Founder & Lead Auditor · MarginFix
Cristian Bragau, Founder & Lead Auditor
Cristian founded MarginFix in September 2024 after 15+ years in marketing and finance, a former consultancy strategy lead. He is on every kickoff and every readout, and he signs off every report before it reaches the client.
Background
Why MarginFix exists, in his words.
Cristian spent years inside agencies and consultancies before MarginFix, and kept seeing the same thing: capable teams spending on channels, campaigns and tools without an objective, evidenced read on what drove growth and what quietly drained margin. Agencies would not audit their own work, consultancies cost too much and took too long, and a generic AI tool could not be held accountable for the answer.
He founded MarginFix on 7 September 2024 to give those businesses the audit he wished his clients had. The first audits were run by hand, with consulting frameworks and spreadsheets, and ten clients proved the model. Since 2025 AI analysis agents take the volume and seven senior human gates keep the judgment, so an audit lands in 5 to 7 working days for a fixed fee.
“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.”
What he signs
Two names on every report; the auditor of record on 17 of the 74 published cases.
Every MarginFix report carries two names. The senior auditor who ran the audit signs the findings, and Cristian reviews and signs off the report before the readout. On 17 of the 74 published case studies he is also the auditor of record: Manufacturing, the consumer side of Pharma (OTC, medtech, nutraceuticals and diagnostics) and the mid market, vertical and enterprise B2B SaaS cases.
