About Jan Henner-Theißen
Jan-Henner Theißen has worked in procurement for close to three decades. He began with a vocational apprenticeship at the drilling company Deutsche Tiefbohr (DEUTAG) in 1994. He later earned a business degree (Dipl.-Kfm.) at Hochschule Osnabrück.
He held procurement strategy roles at Benteler Automobiltechnik from 2004 to 2011, including positions in Michigan and Paderborn. He joined AGCO in November 2011 and became Director Strategy & Methods in Global Purchasing, based in Georgia, USA. AGCO won the BME eSolutions Award in 2015 for its risk management work, and in 2016 he and his logistics colleagues won the BVL Innovationspreis.
Since 2017 he has run targetP!, a procurement consultancy he founded, and he also takes interim procurement leadership roles. He joined the advisory board of the procurement analytics company SCALUE in April 2020. With Stefan Wiemers he co-authored the book "Digitaler Einkauf im Mittelstand".
The only public angel investment we found is Elevatry. Crunchbase lists one personal investment for him. The public record does not show other angel deals, a fund, or a check size.
Elevatry announced a €3M pre-seed round on 15 October 2026. Bayern Kapital and the management consultancy H&Z took part, along with several business angels, including Jan Henner-Theißen. The company, based near Munich, builds an agentic AI platform for strategic procurement. Its AI "Companions" cover the source-to-contract process, from needs analysis and sourcing strategy to supplier selection, should-cost analysis and negotiation. The platform went live on 28 September 2026. Elevatry plans to start in Germany, Austria, Switzerland and the wider EU, and to enter North America later.
Too little is public to define a thesis. His one known angel investment is a pre-seed round in AI software for corporate procurement. This fits his career in purchasing and supply chain, where he has spoken publicly about digitalizing procurement in mid-sized companies. He has not published a check size, stage preference or geography for his angel investing.
