Technology company · Madrid, Spain
Kalkar designs and builds proprietary SaaS platforms that automate the operational and financial work of companies. Our own products on one architecture: applied AI with guardrails, security by design and the ability to scale without installing anything on customer premises.
In production. MIMO and Taxdity run in production at a 14-unit aparthotel in Brussels.
Products
Each product addresses a different market on the same technology foundation: AI agents working on real data, native integrations and supervised automation.
For accommodation operators: hotels, aparthotels and serviced apartments. Guest messaging over WhatsApp, chat and phone, operations, revenue management and IoT security in a single platform.
For any company, SME or freelancer, in any industry. Connected banks, AI-read documents, invoicing, taxes, treasury and payroll. Set it up once and it runs on its own.
For security teams in companies and public bodies. It unifies events, incidents, vulnerabilities, assets and intelligence, investigates with AI agents and automates response with human approval.
Capabilities
Every action follows the same circuit: AI interprets the message or document and proposes what to do; business rules and confidence thresholds check it is right; if the action is sensitive, a person approves it; only then is it executed, with everything logged.
Example: a supplier invoice arrives. AI reads it and proposes the journal entry, rules validate tax ID, VAT and amounts, a person reviews anything above the threshold, and it is booked with a full audit trail.
Agents that answer calls with natural voice.
A dedicated network per property over an encrypted tunnel.
Multi-bank and payment gateways connected with nothing to download.
Least privilege, service isolation, web application firewall and encryption in transit.
One multi-client, multi-location architecture, with nothing installed on customer premises.
Spanish, English, French, Dutch, German and Italian.
