Investment-fund research reviewed 2026-10-06. Publicly identified funds, dates, amounts and fundraising status are below. Undisclosed commitments remain unknown; this is not a complete register of private SPVs or parallel entities.
Fund size
| Field | Finding | Evidence |
|---|---|---|
| Latest-known vehicle | Debut fund; external institutional profile calls it **Ruya Ventures Fund I** | S1; S7 |
| Size and currency | **US$50 million** | Official close announcement S1; independently reported by S2 and S4 |
| Status | **Closed, oversubscribed**, with extra LP capital declined; this is a completed raise, not a target | S1, dated 2026-07-01 |
| Vintage / chronology | Firm says launched **October 2025** and completed the raise within a year; announcement **2026-07-01** | S1 |
| Exact legal close date | Not verified. PEI public fund row says **June 2026**; July 1 is the announcement date | S7 versus S1; these need not conflict |
| AUM / check sizes | Neither total AUM nor reliable official investment ticket range was established | Adex values null; checked official announcement and homepage |
Searches for subsequent fund announcements and September 2026 developments did not find a newer fund. Treat this as latest-known, not proof that no later vehicle exists. The official announcement thanks Aldea Ventures as the first LP. [S1] External euro conversions should not replace the original US-dollar denomination.

# Ruya Ventures
- **Exact Adex ID:** `RuyaVentures`
- **Canonical Adex URL:** https://adex.page/firms/RuyaVentures
- **Research date / access date:** 2026-10-06
- **Status:** research complete with the limitations below; no Adex changes made.
Ruya is Rick Hao’s London-based solo-GP deep-tech investor. Its latest-known publicly announced fund is a **closed US$50 million debut fund**, announced **1 July 2026**. Its supported mandate is day-zero / pre-seed investing, often before incorporation. Two named investments are **MegaCool Technologies** and **WLF Energy**. No verified neurotech investment was found. [S1, S2, S3, S4]
## Starting evidence: Adex MCP and NFX Signal
The exact-ID record was read first from the saved read-only Adex MCP Search response, `data/research/_sources/RuyaVentures.adex.json`, retrieved **2026-10-06T19:28:52.699Z** from `http://localhost:3000/mcp` ; arguments were Org search for `Ruya Ventures` with label `Match`. It identifies Rick Hao as Founder and Managing Partner; describes a Europe-rooted, concentrated deep-tech strategy; has null founding and check-size fields; and lists MegaCool Technologies, **WFL Energy**, and five stealth placeholders. Every investment lacks a date and amount. Its evidence dates to 14 September 2026 and references the firm homepage and fund announcement. This baseline is a lead, not independent verification.
No NFX Signal URL was present. Searches for `site.signal.nfx.com "Ruya Ventures"`, `site.signal.nfx.com "Ruya" "Hao"`, and `site.signal.nfx.com "Rick Hao"` did not locate an attributable Signal profile. Direct attempts to read the **candidate, unverified** URLs https://signal.nfx.com/firms/ruya-ventures and https://signal.nfx.com/investors/rick-hao returned tool access errors. Their existence is not established; do not enter these guessed paths as verified profiles. No Signal stage, check-size or portfolio claims were available to use.
## Fund size
| Field | Finding | Evidence |
|---|---|---|
| Latest-known vehicle | Debut fund; external institutional profile calls it **Ruya Ventures Fund I** | S1; S7 |
| Size and currency | **US$50 million** | Official close announcement S1; independently reported by S2 and S4 |
| Status | **Closed, oversubscribed**, with extra LP capital declined; this is a completed raise, not a target | S1, dated 2026-07-01 |
| Vintage / chronology | Firm says launched **October 2025** and completed the raise within a year; announcement **2026-07-01** | S1 |
| Exact legal close date | Not verified. PEI public fund row says **June 2026**; July 1 is the announcement date | S7 versus S1; these need not conflict |
| AUM / check sizes | Neither total AUM nor reliable official investment ticket range was established | Adex values null; checked official announcement and homepage |
Searches for subsequent fund announcements and September 2026 developments did not find a newer fund. Treat this as latest-known, not proof that no later vehicle exists. The official announcement thanks Aldea Ventures as the first LP. [S1] External euro conversions should not replace the original US-dollar denomination.
## Investment stages and geography
**Current verified strategy:** invest in the first financing round, including before legal incorporation; support lab-to-market development. The investee’s official biography calls Ruya a **pre-seed** fund, and Axios also describes it as pre-seed. Europe and the UK are the principal focus within a global approach. [S5, S6, S4, S2]
Seed is listed by PEI and appears in the firm’s public LinkedIn tags, but explicit official pre-incorporation/first-round language is stronger evidence than a broad stage taxonomy. **Pre-seed is firmly supported; seed is additionally reported, with lower certainty.** [S7, S8] No evidence established a current Series A/B initial-investment mandate. Founder testimonials about Rick’s previous Seed/Series B experiences are not evidence of Ruya investing at those stages. [S5]
## Previous deep-tech investments
| Company | Technology and classification | Firm attribution and transaction detail | Supporting sources |
|---|---|---|---|
| **MegaCool Technologies** (`MegaCoolTechnologies` in Adex) | Direct-to-chip liquid cooling, engineered cold plates and digital-twin thermal design for advanced computing. Physical thermal engineering supports classification as deep tech; the firm’s AI category does not mean it is ordinary AI SaaS. Performance figures on the company website are company claims, not independently validated. | Listed in Ruya’s own company section and in reporting on its initial investments. Investment occurred by the 2026-07-01 launch reporting; exact date, round stage, round size and Ruya check are **undisclosed in checked sources**. | S5 official investor portfolio; S3 dated 2026-07-01; S9 official company site, undated |
| **WLF Energy** (**Adex says WFL Energy**, ID `WFLEnergy`) | Integrated battery energy storage, grid control, proprietary energy management and generation-to-grid infrastructure. Strong energy/hardware relevance, although publicly inspected material does not isolate a patented scientific breakthrough; use “battery/energy infrastructure” rather than inventing chemistry/IP claims. | Ruya names it in its portfolio (with WFL spelling); reporting names WLF. WLF’s official team page identifies Hao as Ruya founder and supervisory-board member. Investment reported by 2026-07-01; exact round/date, amount and check **not found**. | S5; S3 dated 2026-07-01; S6 and S10 official investee pages, undated |
The current official company section also describes unnamed **speech translation**, **sodium-ion batteries**, **industrial intelligence/robotics**, and **PCB manufacturing** projects. These are sector evidence, not named investees; company identities and transaction facts remain unknown. Battery chemistry is a clear deep-tech rationale; novelty of the speech/industrial projects cannot be assessed from short labels. [S5]
**Do not attribute Rick Hao’s former Speedinvest portfolio to Ruya.** Reporting explicitly places his earlier 30-plus-company track record at Speedinvest. [S3] Ruya testimonials can reflect those earlier relationships; they do not by themselves establish Ruya investments.
## Previous neurotech investments
**No verified neurotech investment found in the sources checked.** Checked the exact-ID Adex baseline, current official portfolio/thesis, launch reporting, named investee websites and searches for Ruya with neurotech, brain and neuroscience. No named brain-computer-interface, neural sensing/stimulation, or other direct neurotechnology investee was identified. AI, speech translation and an energy platform’s metaphorical “brain” are not neurotech evidence. Stealth investments make the portfolio incomplete; this finding must not become “Ruya has no neurotech investments.”
## Conflicts, gaps and handoff for a later Adex review
1. **Company spelling / exact-ID issue:** official investee site and reporting say **WLF Energy**, whereas Adex’s existing company ID is `WFLEnergy` and Ruya’s own portfolio says WFL. Review company identity and aliases before any correction; do not silently invent or replace an exact ID. Its official domain is **wlfenergy.de**. [S3, S5, S6, S10]
2. **Portfolio count:** July announcement says five investments; Adex stores seven rows including a generic undisclosed placeholder; current homepage has repeated stealth text and no definitive total. Different dates or webpage extraction artifacts could explain this. Do not infer seven distinct completed investments, or create a company for the generic placeholder. [S1, S3, S5]
3. **Fund dating:** distinguish October 2025 launch, externally reported June 2026 close, and July 1 announcement. Confirm legal fund name/date from additional primary material if schema requires precision. [S1, S7]
4. **Missing transaction details:** preserve unknown investment amounts/dates/stages. A pre-seed fund mandate does not verify that every historical transaction was pre-seed.
5. **Seed and check sizes:** retain stage confidence distinctions; do not import directory ticket estimates without official support.
6. **Access limits:** NFX profiles were not found/verified. Sifted’s opening passage was readable but most body text was obfuscated/paywalled; only the readable introduction supports the cited fund/geography findings. PEI also contains generic placeholder text and locked fields; use its specific visible fund row cautiously. [S2, S7]
7. This is a research handoff only. No database, firm, company or investment records were updated.
