Agency of One: I Built a Solo Cold Outreach Stack in One Chat
A solo agency owner shouldn't need five tools and a VA to run cold outreach. Here's what 3 minutes in one chat with an AI agent looks like — full pipeline, never auto-sent.
The pitch
A solo agency owner running cold outreach shouldn't need five tools and a VA.
I gave my AI agent one spec: find every south-facing roof in Phoenix with no solar panels yet, enrich the installer with Apollo, draft a personalized cold email per rooftop, and wire the whole thing into a live CRM dashboard. One chat. Three minutes. Nine prospects fully reviewed, ready to send.
Watch the demo (3 min)
The stack you'll see
SureThing — the AI SDR (surething.io)
OpenStreetMap — south-facing roof polygons
Google Maps Static API — satellite tiles (the legit way, no scraping)
Claude vision — panels / no panels detection
Apollo — people search + data enrichment
A CRM dashboard agent — built on the fly during the demo
The five beats that matter
0:42 Vision over satellite tiles. Apollo has the company. It doesn't have the roof. Claude vision marks each tile — panels detected, no panels, or partially shaded.
1:05 Edit-mid-flight. I rewrote the subject. I tightened a sentence. The agent doesn't ship until I sign off. Domain stays clean.
1:30 The agent learns my signoff. I added "Cofounder of SureThing" to my own signature once. It propagated to every future draft. No template — just pattern recognition from my own edits.
2:00 Self-learning heuristic. SureThing noticed I rejected two generic openers and updated its own drafting heuristic mid-run. It's not just executing — it's rewriting its own playbook.
2:20 Two agents, one AppDB. The CRM Dashboard agent boots up empty, @-mentions the Visual Leads Gen agent right inside the chat, asks for the outreach state. They sync through the project's AppDB. No human in the middle. This is the part that doesn't exist in Zapier.
The Agency of One stack
You used to need HighLevel for the CRM, Zapier for the wiring, Apollo for contacts, a VA to draft, and a contractor to build the dashboard. Replace all of it with one chat to a SureThing agent.
Whatever vertical you serve — swap "solar installer" for dentists, restaurants, real estate, ML engineering recruiters, your call — same play.
