aid: donnerstag-ai name: Donnerstag Ai description: >- Donnerstag.ai (Donnerstag.ai Technologies GmbH) is a Frankfurt-based enterprise fintech building an AI Reconciliation Layer for enterprise finance. Its platform automates financial reconciliation at the line-item level across accounts payable, accounts receivable, bank, and intercompany flows, adapting to each customer's systems, data sources, workflows, and roles. The stated goal is 100% line-item coverage at T+0 so the financial close becomes a confirmation rather than a month-end scramble, with an immutable audit trail for GoBD, IFRS, SOX, and BEPS. The company serves logistics, payment service providers, retail and e-commerce, manufacturing, human resources, and construction, is EU-hosted in Frankfurt, and is founded by Barbaros Ozbugutu and Volkan Ozkan and backed by Speedinvest. As a solution-and-services provider it exposes no public developer API, SDK, or docs. accessModel: pricing: unknown onboarding: unknown trial: false try_now: false public: false label: Unknown confidence: low source: [] generated: '2026-07-22' method: derived image: https://framerusercontent.com/images/iAFSOvcJWm86sIBCSWs4r44RdvY.png url: https://raw.githubusercontent.com/api-evangelist/donnerstag-ai/refs/heads/main/apis.yml x-type: company x-source: vc-portfolio x-backed-by: - speedinvest x-tier: profile x-tier-reason: portfolio-lead-enriched specificationVersion: '0.20' created: '2026-07-17' modified: '2026-07-18' tags: - Company - Fintech - Reconciliation - Enterprise Finance - Financial Automation - Accounts Payable - Accounts Receivable - Artificial Intelligence - Payments - Germany apis: [] maintainers: - FN: Kin Lane email: kin@apievangelist.com - FN: APIs.json email: info@apis.io common: - type: Website url: https://www.donnerstag.ai/ - type: Blog url: https://www.donnerstag.ai/resources/blog - type: Whitepapers url: https://www.donnerstag.ai/resources/whitepapers - type: PrivacyPolicy url: https://www.donnerstag.ai/privacy - type: TrustCenter url: security/donnerstag-ai-trust-center.yml - type: Compliance url: https://www.donnerstag.ai/trust - type: DomainSecurity url: security/donnerstag-ai-domain-security.yml - type: Contact url: https://147471513.hs-sites-eu1.com/en/book-a-meeting - type: LinkedIn url: https://www.linkedin.com/company/donnerstag-ai - type: Imprint url: https://www.donnerstag.ai/imprint x-enrichment: date: '2026-07-19' status: backfilled pass: local-v1 note: backfilled from .gitignore signal + verified work evidence
