About UltraFlux Digital
An AI-native digital marketing agency founded in San Diego to help small and mid-size businesses compete in the age of AI search.
Built for the AI Era
Matthew Kill founded UltraFlux Digital after watching small businesses get left behind as AI changed how customers search, call, and buy. Most agencies were still selling 2019 SEO playbooks. He built UltraFlux to do what the big agencies weren't: combine AI Engine Optimization, Voice AI, and traditional digital marketing under one roof — at a price point that works for growing businesses.
The name "UltraFlux" reflects the pace of change in digital marketing. The strategies that worked in 2022 are already obsolete. We stay ahead of that curve — and we bring our clients with us.
We're based in San Diego and serve clients nationwide. Our team is small by design — every client gets direct access to the people doing the work, not a layer of account managers.
AI Is Changing How Customers Find You
When someone asks ChatGPT "who's the best HVAC company near me?" or Perplexity "what's a good digital marketing agency in San Diego?" — the answer doesn't come from a Google ranking. It comes from structured data, authority signals, and AI-readable content. We call this AI Engine Optimization (AEO), and it's the next frontier beyond traditional SEO. Most agencies aren't doing it yet. We've been doing it since day one.
Traditional SEO
Optimizes for Google's crawlers. Still important, but only covers one channel.
AI Engine Optimization
Optimizes for ChatGPT, Gemini, Perplexity, and Claude — the new search engines. This is where the next wave of customers is.
Voice AI + AEO Together
When your AI receptionist captures the call AND your AEO gets you recommended — you own both ends of the customer journey.
Our Core Values
AI-Native
We use Claude, GPT-4, and Perplexity APIs in our daily workflow. We don't just talk about AI — we build with it.
Outcome-Focused
Every engagement starts with a clear goal and ends with a measurable result. No vanity metrics, no black-box reporting.
Transparent
You get weekly reports in plain English. You'll always know what we're working on, what it cost, and what it returned.

Matthew Kill
Founder & CEO — UltraFlux Digital
Matthew founded UltraFlux Digital with a clear thesis: the businesses that win in the next decade will be the ones that get AI to recommend them, not just Google. He brings a hands-on, outcome-first approach to every client engagement — and he answers his own phone.
Based in San Diego, Matthew works directly with every UltraFlux client. There's no account manager layer, no junior team doing the work without oversight. When you hire UltraFlux, you get Matthew — and the team he's built around him.
