.
Frequently asked questions
How much does custom AI development cost?
Most v1 builds land between $5,000 and $25,000 in one-time scope, depending on integration complexity and custom UI requirements. Simple agent or automation builds can be less. Ongoing maintenance and expansion is typically $1,500-$5,000/month. We quote fixed-fee up front so you know exactly what you are paying.
What AI models do you use?
Whichever fits the job. Claude for most reasoning-heavy work, GPT-4/5 for general tasks and OpenAI-specific integrations, Gemini where it is the best fit. We are not married to a vendor, we pick based on what the task actually needs.
Can you build something that plugs into our existing software?
Yes, that is usually what we do. HubSpot, Salesforce, Airtable, Notion, Slack, Gmail, Google Workspace, Shopify, WordPress, we integrate with whatever you already use. If your tool has an API, we can plug into it.
How long does a typical AI build take?
Simple automations: 1-2 weeks. Custom agents with integrations: 2-4 weeks. Larger internal tools: 4-8 weeks. We quote a specific timeline after discovery. No open-ended scope creep.
Is our data safe?
We build on enterprise-grade AI APIs (Anthropic, OpenAI, Google) with data controls configured so your content is not used to train models. For sensitive work we can run locally-hosted open-source models instead. We are happy to sign an NDA and a DPA before any discovery work starts.
Do you support the AI systems after you build them?
Yes, but it is optional. We can transition ownership to your team with documentation and training, or we can run monthly retainers for maintenance, optimization, and expansion. Month-to-month, as always.
