“Every pixel, every word, every second of an ad needs to justify its existence through performance data.”

Vivien Lacroix, 32, is a freelance performance marketer specializing in ad creative optimization, operating primarily between Paris and Brussels. Armed with a Master's degree in business, he carved out his niche seven years ago, leveraging his analytical prowess to help app startups and direct-to-consumer (DTC) brands achieve better ad performance. His income hovers around €84k annually, a figure he meticulously manages, prioritizing reinvestment in his business and long-term financial security over immediate gratification. Vivien's current operational framework is a testament to his resourcefulness: a patchwork of paid and free digital tools, meticulously integrated and supplemented by a shared spreadsheet that serves as his central nervous system for tracking creative variants, language adaptations, and performance metrics. He lives alone in a functional, minimalist apartment in Paris's 11th arrondissement, a space that mirrors his professional ethos – efficient and uncluttered. His daily routine is disciplined, often starting with a review of industry trends and campaign data, followed by intensive creative production and analysis. He recently decided to invest in a more robust video editing software subscription, a move driven by the need for greater precision in his split-screen demo creations and a desire to reduce manual post-production work. This decision reflects his core values: iteration, evidence, and precision. He views time as a critical, non-renewable resource, constantly seeking ways to streamline his workflow and maximize output. While he enjoys the autonomy of freelancing, he is acutely aware of the pressures of client acquisition and the need for continuous skill development in the ever-evolving digital marketing landscape. His approach to money is pragmatic; he saves diligently, viewing it as a tool for future freedom and stability, rather than an end in itself. He recently declined a project with a lower budget but higher creative freedom, opting instead for a more data-intensive campaign for a promising e-commerce client, a choice that underscores his commitment to evidence-based marketing and measurable results.

Background & daily life

A day in their life

Vivien's typical weekday begins around 7:30 AM with a strong espresso and a quick scan of startup news and industry blogs. By 8:30 AM, he's at his desk, reviewing performance metrics from ongoing campaigns and responding to client emails. His mornings are dedicated to creative production – editing video clips, writing ad copy variations, and generating subtitles using his current tool stack. After a simple lunch, he dedicates the afternoon to deeper analysis, identifying trends, and planning new A/B tests. He often has a client call scheduled for late afternoon. He aims to wrap up by 7 PM, often going for a bike ride or preparing dinner, before a brief evening session reviewing analytics or learning about new marketing techniques.

Lifestyle

Vivien lives a focused, work-centric life in Paris, prioritizing professional growth and financial stability. His apartment is minimalist and functional, reflecting his no-nonsense approach. He enjoys cycling through the city for exercise and mental clarity, often listening to podcasts. Socially, he prefers smaller gatherings with close friends over large parties, valuing deep conversations. His spending is deliberate, with a strong emphasis on investing in tools that enhance his productivity and saving for future financial security, rather than on immediate luxuries. He cooks most of his meals to save money and maintain a healthy diet.

Work life

Vivien's days are a constant juggle of client communication, creative production, and performance analysis. He spends significant time in his home office, meticulously crafting ad variants. His workflow involves stitching together various software – a video editor, a transcription service, a subtitle generator, and analytics platforms – often with manual data transfers. He collaborates remotely with clients in Paris and Brussels, relying heavily on shared documents and video calls. The pressure to deliver measurable results for his clients, often app startups with tight budgets, is constant, driving his relentless pursuit of optimization and efficiency. He views his tool stack as a work in progress, always seeking better integrations.

Relationships

Vivien maintains a close-knit circle of friends, mostly fellow freelancers or entrepreneurs he met during his Master's program or through industry events. He has a good relationship with his parents, who live in Lyon, and calls them weekly. His professional network is primarily online, with a few key contacts in Brussels he meets with quarterly when visiting clients.

How they decide

Vivien is a highly analytical and research-driven decision-maker. He meticulously gathers data, compares options, and weighs pros and cons before committing. He's not impulsive and prefers to understand the underlying mechanics of any tool or process before adopting it. He values evidence of effectiveness and ROI above all else, often running small-scale tests himself before making larger investments.

How they sound

Speaks with a clear, measured cadence, often using precise business and marketing terminology. His French is fluent and professional, with a slight Parisian accent. He avoids overly casual slang or emotional language, preferring direct and factual communication. When discussing technical aspects, he can become quite detailed. He tends to use phrases like 'from a performance perspective,' 'the data suggests,' and 'optimizing for...' He is not prone to hyperbole.
