Greenwave Capital is a microfund dedicated to early-stage Dutch startups, aiming to accelerate the transition to a regenerative and sustainable future. We provide startups with seed capital to initiate and expedite this green wave, offering ‘smart capital’: a blend of funding and expertise.

At Twin AI, we started with a simple observation: writing grant applications is often a stressful race against the clock. We see teams struggle with deadlines, incomplete input, and endless review rounds. It drains time, energy, and focus from what truly matters: quality. There had to be a smarter way. That’s why we developed Twin Docs A 𝐩𝐥𝐚𝐭𝐟𝐨𝐫𝐦 that makes writing grant applications 𝐭𝐞𝐧 𝐭𝐢𝐦𝐞𝐬 𝐟𝐚𝐬𝐭𝐞𝐫, without compromising on quality. It brings structure, focus, and control to a process that still feels like a constant race against time for many professionals. Behind Twin Docs stands 𝐓𝐰𝐢𝐧 𝐀𝐈, a team with deep insight into context and precision. That knowledge enables us to develop technology that doesn’t just generate text, but understands, adapts, and performs reliably - time after time. 𝐖𝐡𝐚𝐭 𝐢𝐭 𝐝𝐞𝐥𝐢𝐯𝐞𝐫𝐬: - Less stress, more structure - Higher success rates - Better collaboration between stakeholders - And most importantly: more time for quality We believe technology only becomes valuable when it helps people perform better: faster, simpler, and with confidence.

Arches Capital is a fast-growing group of business angels that is bridging the gap between Venture Capitalist (VCs) and how angels operate today, by joining the best of both worlds for our members. Our community strives to bring superior deal flow, professional knowledge and lower risk profile to our participating angel investors. We further distinguish ourselves in the way profits are generated and shared, and how our angels interact with their investees (the startups) and with each other. For this we are building the leading platform of actively engaged business angels that know how to operate and manage their investments in a professional and standardized manner. Operate like a VC, be an Angel We source, select and invest like a VC; We engage, care and inspire as the angel we are. We believe that by bundling smart capital (combine funding with real business knowledge and experience) with true engagement (actively working together to achieve rapid growth), we are able to ignite early stage companies on their path to success. Arches Capital invests in early stage and scaling companies. We differentiate itself from angel syndicates or funds by supporting the next growth stage as well: we aim to lead or contribute to follow-on investments of our successful portfolio companies. For general info or angel membership info please contact: info@arches.capital. For companies that seek funding: please check our website (http://arches.capital) for our preferences and prerequisites, and send your request, pitch deck and/or business plan to: fundme@arches.capital.

Every employee feels rushed, uncertain, or worn out by a full schedule at times. That’s human. Inuka is there for those moments, and for what comes next. We offer online coaching that helps people move forward via chat or video, whenever it suits them. Whether someone wants to manage stress better, feel more confident at work, or regain energy and focus, our certified coaches are there 💚 Personal, practical, and judgment-free support. For organisations, this means less absenteeism and drop-out, more engaged employees, and real-time, anonymous, measurable insights into team well-being. What do we see in practice? 1 in 2 users shows measurable improvement in mental well-being, and 1 in 3 moves away from elevated burnout risk. Our method was developed by psychiatrist Dixon Chibanda and validated by the WHO. Inuka means “to rise” in Swahili, which is exactly what we help people do. From Canon to YoungCapital, more and more organisations choose mental resilience with real impact. We’re proud to be a certified B-Corp, and 10% of our profits go to the Inuka Foundation. Everyone deserves a coach who truly works 🫶

We are dedicated to promote human nutritional security by securing high-quality pollination services for plantation farmers through the innovation of groundbreaking technology, addressing the alarming depletion of the global honey bee population.

A unique electro-mechanic device that serves the global beekeeping industry, solving a massive problem usually referred to as “CCD” or “Colony Collapse Disorder”. Our product consists of proprietary software, hardware, and service model, offering a valid and very efficient end-to-end solution to this problem, assisting not only the global beekeeping industry but the entire agriculture sector, all over the globe!
