  • Amenitiz

    Participated · Series B · Nov 2025

    Founded in 2017 in Barcelona, Amenitiz offers independent hoteliers a single cloud platform that unifies reservations, operations, payments, online presence, and revenue management. The company now serves more than 15,000 properties, up from 4,000 at the time of its 2022 Series A, and its customers have processed over €3 billion in bookings for 15 million guests in the past 18 months. Recent feature launches include AmenitizBoost for direct-booking marketing and PriceAdvisor for dynamic pricing, tools that the firm says can lift revenue by up to 20%. Amenitiz is doubling down on AI-driven product innovation to further automate hotel workflows and plans to introduce additional revenue-generating modules while expanding into new European markets. The platform targets the 750,000-plus independent hotels that constitute more than 80% of Europe’s hospitality market, aiming to give them the digital capabilities traditionally reserved for large chains. Historically, Amenitiz raised €620k in seed funding in 2019, €6.5 million in 2021, and €27 million in a 2022 Series A round, and it also acquired Ododo in 2022 to bolster its offering. Backed by a roster of international investors, the company positions itself as the default operating system for Europe’s independent hotel segment.

  • Marshmallow

    Participated · Equity · Apr 2025

    Marshmallow is a FinTech company that offers motor insurance and related products targeted at people who have recently emigrated to the UK. Founded in 2017 by Alexander and Oliver Kent-Braham and David Goaté, the company leverages proprietary technology and customer data to offer better value to newcomers. Marshmallow has provided cover for over one million customers and reports a turnover run rate of over €439 million. The business reached unicorn status in 2021 and employs around 700 people across London and Budapest. Marshmallow plans to expand its product offering to become a one-stop financial services provider for newcomers and to extend its proposition internationally beyond the UK. Marshmallow is a London-based car insurance provider that uses a wider set of data points and proprietary algorithms to offer more inclusive rates and attract a more diverse set of customers. The company has sold over 100,000 policies in the UK and grew policy sales 100% over the prior six months. Its average customer age is 20 to 40, and the team is exploring products aimed at even younger users. Marshmallow plans to deepen customer relationships by increasing engagement to help users become better drivers and by potentially cross-selling additional services. The startup is also progressing plans for international expansion, though target markets have not been announced. Marshmallow was co-founded by twins Oliver and Alexander Kent-Braham and David Goaté. Marshmallow builds mobile and web-native car insurance that uses a wider set of analytics and global data to assess risk for underserved segments, originally targeting expats who lack U.K. driving histories. The company’s algorithm incorporates international driving records rather than relying solely on national data. Marshmallow emphasizes diversity and inclusion in both its product focus and founding team. It was founded in 2018 and its leadership includes co-founders Oliver and Alexander Kent-Braham and third co-founder David Goate; Tim Holliday, a founding employee, serves as chairman. The startup plans to launch in additional countries and expand into more types of insurance over the next 18 months. With the latest funding it is valued at around $310 million, though the company is not disclosing customer numbers. Marshmallow is a U.K. insurtech building car insurance products for immigrants and expats who are poorly served by existing insurers. The startup is developing an underwriting system that aggregates global data rather than U.K.-only data and uses a proprietary algorithm intended to eliminate underwriting bias and compute more accurate prices for foreign-born drivers. It is starting with car insurance for foreign-born drivers and aims to offer fairer pricing and a transparent, convenient user experience compared with incumbents using legacy systems. The company was founded in March 2017 by Oliver and Alexander Kent-Braham and David Goate, and its team includes Tim Holliday, formerly Chief Underwriting Officer and MD of Personal Lines at Zurich. Marshmallow plans to launch later this year and targets foreign drivers who often face higher quotes after moving to the U.K. Financially, the company has raised $1.2 million in seed funding from Passion Capital and Investec Bank.
