D4 Solutions

What D4 Solutions does

D4 Solutions Ltd. is a privately held, Northern Ireland–registered Workday consultancy (company number NI679687) founded in 2021 and headquartered at 6 Oak Country Avenue, Derry (Londonderry), United Kingdom. The firm specializes in post-deployment Workday services, organized around four functional specialisms: Integrations (covering EIBs, Web Services, Cloud Connect, Studio, and Third Party Payroll), Financials (General Ledger, Accounts Payable, Accounts Receivable, Fixed Assets, Expenses, and Financial Reporting), Human Capital Management (HCM), and Reporting. The core technology is human-delivered consulting on top of the Workday platform; the company does not develop proprietary software, APIs, or AI tooling.

The business model is professional services revenue derived from billable consulting hours and project engagements. D4 Solutions uses a sales-led go-to-market approach with direct client engagement via phone, email, and website contact form, offering flexible engagement structures that range from fixed-term projects to longer-term consulting initiatives under a 'no job too big or too small' framing. Pricing is not publicly disclosed and is bespoke to each engagement. The customer segment is horizontal: organizations that have already implemented Workday and seek to optimize the investment, address underutilized functional areas, improve integration efficiency, maximize reporting, and build internal capability.

The firm operates with 1–10 employees, has no disclosed funding rounds, no parent company, no subsidiaries, no named customers or case studies, and no disclosed partnerships, patents, trademarks, awards, or AI capabilities. Distribution is exclusively direct, single-country (United Kingdom), with limited marketing presence beyond the company website. Leadership visibility is minimal; Kevin Stirtz is the only named individual associated with the firm and is quoted on the website articulating its guiding principle, with no formal designation disclosed.

• IBM Consulting: Enterprise consulting arm of IBM with certified Workday capabilities and a global delivery footprint, competing for transformation and integration mandates.
• Accenture: Global system integrator with deep Workday capabilities across HCM, Financials, and integrations, delivering enterprise-scale transformation projects that D4 cannot resource.
