Werner von Guionneau is a German-born finance executive, best known as the longtime CEO of InfraRed Capital Partners, a major infrastructure and real estate investment manager based in London. His full legal name, as it appears in UK Companies House records, is Werner Marc Friedrich VON GUIONNEAU, born April 1957. No verified personal net worth figure has been published for him in any audited or official disclosure. Unlike Werner von Guionneau, Chef Amaury Guichon is a public-facing pastry chef, and his net worth is often discussed as a separate celebrity-finance topic Chef Amaury Guichon net worth. Readers who want a quick figure should note that no verified personal nika guilbault net worth number is available in audited or official disclosures. Based on his career trajectory, seniority at a significant asset management firm, and documented equity interests in corporate structures, a reasonable working estimate would place his personal net worth in the range of several million to low tens of millions of pounds sterling, though that range carries real uncertainty and should be treated as an informed approximation rather than a confirmed figure.
Werner von Guionneau Net Worth: Best Estimates and How to Verify
Who exactly is Werner von Guionneau?
If you searched this name expecting an entertainer, celebrity, or sports figure, you have the wrong person. Werner von Guionneau is a senior financial services professional. He spent the bulk of his career at what was originally the HSBC infrastructure investment arm, helping to grow it into an independent platform. When InfraRed Capital Partners spun out of HSBC in 2011 as a management-owned firm, he led the transition as CEO. He then led the process that resulted in InfraRed being acquired by Sun Life Financial in 2019, a transaction that would have had direct equity implications for senior management. In July 2023, he stepped back from the CEO role and moved into a newly created Chairman position, with Jack Paris succeeding him as CEO.
His educational background, per InfraRed's own published materials including the TRIG (The Renewables Infrastructure Group) team page, includes business administration and economics at the University of St. Gallen in Switzerland, and a research fellowship at Harvard Business School. UK Companies House records confirm his nationality as German and his country of residence as England. The same full name also appears in UK Charity Commission records as a trustee, and in blank" rel="noopener noreferrer">Singapore Exchange (SGX) regulatory filings in connection with a deemed interest disclosure relating to an entity called Famous Way Properties Limited. These are not the records of a private individual living under the radar: this is someone with a traceable, multi-jurisdictional corporate and regulatory footprint.
Watch out for name confusion
There is at least one other person with a similar surname in public records: a Nicholas von Guionneau appears in an unrelated research directory and has no connection to InfraRed or infrastructure finance. If you are researching wealth or career data and land on something that does not mention infrastructure investment, London, or InfraRed Capital Partners, double-check that you have the right individual. The full name Werner Marc Friedrich VON GUIONNEAU is the clearest identifier when searching official records.
What net worth actually means here, and what you can't know
Net worth is the total value of someone's assets minus their liabilities. For a private individual like Werner von Guionneau, that would include equity stakes in private companies, property holdings, investment portfolios, cash and cash equivalents, pension entitlements, and any other assets, minus mortgages, loans, and other obligations. The problem is that none of that is publicly disclosed for a private person who is not a listed company director required to publish a full remuneration report.
What does appear in public records are corporate-level net worth figures. For example, Companies House data aggregators like Companycheck.co.uk show a net worth of around £11 million for INFRARED CAPITAL PARTNERS (HOLDCO) LIMITED as of 2024. Companycheck’s Company House wrapper for INFRARED CAPITAL PARTNERS (HOLDCO) LIMITED reports “net worth” values for the corporate holding entity, which is derived from filed accounts rather than being an audited disclosure of Werner von Guionneau’s personal net worth Companies House data aggregators like Companycheck.. This is the net worth of the corporate holding entity, derived from filed accounts, not Werner von Guionneau's personal net worth. A separate entry for HSBC SPECIALIST INVESTMENTS LIMITED (a predecessor entity) shows a corporate net worth of around £60 million for a prior year, and HSBC PROPERTY FUNDS (HOLDING) LIMITED shows a negative net worth figure for 2020. These corporate-level metrics vary wildly and should never be directly equated with the personal wealth of any individual associated with those companies.
Best available net worth estimates and their confidence level
There is no celebrity net worth database entry for Werner von Guionneau, and no credible public source has published a specific personal net worth figure for him with documented methodology. What we can do is construct a reasoned estimate from career and financial signals.
| Basis for estimate | Indicative range | Confidence level |
|---|---|---|
| Seniority at InfraRed (CEO of a multi-billion AUM manager, 2011-2023) | £5M - £30M+ total compensation over career | Moderate: based on sector norms |
| Equity stake at InfraRed spin-out (2011) and Sun Life acquisition (2019) | Potentially £1M - £10M+ depending on stake size | Low-moderate: stake size not disclosed |
| SGX deemed interest in Famous Way Properties Limited | Unknown quantum: confirms asset interest | Low: regulatory filing confirms interest, not value |
| UK property holdings (inferred from residency and seniority) | Unknown: not in public record | Very low: speculative |
| Overall personal net worth estimate (aggregate) | £5M - £20M (working range) | Low: no audited source; reasoned estimate only |
The working estimate of £5 million to £20 million is calibrated against what senior partners and CEOs at comparable mid-sized alternative asset managers in London typically accumulate over a career of this length and seniority. It is not drawn from a single verified source, and it could be significantly higher or lower depending on factors that are not publicly knowable, including the actual size of his equity participation in the Sun Life transaction and the structure of any carried interest arrangements.
How wealth estimates like this are built
For a financial professional rather than a celebrity or public company executive, wealth estimation follows a different methodology than for, say, a listed CEO whose pay package is disclosed in an annual report. Here is how analysts and researchers typically approach it:
- Career compensation benchmarking: senior executives at alternative asset managers of comparable size (typically managing several billion in assets under management) earn base salaries of £300,000 to £700,000 and bonuses that can match or exceed base. Over a decade-plus career at that level, gross pre-tax earnings alone could reach eight figures.
- Equity event analysis: when InfraRed spun out from HSBC in 2011 as a management-owned platform, senior management would have received equity. When Sun Life acquired InfraRed in 2019, those equity holders would have crystallised gains. The size of those gains depends on the acquisition price and individual stakes, neither of which is publicly disclosed.
- Carried interest: infrastructure fund managers earn carried interest (a share of profits from fund performance), which can be the largest single wealth component for senior partners in this asset class.
- Property and other assets: UK Land Registry and Companies House records can reveal property ownership and corporate shareholdings, adding further data points.
- Liabilities offset: mortgages, any business-related debt, and other obligations reduce the gross asset figure to arrive at net worth.
The SGX Form 3 filing that references Werner Marc Friedrich Von Guionneau in connection with Famous Way Properties Limited is a concrete, regulatory-grade signal that he holds interests in investment entities beyond his employment at InfraRed. That kind of deemed interest disclosure, required under Singapore securities law, confirms real-world asset exposure but does not quantify its value.
Career and financial signals worth knowing
Three events in Werner von Guionneau's career are the most financially significant and most likely to have shaped his current wealth position. First, the 2011 spin-out of InfraRed from HSBC as a management-owned independent platform: this is the kind of transition where founding management teams receive meaningful equity, often structured as a management buyout or equivalent arrangement. Second, the 2019 acquisition of InfraRed by Sun Life Financial: institutional acquisitions of well-regarded alternative asset managers of InfraRed's scale typically involve purchase prices in the hundreds of millions of dollars range, and management equity holders receive proceeds at closing. Third, his transition to Chairman in July 2023 rather than departing entirely suggests a continued stake or economic interest in the business going forward.
On the corporate record side, his name appears as an officer across multiple Companies House-registered entities connected to InfraRed's corporate structure. He is also listed as a trustee in at least one UK registered charity (Charity Commission number 01191507), alongside Christopher Paul Gill. These are ancillary signals that confirm active institutional engagement but do not directly quantify personal wealth.
Why net worth estimates vary across websites, and how to judge them
If you find a net worth figure for Werner von Guionneau on a generic celebrity wealth aggregator, treat it with real skepticism. Most of those sites use one of three approaches: they copy figures from other aggregator sites without verification, they use corporate entity net worth figures from Companies House (as described above, which is a company figure, not a personal one), or they apply broad salary multipliers without any knowledge of the specific individual's equity events or investment history. None of these approaches is transparent about methodology, and none of them has access to private financial information.
A more credible approach, which this article attempts, is to identify verified career milestones, cross-reference regulatory filings across multiple jurisdictions (UK, Singapore in this case), benchmark against comparable industry compensation norms, and be explicit about what is and is not known. The honest answer is that for a private financial professional at Werner von Guionneau's level, precise net worth is simply not publicly knowable. What you can say with confidence is the approximate magnitude and the key value-creation events that shaped it.
For comparison, other financial and creative professionals profiled on this site face similar constraints. Figures like Bruno Lowagie or Gaspard Ulliel operate in entirely different fields (software and film respectively), but the same principle applies: the reliability of any net worth estimate depends entirely on how much of the underlying asset and income data is actually disclosed publicly. Bruno Lowagie net worth estimates are similarly constrained by what financial disclosures are actually available publicly. If you are also looking up Gaspard Ulliel net worth, the same rule applies: verify whether any figure is personal, or just a corporate/aggregator estimate.
How to research this further today
If you need to go deeper on Werner von Guionneau's financial profile, here is a practical checklist of the most useful public resources available as of June 2026:
- UK Companies House (find.companieshouse.gov.uk): search 'Werner Marc Friedrich VON GUIONNEAU' to pull his full officer appointment history, the companies he is or was associated with, and any filed accounts for those entities. This is the most authoritative UK corporate source.
- UK Land Registry: search for property ownership by name or company. This requires a paid search but gives you any registered UK property interests.
- SGX SGXNET regulatory filings: search for 'Von Guionneau' in the SGX announcements portal to find the Form 3 deemed interest disclosure and any related filings. These are free to access.
- UK Charity Commission (register of charities): search Charity number 01191507 or the name to confirm his trustee status and review any publicly available trustee disclosures.
- InfraRed Capital Partners official website and annual/investor materials: published investor day biographies and fund reports contain the most authoritative career information and are useful for corroborating identity and role history.
- Sun Life Financial investor materials (2019 onwards): the acquisition of InfraRed by Sun Life is referenced in Sun Life's own investor communications, which can provide context on the deal structure even if individual proceeds are not disclosed.
- OpenCorporates or equivalent: aggregates Companies House data and can help map the network of corporate entities associated with a named officer.
- Companies House accounts filings for InfraRed holding entities: the actual filed accounts (balance sheets and P&L statements) for entities like INFRARED CAPITAL PARTNERS (HOLDCO) LIMITED are available as PDFs from Companies House and give a clearer picture than third-party aggregator summaries.
One practical caution: do not rely on any single aggregator site that presents a specific net worth figure without explaining how it was derived. If the site does not reference specific filings, transactions, or benchmarking methodology, the number is likely fabricated or copied from another site that fabricated it. The research chain above gives you primary sources you can verify yourself.
What you can say with confidence
Werner von Guionneau is a real, identifiable, senior financial professional with a verifiable career record across UK, European, and Asian markets. His full legal name is Werner Marc Friedrich VON GUIONNEAU, he was born in April 1957, holds German nationality, and is resident in England. His wealth-generating career spans the HSBC infrastructure investment arm and then InfraRed Capital Partners as an independent firm, including two high-value corporate transitions (the 2011 spin-out and the 2019 Sun Life acquisition) that are the most likely sources of significant personal wealth. An estimated personal net worth in the range of £5 million to £20 million is a defensible working figure based on career benchmarking and known financial events, but it is not a verified number. If precision matters for your research, the public records listed above are your best tools, and you should expect to find corporate and regulatory data rather than personal financial disclosures.
FAQ
How can I tell if a claimed “Werner von Guionneau net worth” number is personal or just corporate?
Look for personal disclosure, not company accounts. For him, public filings tend to show roles (officer, trustee) or corporate entity figures, while a personal net worth typically requires direct disclosure of holdings or remuneration that is not present. If a website claims a single personal net worth number, check whether it cites audited personal disclosures or only repackages corporate net worth from Companies House aggregators.
Why do Companies House net worth figures for related InfraRed entities vary so much, and can I use them for his personal net worth?
Companies House “net worth” figures for entities can be negative or wildly different year to year because they are derived from balance sheet items in filed accounts, not from the market value of assets. Treat any corporate figure (for example holdco entities) as an upper bound for potential value exposure, not as proof of his personal wealth.
What should I do if search results show a Nicholas von Guionneau or another similarly named person?
Yes. Use the full legal name, Werner Marc Friedrich VON GUIONNEAU, and verify the same date of birth and residency signals when available. If you see a similarly named person in an unrelated directory or you do not find InfraRed-linked records, assume it is a different individual and stop using that result for wealth calculations.
Why are salary-multiplier net worth estimates especially unreliable for Werner von Guionneau?
Do not rely on multiplier methods (salary times years or generic partner income ratios) unless the source also explains the specific equity and liquidity events for this individual. In his case, the more decision-relevant items are equity-linked corporate transitions (2011 spin-out and 2019 acquisition) and any ongoing economic interest after moving to Chairman in 2023.
How do I evaluate whether a net worth website is fabricating or copying numbers?
If a site quotes an exact pound figure, check for transparency: it should explain whether it is (1) a corporate net worth proxy, (2) a copied aggregator number, or (3) a derived model tied to specific disclosed transactions or filings. If it provides no methodology or no references to filings and deals, treat the number as unverifiable.
What can SGX or other regulatory “deemed interest” disclosures tell me, and what can’t they tell me?
Use regulatory filings to confirm exposure, then convert cautiously. For example, SGX “deemed interest” style disclosures can confirm that he has interests in an entity, but they usually do not provide a valuation of those interests, so you still need assumptions to translate exposure into net worth.
Can I infer his personal wealth from being listed as an officer in Companies House entities or as a charity trustee?
Corporate and regulatory links alone generally cannot prove personal asset size. The practical reason is that many holdings are indirect (through entities or managed structures), and personal net worth depends on ownership percentages and when interests became liquid, details often not in public records.
Which career events should matter most for verifying or tightening a “Werner von Guionneau net worth” range?
Track which events plausibly produced liquidity, not just career milestones. For him, the most net-worth-relevant points to investigate are management-ownership equity in the 2011 spin-out, management proceeds or retained interests tied to the 2019 Sun Life acquisition, and whether Chairman status indicates continued economic interest.
