As of June 2026, no widely trusted source has published a verified, methodology-backed net worth figure for James Rasteh. What public records do confirm is that he is the founder, sole owner, and CIO of Coast Capital, an SEC-registered activist hedge fund managing approximately $103 million in regulatory assets under management (AUM) as of its March 31, 2026 Form ADV filing. Based on standard hedge-fund economics (management fees, carried interest, and GP ownership rights), a reasonable working estimate for his personal net worth falls in the range of $10 million to $50 million, but that range carries meaningful uncertainty and should be treated as an informed proxy rather than a confirmed figure.
James Rasteh Net Worth: Estimate, Sources, and How It’s Calculated

Which James Rasteh are we talking about?
The James Rasteh behind most financial searches is Amir James Rasteh, born June 1975. He is the founder and Chief Investment Officer of Coast Capital, an activist investment firm that has taken public positions in companies like FirstGroup plc and Vodafone. He is not a celebrity, entertainer, or athlete, which is why general celebrity net-worth databases tend to either miss him entirely or serve up mismatched results for unrelated people named James.
His identity is anchored across several authoritative public records. The SEC's Form ADV for CRD 289883 lists "RASTEH, AMIR, JAMES" as an associated person and names him as the sole member of Coast Capital Management GP, LLC. GOV.UK Companies House lists "Mr Amir James Rasteh" as a Person with Significant Control (PSC) of Coast Capital Management Ltd, with ownership and voting rights of 75% or more, and a listed country of residence of the Cayman Islands. Bloomberg and The Deal have both quoted him directly as "founding partner" and "founder of Coast Capital LLC" respectively. That combination of SEC filings, UK company records, and credible financial media makes the identity match very solid.
If you landed here looking for a different James Rasteh, such as an actor, author, or other public figure, this article is not about that person. You might also find it useful to compare notes with profiles of other R-named professionals on this site, including James Ransone, James Rallison, James Raisbeck, James Renner, and James Edward Alexander Rundell Guinness, who represent a wide range of industries and wealth profiles. If you are comparing those outcomes, you can also review the James Edward Alexander Rundell Guinness net worth perspective for context on how different wealth pathways show up in estimates.
Current estimated net worth snapshot
With no verified personal balance sheet available, the most defensible approach is to frame his net worth as a range derived from what we do know. Coast Capital's latest ADV filing (March 31, 2026) reports $103 million in regulatory AUM. As the sole owner and GP of the fund structure, Rasteh would typically earn a management fee (commonly around 1.5% to 2% of AUM annually, so roughly $1.5 million to $2 million per year in fee revenue before expenses) plus carried interest on profits (typically 20% of gains above a hurdle rate). Over the course of a multi-year fund with activist positions in publicly traded companies, accumulated carried interest and retained earnings could meaningfully exceed annual fee income.
Taking those economics into account, alongside the likelihood that a founder-CIO running an activist hedge fund for over a decade has accumulated personal investments, co-investment stakes, and retained earnings, a working estimate of $10 million to $50 million is reasonable. The lower end reflects a scenario where fund performance has been modest and most capital is tied up in illiquid positions. The upper end reflects stronger carry realizations and personal investment compounding. Until there is a liquidity event, a public disclosure, or a credible investigative report with sourced methodology, the true figure remains private.
How net worth is actually calculated for someone like this
Net worth is assets minus liabilities, but for a private hedge-fund manager, almost none of those inputs are directly observable. Here is how estimators (including this one) typically build the picture:
- GP economics: As sole member of the GP entity, Rasteh has governance and economic rights over the fund's profit allocations. Carried interest accrues as the fund generates returns above its hurdle rate. This is often the largest wealth driver for successful fund managers.
- Management fees: Charged annually on AUM, these cover operating costs and provide base income. At $103M AUM and a 1.5% to 2% fee rate, annual gross fee revenue would be in the $1.5M to $2M range before firm expenses.
- Co-investment and personal stakes: Founders often invest their own capital alongside the fund. Any personal stake in positions like FirstGroup or Vodafone would have its own mark-to-market value.
- Accumulated retained earnings: Over years of operations, net income not reinvested in the business builds personal wealth.
- Liabilities: These include any personal guarantees, legal judgments, or debt. A court decision referencing "James Rasteh" (in Jain v. Rasteh) has surfaced in public records, but its connection to Amir James Rasteh of Coast Capital has not been independently confirmed and should be verified before being factored in.
His career and how the money is made
James Rasteh built Coast Capital as a value and event-driven activist fund with a particular focus on mining and undervalued public companies. His public profile as an activist investor means his strategy involves taking meaningful stakes in companies, pushing for operational or governance changes, and exiting when value is realized. Bloomberg reported on Coast Capital selling its Vodafone stake in January 2023 after holding it for under a year, illustrating the kind of concentrated, active-exit approach that can generate significant realized gains when timed well.
He has been outspoken in public forums, including a Real Vision interview where he appeared as "partner and CIO" to discuss gold miners, and a widely circulated piece (republished by Inkl from Insider UK) where he criticized FirstGroup's board over what he called value destruction. That kind of public activism is typically designed to catalyze share-price movement, which benefits fund performance and, in turn, carried interest distributions to the GP.
His income profile looks like this: base management fees provide a recurring revenue floor, event-driven gains from activist campaigns (when they succeed) generate carry, and any personal co-investments add direct upside. This is structurally different from, say, a salaried executive or a celebrity with endorsement income, which is why standard net-worth databases struggle to model it accurately.
Why estimates vary so much depending on where you look
If you have searched "James Rasteh net worth" and landed on multiple sites with wildly different numbers (or numbers that do not seem to be about him at all), there are a few reasons for that. First, celebrity net-worth aggregators often scrape and republish data without verifying which James they are describing. It is entirely possible that a result you see is actually about a different James entirely, a misattributed actor, musician, or other public figure whose name is close enough to trigger a match in their database.
Second, even sites that correctly identify Amir James Rasteh face the fundamental problem that he is a private individual managing a private fund. There is no public equity stake to value (unlike a founder of a listed company), no disclosed salary, and no mandatory financial disclosure beyond what SEC Form ADV and Companies House filings require. Coast Capital’s SEC-filed Form ADV Part 2A brochure also identifies James Rasteh as the firm’s Chief Compliance Officer (CCO) contact and describes him as the sole member of Coast Capital Management GP, LLC, linking him to the adviser’s regulated structure. So any number you see is a model output, not a reported figure. The quality of that model varies enormously across sources, and few of them publish their methodology.
Third, timestamps matter. AUM can change quarter to quarter, fund performance is not public, and carry is only realized when positions are exited. A number published in 2022 could be significantly off in either direction by mid-2026.
How to verify and update the number yourself
The most reliable public sources for tracking James Rasteh's financial profile over time are not net-worth sites. For the closest match to James Renner net worth-style estimates, rely on the same regulatory filings and business registries rather than generic databases net-worth sites. They are the same regulatory filings and business registries used to confirm his identity in the first place. Here is a practical workflow:
- Pull the latest SEC Form ADV for CRD 289883 at adviserinfo.sec.gov. The most recent filing is dated March 31, 2026 (reporting $103M AUM). Any amendment filed after June 26, 2026 will give you updated AUM, firm structure changes, and associated persons. AUM growth is a direct proxy for income-generation capacity.
- Check GOV.UK Companies House for Coast Capital Management Ltd. The PSC record confirms Rasteh's ownership and voting rights, and any changes to his control percentage would signal a material shift in his economic stake.
- Search PACER (federal court dockets) and state court databases for 'James Rasteh' and 'Amir J. Rasteh' to surface any litigation, judgments, or legal proceedings that could affect personal net worth through liabilities or settlements.
- Monitor financial media (Bloomberg, The Deal, Financial Times) for new activist campaigns or exits by Coast Capital. Announced position disclosures (especially 13D filings on SEC EDGAR) show what the fund holds, which gives you clues about personal co-investment exposure.
- For the UK entity, check Companies House filings annually (typically around the company's confirmation statement due date) for any changes in ownership structure, share classes, or new PSCs that might signal equity restructuring.
- Treat any net-worth figure you find on aggregator sites as a starting hypothesis, not a conclusion. Cross-check it against the AUM and fee economics described above, and note the publication date, because a stale estimate from 2022 or 2023 may not reflect current reality.
A quick comparison of what we know vs. what we are estimating
| Data Point | Source Type | Reliability |
|---|---|---|
| Identity: Amir James Rasteh, founder of Coast Capital | SEC Form ADV, Companies House PSC, Bloomberg, The Deal | High |
| AUM: ~$103M as of March 31, 2026 | SEC Form ADV (CRD 289883) | High |
| GP sole ownership of Coast Capital Management GP, LLC | SEC Form ADV Part 2A brochure | High |
| 75%+ ownership/voting rights in UK entity | GOV.UK Companies House PSC record | High |
| Estimated annual management fee income ($1.5M-$2M gross) | Derived from AUM x standard fee rate (1.5%-2%) | Medium (proxy) |
| Estimated personal net worth ($10M-$50M) | Modeled from GP economics, career tenure, and AUM scale | Low to Medium (no direct disclosure) |
| Court record referencing 'James Rasteh' (Jain v. Rasteh) | Leagle decision page | Unconfirmed (identity match not verified) |
The honest takeaway here is that the verified facts are strong on identity and role, but weak on personal balance sheet specifics. That is true for almost every private fund manager who has not taken their firm public or been subject to a major legal or regulatory disclosure event. The $10M to $50M range is a defensible working estimate as of June 2026, but anyone citing a precise figure for James Rasteh's net worth without referencing a methodology and a primary source should be treated with skepticism. If you still want a single-number takeaway, this is the most defensible way to interpret estimates of James Rallison net worth without overstating certainty $10M to $50M range.
FAQ
Why do some websites give a “James Rasteh net worth” number that seems wildly different from the $10M to $50M range?
Most sites are using scraped or guessed inputs, not a verified balance-sheet view. For a private hedge-fund GP, you cannot directly observe his equity stake value, carry accruals, or how much is tied up in illiquid positions, so different models will produce very different outputs (and some may even match the wrong person with a similar name).
If Coast Capital manages about $103 million in regulatory AUM, can I multiply that by a typical fee rate to get his net worth?
Not directly. Management fees are an operating income stream and they do not equal net worth because they must be reduced by fund expenses, taxes, and reinvestment, and because carry depends on realized performance over time. A more accurate approach is to model earnings persistence and realized carry, then compare it to what could reasonably be retained as liquid and private investment assets.
How does carried interest affect net-worth estimates for James Rasteh?
Carry can be the biggest driver, but it is only realized when profitable positions are exited and the GP meets the fund’s terms (including hurdle rates and clawback provisions, where applicable). That means someone can earn strong carry in a given year and still not show it as liquid wealth immediately if distributions lag or capital is reinvested.
Why is the range so uncertain even when SEC Form ADV and Companies House records are available?
Those filings are strong for identity, roles, and regulatory assets, but they are weak on personal financials. Form ADV generally does not disclose the GP’s personal balance sheet, co-investment book values, or how much he has already distributed versus retained, so estimates must infer private ownership rights and performance-driven retention.
What liquidity events would most likely change the estimated net worth number?
The biggest changes typically come from realized carry, partial or full exits of major positions, and any sale or recapitalization of the fund management entity or GP interest. Without those events being publicly quantified, estimates can swing but remain speculative.
If I find “Amir James Rasteh” listed with Cayman residence, does that mean his net worth is higher or lower?
Residence details do not determine wealth by themselves. Cayman country-of-residence can reflect fund structuring choices and compliance considerations, while personal net worth depends on long-run performance, reinvestment, and how much of earnings were converted into personal assets versus retained in the fund or used for expenses and taxes.
How can I confirm I am looking at the right person when searching “james rasteh net worth”?
Use the identity anchors described in the article, especially SEC Form ADV associated-person naming and Companies House PSC records tied to Coast Capital entities. If the page you find references a different industry (actor, athlete, author) or a different set of company names, treat it as likely misattributed.
What common mistake do people make when using net-worth sites for private fund managers?
They treat estimates as if they were reported figures. For private GPs, many “net worth” numbers are single-point guesses without disclosed assumptions about AUM timing, fee netting, carried-interest realization, tax effects, and the valuation of private holdings, so you should treat any exact number as non-verifiable unless it explains the methodology and inputs.
If I want a single takeaway number anyway, how should I interpret it responsibly?
If you need one number, use the midpoint of the working range as a rough heuristic, and remember that the true value could be materially different due to unrealized carry, valuation of illiquid stakes, and distribution timing. Avoid citing any precise value from a third-party site unless you can trace the calculation back to auditable inputs.
