AI automation,
done for you.
We connect the tools you already use, automate the busywork, and build the websites and voice agents on top. We did the experimenting — you get what already works.

What we do
Beautiful on the surface.
Powerful underneath.
AI automation, API and systems integration, websites and voice agents — designed, built and looked after by one studio.
Connect the tools you already pay for — forms, email, phone and text, booking pages, payments and your lead inbox — so leads, bookings and follow-ups move on their own. You approve the rules; we build, test and document it, and can keep it running for you.

Using something else, like a CRM or booking platform? If it has an API, we can usually connect it — we confirm it during scoping, before you pay for a build.
Most of what we build for clients, we run on our own brands too.

FAQ
Straight answers.
What does Ghost AI Systems do?
We’re an AI automation and development studio. We connect the tools a business already uses, automate the repetitive work between them — follow-up, routing, reminders, content — and build the websites, apps and AI voice agents that sit on top. You work directly with founder Daniel Castillo.
Which tools can you connect?
On live projects we’ve connected Stripe and Square payments, Twilio phone lines, Meta’s page and conversion APIs, Google Analytics, transactional email and Postgres databases. If a tool has an API or a supported integration, we can usually connect it — we confirm it during scoping, before you pay for a build.
Do I have to manage it after launch?
Only if you want to. We can host and maintain it on a monthly plan scoped to your project, or hand it off with documentation so your team owns it.
What does it cost?
Landing page with intake form: $1,000 plus $200/month for hosting and maintenance. Full website (multi-page, local SEO, booking and integrations): from $2,500 and quoted in writing to your scope. Growth Stack content automation: $8,500 with a two-week rollout. AI voice agents: from $497/month plus a $497 one-time setup. Custom automation, integrations, apps and consulting are quoted in writing after a short brief.
How fast can you launch?
Landing pages: we aim to send your first draft within two business days of receiving your brief and content. Full websites: timing is confirmed in your written scope. Growth Stack rolls out over two weeks. Automation and app timelines are set in your written scope.
Do I need to be in Orlando?
No. We’re based in Orlando, Florida, and work remotely with businesses across the U.S.
Will the AI pretend to be a person?
No. Ghost tells you it’s an AI assistant, and the agents we build are set up never to claim to be human. When a conversation needs a person, it can be passed to your team with a summary.
We’re not sure where AI fits. Can you help?
Yes. We start with a review of your tools and where time and leads are lost, then recommend the smallest useful first build. If AI isn’t the right fix, we’ll say so.
