We know the systems from within
You do not receive an abstract risk assessment, but the judgement of someone who has been responsible for control and screening systems themselves — and who knows what can actually be implemented in your organisation.
00About HI
HÜNERMANN IKEN is a law boutique based in Frankfurt am Main, specialised in compliance, crisis management and regulatory special situations. We advise and represent national and international companies, financial institutions and their management and supervisory bodies.
Our work combines forensic experience from decades of international large-firm practice with operational knowledge of complex financial and group structures from an in-house leadership perspective. Every mandate is led by us personally. You therefore benefit directly from the partners' expertise.

01Why HI
You do not receive an abstract risk assessment, but the judgement of someone who has been responsible for control and screening systems themselves — and who knows what can actually be implemented in your organisation.
Reliable connections to regulators, investigating authorities and auditors help you precisely when speed matters and formal channels take too long.
As a specialised boutique we are not bound by the conflict positions of large international organisations. We can act for you where others have to decline.
No leverage model, no delegation to inexperienced associates. Whoever instructs us works with the partners — in strategy as well as in meetings with the authorities.
02Your team
HÜNERMANN IKEN is a highly specialised boutique, led and operationally run by the name partners personally. We work without a leverage model: strategy, crisis team and meetings with authorities rest with the partners themselves. You therefore draw directly on their experience.

Financial crime · Anti-money laundering · Sanctions · KYC and KYB · RegTech
When supervisors or investigating authorities raise questions on anti-money laundering, Dr Jan-Gerrit Iken knows the answer from both perspectives: that of the adviser and that of the officer in charge. He is among the most prominent experts in Europe for financial crime, anti-money laundering and sanctions.
He was Global Head of Monitoring & Screening and Deputy Group AML Officer at Deutsche Bank, and Deputy Chief Compliance Officer and Global Head of Financial Crime at Commerzbank. As Head of Group Compliance, Security & Forensics he led crisis and restructuring situations at international institutions, including Hypo Alpe Adria. Through innovation platforms he advances the use of legal and RegTech in order to meet KYC and KYB requirements in a scalable and legally sound manner. He is a co-founder of AFCA Germany, the public-private alliance against financial crime in Germany.
03Our expertise
Open the area that comes closest to your situation.
The first hours after a dawn raid, a cyber incident or a money laundering suspicion determine how expensive the matter becomes. We take control so that your management remains able to act — and so that nothing is said or handed over that may later be used against you.
You need to know what actually happened: robustly, discreetly and documented in a way that holds up before authorities. We establish the facts — and then represent them vis-à-vis prosecutors and supervisors.
Whether you should onboard, retain or exit a business partner depends on facts that are rarely in plain sight. We create the basis for that decision and structure contracts so that default, reputational and sanctions risks do not end up with you.
A monitor or special representative on site changes day-to-day operations for months. We know these proceedings both from operational implementation and from legal support, and set them up so that the requirements are met without paralysing your business.
You need a system that holds up under examination — not a rulebook that merely looks good. We build it, or bring your existing system to a standard that supervisors and auditors accept.
Two things stand between a regulatory requirement and what your staff actually do: an intelligible instruction and an organisation able to deliver it. We design both together with your business functions, not from a desk far away.
Requirements grow faster than your budget. That can only be resolved with technology that withstands scrutiny. We combine the legal requirement with knowledge of the systems meant to fulfil it — from our own operational responsibility in large groups.
After a supervisory finding, what counts is not a statement of intent but proof that the deficiency has truly been remedied. We have run such programmes ourselves in large institutions and lead them from root cause analysis to closure evidence.
You want to know what new requirements actually mean for your institution — not what the official journal says. We translate legislative projects into impact, effort and a roadmap you can defend at board level.
Sometimes you need a body outside the organisation: for reports that do not get through internally, for a confidential second opinion and for training that goes beyond slogans.
If a key function is vacant, we fill it ourselves on an interim basis — in the role, with authority to instruct and a duty to report, not advising from the outside.
04Clients
Our clients are under supervision, under time pressure or under observation — often all three at once. We work for companies and institutions as well as directly for management board members, managing directors and supervisory board members who bear personal responsibility.
Major banks, private banks, asset managers, payment service providers and fintechs that have to answer to BaFin, the ECB and the Bundesbank. Here we know not only the requirement, but also the examiner who assesses it.
National and global industrial and trading companies, automotive suppliers and consumer goods manufacturers with multi-layered governance and supply chain requirements — down to the vetting of individual business partners.
Members of management boards, executive managements and supervisory boards who bear their own liability risks and need an adviser who clearly distinguishes between corporate and personal interests.
05Network
Regulatory special situations can rarely be resolved by legal means alone. So that you do not have to coordinate several service providers, we cooperate in a structured way with technology providers and auditors.
Technology partner
A compliance platform with direct access to commercial and transparency registers worldwide. Legalian enables continuous monitoring of your client or customer portfolio across fragmented registers in all relevant jurisdictions, extensive sanctions lists and nested ownership chains, bundled in one portal with a transparent data basis — from the KYC engine through sanctions and PEP screening to enhanced due diligence and ongoing monitoring. legalian.io
Technology partner
AI-supported compliance for banks, audit and advisory firms as well as companies in the non-financial sector: IDD and EDD reports, KYC and sanctions screening in hours instead of weeks. For companies this is above all relevant in third-party compliance — when vetting suppliers, sales intermediaries, consultants and joint venture partners under the German Supply Chain Act, sanctions law and anti-corruption requirements. Its Deep Research Investigation Tool produces a business intelligence profile of the counterparty: ownership and control structures, beneficial owners, sanctions and PEP links, adverse media and proceedings, condensed into a risk-rated basis for decisions. regbyrd.com
Professional network
Reliable connections to national and international regulators and investigating authorities, to audit firms and forensic service providers, and to befriended law firms in the relevant jurisdictions.

07Contact
Every mandate begins with an initial, confidential and non-binding conversation — with the partners personally. In it we review the situation together with you, assess at short notice whether and how we can support you, and come back to you with an initial view on the way forward. An engagement is established only upon a separate written agreement.
