Enterprise marketing clarity, built for the rest of us.
Big companies have always had teams of analysts and six figure consultants to tell them exactly where their marketing is working, and where it’s bleeding money. Everyone else has been flying blind. MarginFix exists to change that.
This is a published record, not a claim: 74 audits, $4.5M+ in margin identified.
MarginFix (marginfix.ai) is an independent marketing and margin audit company for small and midsize businesses. It is not the LaTeX package marginfix and is not affiliated with marginfix.com.
Most marketing budgets are spent without a clear view of what’s actually working.
We started MarginFix because we kept seeing the same thing: capable teams pouring money into channels, campaigns and tools without an objective, evidenced read on what was driving growth and what was quietly draining margin. Agencies won’t audit their own work. Consultancies cost too much and take too long. And a generic AI tool can’t be held accountable for the answer.
So we built a different model, one that combines the speed and scale of AI with the judgment and accountability of senior human auditors. The result is enterprise grade marketing analysis, delivered in days, at a fraction of the traditional cost.
“I spent years inside agencies and consultancies watching good businesses overspend because no one would give them a straight, objective answer. MarginFix is the tool I wished those clients had: the rigor of a top tier audit, without the six figure invoice or the three month wait.”
Who checks the people spending your marketing budget?
Cristian, founder of MarginFix, on the gap between what agencies report and what a business keeps, and how an independent audit closes it.

Machines for scale. Humans for judgment.
37 specialized AI agents run consulting grade frameworks across your entire funnel, spend and economics, processing in hours what would take an analyst weeks.
A senior auditor reviews and signs off every stage before it advances. The AI does the volume; a human owns the judgment and stands behind the recommendation.
Ours is days, at a tenth of the cost.
Same frameworks. Same seniority signing off. A fundamentally faster, more affordable way to get the answer.
Ours is published: $1,450 to $5,950 across three fixed tiers. See what each tier includes →Built audit by audit.
MarginFix LLC is a Delaware limited liability company, formed on October 26, 2026 (file number 10817253), owned by Cristian Bragau, and the company our US clients contract with. The practice behind it is older. MarginFix began as Cristian Bragau's own audit practice, Cristian Daniel Bragau PFA, registered in Romania as a sole trader in December 2022. Every audit in our library, all 74 published audits, was contracted through that practice between 2024 and 2026, with Cristian leading some himself and independent senior auditors running the rest under his review. In June 2026 the practice became a company, MARGIN FIX AI S.R.L., which contracts with our clients outside the US. The New York address is a mailbox, not an office. The team works from the United States and Europe.
Cristian Bragau registers his practice as a Romanian sole trader, Cristian Daniel Bragau PFA. From 2024 it audits marketing spend against margin, by hand at first: consulting frameworks, spreadsheets, late nights. Every client contracts with his practice.
37 specialized agents take the volume; seven senior human gates keep the judgment. 5 to 7 working day delivery becomes standard.
The practice becomes a company, MARGIN FIX AI S.R.L., and marginfix.ai launches. The library follows in July: 74 audits, every one contracted through the practice between 2024 and 2026, anonymized and published.
Cristian Bragau forms MarginFix LLC in Delaware (file number 10817253); from today our US clients contract with it. $4.5M+ identified and counting, and the findings guarantee has grown with it, to $10,000–$50,000 by tier.
Four principles behind every audit.
We don’t run your ads, so we’ve no waste to defend. The only incentive is the truth.
Every finding is backed by your data and benchmarked against comparable audits.
Plain English recommendations a founder can act on Monday morning.
We tie our work to your margin and back it with a money back guarantee.
Senior operators, not junior analysts.
Every audit is run and reviewed by experienced marketing and finance operators. Here is the team: four independent senior auditors, a marketing analyst and business development, with their profiles.
Viewer and analyst roles on the accounts in scope. We never hold admin rights, and we never change a setting, a budget or a campaign.
Access is revoked at your readout. Working data is deleted within 30 days. It is never used to train AI models.

“Short version, we were about to cut the wrong thing. Glad we got this done first.”

Contribution margin on the two top campaigns: −7% → +9%
“Revenue grew and cash didn't. Victoria rebuilt margin per order after shipping, returns and payment fees, and our two biggest prospecting campaigns were losing money on every sale. We stopped scaling them.”
Victoria MillerLead auditor on this audit“Founder was on the kickoff call, the auditor who did the work ran the readout. Small thing but I've never had that with a consultancy before. You actually talk to the people who know the answers.”
$118k a year of wasted spend cut in 7 days
Rebates paid on volume never actually earned: 19% → 1%
“Rebate expense outran distributor volume and we could not see why. Cristian reconciled rebates paid against volume actually shipped and paid for, tier by tier: accruals had run off gross purchase orders. Quarterly true ups now catch it.”
Cristian BragauSenior Auditor · signed this audit off“The thing that won me over was a line in the report that basically said "we can't prove this one, so we're not counting it". Nobody does that. Made me trust everything else in there.”
$96k a year of wasted spend cut in 7 days
App installs that funded a real account: 24% → 63%
“Installs looked great and funded accounts stagnated. David followed sign ups through to funding, and the bonus was buying registrations from people who claimed it and never transacted. Incentives now pay on activation, not the download.”
David JacksonSenior Auditor · signed this audit off“I've paid for a few of these "audits" over the years and they usually end with a pitch. This one ended with a list of what to fix and which parts we could do ourselves. Some of it was not what I wanted to hear. All of it was right.”

Enterprise deal margin lost to quarter end: 5 pts lost → 0 pts lost
“Bookings hit target while margin slipped. Cristian split our discounting by timing and rep: concessions spiked in the last days of every quarter because buyers had learned to wait. Approval thresholds fixed it without losing deals.”
Cristian BragauSenior Auditor · signed this audit off“Solid work. Lost a star only because the first week dragged, mostly getting them access on our end so partly our fault. After that it moved fast and the readout was really clear.”

Paid social proven to lift store visits: ~1 in 3 → 9 in 10
“Our CFO doubted that online ads drove store visits. David's matched market geo lift test proved the doubt right: footfall barely changed where the ads were off. The budget moved to markets and channels that passed the test.”

Congress spend with a tracked return: 8% → 88%
“Six figures a year in congresses and KOL sponsorships, renewed on habit. Leslie tried to connect it to share of voice, engagement or prescribing and found no instrumentation at all. The unmeasurable part now funds engagement we can track.”

Courier bonuses paid into already full zones: 22% → 3%
“Incentive spend rose while service levels stayed flat. Alex matched bonus payouts against real time courier availability by zone: in dense areas we paid couriers who would have worked anyway. Bonuses now fire only where coverage is short.”

Active users actually being billed: 93% → 99%
“Expansion lagged what we saw inside accounts. Victoria reconciled active users against billed seats: many customers used more seats than they paid for. Automated true ups now capture it, and nobody pushed back.”

Qualified inbound calls that became bookings: 2 in 3 → 9 in 10
“Marketing hit every target and revenue stalled. Leslie followed our qualified calls into intake and about a third were dropped at busy times or never followed up. Fixing staffing and call handling converted demand we had already paid for.”
Leslie MartinSenior Auditor · signed this audit off“The audit paid for itself in three weeks. It found margin we didn’t know we were losing, and told us exactly what to fix first.”
$10,000 to $50,000 of findings, or your money back.
