In this episode of the DevReady Podcast, host Anthony Sapountzis is joined by Stefan Pagacik, Founder and CEO of Ampresta and Executive Advisor at 528Connect. A systems thinker and long-time advocate for leveraging market dynamics to accelerate decarbonisation, Stefan has dedicated his career to creating innovative tools that turn climate commitments into measurable financial outcomes. With a rich background spanning media, technology, and sustainability, including senior roles at Apple and Adobe, he has spent the past 17 years focused on helping businesses and investors move beyond traditional sustainability reporting to actionable, impact-driven strategies. Stefan’s mission is clear: to make climate resilience a core component of every business model by bridging the worlds of carbon metrics and capital markets.

Stefan begins by sharing his journey from a dual career in media and entertainment to becoming a product developer and senior leader, highlighting how his self-taught technology expertise enabled him to work closely with developers and deeply engage with customers. He recounts how this balanced approach helped him identify pain points and design scalable solutions, ultimately laying the foundation for his entrepreneurial pursuits. His early experiences at large corporations inspired him to seek more meaningful, hands-on roles in smaller companies, where he felt a greater sense of connection and purpose. This drive led him to focus on sustainability technologies that align with his belief in creating a positive legacy for the planet.

Reflecting on repeated frustrations expressed by CEOs over the ineffectiveness of traditional sustainability reporting, Stefan describes how these insights became the catalyst for founding Ampresta. He explains that most reports fell short, taking organisations only halfway towards tangible impact, and identified a critical need to integrate decarbonisation metrics with financial data. By bridging this gap, Stefan aims to transform sustainability from a box-ticking exercise into a core business strategy. Through conversations with asset managers struggling to build decarbonisation-focused financial products, he realised the urgency of creating tools that help companies and investors measure and monetise sustainability outcomes.

As the discussion deepens, Stefan shares the challenges of building a credible financial model without a background in financial modelling, revealing how he dissected companies into functional business units to pinpoint where decarbonisation and financial data intersect. He details early setbacks with dummy data and highlights more promising results from real-world tests in Manhattan flood zones, which validated his approach. Stefan underscores the need to adapt the model for industries like insurance and banking, stressing that quantifying physical and financial risks is essential to motivate proactive investment, especially given the unpredictable nature of climate events.

In the closing moments, Stefan reflects on the cultural lessons he has carried into Ampresta, from avoiding the pitfalls of careless spending to prioritising clear communication that resonates beyond technical audiences. He emphasises the importance of addressing customers’ fears, arguing that trust is built not through technology alone but by demonstrating a deep understanding of their challenges. Above all, Stefan shares that his unwavering North Star is integrity, which he believes must guide every action and decision. He candidly describes challenging his team to commit fully as they approach pivotal projects, recognising that sticking to their principles will determine whether they seize the moment or let it slip away.
