Most marketing fails because the pieces don't talk to each other.
Your ads bring in clicks that your content doesn’t convert. Your content earns trust your follow-up never capitalises on. Your CRM sits half-empty because nothing automatically feeds it. Each channel does its own thing. The gaps between them are where your revenue leaks.
The businesses scaling fastest in 2026 are not running more marketing. They are running fewer pieces, better connected.
The Growth Elixir AI is what that connected system looks like.
What Is The Growth Elixir AI™?
The complete revenue system, run by one senior strategist.
The Growth Elixir AI combines four things most businesses currently buy from four different vendors: paid advertising across Meta, YouTube, and Connected TV. AI-powered content that compounds visibility across Google, ChatGPT, Perplexity, and Gemini. Automated follow-up across email and WhatsApp. And a single Looker dashboard pulling spend, leads, content, and bookings into one source of truth.
Designed, built, and managed by Katrina M McBride. Over a decade of Meta advertising experience. One senior strategist. No junior account managers. No agency layers.
TWO PATHS
Pick the one that fits.
The Lead Engine
For service businesses that need a consistent, predictable flow of qualified leads.
Built For:
Law firms and legal practices. Medical clinics and healthcare providers. Coaches, consultants, and professional services. Local service businesses in any sector where the primary goal is generating qualified enquiries and booking consultations.
The Problem This Solves:
- You are getting website traffic but very few enquiries
- Your leads are inconsistent, some months good, some months nothing
- When leads do come in they are often unqualified and waste your team’s time
- You follow up with enquiries but too slowly and they go cold
- You have no clear picture of what your marketing is actually returning
The Revenue Engine
For ecommerce and product brands that want consistent sales, stronger ROAS, and a customer base that keeps coming back.
Built For:
Skincare and beauty brands. Hair product companies. Food and drink brands. Lifestyle and wellness products. Any ecommerce business selling direct to consumer that wants to scale revenue predictably without constantly increasing ad spend.
The Problem This Solves:
- Your ad spend keeps going up but ROAS stays flat or declines
- You are acquiring new customers but they are not coming back to buy again
- Your creative fatigues quickly and you are constantly scrambling for new content
- You have no system for turning one-time buyers into loyal repeat customers
- You are selling in Ireland and the UK but cannot break into international markets

FAQs
What is The Growth Elixir AI™ System?
Growth Elixir AI™ is a subscription-based growth system for service businesses.
We combine AI-powered strategy, high-performing video scripts, and paid social ad tools to help local brands grow their presence and get booked every single month — with or without a marketing team.
How is Growth Elixir AI™ different from a “regular” marketing agency?
Most agencies treat content, ads, and tracking as separate tasks. We combine authentic human-produced content with AI-driven repurposing and real-time optimization—so you get one cohesive system rather than disconnected pieces. In plain terms, we don’t just post and pray: we use AI to spot your best content immediately, push ad spend behind it, and keep you visible—month after month.
I don’t have much time. How much work do I need to do each month?
That depends on which package you choose. With our Done-For-You option, you show up for one video shoot and a 30-minute strategy call. From there, we handle everything else—repurposing, posting, ads, lead-qualifying, and reporting. If you pick Done-With-You, you’ll spend about 1–2 hours reviewing AI-generated scripts and approving content. Either way, you’ll never spend more than a couple hours per month on marketing—we run the rest.
I’ve seen other “AI” offers that overpromise. How do I know this is real?
We firmly believe in “AI + Human + Process.” Our team writes your core videos and messaging first. Then, AI helps us repurpose, optimize, and track performance, so you benefit from speed without sacrificing quality. Every script, caption, and ad is reviewed by a real person who knows your brand. If AI ever suggests something off-brand, we override it. The result is a system that scales proven human creativity with AI efficiency—no empty hype.
What if I don’t see any new bookings after 30 days?
We stand behind our process with a no-brainer guarantee: if you follow our system (filming on schedule, reviewing ads, approving AI-generated assets) and don’t see measurable improvement in leads/bookings within 30 days, we’ll keep working with you for free until you do.
How do I know this will work in my industry or market?
Because we’ve tested and refined this system across dozens of service-based businesses, including clinics, coaches, local trades, consultants, and more. Growth Elixir AI™ is built around “authentic content + AI optimization + ad architecture + real-time dashboards,” which applies to virtually any business selling expertise or services. If your offerings rely on trust and visibility, this system helps you show up where and when your ideal clients are looking.
Is it worth the cost? My budget is tight.
At €2,500 per month, you’re getting a turnkey growth engine that replaces a full-time content/ads team. That’s less than hiring a junior marketer (€3–4k/month) — but you get a full expert team + guaranteed results.
On average, clients see a 3–5× return on ad spend within 90 days. Put another way, every €1,000 you invest typically drives €3,000–€5,000 back in booked appointments. If the math doesn’t work for you, we’ll tell you upfront—no hard sell. But most SMBs find that the time saved and leads gained make Growth Elixir AI™ not just affordable, but one of the best investments they can make.
