Open Horizons Project Final Call 2026: up to 55,000 EUR for women-led early-stage deep-tech and digital startups

Open Horizons Project Final Call 2026: up to 55,000 EUR for women-led early-stage deep-tech and digital startups

The Open Horizons project has published the third and final open call (OC#3), targeted at women-led startups in Europe that are in early commercial stages and operating in digital or deep-tech fields. As of 18 May 2026, the status is open, with a submission cutoff on 19 May 2026 at 17:00 (CEST). The page is a direct official call page from EISMEA, which is part of the Horizon Europe support structure.

At-a-glance details

What this opportunity is and what it is not

This is not a standard equity investment program and not a large-scale R&D grant with open-ended project budget lines. It is a staged equity-free support mechanism designed to test and pilot startup concepts in a short operational window. The call explicitly supports early-stage startups, defined as 6 months to 6 years old and with limited prior equity raise, which strongly indicates that the cohort is meant for teams still searching for a stronger go-to-market and technical path.

The program’s model is built around selected startups progressing through two phases:

• Inception Stage: early-stage acceleration and feasibility validation.
• Piloting Stage: short pilot collaboration with corporate partners.

Funding is milestone-based:

• 10,000 EUR after Inception Stage,
• 20,000 EUR after mid-term pilot review,
• 20,000 EUR after successful pilot completion,
• 5,000 EUR after participation in final Demo Day.

The total cap per startup is 55,000 EUR. The call also says up to 16 startups enter Inception and up to 7 move into Piloting. It is therefore a selective funnel with explicit attrition.

This means you should not think of it as a single large grant award at signing. The value is in structured support tied to measurable checkpoints and corporate traction.

Who should apply and who should not apply

Given the constraints, this opportunity is best for:

• women-led startups with a strong problem definition and clear industrial relevance,
• teams operating in digital or deep-tech sectors,
• ventures that can move from concept to pilot quickly,
• founders who need structured first-stage support and pilot market validation,
• teams comfortable with milestone reporting and timeline-bound execution.

It is not a good fit if:

• the company is older than six years or already beyond initial seed traction stage,
• equity raised is above 1,000,000 EUR,
• the founding team does not meet the women-led ownership and management gate,
• the company does not fit digital or deep-tech domains,
• the team is looking for long, multi-year unconditional funding with little operational accountability.

A key point: the call page does not advertise broad national geographic categories outside the EU ecosystem. If your team is outside EU or associated countries, this is generally out of scope.

Why the “third and final call” wording matters

The call page calls this the last opportunity in the Open Horizons project timeline. In practical terms, this changes planning strategy:

1. There is limited runway left for multiple application tries.
2. Reviewers are likely to prioritize teams that are immediately scalable in pilot conditions.
3. Time spent on polishing eligibility and deadlines must be prioritized before the short window closes.

For teams that clear screening, selection into this cohort can be meaningful because you access not only funding but also a defined pathway: mentorship, testing arrangements, corporate matching, and visibility at final Demo Day.

Eligibility interpretation from the published rules

The call defines a hard gate set. Here is a practical interpretation:

• Country and legal basis is strict: EU or Horizon Europe Associated Country.
• The entity must be an autonomous SME.
• Age and financing conditions are objective and should be checked before submission; if even one fails, the application is expected to be rejected early.
• Women-led criterion is explicit in control and ownership terms.
• Corporate challenge alignment must be demonstrable. The page lists 12 challenges and this is effectively where reviewers will anchor novelty and feasibility.

Use this eligibility to pre-screen:

• If your legal setup includes a holding structure outside EU with operations inside, verify whether the applied applicant entity itself clearly meets base status.
• If you have raised capital, ensure a clean capitalization narrative that supports the under 1,000,000 EUR condition.
• If founder shareholding is split across a complex structure, present supporting documents (equity table, cap table, signature rights, board terms) in the application package.

Corporate challenge scope and proposal positioning

The call page lists challenge themes such as AI engineering, enterprise AI assistants, secure model exchange, energy efficiency, and industrial optimization. That indicates this is less a “general entrepreneurship call” and more a problem-match filter.

Your proposal should therefore:

• state one challenge category clearly,
• map your solution to a measurable pain point,
• describe how your pilot will produce observable signals by the end of the 5-month stage,
• avoid broad claims without evidence of how pilot outcomes can be measured.

A strong application usually frames:

• baseline state (what happens without the project),
• intervention (what the startup changes,
• success signal (pilot KPIs),
• customer or corporate value (who benefits and how).

The strongest proposals do not promise maximum market size in text only; they show a credible short path to one successful pilot outcome.

Application process and practical submission sequence

The official page is short on process steps, but it does provide two crucial mechanics:

• applications must be submitted exclusively via Sploro;
• the call is part of Horizon Europe and linked to Open Horizons project pages.

Recommended sequence (before 19 May 2026):

1. Verify all eligibility gates first using the published criteria.
2. Pick one challenge area and align your technical story to it.
3. Prepare a one-page core narrative:
   • problem,
   • solution,
   • why this pilot now,
   • milestones for each tranche.
4. Prepare finance summary for 55,000 EUR total cap; include spending logic but avoid rigid budgets with unsupported assumptions.
5. Upload and dry-run submission on Sploro to check field formatting, attachments, and file-size limits.
6. Submit early to reduce technical risk; leave time for corrections.

Because it is open on Sploro, document naming, language quality, and structured headings become part of pre-selection quality.

Required evidence and materials reviewers look for

Since this is an evidence-driven selection window, you should deliver:

• proof of eligibility (entity, legal status, age, equity threshold, founder criteria),
• a concise technical description tied to the selected challenge,
• clear timeline for an Inception and pilot path,
• direct indicators of feasibility and team capability,
• a realistic pilot execution plan with deliverables matched to the four funding tranches.

Avoid submitting long narrative-only descriptions without practical sequencing. For this type of program, clarity beats volume. This is especially important because this is a one-stage deadline: all eligible submissions are scored together against fixed criteria and reviewers have limited time for interpretation.

Common mistakes and avoidable disqualifiers

• Submitting outside Sploro or missing mandatory fields.
• Treating ownership and cap table conditions casually.
• Describing deep-tech features without showing pilot feasibility in 5 months.
• Listing every challenge theme instead of committing to one.
• Over-promising budget without showing what can be achieved within program support.
• Using corporate problem statements that are generic and not specific to your stage and team.

If this sounds strict, that is by design. Cascade-funding tracks are capacity filters first and mentoring tools second.

Review style and expected decision lens

The call page hints at an evaluation chain including screening, red-flag checks, independent expert review, interview, then final selection. That means scoring is likely a mix of objective and qualitative criteria:

• objective compliance with all hard requirements,
• problem-solution fit to one challenge,
• quality of pilot design,
• team readiness and women-led governance evidence,
• quality of execution logic.

Because results are announced later in the year, teams should prepare for response handling even after submission:

• if selected for Inception, prepare rapid onboarding artifacts,
• if selected for Piloting, secure pilot partner coordination early,
• if not selected, use feedback patterns to strengthen readiness for other EIC or national programs.

FAQ

Is this still open now?

As of the checked date, the call page status is open. Always verify directly again before submission.

Can teams with venture-backed history apply?

Teams can apply if they meet the equity threshold and age limits; this can include early VC-backed startups if capitalization remains within limits.

Is the 55,000 EUR guaranteed?

No. Funding is milestone-based and includes step-based disbursements tied to progress. Completion quality determines continuation.

Can this be used to fund salaries and company expenses?

The call includes support packages distributed by milestone, but exact eligible expense details are in linked program documentation; this page should be read together with official guidance.

How competitive is it?

The final-call positioning (only 16 to 7 progression in stages) indicates high competition and a narrow funnel.

Preparation checklist before submission

Use this list as a final readiness pass:

1. Eligibility matrix completed and reviewed by a co-founder with legal/commercial responsibility.
2. Corporate challenge selected and mapped to a measurable pilot.
3. Milestones and risks documented per tranche.
4. Split timeline into Inception and pilot phases.
5. Confirm all documents in required format and language.
6. Dry submit via Sploro and test.
7. Submit at least 24 to 48 hours ahead of deadline.

The opportunity is narrow but real in funding terms for women-led early-stage teams. Most teams fail not because their idea is weak, but because they misread the operational requirements. The best submissions are the ones that treat this as an execution competition in two sprint windows, not as a broad funding request.
