I guarantee increasing your conversions by 30% in 90 days.
More leads. Lower waste. Campaigns that convert, not just click. I run the AI systems that catch problems fast and test winners faster, then make every call myself, across Meta Ads, Google Ads, TikTok Ads, ChatGPT Ads, landing pages, CRO, and growth strategy.
AI does the digging, I make the calls.
Facebook & Instagram campaigns
AI scans your creative and audience data daily, so fatigue and overlap get caught before they cost you money. I still check every account myself, every day.
Google AdsSearch & Performance Max
AI flags wasted search terms and bid problems as they happen, not weeks later in a report. I decide what's worth acting on and what isn't.
TikTok AdsShort-form creative that stops the scroll
AI tracks watch-through and engagement patterns to catch a winning hook early, so budget moves toward what's actually holding attention.
ChatGPT AdsPlacements inside ChatGPT conversations
A newer channel most agencies haven't touched yet. I set up and manage these placements directly, testing what earns a click inside a chat, not a feed.
Landing Pages & CROPages built to convert
AI helps me build and prioritize more test variants in less time. I pick what's worth using, so more of your traffic turns into a lead or a sale.
Growth StrategyWhere to put your time and budget next
I use AI to pull patterns out of your account data across every channel, then build the plan for what to fix first and what to leave alone.
You work with me. Not a rotating team of account managers.
I'm not in the AI business. I'm in the paid media business, and AI is how I do it better.
I'm Barrie Le Gall, an AI consultant for paid media and growth, based in Northampton, UK. I've been running paid campaigns since 2010, over 15 years, and I still work every account myself: no handing you off to a junior once the contract's signed. I build and run the AI systems behind the work myself: scanning your account data, spotting patterns, and flagging problems faster than I could catch alone. Every recommendation that comes out of them is checked and made by me before it touches your account.
Built for businesses already spending on ads.
Running Meta, TikTok, and Google ads
Brands with paid social and search spend that's grown past the point where gut feel gets you anywhere. I find where the budget is leaking, then fix how the account is structured, not just the settings inside it.
Running paid search and lead-gen ads
Businesses with real ad budget and a sales team that needs leads. I tighten the path from click to booked call: tracking, targeting, follow-up. Spend should turn into pipeline, not just clicks.
Three ways to work together. Start with the diagnostic.
The Diagnostic
A free audit of your Meta, Google, TikTok, and ChatGPT accounts, plus your tracking setup. I show you where spend is wasted, what's mis-tracked, and what's underpriced. You get a prioritized list of what to fix first, not a slide deck of observations, and no cost to find out.
Managed Execution
I run the fixes from the diagnostic: campaign restructuring, budget reallocation, creative refresh, landing page changes, and ongoing optimization across Meta, Google, TikTok, and ChatGPT.
Embedded Advisor
For businesses with an in-house marketing team. I act as the second opinion your team checks its thinking against: reviewing plans, unblocking platform-specific problems, and showing them what's worth automating and what still needs a human call.
30% more conversions in 90 days, or I keep working until you get there.
What you get
Starting from your Diagnostic, I manage and optimize your Meta and Google accounts for 90 days. If your conversions haven't grown by 30% against your baseline by day 90, I keep working on your account at no extra cost until they have.
What it requires
- You're already running ads on Meta or Google, and they're running profitably. This isn't for brand-new accounts starting from zero: I need an existing baseline to beat.
- You give me creative and campaign control. I'll check ad copy and claims with you for accuracy, but the strategy, targeting, and creative decisions are mine to make. If I didn't build it, I can't guarantee it.
- Your business isn't selling anything shady, illegal, or involved in multi-level marketing.
Baseline is set from your last 90 days of performance before we start. I only take on a limited number of new clients under this guarantee each month, so there's sometimes a short wait to start. Eligibility is confirmed during the Diagnostic.

Common questions, answered plainly.
What does FoundUB4 do?
FoundUB4 is an AI consultancy for paid media and growth, run by Barrie Le Gall, an AI consultant. Services cover Meta Ads, Google Ads, TikTok Ads, ChatGPT Ads, landing pages and CRO, and growth strategy. Barrie builds the AI systems that do the digging; the judgment on what to fix and how comes from him.
Who is FoundUB4 for?
Ecommerce and DTC brands running Meta, TikTok, and Google ads, and service businesses running paid search and lead-gen ads. Both need existing ad spend and a working baseline to build from, not a first campaign from scratch.
Which ad platforms do you manage?
Meta Ads, Google Ads, TikTok Ads, and ChatGPT Ads, alongside landing pages, CRO, and growth strategy. I don't currently manage LinkedIn or Amazon Ads.
What's included in the Diagnostic?
A free cross-channel audit of your Meta, Google, TikTok, and ChatGPT accounts and your tracking setup. You get a prioritized list of what's wasted, what's mis-tracked, what's underpriced, and what to fix first, not a slide deck of general observations. There's no charge for the call or the diagnostic itself.
How does the 30% conversion guarantee work?
Starting from your Diagnostic, Barrie manages and optimizes your Meta and Google accounts for 90 days. If conversions haven't grown by 30% against your baseline by day 90, he keeps working on the account at no extra cost until they have. It requires an existing, profitable ad account, creative control, and a business that isn't selling anything shady, illegal, or involved in multi-level marketing.
How is AI actually used in the work?
Barrie builds and runs the AI systems himself: scanning creative and audience data, flagging wasted search terms and bid issues, generating and prioritizing landing page test variants, and surfacing patterns across accounts. Every recommendation and every fix is still reviewed and made by Barrie personally, not automated end to end.
Will I work with Barrie directly, or a team of account managers?
Directly with Barrie. Accounts aren't handed off to a junior after the contract is signed.
How do I get started?
Book a diagnostic through the contact form on this page, or email Barrie directly. The call and the initial diagnostic are free, so you get a straight answer before you commit to anything ongoing.
