What Keeyns does
Keeyns B.V. is a Netherlands-based SaaS company founded in 2017 by brothers Ruben van Aarle (CEO) and Ramon van Aarle (COO), both former tax partners at the Dutch advisory firm Taxperience. The company sells a cloud-based tax collaboration platform, hosted on Microsoft Azure with EU data residency, that centralises tax workflows, documents, and data for international and multi-entity companies across more than 150 countries. The product is modular, comprising Collaboration Dossiers, Compliance Dashboards, User Management with role-based access and SSO, Workflow Automation, native Microsoft Office integration, and a planned suite of specialised Tax Engines for areas such as VAT, corporate income tax, and transfer pricing.
The platform is positioned as purpose-built for tax professionals rather than a generic project management tool, with features such as full audit trails, contextual commenting, traffic-light compliance status dashboards, and configurable filing workflows that link internal tax teams with external advisors. Reported customer outcomes include a 40% improvement in compliance efficiency, a 60% reduction in internal email volume, and a 22% reduction in advisory costs. Keeyns is ISO 27001 certified and operates with per-client database isolation and dedicated encryption keys.
The business operates on a subscription model with monthly billing in advance, usage-based tiering tied to number of users, entities, territories, and storage, and custom pricing delivered through Order Confirmations. Go-to-market combines direct enterprise sales, channel partnerships (Seed Group in MENA, Lumber in construction), industry event participation, content marketing, and a founders-hosted podcast. The company has offices in 's-Hertogenbosch (HQ), Porto (R&D), and Dubai (MENA hub), and raised €10 million in March 2024 from Alea Capital Partners and Mountainview Capital Partners to fund European and U.S. expansion and the development of AI-enabled tax engines.

Keeyns competitors and assessment
Company assessmentDirect peers
- Vertex: Established indirect tax (VAT, sales tax) technology vendor offering compliance engines and e-filing solutions. Directly comparable to Keeyns' VAT and compliance workflow capabilities, though Vertex is more focused on tax calculation engines while Keeyns emphasizes collaboration and workflow.
- Sovos: Global tax compliance platform covering VAT, sales tax, withholding and e-invoicing. Competes directly with Keeyns for the multi-jurisdiction indirect tax compliance budget of multinationals, with similar enterprise go-to-market motion.
- Canopy: Tax practice management software offering workflow, document management, and client collaboration. Overlaps with Keeyns' collaboration and workflow automation capabilities, primarily serving tax firms rather than in-house tax teams.
- TaxDome: Practice management and collaboration platform for tax and accounting firms. Comparable workflow and collaboration functionality, but targets accounting firms and their SMB clients rather than corporate tax departments at multinationals.
Broad incumbents
- Avalara: Sales and use tax automation platform with broad SMB and mid-market reach. Comparable to Keeyns in automating tax workflows and filings, but primarily US sales-tax focused and serves a different buyer segment than Keeyns' multi-entity European multinational niche.
- Longview Tax (now part of insightsoftware): Corporate tax provision, planning and compliance software targeting large enterprises. Overlaps with Keeyns' tax reporting and compliance workflows for multinationals, but is centered on tax accounting and ERP integration rather than advisor collaboration.
- Thomson Reuters ONESOURCE: Large incumbent corporate tax software suite covering corporate income tax, indirect tax, transfer pricing and tax reporting. Competes broadly with Keeyns but as part of a much wider portfolio aimed at large enterprises, not a purpose-built collaboration platform.
- Wolters Kluwer CCH Tagetik / CCH Integrator: Major tax and accounting technology vendor serving corporations and accounting firms. Overlaps with Keeyns in corporate tax compliance and reporting, but offers broader tax, audit and performance management capabilities rather than a collaboration-first model.
Emerging players
- Blue J: AI-powered tax research and decision-support platform for tax professionals. Comparable as an emerging tax-tech vendor targeting corporate tax departments, with overlapping buyer personas but a different product focus (research vs collaboration).
- Indy (Indy Tax): Cloud-based tax collaboration and practice management tool for modern accounting firms. Shares the 'collaboration-first' positioning with Keeyns and competes for workflow budget at tax advisory firms serving SME clients.
