Risk scorecard
Each area is scored 0 (clean) to 10 (worst). Higher means more risk.
Regulation
10/10 · CriticalNo licence in any jurisdiction while opening client trading accounts, ten regulator names displayed without a single number, and a warning-list entry from the Finnish supervisor naming the exact address.
Identity & transparency
10/10 · CriticalThe operation wore two real companies' identities: a Helsinki advisory's name and registered address, and a Stockholm private equity firm's office address, founding year and headline figures.
Withdrawals & conduct
4/10 · ModerateNo fund-integrity or service complaints surfaced on any platform, but the operation left almost no public trace before its site went dark, so this is an absence of reports rather than evidence that clients were paid.
Reputation
8/10 · CriticalThe only substantive third-party record of this address is a national regulator listing it as a suspected fraud and a clone. There is no positive footprint of any kind to weigh against it.
Website claims
10/10 · CriticalClaimed approval as a French credit institution and an AMF investment services provider that the French register does not show, declared share capital of 14.7 billion euros, and advertised a founding year six years before the domain existed.
Operational history
9/10 · CriticalFirst evidence of the domain is April 2022 and the last captured page is April 2023, so under a year of operation against an advertised history going back to 2016, with no predecessor domain.
Who they are
A quick desk file on the company behind the brand.
- Brand: Summa Capital, trading as Summa Capital OY
- Legal entity: none of its own could be established. The name it used belongs to another company
- Registered: nowhere. No company registration, licence or authorisation of its own exists in any jurisdiction we checked
- Website: summa-capitaloy.com, which no longer resolves. A client portal ran at client.summa-capitaloy.com
- Only licence: none. The home page showed ten European and Gulf regulator names under the heading Nos regulations, with no licence number against any of them
- Offers: forex, share and index CFDs, commodities and crypto, sold in French through its own account-opening funnel and login area
- Not accepted: no restricted-country list was published, while the whole site was written for French speakers
- Age claim: Etablie 2016 on the home page. The domain first appears in April 2022

Why we reached this verdict
How the evidence adds up.
Two findings settle this independently, and neither depends on user complaints.
- A regulator named the exact address. The FIN-FSA warning list of unauthorised service providers carries an entry dated 18 November 2022 for https://www.summa-capitaloy.com/, marked CLONE, with the description that the authority has cause to suspect the company is a fraud and that it misuses the Finnish company's information incorrectly. The entry is still published.
- The identity belongs to someone else. The Finnish Trade Register records the name Summa Capital Oy and business number 2078965-1 against a Helsinki corporate finance advisory registered in December 2006, whose registered website is www.summa.fi. That firm advises companies on mergers and acquisitions. It does not run a retail trading platform.
The rest of the picture is consistent with that, and it is unusually blatant.
- The Helsinki office the site published, Pohjoinen Makasiinikatu 4, is the advisory firm's own address. The Stockholm office it published, Birger Jarlsgatan 27, 11145 Stockholm, is the registered office of Summa Equity AB, a separate Nordic private equity firm, matching down to the postcode.
- The home page carried Summa Equity's positioning almost word for word, including the line about investing to solve global challenges, the founding year 2016, and a statistics block of three funds, 275 employees, 381 portfolio companies and roughly 40 billion Swedish kronor of assets. The company page then switched to the Helsinki advisory's numbers: 47 M and A transactions and 5 billion euros of transaction value.
- The terms page claimed the operation was a French credit institution approved by the prudential supervisor and an investment services provider approved by the Autorite des Marches Financiers. It gave Swiss street addresses for both French authorities and declared share capital of 14,740,660,514 euros. A search of REGAFI, the French register of banking, payment and investment firms, returns no result for Summa.
- No licence number appeared anywhere on the site, for any of the ten authorities whose names it displayed.
- The claimed founding year of 2016 predates the first evidence of the domain by about six years. The earliest certificate issued for summa-capitaloy.com is dated 27 April 2022, and the earliest capture of the site is from July 2022. There is no predecessor domain carrying earlier history.
We assess the risk of fraud as very high. The site opened client accounts and offered leveraged trading while holding no permission to do so anywhere, using two real companies' names and addresses to look established.
One limit on the record is worth stating plainly: no client has publicly described losing money here. There is no Trustpilot page for the domain and no complaint threads under it. That is an absence of reports rather than proof that money came back, and it fits an operation that ran for well under a year before it went dark.
Scoring: the six scored dimensions give a weighted mean of 9.0 out of 10, which sets the base at 90 percent. Two independent hard findings, the regulator warning and the confirmed use of another company's identity, hold the floor at 90. We publish 93 because the regulator's own entry classifies the site as a clone rather than merely unauthorised.
Note on operating history: the 4.4-year track record rests on domain registration alone. No company incorporation date could be established, so this is an upper bound rather than a confirmed age.
Evidence ledger
Every finding, with its source and how strongly it points.
E1The Finnish Financial Supervisory Authority's warning list of unauthorised service providers carries an entry dated 18 November 2022 for https://www.summa-capitaloy.com/, marked CLONE, describing that the FIN-FSA has cause to suspect the company is a fraud and that it misuses the Finnish company's information incorrectly.
E2The Finnish Trade Register records the name Summa Capital Oy and business ID 2078965-1 against a company registered on 5 December 2006, previously named Summa Corporate Finance Oy, whose registered website is www.summa.fi and whose activity is auxiliary financial services. That is a different operation from the trading site, which never appears against this record.
E3The site's own contact page listed three offices: Stockholm at Birger Jarlsgatan 27, 11145 Stockholm; Munich at Ludwigstrasse 9, 80539 Munich; and Helsinki at Pohjoinen Makasiinikatu 4, 00130 Helsinki, which is the Helsinki advisory firm's own address.
E4Summa Equity AB publishes Birger Jarlsgatan 27, 11145 Stockholm as its own visiting and postal address, matching the trading site's published Stockholm office exactly, including the postcode. Summa Equity also runs a Munich office, mirroring the office pattern the trading site advertised.
E5The site's terms stated that Summa Capital is a French credit institution approved and controlled by the prudential supervisor, and an investment service provider approved and controlled by the Autorite des Marches Financiers, giving Swiss street addresses in Geneva and Wollerau for those two French authorities, and declaring share capital of 14,740,660,514 euros.
E6REGAFI, the French register of banking, payment and investment firms maintained by the prudential supervisor and last updated 11 September 2026, returns no result for a search on Summa across both the banking and insurance registers. No entity of that name holds French authorisation.
E7The home page carried a row headed Nos regulations, naming Finansinspektionen, the FSMA, the AFM, CONSOB, REGAFI, Finanstilsynet, the CNMV, BaFin, the FCA and the DFSA, with an invitation to secure your investments using these regulations. No licence number was given for any of them, on that page or anywhere else on the site.
E8The home page advertised Etablie 2016 alongside a statistics block of three funds, 275 employees, 381 portfolio companies, roughly 40 billion Swedish kronor of assets and a thematic strategy, which is the profile of the Stockholm private equity firm rather than of a trading platform. The company page then used the Helsinki advisory's figures of 47 M and A transactions and 5 billion euros of transaction value.
E9Certificate transparency records show the first certificate issued for summa-capitaloy.com on 27 April 2022 and the last on 14 March 2023, with no other names on any of the twelve certificates. That places the domain's first appearance about six years after the founding year the site advertised.
E10The site sold retail trading, not advisory services: an account opening page, a platform page with log in and sign up, and an instruments page covering indices, large-cap US shares, the metaverse, commodities, forex and cryptocurrencies, all written in French. A separate client portal ran at client.summa-capitaloy.com and webmail at mail.summa-capitaloy.com. This rules out the exemptions that apply to prop firms and introducers.
E11The genuine Summa Capital in Helsinki is a corporate finance advisory founded in 2003 that has completed 47 M and A transactions worth over 5 billion euros and serves listed companies, private companies, private equity and institutional investors. It sells no retail forex, CFD or crypto products.
E12The AMF list of unauthorised operators, checked across the alphabetical listing, carries no entry for this brand or address. Absence from a warning list is not clearance, and it is recorded here only so the sweep is auditable.
E13No review profile exists for the domain on Trustpilot, and searches across review platforms, forex forums, discussion sites and French-language consumer reporting turned up no first-hand account naming this address, positive or negative.
E14summa-capitaloy.com no longer resolves. Archive coverage of the site runs from 21 July 2022 to 7 April 2023 across the home page, company, instruments, platform, registration, contact, privacy and terms pages, after which nothing further was served.
The other side
The strongest case in this broker’s favour.
Before reaching this verdict we tested the innocent explanations. None survived.
- Could it be a regional arm of the real Summa Capital? No. The Finnish Trade Register records summa.fi as that company's website, and the advisory's own site describes an institutional M and A practice with no retail trading. The FIN-FSA, which supervises Finland's financial market, describes the site as a clone misusing a Finnish company's information.
- Could it be connected to Summa Equity? No. Summa Equity AB publishes Birger Jarlsgatan 27 as its own Stockholm office and lists its offices in Sweden, Norway and Germany. It sells fund interests to institutions, not CFDs to the public.
- Could the warning be about a different firm with a similar name? No. The FIN-FSA entry names the full web address, not the brand, so there is no room for a name collision.
- Could a licence simply have been too new to appear? No. The site named ten authorities and produced not one licence number, and the French register it specifically invoked returns nothing for Summa.
- Is it a prop firm or an introducer, which would need no licence? No. It ran its own account opening page, its own login area at a client subdomain, and marketed forex, indices, shares, commodities and crypto trading directly.
In fairness to the operation, the following should be recorded. No regulator has published an enforcement decision or a court judgment against it or any named individual behind it. No victim account naming this address has surfaced on any review site or forum. The Autorite des Marches Financiers blacklist, which is the list most likely to cover a French-language site, carries no entry for it. And it appears to have been short-lived rather than long-running.
What would change this
What we would need to see to revise the verdict.
This verdict rests on records that can be rechecked. Any of the following would force us to revise it.
- The FIN-FSA removing the 18 November 2022 entry, or stating that the listing was made in error.
- Summa Capital Oy of Helsinki or Summa Equity AB confirming that summa-capitaloy.com was an authorised channel of theirs, and the Finnish Trade Register showing the connection.
- A register entry at any named authority showing a licence genuinely held by the operation behind that address, with the address recorded against it.
- REGAFI showing an ACPR or AMF authorisation matching the entity named in the site's terms.
- Documentary evidence that the Helsinki and Stockholm addresses were used with the permission of the companies that occupy them.
If the brand reappears on a new address, none of the above transfers to it. A new domain would be assessed on its own records.

Frequently asked questions
Quick answers about this broker’s safety.
Is Summa Capital at summa-capitaloy.com a scam?
Yes. Finland's Financial Supervisory Authority listed the address https://www.summa-capitaloy.com/ on 18 November 2022 and tagged it CLONE, stating it has cause to suspect the company is a fraud and that it misuses a Finnish company's information. The site used the name, business identity and Helsinki address of an unconnected advisory firm, and held no licence anywhere.
Is Summa Capital a fraud?
The Finnish regulator says it has cause to suspect the company behind summa-capitaloy.com is a fraud, and that is the finding we rely on rather than a label of our own. Separately, we found the site presenting another company's name and addresses as its own and claiming French authorisation it never held. We assess the risk of fraud as very high.
Is this the same as the real Summa Capital in Helsinki?
No, and the distinction matters. The genuine Summa Capital Oy is a partner-owned corporate finance advisory in Helsinki, founded in 2003, registered in the Finnish Trade Register under business ID 2078965-1, with its website at summa.fi. It advises companies on mergers, acquisitions and financing. It does not offer retail trading accounts and has no connection to summa-capitaloy.com.
What about Summa Equity? The site mentioned Stockholm.
Summa Equity AB is a real Nordic private equity firm with its office at Birger Jarlsgatan 27, 11145 Stockholm, which is the exact address the trading site published as its own. The site also reproduced Summa Equity's founding year of 2016 and its headline fund figures. Summa Equity had nothing to do with the trading site.
Was Summa Capital regulated?
No. It displayed ten regulator names on its home page, including the FCA, BaFin, CONSOB, CNMV, the AFM, the Belgian FSMA, Finansinspektionen, Finanstilsynet, the DFSA and REGAFI, without a single licence number. Its terms went further and claimed approval as a French credit institution and as an AMF investment services provider. REGAFI, the French register, holds no Summa entity at all.
Can I still access my account or withdraw money?
No. The domain no longer resolves and has served no page since April 2023, so the client portal is gone. If you have money with this operation, treat it as a loss to be pursued through your bank rather than through the platform, and act quickly.
I deposited money. What should I do now?
Contact your bank or card issuer today and ask about a chargeback or a payment recall, because the time limits are short. Then report it to your national financial regulator and to the police, keeping every transfer receipt, email and chat log. If you paid in cryptocurrency, give the receiving wallet addresses to the police as well.
Someone has offered to recover my money for a fee. Should I pay?
No. Charging an up-front fee to recover funds lost to a trading scam is itself a standard follow-up scam, and lists of earlier victims circulate among the people running them. Genuine regulators and police never ask for a payment to release or recover your money.
How old was this operation?
Much younger than it claimed. The home page said Etablie 2016, borrowing a real private equity firm's founding year. The earliest certificate issued for the domain is dated 27 April 2022 and the first captures of the site are from July 2022, with the last from April 2023. On the evidence, it ran for under a year.
Were there customer complaints about it?
We found none, and we found no positive reviews either. There is no Trustpilot page for the domain and no complaint threads naming it on forex forums or discussion sites. That is not reassurance. It reflects a short-lived operation that a regulator flagged within months, and an absence of reports is not evidence that clients were paid.
Did any other regulator warn about it?
The Finnish FIN-FSA entry is the one that names the address directly. The AMF list of unauthorised operators in France, which is the list most likely to cover a French-language site, carries no entry for it. A clean sweep elsewhere does not offset a warning that names the exact address, since warning lists reflect what each authority has looked at.
What should I check before depositing with any broker?
Find the licence number on the broker's own pages, then search it on the regulator's public register yourself and confirm the register shows the same company name and the same website. Check the company registration in its home country. A row of regulator logos with no numbers behind them, as on this site, means nothing at all.
What we recommend
The practical takeaway from everything above.
Treat any site trading under this name and address as unsafe.
- Send it no money, and give it no identity documents, card details or remote access to your device.
- If you already deposited, contact your bank or card issuer immediately and ask about a chargeback or payment recall. Speed matters more than anything else here.
- Report it to your national financial regulator and to the police. In Finland the FIN-FSA takes reports of suspected unauthorised providers, and in France the AMF and the ACPR do.
- Ignore anyone who contacts you offering to recover your funds for a fee paid up front. Follow-up approaches to people who have already lost money are common, and they are a second scam.
- Do not confuse this with the genuine firms. Summa Capital Oy in Helsinki, at summa.fi, is a corporate finance advisory, and Summa Equity AB in Stockholm is a private equity firm. Neither sells trading accounts to the public, and neither has any connection to the site described here.
- If the same branding turns up on a different address, treat it as the same risk until a regulator's register says otherwise.
