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 and stages
| Vehicle / metric | Amount and status | Date and supporting evidence |
|---|---|---|
| Fund I, originally GMG Ventures | **£42m** committed fund; Scott Trust sole investor according to LP reporting. This is a fund amount, not a cheque. | Firm founded 2017; precise fund close date not verified. [Scott Trust Endowment 2024 report](https://uploads.guim.co.uk/2024/09/17/The_Scott_Trust_Endowment_Ltd_report_2024.pdf ), published September 2024, calls the fund six years into its ten-year term and confirms the commitment. |
| Fund II / Mercuri II LP | **£50m raised/closed**, not merely a target; institutional LPs, British Business Bank cornerstone through Enterprise Capital Funds, with Scott Trust continuing as LP. | Official website says launched May 2023; [British Business Bank announcement](https://www.british-business-bank.co.uk/news-and-events/news/gmg-ventures-rebrands-to-mercuri-and-closes-a-50m-fund ), **2023-07-04**, confirms second fund raised. May launch and July announcement are different dates, not necessarily conflicting. |
| AUM | Official website reports **£92m AUM**; distinguish this self-reported aggregate from the £50m current vehicle and from available dry powder. | [Firm homepage](https://www.mercuri.vc/ ), undated, accessed 2026-10-06. |
| Initial cheque strategy | **£500k–£1m target**; 40% fund reserved for follow-ons; 6–8 new investments per year. | [Official approach](https://www.mercuri.vc/approach ), undated, accessed 2026-10-06. |
Fund II is the **latest-known publicly announced fund in the sources checked**. Searches for 2025/2026 newer funds and Fund III did not identify a verified subsequent close. [Companies House Mercuri II LP](https://find-and-update.company-information.service.gov.uk/company/LP023080 ) records registration on 2023-02-21 and former name GMG Ventures II LP through 2023-09-19; it does not establish fundraising size or remaining capital (undated current registry, accessed 2026-10-06).
Current stage evidence explicitly supports **pre-seed and seed**, leading rounds in UK media, entertainment and AI companies, with later follow-on financing. Historical late-stage portfolio participation should not broaden the new-investment mandate automatically. [Official approach](https://www.mercuri.vc/approach ). The 2023 LP announcement described leading seed rounds, while the current official strategy explicitly includes pre-seed. The current official GBP cheque target conflicts with Signal's substantially larger USD range; use official current strategy as stronger evidence and retain Signal values only as a dated comparison, not hard bounds.

The firm's [frontier-technologies thesis](https://www.mercuri.vc/frontier-technologies ) and [sector focus](https://www.mercuri.vc/sector-focus ), undated, include generative/agentic/multimodal AI, inference compute, embodied AI and spatial computing. Illustrative companies named on thesis pages are **not automatically portfolio investments**. Official portfolio page https://www.mercuri.vc/portfolio includes a separate Founders Factory mediatech cohort; do not treat all cohort companies as individual direct fund investments without transaction evidence.
## Neurotech
**No verified neurotech investment found in the sources checked.** Reviewed the snapshot, official strategy/portfolio and investment posts, Signal discovery profiles, and searches combining Mercuri/GMG Ventures with neurotech, brain and neuroscience. The named verified AI investments do not show brain sensing, neural interfaces, neurostimulation or direct nervous-system technologies. Literal Labs' comparison to artificial neural networks is computer science, not biological neurotechnology. Electric Twin simulates human behaviour rather than measuring neural activity. Faculty's healthcare/NHS applications and Mozart's music tools are not sufficient to classify as neurotech. This is a bounded public-source search, not proof that the firm has never invested in neurotechnology.
## Conflicts, gaps and later Adex review
1. Preserve `GoldiMercuri` exactly and Mercuri/GMG Ventures continuity. Avoid Mercury (bank/other VC), Mercuri International (sales training), or similarly named entities.
2. Review **Topship** attribution. The 2022 snapshot link is [TechCrunch, 2022-05-16](https://techcrunch.com/2022/05/16/nigerian-freight-and-e-commerce-provider-topship-raises-2-5m-from-flexport-and-yc/ ). [TechCabal, 2022-05-16](https://techcabal.com/2022/05/16/topship-closed-a-2-5m-seed-led-by-flexport-to-build-africas-flexport/ ) lists investors and names **Mercury CEO Immad Akhund**, not Mercuri. Mercuri attribution remains unverified and likely involves name confusion; do not retain it as confirmed without additional evidence.
3. **Electric Twin:** $14m is reported cumulative disclosed financing comprising $10m latest seed and earlier $4m pre-seed, not an additional $14m pre-seed on 2026-02-12. Snapshot round IDs 22362 and 36811 need amount/stage/date reconciliation. Mercuri source and founder evidence establish $10m follow-on; historical pre-seed 2024 date is GP-stated, exact day unavailable. Secondary databases inconsistently call it Series A; prefer official seed wording.
4. **Mozart/Mozart AI:** snapshot company IDs `Mozart` and `MozartAI` likely refer to the same venture. Its 2025-02-11 $6m record conflicts with the dated Balderton **2026-02-11** announcement; review duplicates rather than count three transactions.
5. **Signal/Signal AI** records also overlap in the baseline; portfolio exposure is officially claimed, but this research does not settle whether all growth-round entries describe the same financing. Do not infer growth-stage new-deal strategy from those entries.
6. **Literal Labs:** snapshot date 2025-06-02 matches update/reporting date; company announcement dateline is May 28. Primary evidence supports Mercuri **co-lead**, while snapshot marks non-lead. Preserve both date provenance and leadership caveat for review.
7. Initial cheque sizes now have official evidence. Any future suggested field update should describe a strategy target, not an absolute min/max. Signal discrepancy remains recorded above.
8. Exact ownership stakes, fund-by-fund allocation, investee check amounts, dry powder, fund close date for Fund I, and any unannounced Fund III remain unavailable. Team naming/title discrepancies need current official team review. No broad claim of exhaustive portfolio verification is made.

# Mercuri — GoldiMercuri
- Exact Adex ID: `GoldiMercuri`; canonical record: https://adex.page/firms/GoldiMercuri .
- Research date and source access date: **2026-10-06**.
- Status: **complete research**, with limitations below; research only, no Adex/database changes.
Mercuri is the London media technology and AI venture investor founded in 2017 as GMG Ventures. Its current mandate is UK pre-seed and seed, typically the first institutional cheque; its latest-known announced fund is Fund II, £50 million in 2023. Literal Labs provides a particularly clear research-based deep-tech investment; other verified portfolio exposure includes AI infrastructure, applied AI and generative audio. No verified neurotech investment found in the sources checked. [Official firm](https://www.mercuri.vc/ ), [official strategy](https://www.mercuri.vc/approach ), [British Business Bank, 2023-07-04](https://www.british-business-bank.co.uk/news-and-events/news/gmg-ventures-rebrands-to-mercuri-and-closes-a-50m-fund ).
## Starting evidence: Adex and NFX Signal
The saved exact-ID Adex MCP snapshot `_sources/GoldiMercuri.adex.json`, retrieved 2026-10-06, identifies Mercuri (formerly GMG Ventures), London, certified B Corp, with official URL https://www.mercuri.vc/ and Signal URL https://signal.nfx.com/firms/mercuri . It leaves check minimum/maximum and sweet spot null. Its team includes Alan Hudson, Esha Vatsa, Ella Harrison, Anna Jones and Denise Xifara, among others; titles should be reviewed separately rather than assumed current. Baseline investments include Electric Twin, Mozart/Mozart AI, Literal Labs, Signal/Signal AI, Minitap, Human Native, ittybit and Topship. Multiple overlapping company and round records need reconciliation. Snapshot sources include Goldi pages and press/firm posts; snapshot presence alone is not verification.
[Signal firm page](https://signal.nfx.com/firms/mercuri ) was directly read: it exposes the name and founding year 2017, but no populated team rows or cheque data in the extracted page. [Esha Vatsa's profile](https://signal.nfx.com/investors/esha-vatsa ) was directly opened and also search-index readable: Partner at Mercuri GP LLP, claimed $1.5m–$3.3m range/$2.5m sweet spot, and Literal Labs pre-seed June 2025, alongside Kamma and Vauban. These personal histories do **not** establish Mercuri attribution for Kamma or Vauban; prior-firm and personal investing must remain separate. [Ella Hughes profile](https://signal.nfx.com/investors/ella-hughes ), search-index readable, claims associate status, £50m current fund and the same range. The Ella Hughes/Ella Harrison naming discrepancy is unresolved. [Anna Jones profile](https://signal.nfx.com/investors/anna-jones ), search-index readable, identifies an investment committee chair and pre-seed/seed media focus; investment details require sign-in. All are undated, accessed 2026-10-06, and are discovery evidence rather than authoritative current records.
## Fund size and stages
| Vehicle / metric | Amount and status | Date and supporting evidence |
|---|---|---|
| Fund I, originally GMG Ventures | **£42m** committed fund; Scott Trust sole investor according to LP reporting. This is a fund amount, not a cheque. | Firm founded 2017; precise fund close date not verified. [Scott Trust Endowment 2024 report](https://uploads.guim.co.uk/2024/09/17/The_Scott_Trust_Endowment_Ltd_report_2024.pdf ), published September 2024, calls the fund six years into its ten-year term and confirms the commitment. |
| Fund II / Mercuri II LP | **£50m raised/closed**, not merely a target; institutional LPs, British Business Bank cornerstone through Enterprise Capital Funds, with Scott Trust continuing as LP. | Official website says launched May 2023; [British Business Bank announcement](https://www.british-business-bank.co.uk/news-and-events/news/gmg-ventures-rebrands-to-mercuri-and-closes-a-50m-fund ), **2023-07-04**, confirms second fund raised. May launch and July announcement are different dates, not necessarily conflicting. |
| AUM | Official website reports **£92m AUM**; distinguish this self-reported aggregate from the £50m current vehicle and from available dry powder. | [Firm homepage](https://www.mercuri.vc/ ), undated, accessed 2026-10-06. |
| Initial cheque strategy | **£500k–£1m target**; 40% fund reserved for follow-ons; 6–8 new investments per year. | [Official approach](https://www.mercuri.vc/approach ), undated, accessed 2026-10-06. |
Fund II is the **latest-known publicly announced fund in the sources checked**. Searches for 2025/2026 newer funds and Fund III did not identify a verified subsequent close. [Companies House Mercuri II LP](https://find-and-update.company-information.service.gov.uk/company/LP023080 ) records registration on 2023-02-21 and former name GMG Ventures II LP through 2023-09-19; it does not establish fundraising size or remaining capital (undated current registry, accessed 2026-10-06).
Current stage evidence explicitly supports **pre-seed and seed**, leading rounds in UK media, entertainment and AI companies, with later follow-on financing. Historical late-stage portfolio participation should not broaden the new-investment mandate automatically. [Official approach](https://www.mercuri.vc/approach ). The 2023 LP announcement described leading seed rounds, while the current official strategy explicitly includes pre-seed. The current official GBP cheque target conflicts with Signal's substantially larger USD range; use official current strategy as stronger evidence and retain Signal values only as a dated comparison, not hard bounds.
## Named previous deep-tech investments
Classification below is research judgment about the underlying technology, not a claim that every media/AI portfolio business qualifies as deep tech. Funding amounts are **whole-round totals**, never Mercuri's own contribution unless explicitly stated.
| Company | Verified attribution / financing | Technology rationale and caveats | Supporting URL and date |
|---|---|---|---|
| **Literal Labs** | Mercuri **co-led** £4.6m (company reports $6.2m equivalent) **pre-seed**, with Northern Gritstone lead and other backers. | Newcastle University-linked logic-based AI algorithms, Tsetlin-machine research and efficient/explainable alternatives to neural networks. Clear algorithmic research commercialization; performance superiority is company-claimed, not independently validated here. | [Investee funding announcement](https://www.literal-labs.ai/news/literal-labs-funding.html ), release dateline **2025-05-28**, page updated **2025-06-02**; [investee research/team/supporters](https://www.literal-labs.ai/about/ ), undated. |
| **Faculty AI** | Mercuri says it first invested in the **2019 seed** under the GMG Ventures continuity. Exact round amount and firm cheque not verified. | Applied ML, responsible AI and decision intelligence platform; combines software and consultancy, so distinguish R&D-intensive platform capabilities from ordinary services revenue. | [Official Mercuri Faculty retrospective](https://www.mercuri.vc/blog/faculty-ai ), displays **15 January**, text explicitly places the retrospective/acquisition in **2026**. |
| **Hugging Face** | Official Mercuri homepage explicitly names it as an investment. Exact entry round, date and vehicle allocation were not verified. | ML model/dataset infrastructure and open-source AI tooling; credible advanced AI ecosystem exposure, but infrastructure/community platform does not by itself imply a new scientific breakthrough. | [Mercuri official homepage](https://www.mercuri.vc/ ); [investee official site](https://huggingface.co/ ), both undated. |
| **Fluidstack** | Official Mercuri homepage explicitly names the investment. Historical entry date/round and direct-versus-intermediated vehicle allocation were not independently established. | AI cloud/GPU compute infrastructure: relevant enabling infrastructure, not evidence of Mercuri financing novel semiconductor development. | [Mercuri official homepage](https://www.mercuri.vc/ ); [Fluidstack official site](https://fluidstack.io/ ), both undated. | SHOW MORE
