Waves of Change 2024: Bridging Sustainability, Innovation, and Coastal Challenges

Waves of Change 2024: A Platform for Coastal Sustainability

Initiated in 2018, Waves of Change provides a space for like-minded organizations to address sustainability in coastal cities. Originally sparked by the lack of focus on sustainability in events, the forum brings together diverse disciplines for impactful change.

Key Themes at the Waves of Change Forum 2024

At the Waves of Change Forum 2024, key topics will focus on addressing pressing challenges facing coastal cities. This year’s themes align with the Tideline Startup Challenge and include categories such as Water Management, Waste Management and Circularity, Sustainable Mobility, Energy Transition, Sustainable Tourism and Local Communities, Biodiversity and Public Health, and Coastal Adaptation to Sea Level Rise. In addition to the challenge, the forum will align with the upcoming UN Ocean Conference, often referred to as a “COP for the Ocean.” The event will also delve into the topic of sustainable finance, with contributions from the forum’s involvement in the Blue Economy (sustainable use of ocean resources for economic growth, improved livelihoods, and jobs while preserving the health of ocean ecosystem) and Finance Forum steering committee meetings.

A Unique Experience: Facilitating Collaboration and Sustainability

The forum is more like a team-building event for impact-driven organizations. Attendees describe it as a platform where human connections lead to action, differentiating it from typical conferences. The event is designed to facilitate networking and collaboration among attendees, with the event structured specifically to foster connections and productivity. Attendees can expect a unique experience, where interactive sessions, workshops, and panels are curated to encourage participants to choose their own adventure, much like surfers picking waves. The forum offers themed tracks, allowing individuals to craft their own schedules based on personal interests and opportunities.

Sustainability is woven into the very fabric of the forum’s operations and ethos. The organization is committed to Sustainable Development Goal 17, focusing on partnerships for the goals. The forum’s logistics prioritize reusability, borrowing, and repurposing over buying or building. Sustainability is not just a theme but a daily practice, integrated into every aspect of the event, from breakfast to dinner.

Innovative Solutions and Success Stories

The Waves of Change 2024 Forum will present numerous case studies and projects. These highlight successful strategies in ecological transition and community resilience. Noteworthy examples include the collaborative work by Tomorrow’s Foundation with Ksapa in India and Africa, the Movin’On Communities of Interest on sustainable mobility, and the Ocean Risk Resilience Coalition. The forum will also highlight the Blue Finance Coalition, the 1000 Ocean Startups investment framework, and the Blue Food Playbook project by 2050. Additionally, it will celebrate 20 years of incredible work saving French Polynesian turtles by Te Mana o Te Moana. The forum will also discuss the displacement of the town of Miquelon to address sea level rise threats.

The forum will also showcase innovative tools and technologies that have the potential to transform sustainability and social change. While many of these solutions will emerge from original collaborative proofs of concept or task forces created during the event, the focus will be on blending innovation with preservation, integrating both high and low-tech solutions to address global challenges.

Addressing Coastal Challenges with the Tideline Startup Challenge

The Tideline Startup Challenge is a key feature of the Waves of Change 2024 Forum. It focuses on addressing pressing challenges faced by coastal cities. The challenge invites micro-consortiums of at least two startups and one city. Together, they craft original solutions, resulting in Proofs of Concepts that are low cost, investment-ready, and scalable. This initiative reflects the broader spirit of the forum. Collaboration and partnerships are key to addressing common challenges in tangible ways.

While the applications for the Tideline Startup Challenge are now closed, the finalists are currently being selected. The most promising solutions will be evaluated during the forum, with plans for funding and deployment.

What’s Next for Waves of Change

With the upcoming edition of Waves of Change just around the corner, the forum’s immediate focus is on the event’s successful execution. After the forum, attention will shift to implementing the solutions and initiatives generated. The forum will also continue work on the Basque Coast preservation project and the Waves Talent Program, which aids corporations in transition.

Waves of Change will contribute to the Movin’On Connect Summit on sustainable mobility in November. The forum is also looking forward to a partnership with ChangeNOW Summit in 2025. The focus will be on sustainable coastal cities ahead of the UN Ocean Conference. Visitors to France in April 2025 will have the opportunity to attend both ChangeNow and Waves of Change within a week, with a weekend break in between for relaxation.

In early June 2025, a selection of Waves of Change partners, projects, and collaborations will feature in the UN Ocean Conference in Nice and the Blue Economy and Finance Forum in Monaco.

AI fintech funding
Fundraising 2 days ago

The European fintech sector continues to attract early-stage capital, with AI-powered financial modelling emerging as a particularly active frontier for investor interest. As finance teams across high-growth organisations grapple with the limitations of static spreadsheets and fragmented planning tools, a new generation of startups is building intelligent infrastructure to replace legacy workflows. Stockholm-based Galdera Labs has now entered this space with a €1.5 million pre-seed round to develop an AI-native financial modelling platform designed for growth-stage finance teams. The funding will support platform development, reasoning infrastructure buildout, and an initial customer rollout targeting fast-growing companies with complex financial operations. Galdera’s platform combines a high-performance calculation engine with a semantic memory layer that links financial data directly to underlying business context, assumptions, and strategic decisions — enabling finance teams to query models in natural language and simulate complex scenarios in minutes rather than weeks. Klarna Veterans Back AI Financial Modelling Vision The pre-seed round was led by J12 Ventures, with participation from Antler and a roster of angel investors drawn from notable European technology companies including Klarna, DeepL, Stripe, and Plata. The investor composition reflects strong confidence in the founding team’s pedigree and the market opportunity for intelligent financial planning infrastructure. Galdera’s three co-founders — Evan Rumpza (CEO), Mattia Scolari (CFO), and Giovanni Casula (CTO) — met at Klarna during the fintech giant’s most intensive growth phase. Responsible for financial planning across 26 markets, the team experienced first-hand how manual processes and fragmented Excel models struggled to keep pace as business conditions shifted faster than traditional models could be rebuilt. To manage the complexity, they built an internal system at Klarna that replaced the static planning cycle with a continuously updated model — enabling what previously required large analyst teams to be handled by just three people, supporting the company through both capital raises and IPO preparations. The lessons learned from that experience became the foundation for Galdera Labs. “We’ve personally sat with 50 spreadsheets at two in the morning using tools that were supposed to solve the problem but didn’t. That is the infrastructure we are building with Galdera,” said Evan Rumpza, CEO and co-founder of Galdera Labs. Building AI Finance Tools for the Next Generation of CFOs The market for AI finance tools and financial modelling software is evolving rapidly as organisations demand more dynamic planning capabilities. Traditional spreadsheet-based approaches, while flexible, often create fragmented workflows where assumptions become outdated and institutional knowledge is lost between budget cycles. Galdera’s platform addresses this gap with a two-layer architecture: a powerful calculation engine capable of handling large data volumes, paired with a semantic memory layer that preserves the reasoning behind financial decisions over time. The platform is designed to function as an always-on financial forecast that automatically updates as business conditions change. Users configure scenarios once, and the model recalculates impacts across revenue, costs, margins, and other key metrics in real time. This approach positions Galdera within a growing wave of European fintech startups applying artificial intelligence not merely as an overlay on existing tools, but as a foundational redesign of how financial planning operates. With the launch, Galdera is opening its platform to its first customers: fast-growing companies and organisations with complex operations where the pace of decision-making has outgrown the tools finance teams traditionally rely on. Early adopters already include companies such as DeasyLabs, Unify, and Counsel. The pre-seed round positions Galdera Labs at an early but promising stage in a sector where demand for intelligent, context-aware financial infrastructure is accelerating across European markets. As AI continues to reshape enterprise workflows, the intersection of financial modelling and machine reasoning represents a significant opportunity for startups capable of delivering genuine operational value to scaling businesses.

AevoLoop circular plastics recycling technology funding announcement with plastic waste processing
Fundraising 2 days ago

The sustainable consumer goods sector is witnessing growing investor appetite as environmentally conscious brands prove they can combine purpose with profitability. East London-based Allday Goods, the cult kitchen knife brand that transforms plastic waste into chef-quality blades, has raised £765,000 in a seed round led by FIGR Ventures to scale its operations from artisan favourite to mainstream kitchen staple. Founded in 2021 by ex-chef Hugo Worsley, Allday Goods manufactures kitchen knives with handles crafted entirely from recycled plastic waste — sourced from Maldon Salt buckets, milk bottle handles, discarded plant containers, and fishing nets washed up on British shores. The brand, which started in Worsley’s parents’ shed using a repurposed toastie maker, has already achieved profitability with minimal external investment. Products consistently sell out within minutes during online drops, and queues have formed at London pop-ups, reflecting a level of consumer demand that few sustainable brands can match at this stage. FIGR Ventures Leads Seed Round with Sustainability-Focused Backers The £765,000 round was led by FIGR Ventures, with participation from Anotherway Ventures, Machroes Holdings — the family office of Lord Mervyn Davies — and angel investor Tom Gozney, founder of the premium pizza oven brand Gozney. The investor mix signals confidence in Allday Goods’ ability to bridge the gap between sustainable manufacturing and scalable consumer product design. Allday Goods’ knives pair handles made from 100% recycled food-grade polypropylene with British and Japanese steel blades. The company collects, cleans, shreds, and remoulds plastic waste into distinctive, colourful handles that carry visible traces of their former lives — a design choice that has become central to the brand’s identity. Each knife effectively diverts plastic from landfill whilst delivering professional-grade performance. Worsley commented on the raise, noting that the team had built the brand slowly and intentionally, and that securing backing from investors they genuinely admire represents a significant milestone for the next chapter of growth. From Cult Following to Mainstream Market Opportunity Allday Goods has already demonstrated significant commercial traction without substantial marketing spend. The brand’s high-profile collaborations with Ottolenghi, Soho House, Maldon Salt, Kerrygold, and Paul Smith have positioned it at the intersection of culinary craftsmanship and design culture. Features in The World of Interiors and Esquire have further cemented its reputation among discerning consumers who value both aesthetics and environmental responsibility. The fresh capital will be deployed to scale production capacity, expand the product range, and accelerate the transition from limited-edition drops to consistent retail availability. The challenge for Allday Goods will be maintaining the artisan quality and brand mystique that fuelled its cult status whilst meeting the demands of a broader consumer base — a tension that many direct-to-consumer brands have struggled to navigate. The broader sustainable kitchenware market continues to attract both consumer interest and investor capital across Europe. As regulatory pressure on single-use plastics intensifies and consumers increasingly seek products that align with their environmental values, brands like Allday Goods that demonstrate genuine circularity in their manufacturing processes are well-positioned to capture meaningful market share.
