Kaldros
What Kaldros is
Kaldros is a web-based retrieval engine for enterprise AI that returns cited answers from company messages, documents and tickets. Before retrieval, it applies permissions from connected source tools, so the model receives only content the user asking a question can access. Its product surfaces include Ask for answers, Events for a permission-filtered event timeline and Connectors for connected systems. Kaldros lists 16 live sources, including Slack, Google Workspace, Microsoft 365, GitHub, Notion, Linear, Atlassian, Salesforce, Stripe, HubSpot, Calendly, GitLab, Intercom, Asana and Zendesk. Data is processed in EU datacenters with failover within the EU; Enterprise can pin residency to a specific jurisdiction. Kaldros says data is encrypted at rest with AES-256 and in transit with TLS 1.3, with BYOK available on Enterprise. Permission changes, answers and connector actions create chain-hashed audit entries that can be verified and exported to a SIEM. Pricing starts at €39/user/mo annually; Team and Business offer a 14-day trial requiring a payment method.
Who it suits
Kaldros is aimed at organizations that need permission-aware answers across connected company sources. Its Enterprise offering is described for regulated industries and scale-ups past Series C that need procurement, security or legal controls.
