Competitor Profile
Where this is heading
Grupo Castilla sells labour-law expertise with software attached, not the reverse. Consultants, legal advice and outsourced payroll production sit alongside three products, and in a country where employment terms are set by sectoral and regional collective agreements, the people who interpret them are the product.
It publishes a checkable strategic plan , €45m revenue and 500 people in 2026 , which is rare in this market and cuts both ways. The implied revenue per head describes a services business rather than a software one, and the stated ambition to become a national HCM cloud provider is a commitment to change that mix on a dated timetable.
Its sharpest competitive threat is domestic. Factorial is Spanish, venture-scaled and positioned in Spanish coverage as the most advanced AI payroll product for 10 to 500 employees , squarely Grupo Castilla's range. An incumbent facing a local AI-led challenger has no home-knowledge advantage to fall back on.
Three products against one statutory regime is a structural cost. Every Spanish social-security and tax change must land in Epsilon RH, Omne RH and Delta RH separately, where a single-platform competitor absorbs it once.

How the product hangs together, at the level a product leader needs to place it.
Grupo Castilla is one of the leading Spanish-owned companies in HR software and knowledge services, founded in 1979 and serving more than 3,800 clients. It describes itself as its clients' HR partner rather than their software vendor, and the product and service mix bears that out.
The software estate is three distinct products rather than one platform, which is unusual and tells you the company has grown by addressing segments rather than by generalising:
- Epsilon RH is the flagship people-management system, integrating payroll with time and attendance control, talent management and internal communication. - Omne RH is a SaaS payroll solution natively integrated with Microsoft Business Central , a deliberate play for the Spanish company that has standardised on Microsoft's mid-market ERP. - Delta RH is an integrated solution for smaller businesses covering labour, fiscal and accounting matters alongside invoicing, warehouse and logistics.
Alongside the software sits a services business that is central rather than peripheral: recruitment, training, consultancy, legal advice and payroll outsourcing. The company manages an average of close to 30,000 payslips monthly through that outsourcing operation.
The strategic plan is published and specific, which is rare in this set. Grupo Castilla targets €45 million of revenue in 2026 with a team of 500 professionals, and states the goal of becoming the national reference HCM cloud provider. A vendor that publishes a revenue target and a headcount target is a vendor whose progress can be checked against its own stated intentions , and that is a genuinely useful thing for a competitor to be able to do.
03
Geographic footprint, and where payroll is native rather than partner-delivered.
Grupo Castilla competes across the Spanish market from small business to mid-market, and its distinguishing characteristic is that it sells consulting alongside software to a degree most competitors do not.
The Spanish market splits between software built for labour advisories , where Wolters Kluwer's a3innuva Nómina and TeamSystem Nominasol are the standard , and all-in-one SaaS for SMEs managing payroll themselves, where PayFit and Factorial lead. Grupo Castilla sits across that divide, selling software to companies and payroll services to companies that would rather not, which is the same both-sides position Nibelis holds in France.
Against Factorial, the Barcelona-headquartered competitor in the same country, the contrast is generational and philosophical: Factorial is venture-scaled, automation-led and internationally expanding; Grupo Castilla is 47 years old, consulting-led and explicitly domestic. Against Cegid, which reaches Spain through Meta4, Grupo Castilla is the local independent against an international group. Against Personio and Bizneo HR, it holds the payroll engine those platforms integrate to , Bizneo lists Grupo Castilla and Epsilon among the payroll systems it connects with, which makes the relationship partnership and competition simultaneously.
The Microsoft Business Central integration is the most strategically interesting product decision here. Business Central is Microsoft's mid-market ERP, and a payroll product natively integrated with it reaches every Spanish company that has standardised on the Microsoft stack. That is the same structural position NetSuite SuitePeople occupies for NetSuite customers , payroll sold as an extension of the finance system rather than as a competitor to it , and it is a distribution route rather than a feature.
The consulting and legal-advice business is the durable differentiator. Spanish labour law is administered through collective agreements at sector and regional level, and a vendor that also employs the people who interpret them is selling something a pure SaaS product cannot.
04
No public price list; Grupo Castilla sells through direct engagement and prices software and services together, which is consistent with a consulting-led model where the software is one component of a relationship.
The published strategic plan is the most useful commercial disclosure available and it can be read as a competitive statement. €45 million of revenue in 2026 with 500 people implies roughly €90,000 of revenue per employee , a ratio characteristic of a services-weighted business rather than a software one, where a pure SaaS vendor at that revenue would typically run far fewer people. That is not a criticism; it is a description of what the company is. The stated ambition to become a national reference HCM cloud provider signals an intent to shift that mix toward software, and the revenue-per-head ratio is the number to watch to see whether it happens.
The three-product structure carries a cost that should be named. Maintaining Epsilon RH, Omne RH and Delta RH means three codebases against one set of Spanish statutory changes. Every Seguridad Social or IRPF amendment has to land three times. For a company of 500 people that is a meaningful ongoing tax on engineering capacity, and it is the most likely internal argument for consolidation.
The outsourcing volume , close to 30,000 payslips monthly , should be read as the managed-service book rather than as total platform volume across 3,800 clients. ⚠️ The vendor does not publish a total payslip figure and the two numbers should not be combined.
05
No named AI capability was located for Grupo Castilla in published sources, and no automation, accuracy or evaluation disclosure was found.
The positioning is functional breadth plus consulting depth: the company differentiates on the combination of software with a team of labour consultants and technical specialists holding deep Spanish HR knowledge. That is a human-expertise proposition, and the vendor markets it as such.
In the Spanish market specifically this is a visible gap rather than a neutral one. Spanish market commentary describes Factorial as the most advanced AI payroll product in the market for companies of 10 to 500 employees, which is squarely inside Grupo Castilla's range. Factorial is Spanish, well funded and competing for the same buyer with automation as its headline. A 47-year-old Spanish incumbent facing a Spanish AI-led challenger in its own market is a much sharper competitive situation than an incumbent facing a foreign one.
There is a structural tension worth naming, because it recurs across this set. Grupo Castilla's differentiator is a team of consultants and labour-law specialists. Automation that reduces the need for that team reduces the value of the differentiator, and it also reduces billable services work. A consulting-led vendor has a weaker commercial incentive to automate than a product-led one, which is a coherent explanation for the absence and not an excuse for it.
The stated ambition to become a national reference HCM cloud provider implies a shift toward software economics. Whether AI capability accompanies that shift is the question to watch, and the strategic plan gives a dated frame , 2026 , in which to watch it.

Diagnosis and the play together. Each is a live attack vector, not a general weakness.
No published AI position against a Spanish AI-led competitor in the same segment. Factorial is described in Spanish market coverage as the most advanced AI payroll product for the 10-to-500-employee range, which is Grupo Castilla's core. This is not a foreign disruptor arriving with a generic pitch; it is a domestic competitor with the same statutory knowledge and a different technology story.
Three products, one statutory regime. Epsilon RH, Omne RH and Delta RH each have to absorb every Spanish labour and social-security change. A single-platform competitor absorbs it once, and over time that difference compounds into either slower response or higher cost, or both.
Spain only, in a market where mid-sized companies internationalise. A Spanish client opening in Portugal, France or Latin America must add another provider. Cegid via Meta4, PayFit across France and Spain, and Personio across DACH and Iberia can all follow where Grupo Castilla cannot.
The consulting model has an automation problem. Revenue tied to consultants, legal advice and outsourced payroll production is revenue that automation erodes. A competitor selling automation to the same buyer is selling against Grupo Castilla's own cost structure , the same structural tension recorded for Cegedim SRH in France and Nethris in Canada.
A published target is a published target. €45 million and 500 people in 2026 is a commitment against which the company can be measured, including by competitors. That is admirable transparency and it is also a hostage: if the plan slips, the slip is checkable.
Where it is not beatable. Forty-seven years of Spanish labour law, a consulting team that interprets sectoral and regional collective agreements, and 3,800 client relationships. For a Spanish company with a complicated collective agreement and no international ambition, the combination of software and people who know the law is a genuinely strong offer, and an automation-led competitor cannot replicate the second half quickly.
