Enterprise software engineered for organisations that cannot afford failure.
Three platform generations engineering the complex-enterprise application stack — ERP, warehouse management and the application platform underneath. In production at industrial, distribution, retail, healthcare and public-sector enterprises where the day cannot afford an outage.
Since 1988
A modern software engineering company with a 38-year heritage. Three platform generations behind us, an AI-native runtime in front — engineered today by second-generation leadership and a new generation of engineers.
Three continents
Established across Europe, Latin America and Asia — Spain (Barcelona, Madrid, Sevilla), Peru (Lima), Colombia (Bogotá), Pakistan (Islamabad). One engineering team across regions, accountable to one customer at a time.
Mission-critical by default
Industrial operations, distribution, retail, healthcare and public sector — environments where downtime is measured in lost revenue and lost trust.
Independent · Customer-funded · No private equity
Owner-engineered. Growth funded by customer revenue, never by private equity. The engineering team owns the stack ; no reseller layer, no opaque vendor in the middle.
The Axional family — three applications, one platform underneath.
Three applications, engineered together by one team on the Airtool platform. Adopt one or several. The platform underneath them is a separate brand surface, available globally on its own at airtool.io.
ERP
The complex-enterprise ERP. Finance, procurement, supply chain, manufacturing, multi-entity, multi-currency. Engineered for organisations where the global ERP standard is overkill or wrong-fit. Spain · Peru · Colombia fiscal depth available; additional regimes engineered as commercial requirements warrant.
WMS
Warehouse management for high-throughput, high-traceability operations. Industrial heritage; healthcare-grade traceability; pharma-grade controls. Standalone or paired with the ERP on one runtime. The same engine is sold globally under the Airtool brand — see Airtool · Solutions.
Healthcare
The administrative engine for hospital networks — patient administration, revenue cycle, physician compensation and regulated procurement. Integrated with the clinical HIS via HL7 and FHIR ; not a clinical HIS itself. In production at Quirónsalud, Europe's largest private hospital group.
They configure. We engineer.
The Big-Four firms sell ERP transformation for hundreds of millions of euros a year. Their programme management is excellent, their change practices are mature, their analysts are senior. The structural difference is what they ship at the end of a phase: configurations of a vendor's software they did not write. When the configuration meets an operational reality the vendor did not anticipate, they can only file a ticket and wait.
We sell the same programme shapes. The configuration boundary that breaks Big-Four engagements is, for us, the engineering boundary we already control.
Why deister software
The shortlist. Six advantages, all anchored in what deister software actually does.
A modern engineering company with 38 years of mission-critical delivery
Founded 1988. Second-generation leadership today, AI-native runtime in production, a new generation of engineers building the platform forward. The 38-year heritage is the depth, not the surface.
An owned proprietary stack
ERP, application platforms and operational tooling — engineered and owned by us across thirty-eight years. No reseller dependency, no opaque dependency in the middle.
Localisation engineered, not bolted on
Where the global ERP standard adds regulatory localisation as a partner-pack add-on, ours is engineered at the engine tier. Spain, Peru and Colombia in production today; additional fiscal and regulatory regimes engineered as commercial requirements warrant.
Production-tested across regulated industries
The same engine runs the back office of national healthcare networks, industrial operations, retail at scale and public administration. If it survives the regulation, the audit and the operational tempo those industries require, it will run yours.
Long-horizon customer relationships
Most of our active customers have worked with us for more than ten years. The team that delivers the programme is the team that runs the system afterwards.
A senior, distributed delivery model — 24-hour engineering coverage
Three continents, four time zones — Spain, Peru, Colombia and Pakistan. The spread across Madrid, Lima, Bogotá and Islamabad gives our customers 24-hour engineering coverage across the working day : an Islamabad engineer is on the codebase before Madrid wakes up, a Lima or Bogotá engineer is on it after Madrid closes. Senior, distributed, fewer hand-offs, faster decisions, lower TCO than the big four systems integrators.
The complexity test
Healthcare is where every cliché about enterprise software dies. Regulated. Multi-entity. Real-time. Procurement-heavy. Billing-deep. Integrated with national health systems. Audited across every record. The day cannot afford an outage.
We have run healthcare in production for years. Every other vertical we serve — distribution, retail, logistics, industrial operations, public sector — is a subset of that complexity, not a superset. The healthcare practice is detailed under Industries.
Regional editions
Country-targeted home pages, each leading with the claim that registers strongest in that market. The canonical product, services and customer surfaces are the same across editions.
Peru — Edición Perú
The Peruvian edition, in Spanish. SUNAT CPE, libros electrónicos, IGV and ESSALUD engineered into the engine. The Lima delivery centre and the regional fiscal-compliance lead.
Colombia — Edición Colombia
The Colombian edition, in Spanish. DIAN factura electrónica, RUT, IVA and retención en la fuente engineered into the engine. The Bogotá operation and the local fiscal-compliance lead.
Pakistan — Pakistan edition
The Pakistan edition, in English. Airtool platform, Apps suite, technical services and legacy replacement — with a commercial reach across Pakistan, the Gulf and the wider South Asia / MENA region. The Islamabad platform engineering centre.
