Senior marketing thinking. Real work getting done.
Most businesses do not need another marketing deck. They need experienced operators who can find the gap, build the plan, and execute the work across brand, awareness, acquisition, conversion, and retention.
You are not hiring a strategy consultant who disappears after the roadmap. You are not getting a junior account team. You are working with people who have led growth and know how to ship.
Your marketing is busy. That does not mean it is working.
Business owners usually come to us when they are investing time, money, and energy into marketing but still do not have a clear system for growth.
Great plan. Who’s doing it?
That question is where most marketing engagements fall apart.
A consultant can give you a roadmap. An agency can sell you a list of tactics. A freelancer can complete isolated tasks. But growing businesses need strategy and execution connected by people who understand the whole business.
Big Brain Strategy closes that gap. We help identify what needs to happen, prioritize the work that matters, and execute across the right growth lanes.
Experienced operators, not a handoff team.
Big Brain Strategy is led by marketers who have built growth systems inside real businesses, not just advised from the outside.
Mike Birt
Co-Founder and Lead Strategist
Mike helps businesses find the real growth problem.
Mike built his career solving growth problems for businesses that had hit a wall. His work is grounded in finding the real constraint, sharpening the brand, and turning strategy into execution.
As a partner and Chief Marketing Officer at Grunt Style, he helped transform a $6M veteran-owned apparel company into an $80M ecommerce brand. That growth came from understanding the customer, building systems, growing the owned audience, improving retention, and making the brand more than a product catalog.
More recently, Mike led the brand strategy behind Berry Law’s veteran voice engagement. Berry Law is a veteran-led national law firm that has appeared on the Inc. 5000 eight times. The work helped a veteran-founded firm sound like one again by replacing generic legal marketing with a content system built around the audience’s real world.
Nada Djuric
Co-Founder and Growth Operator
Nada turns strategy into work that actually ships.
Nada brings the operational side of marketing growth into focus. She helps turn strategy into campaigns, content, email, customer communication, and repeatable execution systems.
Her background spans ecommerce, lifecycle marketing, retention, campaign planning, customer communication, and execution management. She helps make sure the work does not stay in a planning document. It gets built, launched, improved, and kept moving.
For clients, that means strategy has a path into real deliverables. The brand voice becomes content. The customer journey becomes email and SMS. The campaign plan becomes work in market. The monthly priorities become visible progress.
Brand work only matters when it moves something real.
The Berry Law engagement shows the kind of work Big Brain Strategy is built for: finding the authentic advantage, turning it into content people care about, then measuring the signals that show the brand is getting stronger.
Berry Law
Brand VoiceBerry Law is a veteran-founded, veteran-focused firm. The problem was not legal expertise. The problem was that the brand voice had drifted into generic legal marketing while competitors were moving toward AI-generated sameness.
We built a two-track content system: story-driven veteran voice content that earned attention before a legal need existed, and legal content reformatted into useful social-first education veterans could save and share.
Why this belongs on the About page
Recent ProofThis case study supports the clearest version of Mike’s expertise: he does not just talk about brand. He builds brand systems that create business signals.
It also shows the bridge between your positioning and your offer. The work included strategy, content series, infographics, editing standards, interview guides, reporting, and handoff tools that allowed the client to keep using the voice after the engagement.
Plain English version: Big Brain Strategy found the brand advantage, turned it into work, proved it in market, and left the client with a system they could keep running.
We connect the brand, the strategy, and the work.
You do not win by buying random tactics. You win by making the business easier to understand, easier to trust, and easier to choose, then executing the right channels in the right order.
Find the breakdown
We look at the brand, message, customer journey, website, content, paid media, email, retention, and reporting to see where the system is leaking.
Prioritize the growth lanes
We decide which parts of the system need attention first, whether that is awareness, acquisition, conversion, retention, or the brand foundation underneath it all.
Build the plan and ship the work
We turn strategy into content, campaigns, email, SMS, landing page recommendations, paid media direction, video, and customer communication.
Measure what should actually move
We care about signals that matter: leads, sales, search behavior, retention, repeat purchase, branded demand, conversion, and revenue movement.
Strategy is the baseline. Execution is the difference.
Every engagement starts with the thinking. The level of support depends on how much of the growth system you want us to help execute.
