Ruya Ventures Research
Investment Thesis
Ruya Ventures is a London-based solo-GP venture capital firm founded by Rick Hao to back European deep tech founders "from day zero." The firm's public positioning is unusually specific: it does not present itself as a generalist early-stage fund but as a specialist that goes deep into a small number of deep tech value chains where Hao has already built conviction through prior academic research relationships and past investment experience. The stated belief driving the fund is that deep tech companies rarely fail because the underlying science is wrong; they fail because nobody helps the founding team cross the gap between a working lab prototype and a product that can be manufactured at scale, industrialised, and sold into a real market. Ruya explicitly positions itself as the investor that does the unglamorous post-cheque work: commercialisation strategy, manufacturing pathways, supply chain construction, and go-to-market support, rather than a passive capital provider.
Sector Focus
The firm's investment focus spans six declared value chains: Battery, Artificial Intelligence, Robotics, Materials Science, Novel Computing, and Semiconductors. Ruya describes itself as technology-agnostic across software and hardware within those chains, selecting for the ambition and difficulty of the problem rather than a particular modality. In practice its current portfolio skews hardware and infrastructure: a vertically integrated battery-to-grid energy platform and a compute-cooling hardware company, alongside stealth-stage bets in AI, robotics, and semiconductors.
Stage Focus
Ruya is a day-zero, pre-seed investor. The firm states it "often invests in the first funding round and even before incorporation," working alongside founders from the earliest stages of company formation, including helping shape the initial strategy and build the founding team.
Check Size
No specific check-size range is disclosed publicly. The $50M fund is explicitly structured for a highly concentrated portfolio (public reporting cites a target of roughly 20 companies worldwide), implying meaningful reserves for follow-on rounds rather than a high volume of small initial checks, but exact figures were not confirmed from primary sources.
Lead Tendency
Ruya positions itself as the most engaged investor at the moments that matter most: forming initial strategy, building early teams, setting up global supply chains, and expanding into global markets. Combined with its willingness to invest pre-incorporation, this points to a lead/anchor role in the rounds it enters rather than a passive follower position.
Recent Activity
Ruya Ventures launched in October 2025 and spent roughly nine months operating partly in stealth before closing its debut fund. In April 2026, while still largely in stealth, the firm was named "Newcomer of the Year" at the EUVC Summit & Awards, judged by a panel including Adams Street, GP Bullhound, HSBC, Isomer Capital, LGT, and Sofina. In June 2026, its first investment, WLF Energy, emerged from stealth at Battery Show Europe in Stuttgart. In July 2026, Ruya announced it had closed an oversubscribed $50M (reported elsewhere as €43M) debut fund, having turned away additional LP capital to preserve its concentrated strategy; Aldea Ventures is credited as the fund's first LP. By the fund-close announcement, Ruya said it had already deployed into five companies across its core sectors. The firm was also named a Founding VC of ETH Investor Connect, a new program giving a small group of European institutional investors embedded access to ETH Zurich's founder and research ecosystem.
Portfolio Highlights
Two portfolio companies are publicly named on Ruya's own site: WLF Energy (wlfenergy.de), a vertically integrated clean-energy platform spanning generation, storage, management, intelligence, and trading, with existing commercial battery and energy operations across the UK, Germany, the Nordics, Turkiye, and the US, a proprietary battery management system strengthened by the acquisitions of Cellovate GmbH and VersaPowr's BMS business, and a strategic partnership with Farasis Energy; and MegaCool Technologies (megacool-technologies.com), a hardware company building cooling infrastructure tailored to modern AI/compute workloads. In addition, the firm's site describes (without naming) three to four additional stealth-stage investments spanning real-time speech translation AI, sodium-ion battery technology, industrial-intelligence robotics infrastructure, and PCB manufacturing for regulated industries.
Team
- Rick Hao, Founder and Managing Partner: former Head of Deep Tech at Speedinvest, where public reporting credits him with having backed 30+ deep tech companies before founding Ruya. Ruya is currently run as a solo-GP vehicle, with Hao as the sole named investment partner on the public site.
Decision Process
Ruya is structured and marketed as a solo-GP fund, meaning investment decisions run through Rick Hao rather than a multi-partner investment committee.
Founder Preferences
The firm looks for founders tackling meaningful, technically difficult problems "that others won't tackle," and for teams willing to partner with an investor before incorporation on strategy, team-building, and go-to-market rather than treating the investor as a passive check-writer. Founders coming out of strong research environments (the firm specifically highlights ETH Zurich as a source of founders who are "already thinking about manufacturing pathways and supply chains while still finishing their PhDs") are called out as an ideal profile.
Geographic Focus
Ruya is rooted in Europe (headquartered in London) but describes itself as "global by design," with a network spanning industry, academia, and capital across Europe, the US, and Asia, and explicit intent to help portfolio companies expand from a European base into global markets.
