Brussels – 17 September 2025

Belgian scale-up SEQUESTO has raised € 2.5 million in growth capital from Newion and Smartfin, two of Europe’s most renowned B2B SaaS investors.
SEQUESTO streamlines the entire RFx process (RFI, RFQ, RFP, and tenders) with an AI-first platform and agentic workflows, enabling organizations to achieve more RFx business with the same team – faster, at scale, and with full governance.
SEQUESTO is active today in all major European markets and the United States, serving a diverse client base ranging from SaaS players to highly regulated enterprises.
The funding will accelerate SEQUESTO’s international expansion and strengthen its position as the market leader.

Smartfin and Newion announce a strategic €2.5 million investment in SEQUESTO, the Belgian scale-up redefining the way companies respond to tenders, RFIs, and RFPs. With its AI-first approach and agentic workflows, SEQUESTO automates nearly all repetitive, time-consuming, and error-prone tasks across the entire RFx cycle, structurally boosting tender teams’ efficiency and win rates.

The global market for RFP optimization software is growing rapidly, driven by the increasing number and complexity of tenders and the breakthrough of AI technology. For most organizations, responding to RFPs, RFIs, and other complex procurement procedures is still a highly manual, time-intensive, and frustrating process with high costs and relatively low win rates.

Where legacy players offer only incremental improvements, SEQUESTO fundamentally transforms the RFx process through deep use of innovative, advanced AI capabilities. This sets it apart from traditional competitors like Loopio and Responsive, who have dominated this segment for years.

The impact goes well beyond saving time: SEQUESTO systematically reduces content management costs, speeds up time-to-value, and demonstrably increases win ratios on complex bids.

Founded in 2020 by Patrick Dalvinck (CEO) and Evrard t’Serstevens (CTO), SEQUESTO has evolved from a Belgian start-up into an international growth company. Today, SEQUESTO operates in multiple European core markets and the US, serving customers ranging from fast-growing SaaS companies to highly regulated enterprises, including ISS Facility Services, ooDrive, and Barona. The team currently numbers sixteen and continues to grow.

“SEQUESTO delivers a holistic solution that unites orchestration and response development in one powerful platform, purpose-built for tenders. Where other tools are confined to niches, SEQUESTO supports the entire RFx cycle and is deployable across every sector and region,”

says Frank Claassen, Managing Partner of Newion.

With the € 2.5 million capital injection from Smartfin and Newion, SEQUESTO aims to accelerate its international expansion and solidify its position as the most intelligent AI RFP Response Platform.

“Tenders are strategically important for many companies, but the process is often slow, complex, and inefficient. SEQUESTO combines AI and automation to fundamentally redesign this process. At Smartfin, we invest in companies that build platforms which structurally improve efficiency,”

says Jürgen Ingels, Founding Partner of Smartfin.
