Flow and Tarth solve adjacent problems, and it is worth being precise about the difference before you choose. Flow is a software platform for private investment funds that runs the full limited-partner lifecycle: virtual data rooms, digital subscriptions, an investor portal, capital calls, fund reporting, and K-1 distribution. KYC/AML sits inside that suite as one module — it collects investor data and documents through digital workflows, then runs identity checks and AML, PEP, and sanctions screening with configurable thresholds. Flow now operates as part of Apex Group, a global fund-administration group, and its positioning and traction are centred on US private markets.
Tarth starts from the opposite end. It is a compliance-first product whose entire reason for existing is the depth and defensibility of the customer due diligence decision. Rather than collect-and-screen, Tarth reasons through each case as an AI agent: it works a natural person through identity, PEP, sanctions, adverse media, and source-of-wealth, then produces an audit-ready customer assessment file in which every conclusion is traceable to the evidence behind it.
The honest framing is depth versus breadth. If you need a unified LP experience across the whole investment lifecycle, Flow is purpose-built for that and does it well. If your binding constraint is producing a defensible, examiner-ready CDD file aligned to a specific Gulf or offshore rulebook, that is the problem Tarth was built to solve.
Where the two products genuinely differ
Flow’s strength is structured data and workflows feeding fund operations — subscriptions, capital calls, reporting, all in one place for the LP. The KYC module is real and capable, but it is a feature within a lifecycle suite, and its screening is described in Flow’s own materials as identity verification plus standard AML/PEP/sanctions checks with configurable security thresholds.
Tarth’s strength is the reasoning and the output. The unit of work today is deep per-natural-person screening — roughly ten minutes per person — with a risk assessment carried out for each individual rather than a single pass/fail at the account level. The signature deliverable is not a screening result but a reasoned file: each decision links to its source, so an MLRO or examiner can see not just what was concluded but why, and against which rule.
The third difference is jurisdiction. Flow’s footprint and language are US private markets. Tarth is built around the ADGM/FSRA, DIFC/DFSA, and Cayman/CIMA rulebooks — the Gulf and offshore-fund domiciles that most LP-onboarding platforms treat as edge cases. The CDD files Tarth produces are mapped to the governing jurisdiction’s requirements, not to a generic onboarding template.
Feature comparison
| Tarth | Flow | |
|---|---|---|
| Core category | AI-native KYC/AML compliance agent | LP lifecycle / investor onboarding platform |
| KYC/AML role | The whole product — reasoned CDD decisions | One module within a broader fund-ops suite |
| Primary output | Citation-backed, audit-ready CDD/CAF file | Investor onboarding records + identity/AML screening results |
| Decision model | AI agent reasons across the case | Data capture + configurable identity & screening checks |
| Per-person depth | Deep per-natural-person screening (PEP, sanctions, adverse media, source of wealth) | Investor-level identity and AML checks within subscription flow |
| Jurisdiction focus | DIFC, ADGM, Cayman, Singapore, BVI, Mauritius | US-centric private markets |
| Full LP lifecycle (data room, capital calls, K-1) | Not in scope | Yes — full investor lifecycle suite |
| Corporate context | Zest Technologies DIFC Limited | Part of Apex Group |
Flow runs the LP’s journey end to end; Tarth makes the compliance decision defensible end to end.
When Flow may be the better fit
If your priority is a single platform that carries limited partners through subscriptions, capital calls, reporting, and K-1s — and KYC/AML is one box to tick within that flow — Flow is a genuinely strong choice, especially for US-domiciled private-markets managers who want a polished LP experience and the backing of a large fund-administration group. Tarth does not run capital calls, data rooms, or investor reporting, and is not trying to. Choose Tarth when the CDD file itself — its depth, its citations, its alignment to a Gulf or offshore regulator — is the thing that has to be right.
Frequently asked questions
Is Tarth a direct replacement for Flow?
Not exactly. Flow is a full LP-lifecycle platform; Tarth is a compliance agent focused on the KYC/AML decision and the audit-ready file. Firms that need Flow’s subscription, capital-call, and reporting features use it for that, while turning to Tarth where regulator-grade CDD depth and citation-backed evidence matter most.
What does Tarth produce that Flow’s KYC module does not?
A reasoned, citation-backed customer assessment file. Flow’s module performs identity verification and AML/PEP/sanctions screening and stores the results. Tarth’s agent reasons through each natural person and produces a file in which every conclusion traces to its source evidence and to the relevant rulebook — built to be handed to an MLRO or examiner.
Does Tarth work for US funds?
Tarth can screen individuals connected to any fund, but its native strength is the Gulf and offshore-fund domiciles — DIFC, ADGM, Cayman, Singapore, BVI, and Mauritius — where its files are mapped to the specific governing rulebook. Flow’s positioning is US-centric private markets.
Does Tarth handle entity-level KYB and ownership graphs?
Tarth 1.0 is focused on deep per-natural-person screening, with a customer risk assessment per person. Entity-level KYB, batch close-mode, and ownership-graph features are on the roadmap and not yet shipped.
Is Flow still an independent company?
Flow is now part of Apex Group, a global fund-administration group, as stated on Flow’s own site. That can be a strength if you want fund administration and onboarding under one roof.
