[1] Proposals with the same score were ranked according to the priority order procedure set out in the call conditions (for HE, in the General Annexes to the Work Programme or specific arrangements in the specific call/topic conditions). For HE, to determine the ranking for ‘Innovation actions’, the score for ‘Impact’ is given a weight of 1.5.
Summary of observer report:
The two independent observers were tasked by the EC services to follow the evaluation processes of call HORIZON-CL4-2026-04 with respect to their conduct, transparency, and fairness, and to provide recommendations for process improvement. This Observers’ Report consolidates their observations and recommendations. Based on the observed Consensus Meetings and Panel Meetings, the evaluation procedures for all topics were carried with transparency, efficiency, fairness, consistency, impartiality with homogenous criteria in compliance with the applicable evaluation rules for each stage of the selection exercise (Individual Evaluation, Consensus Meetings, Quality Check, Cross-reading, Panel Meeting and Final Ranking for funding). The evaluation processes were carried out in full accordance with the Horizon Europe evaluation rules and the provided Digital Europe Programme evaluation briefings. The Call with 12 topics received 312 proposals, where 5 were inadmissible, 17 ineligible and 0 withdrawn. The number of proposals per topic varied from 1 to 105. Proposals were evaluated by 218 experts, with a satisfactory gender balance (44,5% female; 55,5% male). The majority of experts were from EU Member States and a small number from associated countries. Sixteen invited experts declined due to conflict of interest or other reasons. In conclusion, the overall assessment of all submitted proposals were executed in full transparency and compliance with the Horizon Europe applicable rules in a fair and impartial manner to select the best proposals for funding according to the topics’ specifications and expected results. The observers’ conclusion is that the scientific evaluations have been carried out in a just, transparent, and unbiased manner based on the Horizon Europe evaluation rules.
We recently informed the applicants about the evaluation results for their proposals.

The overall expected outcome is a large selection of Open-Source solutions that will be organised under the Open Internet Stack framework built under WP 2025. This will address the needs of both supply and demand side of the rich and diverse eco-system of 3C European providers and verticals. This topic will stimulate the emergence at European and global scale of solutions that are:
Proposals should address one or several of the following technology areas:
Applicants should devise a plan for ensuring that the solutions are designed for efficient deployment, with pre-configured, modular components that facilitate integration by a wide range of users, including SMEs, public administrations, research and education and service providers.
Applicants should detail development, integration, testing, deployment, uptake and operation activities. Focus will be on Open Source solutions and their integration and adoption in vertical use cases, to ensure replicability of the results and portability in different areas.
Proposals are expected to demonstrate:
Applicants should detail any relevant previous projects on which the project will expand.
Applicants should detail their plan to creating synergies with other topics such as those in the WP25 Open Internet Stack, 3C, Virtual Worlds/Web4.0 as well as like-minded initiatives on the same solution perimeter.
Proposals should also detail their strategy for maintenance, cataloguing, marketing, communication as well as the relationship with to the “Open Internet Stack Support for Scale” topic.
Beneficiaries that intend to transfer ownership or grant an exclusive licence must formally notify the granting authority (i.e. DG-CNECT and HaDEA) before the intended transfer or licensing takes place and the granting authority may up to four years after the end of the action object to a transfer of ownership or the exclusive licensing of results.
Financial support to third parties
If applicants opt for financial support to third parties, they should primarily target calls towards internet innovators and adopters of Open Source technologies. Applicants should provide the programme logic for the third-party projects, managing the projects lifecycle, and provide the necessary technical and non-technical support: these tasks cannot be implemented using the budget earmarked for the financial support to third parties.
