happyhotel, an Offenburg-based HotelTech startup offering revenue management software for the hotel industry, today announced the closing of its €6.5 million Series A funding round to develop AI agents for hotels.
The round was led by venture capital fund Reimann Investors. Existing investors also participated again, including Start-up BW Innovation Fund (managed by MBG Baden-Württemberg), seed + speed Ventures and the family office Wecken & Cie.
“We are not building our system for the revenue manager – we are automating the tasks of a revenue manager. Our goal is to enable professional revenue management for every hotel and fully automate the selling of hotel rooms so hoteliers can focus entirely on their guests,” explains Rafael Weißmüller, CEO of happyhotel.
Recent EU-Startups coverage shows that happyhotel’s Series A sits within a broader set of European funding rounds in 2025 and 2026 involving hotel operations, revenue management software, and AI-enabled hospitality tools. During this period, EU-Startups reported funding rounds ranging from sub-€1 million pre-Seed investments to larger funding rounds for hospitality platforms.
The substantial funding rounds include Amsterdam-based Mews’ €255 million ($300 million) Series D funding round in January this year, Barcelona-based Amenitiz’s €38.9 million ($45 million) mix of Series B funding and financing, and London-based HospitalityTech startup Nory’s €31 million Series B funding to transform restaurant operations with AI.
Another large funding round reported in 2025 was secured by Madrid-based HotelTech scale-up Room00. The company announced funding of up to €400 million to support the expansion of its urban hospitality platform across Europe.
Smaller funding rounds reported during this period include Austrian TravelTech startup chatlyn’s €8 million Series A funding to develop AI-driven hotel communication software, as well as sub-€1 million funding rounds raised by London-based Inntelo AI and Amsterdam-based Toppi.
Founded in 2019 by Rafael Weißmüller, Sebastian Kuhnhardt and Marius Müller, happyhotel helps hotels optimise pricing strategies, identify market opportunities and achieve sustainable revenue growth.
According to the company, hotels are increasingly facing more pressure. It notes that several hotels struggle to operate profitably due to rising costs, volatile demand, staff shortages, and an increasing reliance on online booking platforms. happyhotel claims to support hoteliers with automated price optimisation, combining artificial intelligence with human expertise.
With the fresh capital, the company will accelerate its expansion across Europe and invest in the further development of its commercial AI agent. happyhotel claims that the AI agent supports users in making the right pricing and distribution decisions and will gradually take over increasingly complex tasks.
The AI agent analyses market and demand data in real time and is complemented by a team of in-house revenue managers for fundamental strategic questions.
The German startup reports that it currently optimises the distribution of more than 50,000 hotel rooms across 12 countries and achieves an average hotel revenue increase of around 15%. The company says it manages more than €1 billion in annual hotel revenue.
