Swiss banking technology firm Temenos has agreed to acquire fintech Additiv, with the 50/50 cash and equity deal eyeing a completion date as early as Q3 of 2026. Additiv, through its technology, integrates process steps and data into a single orchestration layer for wealth and other financial workflows.
With clients in wealth management, banking, and insurance, the venture’s technology enables banks and wealth managers to rapidly design and launch wealth propositions that boost advisor productivity, orchestrate investment propositions, and provide consistent client experiences at scale.
“With an extensive global client base in the wealth space, Temenos will benefit from Additiv’s native mass-affluent capabilities and AI-enabled orchestration layer. The company’s fast, low-risk implementation model offers deployments in as little as 3-6 months compared to the industry standard of 12 months. With a high Net Promoter Score (NPS) above 90, Net Revenue Retention (NRR) of 138%, and double-digit growth over the past three years, Additiv will enable Temenos to expand its client footprint within investment services in both developed and emerging markets, as well as provide Temenos’ wealth clients with future-ready, front office workflows,” Temenos commented.
“This acquisition strengthens our wealth proposition at a time when we see strong, growing demand for our products across tiers and geographies in the wealth segment, with financial institutions increasingly focused on launching scalable hybrid wealth models. Additiv’s orchestration capabilities complement our market-leading platform and support our strategy to help clients deliver personalised, regulatory-compliant wealth services efficiently and at scale. Together, Additiv’s AI-powered orchestration capabilities and Temenos’ existing front-end solutions create strong differentiation at the banking experience layer,” said Additiv founder Michael Stemmie.
Temenos, on the other hand, offers a core banking suite, along with modular, composable solutions, to help banks and other financial institutions modernise their operations. Deployable on-premises, via the cloud, or as a SaaS solution, Temenos’ technology empowers financial institutions of all sizes to deliver innovative, AI-enhanced experiences to their customers. Founded in 1993 and based in Switzerland’s Geneva, Temenos, as of June 2026, serves more than 950 core banking and 600 digital banking clients. Thibault de Tersant is Temenos’ chairman, while Takis Spiliopoulos is the venture’s chief executive officer (CEO) and interim chief financial officer (CFO).
Headquartered in Zurich, Switzerland and founded in 1998, additiv offers an API-first, cloud-based financial services orchestration platform that enables financial institutions and brands to launch, automate, and scale financial services from a singular solution. Having institutional clients in domains like wealth management, banking, credit, and insurance, Additiv’s technology allows businesses to expand their own offerings and introduce third-party products and services to their customers without having to replace core systems.
In early 2026, Additiv launched a new dedicated solution to help Germans navigate planned reforms to the country’s pension scheme. The reform calls for a new state-subsidised retirement investment account (Altersvorsorgedepot) that is offered digitally as a simplified, standardised solution, Standarddepot. Millions of legacy pensions (so-called ‘Riester’ contracts) will be migrated to the new pension product, creating new urgency for institutions that seek to attract or simply retain these customers,” the venture noted.
“This reform marks a genuine paradigm shift for German private pensions. For the first time, capital market-based products are sitting at the heart of state-subsidised retirement savings. Institutions that are now establishing scalable digital infrastructure will secure long-term customer relationships—and with millions of Riester contracts up for migration, the window to act is open,” added CEO Nils Frowein.
