happyhotel secures €6.5M Series A to scale its hotel AI
happyhotel, a European revenue management platform for independent hotels, has raised €6.5 million in a Series A funding round led by Reimann Investors. Existing backers Start-up BW Innovation Fund (managed by MBG Baden-Württemberg), seed + speed Ventures, and family office Wecken & Cie. also participated.
Co-founder and CEO Rafael Weißmüller said the company is not disclosing its valuation, adding that happyhotel has now raised €8.8 million in total funding to date. The new capital will be used to accelerate European expansion and advance the company’s Commercial AI agent, aimed at automating pricing and distribution decisions for hotels.
Targeting independent hoteliers under pressure
Independent hotels face rising operating costs, volatile demand, staffing shortages, and increasing dependence on OTAs (online travel agencies) that can compress margins. According to Weißmüller, many properties lack the internal expertise and capacity for professional revenue management.
happyhotel says it combines artificial intelligence with human revenue expertise to automate price optimisation. The company claims customers typically see an average 15% revenue increase after adoption. It also reports optimising pricing and distribution for more than 50,000 rooms across 12 countries, managing over €1 billion in annual hotel revenue through its platform.
From prototype to “autonomous” commercial agent
Founded in 2019 by Sebastian Kuhnhardt, Marius Müller, and Rafael Weißmüller, the startup began after Kuhnhardt identified inefficient pricing practices during his hotel management studies and tested data-driven models in his family’s hotel. Over the next year, the company plans to evolve from software into an autonomous commercial agent that analyses market and demand data in real time while incorporating internal expert input.
happyhotel will also push deeper into Europe, with a focus on the UK, France, and Austria. Hans-Christian Perle of Reimann Investors said the firm backed the company for its experienced team, measurable customer value, and a market that remains “only partially tapped.”
