👻 Ghostwriters Busted

This past week, I’ve been running hard on two tracks—Letter Operators and AgentStacker—and they’re starting to overlap in ways I didn’t expect.

Both started as services. Both now feel like infrastructure.

With Letter Operators, we now manage over 200K emails a week running 14 newsletters. Our customers keep control of their beehiiv, grow through ad revenue, and get content that sounds like them—because it’s pulled from their real-world digital footprint and shaped by custom AI workflows.

We’re not trying to be another ghostwriting service. We’re trying to kill ghostwriting altogether.

This is content that’s remembered, not just generated.

At the same time, AgentStacker has taken off from its origins building an onboarding agent for a WordPress agency. What started as tailored AI experiences that walk new clients through onboarding, sync with internal ops, and generate reports has now evolved into a streamlined productized menu.

Both businesses now orbit the same principle: Replace clunky SaaS and human bottlenecks with lean agentic workflows that own delivery.

Here’s how that’s starting to look…

🧠 Letter Operators: the creative OS play

We’re continuing to build a backend that turns our DFY service into a software-enabled system. Think Notion x beehiiv x Make—but without the mess. The AI stack connects:

And because the customer owns their beehiiv account, they can run their own boosts, tap into the ad network, and even resell space. This would not be possible if we’d chosen to go onto a beehiiv enterprise plan and put every customer in our account.

And we’re now testing a customer dashboard that shows upcoming drafts, approvals, ad inventory, and revenue—completely async.

⚙️ AgentStacker: Onboarding Agents & Client OS

I’ve now productized AgentStacker into two standalone offers, making it easier for us to both sell and deliver.

It started with custom builds: onboarding agents, dashboards, internal routing flows. But the more we delivered, the more we saw patterns. Same problems, same hacks, same bloated SaaS tools duct-taped together with Zapier and VA labor.

So we packaged the whole thing into a productized menu.

For $5K, Lead OS turns your intake flow into an AI-powered onboarding experience—built to qualify leads, sync with your stack, and actually do something useful with form submissions.

And for agencies outgrowing SPP, we now offer Client OS: a fully branded, ownable client portal with integrated payments, messaging, task tracking, and AI workflows behind the scenes. One-off build, no ongoing SaaS fees, no endless human friction. That’s $15K delivered in about a month.

Most teams are paying $300 to $500 a month for SPP, then layering in manual work anyway. We’re giving them an AI-native alternative that replaces both the software and the staffing.

Next up is starting outbound email to marketing agencies as unlike LetterOperators, we’re not getting that many inbound leads now.
