Financial-crime compliance · Investigations
Fix your financial-crime programme. Then run it for less.
Arventis is a group of senior practitioners: former supervisors, money-laundering reporting officers, investigators and heads of compliance from banks, exchanges and trading firms. We help regulated firms repair programmes under pressure, find out what went wrong, and bring down the cost of compliance without weakening the controls.
When firms call us
Most of our work starts with one of four moments.
A regulatory finding
An exam finding, a consent order or an enforcement action. You need a plan your board can stand behind, delivered in a way examiners can test.
A backlog that won't shrink
Alerts, cases or customer reviews ageing past your service levels, and more arriving each week than the team can close.
Pressure from a partner bank
Your sponsor or correspondent bank wants to see stronger controls before its next review, and the date is fixed.
A new obligation
New anti-money-laundering rules are reaching firms that have never had to run a programme. It has to be built properly, the first time.
01 · Advisory
Four services, each scoped and priced before we start.
We don't sell a framework you have to fit into. We work from your risk, your customers and your systems, and we leave behind a programme your own team can run.
- Build
- A programme built from the ground up: risk assessment, policies, customer due diligence, suspicious-activity reporting, training and a test plan. Ready for its first exam.
- Firefight
- Backlogs cleared to a quality standard you sign off, with a sample checked by your own team. Then we fix the causes, so the queue doesn't come back.
- Remediate
- A remediation plan your board submits, then delivered and evidenced phase by phase until the finding is closed.
- Optimise
- A lower cost to run, with effectiveness tested before and after every change. A saving only counts if detection holds up and your own people have verified it. We cut waste, never coverage.
How an engagement starts
-
1
Scoping call
Thirty minutes with a senior partner. No charge, no slides.
-
2
Diagnostic
A few weeks on your premises or systems, at a fixed price agreed up front.
-
3
Costed plan
Findings for your board and a fixed-price plan you can take to anyone, including us.
02 · Investigations
Compliance investigations, run to an evidential standard.
When something has gone wrong, or might have, you need facts that will survive a regulator, a board and, if it comes to it, a court. We find them, show where each one came from, and tell you plainly what they mean.
Internal investigations
Allegations of misconduct, whistleblowing reports and control failures. Scoped with your counsel and run under privilege where that is appropriate.
Look-back reviews
Transaction and customer reviews over a defined period, with a sampling method your regulator can follow and repeat.
Due diligence
Counterparties, agents, suppliers and acquisition targets: ownership, control and reputation, traced back to source documents.
Sanctions and ownership tracing
Who really sits behind a customer, a supplier or a vessel, and whether any route leads to a sanctioned party.
Regulatory response support
We guide your team as you prepare your own responses and evidence, and join you in supervisory meetings when you invite us.
Evidence bundles
Every finding tied to an exhibit and every exhibit to its source, assembled for counsel, a board pack or court.
We report what the evidence shows, including when it shows nothing. A clean result, properly evidenced, is still a result.
03 · Monoclue
Private pilot · early access by invitation
Monoclue: the case management system we built for our own investigations.
The tools we used treated evidence as attachments. In Monoclue the evidence is the case. Every exhibit is fingerprinted when it arrives, every statement in a report points to the exhibit behind it, and nothing leaves the system without a record of who released it.
- Chain of custody
- Exhibits fingerprinted on arrival, originals locked, every action logged.
- Claims that cite their evidence
- A report can't be released while a statement in it is unsupported.
- Sources kept apart
- Confidential source identities sit in a separate vault, encrypted end to end.
- Walls between clients
- Staff see only the matters they're assigned to, with conflict checks at intake.
- Reports written by people
- An editor with checks for consistency, dates and citations before anything goes out.
- Bundles and client access
- Court and exhibit bundles in one step. Clients read released material in a watermarked portal.
- Deletion you can prove
- Matters closed out on schedule, legal holds respected, with a certificate of deletion.

How we work
What you can hold us to.
-
Your data stays with you
We work inside your environment, read-only wherever we can. Nothing is copied out that doesn't need to be.
-
The people you meet do the work
Named senior practitioners on every engagement. If a partner firm helps us, you'll know who they are and approve them first.
-
Every decision has an owner
Tools can recommend. Your people decide, and the record shows who decided what and why.
-
We never grade our own work
If you want independent validation of what we've built with you, it comes from a separate firm.
We have your back.
From the first finding to the day the regulator closes it, we work alongside your team. We guide you as you prepare your responses and evidence, help you fix what needs fixing, and support you in supervisory meetings at your invitation.
Who we are
Four founding partners and a bench of specialists.
Before Arventis, we built and ran compliance, risk and investigations functions inside some of the largest exchanges and trading firms in the world, in places where a missed alert or a failed audit has real consequences.
The firm is led by four founders as equal partners. Around them is a bench of former supervisors, reporting officers and investigators, each screened for conflicts before they join an engagement.
Contact
Tell us what's happening.
A few lines is enough: what has happened or what's coming, roughly how big the team is, and how much time you have. A partner will reply, usually within one business day. What you send us is treated as confidential.
