What Open Europe s.r.o. does

Open Europe s.r.o. is a privately-held Czech limited company (s.r.o., IČO 24667722, VAT ID CZ24667722) operating from Chržín, Czech Republic, that delivers independent cost control, project control, and process automation services to construction, industrial, and project-based organisations across the full project lifecycle—from tender preparation to close-out. The company sells a dual-track portfolio anchored on Right Menu, an Office Task Pane Add-in that runs entirely inside the local Excel process (no macros, VBA, ActiveX, AI, or data transmission to servers), providing vertical sheet navigation for workbooks with 20-150+ sheets, one-click workbook auditing across six categories (external links, hidden sheets, formula errors, numbers as text, merged cells, empty sheets), instant cross-sheet navigation, visual formula building, and a claimed proprietary method for separating linearly inseparable corporate data with 100% accuracy. The product is sold as Right Menu PRO (B2C personal subscription through the company website with Stripe payment processing, positioned as the 'most affordable consumer price') and Right Menu Enterprise (B2B organisational subscription via Azure Marketplace with centralised deployment through Microsoft 365 admin center), with both editions distributed and certified on Microsoft AppSource. The company is bootstrapped, with no institutional capital, no disclosed financials, no parent company or subsidiaries, and a two-person founding team—Elena Naumčiková (cost manager) and Oleg Naumčík (IT developer)—whose combined 30+ years of construction cost management and software development expertise underpin both the professional services and the Right Menu product line.

Products and services

• Right Menu PRO Personal Microsoft Excel Add-in for individual professionals (analysts, cost managers) working with large workbooks (20–150+ sheets). Provides vertical sidebar navigation with full sheet names and color indicators, one-click workbook audit across 6 categories (external links, hidden sheets, formula errors, numbers as text, merged cells, empty sheets), Teleport instant cross-sheet navigation, visual cross-sheet formula building (Link to), Copy from protected sheets, and Unmerge for fixing merged cells. Runs entirely locally inside Excel with no AI, no data collection, and no macro/VBA/ActiveX.
• Right Menu Enterprise Organizational Microsoft Excel Add-in for Microsoft 365 organizations, providing the same vertical navigation, workbook audit, cross-sheet tools, and cell-unmerging capabilities as Right Menu PRO but with centralized IT deployment via Microsoft 365 admin center and organizational licensing purchased on Azure Marketplace. GDPR-compliant, Microsoft AppSource certified (Microsoft 365 Certification in progress), positioned for compliance-conscious enterprises that need no data collection and no OAuth directory access.
• Cost Control Services Independent cost control services for construction, industrial, manufacturing, and project-based organisations. Covers budget breakdown structures, cost coding, cost reporting, EAC/ETC forecasting, variance analysis, cash flow monitoring, procurement support, invoice and payment application control, change order tracking, and project performance reporting across the full project lifecycle from tender preparation to close-out.
• Project Control Services Project control services for the full project lifecycle — from tender preparation through execution monitoring, change management, cash flow forecasting, and final cost reporting. Targets general contractors, developers, investors, asset managers, manufacturers, specialist contractors, and fit-out companies needing independent project oversight and customised reporting.
• Process Automation Services Process automation services that help project teams build flexible cost tracking and reporting solutions around the real project process (rather than forcing processes into ERP logic), using Excel, structured data models, and custom software tools to automate repetitive work, improve accuracy, and connect fragmented project data with decision-ready reporting.
• Digitalisation & Analytical Layer Services End-to-end digitalisation projects that connect primary corporate data sources directly with analytical outputs, using a proprietary method for separating linearly inseparable data with 100% accuracy. Creates an independent analytical layer between working documents, ERP systems, BI tools, and management reporting, reducing duplication, manual corrections, and loss of context across the complete data digitalisation cycle.

Broad incumbents

• Oracle Primavera Unifier: Enterprise cost and project controls platform for capital projects in construction and industrial sectors. Comparable to Open Europe's cost control/projection services target customers, but a much heavier enterprise-grade system.
• Procore: Leading construction management platform covering cost control, project controls, change orders, and reporting for general contractors and owners. Comparable to Open Europe's professional services scope, though operates as broad SaaS platform rather than focused Excel/services delivery.
• Autodesk Construction Cloud: Suite of construction management products (including former BIM 360 and Pype) covering cost, project, and document control. Overlaps with Open Europe's cost control and project control services for construction organisations but serves a much broader enterprise footprint.
• Microsoft Copilot for Excel: Microsoft's own AI-powered Excel assistant embedded in Microsoft 365 — the most significant platform-level threat to Right Menu. Provides natural-language formula generation and analysis directly within Excel, potentially subsuming Right Menu's value proposition.
• Sage 300 Construction and Real Estate: Construction accounting and project management software serving general contractors and developers. Comparable to Open Europe's target customers (general contractors, developers) for cost control and reporting workflows.

Direct peers

• Power-user: Excel and PowerPoint productivity add-in offering navigation, formula, and visualisation tools to business users. Comparable target customer (analysts, cost managers) and Microsoft AppSource distribution model.
• XLTools.net: Excel add-in focused on version control, workbook auditing, and team collaboration for large workbooks. Comparable to Right Menu's audit, navigation, and cross-sheet features for users managing 50+ sheet workbooks.
• ASAP Utilities: Long-established Microsoft Excel add-in providing productivity tools (sheet navigation, workbook utilities, formula helpers) to professional Excel users. Directly comparable to Right Menu in product category, target persona, and Microsoft 365 distribution model.
• Kutools for Excel: Widely-used Excel add-in suite offering navigation, formula, and workbook management features for individual professionals and enterprises. Competes head-to-head with Right Menu on Microsoft AppSource and similar productivity positioning.

Emerging players

• CostCertified: Construction estimating and cost management platform targeting general contractors with digital takeoff and reporting tools. Comparable to Open Europe's construction cost control focus but operates as purpose-built SaaS rather than Excel-based services.
