We create the marketing logic. Then we build the AI stack that runs it.
Hack Tech Stack is a senior marketing team. We design your brand's marketing logic: how it sounds, who it's for, what it says to each of them, and how it goes to market. Then we build the AI stack that executes it at volume. Run it with us, or take the keys. Everything we build is yours to keep.
The agents aren't the moat. The fit is.
Here's the open secret of AI marketing in 2026: the tooling is a commodity. Your competitor can stand up the same agents you can, from the same five vendors, in the same afternoon. So if everyone owns the machine, the only thing left to compete on is what you point it at: the right message, the right scope, the right channels, and the right tools for yourbusiness specifically. That's not a setup task. That's the whole job, and it's what we sell: the marketing logic, and the stack built to run it.
The way we do it is the part most vendors skip: senior marketing judgement decides what's worth making, and a small set of agents, trained on your voice manual and yours to keep, makes it at volume. The expertise is the brain. The agents are the hands. Everyone else sells you one or the other. We don't separate them, and when we hand off, the agents stay in your stack.
The model is a competent ghostwriter. It's a terrible brand strategist.
Every stack we've audited starts the same way: a Notion doc of generic “best practices” feeding an LLM that produces work the team is quietly embarrassed to publish. We start at the opposite end: your voice, distilled, encoded, made operable. And when we say “voice,” we mean more than how you write. The voice manual is the brand's operating system: how you sound, how you look, who you're for, what you say to each of them, and how you go to market. Every layer of the stack runs against that one document. Nothing else works without it. Tools come and go; the voice manual is the asset that outlives all of them.
Six layers. Pick four.
We don't sell a six-layer cake. We propose a stack scoped to your category, your team, and the work you've already done, usually three or four layers, built and handed off in phases. Each layer is a concrete deliverable: a system we build, document, and hand off working. The others stay on the menu until you actually need them. Below: the full menu.

One thing we've learned watching this space: the tools move fast. This year's favorite often looks different by next year, and the category is consolidating quickly. That's good news if you're built for it. So we make the stack portable: the voice manual, the prompts, the schemas, and the measurement model all belong to you, not to a vendor's roadmap. When a better tool comes along, you swap the tool and keep the strategy.
A free audit. Then we decide together.
Three steps: a free audit, a fixed-price build scoped to the layers that matter for the next two quarters, and then we either hand off or stay on as your fractional marketing team. No annual lock-in, no platform you have to marry.
Audit
A free 45-minute call plus a written assessment of what's working, what's leaking, and which two things to fix first. Yours to keep, whether or not we work together.
Stack design
If there's a fit, we propose a stack scoped to your voice, your team, and your category. Modular: pick the layers you need, defer the rest. Fixed-price by phase.
Operate
We build, train, hand off, or stay on as the fractional team running it. Monthly written reviews; quarterly recalibration with your in-house leadership.
Brand-level results, not vanity metrics.
We can hit the tactical numbers: tens of thousands of emails at a 70%+ open rate and 12% clicks. We're glad to. But that's the old scoreboard. The work we're proudest of is the kind that changes what a company is worth. One digital rebrand we led helped carry a business to an $850M sale. That's the result we keep our eyes on, and the kind we build your stack to produce.
What clients actually say.
— Four of fourteenThey didn't try to sound like us. They figured out how we actually sound, then built a system that produces work my team mistakes for their own writing. The brand finally matches the company we became.
Our buyers knew the category but they didn't know us. A quarter in, the right people were starting conversations already warm. Authority in our space turned out to be worth more than another paid channel.
First outside engagement in years that didn't end with us quietly rewriting everything. The deliverables ship, in our voice, on time, and the agents stayed with us when the work was done.
One call. A real read on what your stack is missing.
Send us a few details and we'll come back within a week with a written assessment that looks across the whole brand system: voice, design, audience, messaging, and go-to-market. What's working, what's leaking, which tools to keep, which to cancel, and the two things to fix before you spend another dollar. No pitch deck. No “growth call.” If there's a fit, we talk about an engagement.
