The Problem with AI Today:
Most companies either lean on AI too much or don’t use it enough — Keystone Agency built the bridge in between.
AI where it makes sense, humans where it matters, so your company grows revenue without adding chaos.
The Old Way
- Hiring several people for your marketing team and paying around $75k per hire — about $225k per year in combined W-2 payroll on average.
- Juggling multiple people/vendors just to keep marketing moving
- Outsourcing to agencies that aren’t built with AI at the core
- Using AI that doesn’t understand your business, products, or customers
The New Way
- A proprietary combined AI layer + in-house human marketing team for about $23k/year
- One AI + human team to run your marketing at roughly 20% of the cost
- AI-built systems with human-led strategy and execution
- One dashboard for content, leads, support, and workflows that constantly learns from your business in real-time.

Your Questions, Answered
This is what sets us apart from other AI or digital marketing agencies. We call ourselves a hybrid (human + AI) agency because it means you're not choosing between “just AI” or “just humans” — you get both, working together in one system.
- Not an AI-only agency: We don’t hand you generic AI output and call it marketing. AI without strategy, brand context, and accountability quickly becomes noise.
- Not a traditional human-only agency: Old-school agencies run on meetings, manual work, and slow turnaround. That costs more and moves more slowly than the market does now.
What we actually are: a marketing agency that's been run like a real, human-led agency for years — but we rebuilt the whole operation from the ground up around a proprietary system that uses AI for speed and efficiency, while humans lead the strategy, creativity, and decisions.
In plain English: AI handles the heavy lifting and automation; humans handle the thinking and the taste. That’s how you get better output, faster execution, and lower cost—without sacrificing quality.
We treat your data as if it actually matters, and significantly exceed industry standards.
Everything is protected with enterprise-grade security:
- AES-256 encryption at rest
- TLS 1.2+ encryption in transit
- Your data is never used to train AI models
We’re GDPR and CCPA compliant and backed by a 99.9% uptime SLA.
On top of that, we’ve implemented Zero Day Retention (ZDR) with our LLM partners (like ChatGPT and Gemini), which means your data isn’t cached or stored on their side—something most newer agencies don’t even bother to set up.
Roll all your AI tools into one platform and cut $400+ in monthly costs.
You also get access to multiple AI models, integrated knowledge bases, and automation workflows you simply don’t get with most standalone tools.
Most teams are live in under 30 minutes.
Plug in your knowledge base, pick your AI models, and start automating. Our onboarding wizard walks you through it step by step, no tech expertise required.
Yes. We’ve got a free plan that lets you try the core features with a limited pool of credits—no credit card needed to get started.
If you plan to still be relevant/competitive in 3–5 years, then yes.
AI isn’t a "nice to have" anymore; it’s the new standard. Teams using AI today are:
- Responding to leads faster
- Producing more work with fewer people
- Making decisions off real data instead of gut feelings
That creates a compounding head start. Every month you’re not using AI, your competitors are training their systems, tightening their workflows, and lowering their costs. That gap doesn’t close easily—it widens.
The hard truth:
- Businesses that adopt AI now will look “too efficient to compete with” in a few years.
- Businesses that wait will end up paying more just to catch up—or get replaced by those who didn’t.
So no, this isn’t just “nice to have.” It’s closer to: adopt it now on your terms, or have it forced on you later by market pressure and competitors who already did.
We’re not just “another AI agency” bolting prompts onto someone else’s software. We own and control the stack end to end.
1. Keystone gives you an AI “staff,” not just a chatbot.
Through Keystone Agency, you’re not buying a single bot—you’re building an AI department:
- AI agents that handle support, intake, and follow-ups
- Automation workflows that tie into your CRM, calendars, email, and internal tools
- Central management so your AI “employees” stay on-brand and on-script
Most “AI agencies” stop at a pretty front-end chat bubble; we wire AI into your operations so it actually moves revenue and removes manual work.
2. Real performance (on your website): dedicated, high-frequency infrastructure.
We’re not tossing your business on a noisy shared server (which is why we require everyone who joins us to use our hosting for their website). Our high-frequency hosting runs on dedicated Intel Xeon CPUs with NVMe SSDs—no throttling, no mystery neighbors killing your speed. We optimize Core Web Vitals and even guarantee 90+ PageSpeed scores, which most agencies can’t hit on their own sites, let alone yours.
3. AI visibility, not just old-school SEO.
Everyone talks about SEO. We also focus on AI discovery—getting your brand mentioned inside tools like ChatGPT and Gemini using our AI Search Visibility Engine (AI Optimization). While most agencies are still stuck on search rankings only, we’re already engineering for how people actually find businesses through AI assistants.
4. Local, accountable, and hands-on.
We’re based in York, PA. If you want to sit down over coffee and review strategy or performance, you can. We don’t disappear after launch—we monitor, tweak, and keep tuning your site and AI agents as your business changes.
In short: other agencies rent tools; we built the tools, the hosting, and the AI layer—and then we stay in the loop as your technical and AI partner. That’s why our clients are blowing past their competitors.
