“The real value isn't just in what we sell, but in understanding precisely what the market is willing to pay for it, every single day.”

Martín Prado Rincón, 40, is the E-commerce lead for a bustling secondhand sporting goods and games retailer based in Barcelona. His journey into this role began not with a passion for vintage jerseys or retro consoles, but with a sharp mind for economics honed during his university studies. After a few years in a more traditional corporate finance role, he found himself drawn to the dynamic, tangible world of resale, seeing it as a practical application of supply and demand principles. He joined the company four years ago when its online presence was nascent, primarily relying on ad-hoc listings. His mandate was clear: professionalize and scale their e-commerce operations. He has since transformed their digital footprint, establishing a consistent presence across Wallapop, eBay, and their own growing website. Martín’s daily reality involves an intense focus on data. He spends significant portions of his day meticulously tracking sold prices for a diverse range of items – from sought-after gaming consoles and collectible board games to specific models of athletic footwear and niche home goods. This constant monitoring feeds directly into a shared spreadsheet, a critical tool where he updates purchasing limits and refines sell-through expectations. These data-driven insights are the bedrock of the company's inventory acquisition strategy, directly impacting how much the purchasing team is authorized to spend. He views his role as a crucial bridge between the physical sourcing of goods and their digital realization of value. His economic background provides a framework for understanding market fluctuations, fee structures, and profit margins, allowing him to navigate the often-volatile secondhand market with a strategic, analytical approach. He’s not driven by a desire for personal wealth accumulation as much as by the satisfaction of optimizing a complex system and ensuring the business operates with maximum efficiency and fairness. His income, while comfortable, is reinvested into his personal life and savings rather than ostentatious displays. He values the stability and predictability his role offers, finding fulfillment in the continuous process of analysis and refinement, ensuring the company thrives in the competitive resale landscape.

Background & daily life

A day in their life

Martín's day begins at 6:30 AM with coffee and a quick review of overnight sales figures on his phone. By 8:00 AM, he's cycling to the office, mentally preparing for the day's tasks. The first few hours are dedicated to deep dives into sold comps for consoles and footwear, updating the shared forecasting sheet, and communicating any urgent pricing adjustments to the purchasing team. Lunch is a quick, healthy meal, often eaten at his desk while reviewing performance dashboards. The afternoon involves team check-ins, troubleshooting listing issues, and planning content for the company's own website. He leaves around 6:30 PM, often stopping for groceries or a quick chat with a vendor before heading home to Clara.

Lifestyle

Martín lives with his partner, Clara, in a comfortable, renovated ground-floor apartment in the Gràcia neighborhood of Barcelona. Their mornings are structured: coffee brewed with an Aeropress, a quick scan of overnight sales data, and then a brisk cycle commute to the office. Weekends often involve exploring flea markets for personal collection additions or visiting family in the nearby Penedès region. He's mindful of his spending, preferring quality over quantity and always looking for the best value, whether it's for household items or his personal tech upgrades. He enjoys the city's vibrant atmosphere but cherishes quiet evenings at home with Clara, often playing board games or watching documentaries.

Work life

As the E-commerce lead, Martín is the central nervous system for the company's online sales. His days are a constant juggle between monitoring Wallapop, eBay, and their proprietary website, analyzing sold comps for key categories like consoles, board games, and footwear. He meticulously updates a shared spreadsheet with pricing adjustments and sell-through forecasts, directly influencing purchasing decisions and inventory management for the 15-person team. The pressure is on to maximize profit margins while keeping inventory moving, especially with fluctuating market demand. He collaborates closely with the purchasing team and the warehouse staff, ensuring smooth operations from acquisition to listing.

Relationships

Martín is in a stable, long-term relationship with Clara, who provides a grounding influence and a different perspective on creative aspects of the business. He maintains strong professional ties with his direct reports and the purchasing manager, valuing their input and reliability. His influence stems from his consistent performance and data-backed recommendations, earning him respect rather than overt deference.

How they decide

Martín is a highly analytical and data-driven decision-maker. He meticulously researches comparable sales, market trends, and internal performance metrics before committing to a course of action. He prefers to gather all available information, weigh the pros and cons, and then make a calculated choice, often consulting with key team members for their insights but ultimately relying on his own analysis.

How they sound

Speaks with a measured, clear cadence, typical of educated Spanish speakers. Uses precise language, especially when discussing data or business metrics. Avoids excessive slang or overly casual phrasing in professional settings. His tone is generally calm and confident, even when discussing challenges. He might use occasional Catalan phrases when speaking informally with local colleagues.

Questions & answers

Martín Prado Rincón’s public research answers, newest questions first. Up to 10 per page.

  1. Looking at SoldStack (https://soldstack.fly.dev/): what price would make it a no-brainer for you, and at what price would you stop considering it? What would you expect to get for that money? Also say the maximum you would pay per month in USD (0 if nothing).

    The tool's concept is interesting for quickly checking sold comps, especially for items like consoles and board games that we move. The "no-brainer" price would be around $5-$10 per month for me to integrate it into my workflow for our own site and potentially for the Wallapop/eBay research. It would need to offer more than what I can quickly see on those platforms to justify a higher cost. Anything above $20 USD per month would start to feel too steep given our current margins and the free options available for basic checks, especially considering we're a 15-person company and not a massive enterprise. I'd expect to get clean, aggregated sales data with a high degree of accuracy and minimal filtering needed on my end.
