Joaquín Sepúlveda
Product Manager
I build products that people love.
I'm a data-driven product manager with six years of experience based in Santiago, Chile. I focus on outcomes that matter to the business, always taking into account the voice of the customer.
Experience
I began my career at an early-stage startup, where I wore multiple hats before transitioning into product management. As the company scaled from 1 to 60 enterprise customers, I managed product strategy and execution to grow revenue 15x, mastering prioritization frameworks and stakeholder alignment to focus on high-impact initiatives. Later, I pivoted to cybersecurity, leading product strategy for teams specializing in deep/dark web monitoring, breach detection, and third-party integrations — always with a focus on measurable impact, rapid execution, and balancing technical depth with business outcomes.

Referrals
I had the pleasure of working with Joaquín on our Cyber Threat Intelligence (CTI) team, where he served as a Product Manager. From day one, Joaquín brought a rare combination of curiosity, product and UX intuition, and strategic clarity that made a significant impact on both the product and the team.
During our time working together, Joaquín led several key initiatives, including the development of a complex deep and dark web scraper and a Telegram scraper, where he successfully translated complicated datasets into intuitive, high-impact product capabilities. He understood not just what our users needed, but why—which allowed him to deliver features that were both technically sound and deeply aligned with customer goals.
Joaquín excels at working across functions. Whether collaborating with engineering, data science, threat research, or customer-facing teams, he's clear, thoughtful, and outcome-oriented. He also brings a calm, focused energy to product discussions—always advocating for the user while keeping the broader strategy in view.
Beyond his technical and product chops, Joaquín is just a fantastic teammate. He's inquisitive, humble, and committed to continuous improvement, which makes him a strong contributor to any organization—not just in terms of delivery, but in shaping a positive, high-performing culture.
If you're considering working with Joaquín, know that you're engaging with a product manager who has a good grasp of cybersecurity at a deep level and knows how to deliver real value in a complex, high-stakes environment.
