Our Story

From cloud-native expertise to AI-powered tender evaluation, we build products that let teams focus on people—not paperwork.

Founded in 2022

Donar Cloud-Architects began as a boutique engineering firm in Munich. Recognizing how much time organizations spend evaluating European tenders, we set out to streamline the process with cloud-native engineering and intuitive tools.

Launched Tenderbot IO in 2025

After extensive R&D and real-world testing, we launched Tenderbot IO—an easy-to-use platform that streamlines European tender evaluation and cuts admin work by up to 75%*.

Save Time and Make Better Tender Decisions

Focus on the tenders that matter—Tender Bot automatically screens EU-wide public opportunities, ranks them against your capabilities, and delivers a shortlist you can act on. Spend less time sifting through notices and more time crafting winning proposals.

* Internal benchmark tests (July 2025) show that an experienced analyst needs about 15 minutes¹ to perform the first-pass qualification of a typical EU tender. With TENDERBOT IO, that same analyst can pre-qualify roughly 150 tenders in the same 15 minutes — around 10 tenders in ± 1 minute. This represents a reduction in screening time of well over 90 %. To stay conservative and cover variations in document length and working style, we therefore communicate “up to 75% time savings.

¹ Calculation assumes an average reading speed of ~2 minutes per A4 page and an average tender length of ~7 pages.
