Rilemo has crossed the line that historically separates a laboratory project from a manufacturable medical device. The hardware architecture is frozen and industrialised, the manufacturing partner is engaged, the pre-clinical validation portfolio spans in-vitro phantoms, ex-vivo bovine bone, ex-vivo human cadaver, and in-silico digital-twin simulations on human heads, and the regulatory documentation set required to enter the certification pathway has been delivered.
The Seed round funds the company through the three remaining gates that separate Rilemo from market entry: the first-in-human clinical investigation, CE marking under MDR Class IIa, and the first commercial deployments to research and clinical accounts.
Where Rilemo stands today (April 2026)
The last twelve months were the most operationally intense in the company’s history. Engineering risk, traditionally the dominant uncertainty for a hardware medical device at this stage, has been substantially closed. The most material achievements, several of which were not yet planned at the time of the SAFE round, are summarised below.
Industrialised hardware architecture frozen. The full Head Unit, Bedside Unit, and Calibration Phantom have been redesigned for manufacturability, with per-PCB specifications, BOM, and supplier audit completed.
CDMO partnership with Creanova initiated, which lead to the creation of a complete documentation package including User Needs, System Requirements, GSPR, Hazard Traceability Matrix, Usability and Mechanical Requirements, Software Architecture Review (IEC 62304 Class B), Design Records Review (ISO 13485), Hardware Architecture Review (IEC 60601-1), Preliminary Test Strategy, and Information Checklists.
First peer-reviewed validation against clinical CT ground truth completed in 2025 in collaboration with IRCCS Sant’Ambrogio Galeazzi Hospital (Milan), demonstrating µL-scale fluid detection in biological tissue with statistically significant correlation against directly measured volumes (Pearson r = 0.78, p = 0.037). The paper, co-authored with Prof. Luca Maria Sconfienza (Head of Diagnostic and Interventional Radiology at IRCCS Galeazzi-Sant’Ambrogio), is currently awaiting publication.
Anthropometric fit validated across 18,431 Monte Carlo head simulations spanning 5th to 95th percentile populations and four cephalic-index categories, confirming that the Head Unit accommodates the full target patient population without compromising contact quality or signal integrity.
In-silico validation on a 30-head digital-twin dataset completed. The campaign uses anatomically realistic head models from the IT’IS Foundation Population Head Models (PHM) repository, dielectric tissue properties drawn from the IT’IS Foundation database with literature-guided variability, and haemorrhagic and ischaemic lesion geometries derived from published clinical literature.
Ex-vivo human cadaver imaging campaign at the Trecchi Human Lab (Cremona, Italy, May 2025) completed with positive results across all samples, validating the device on real human tissues in a final clinical environment, with direct involvement of neurosurgeons and clinical staff.
300+ structured clinician interviews completed across Europe and the United States between 2023 and 2025, identifying point-of-care imaging for acute neurological conditions as the most validated commercial opportunity by a significant margin (see Market Overview).
Milestone calendar
The calendar below is aligned to the Go-to-Market and Financial Plan . Dates are stated explicitly with the assumptions they depend on, so that each milestone can be stress-tested independently.
Q2 2026 - Design freeze and engineering build at Creanova. The industrialised architecture moves from documentation to first physical articles built under the CDMO’s quality system. Pre-compliance bench testing begins in parallel.
Q2-Q3 2026 - Expanded ex-vivo human cadaver campaign. A second cadaver campaign extends the May 2025 dataset, increases the number of imaged samples, and produces the structured pre-clinical data package that supports the clinical investigation submission. This work also reduces the patient count required for the clinical investigation, compressing the overall certification calendar (see Clinical Validation).
Q3 2026 - Compliance test campaigns begin. EMC pre-scans and electrical safety pre-tests under IEC 60601-1 and IEC 60601-1-2 are run first because they are the highest-risk failure modes in the compliance pathway. Biocompatibility testing on patient-contacting materials runs in parallel.
Q4 2026 - First research-device deliveries to selected universities, IRCCS institutions, and independent research centres, in line with the Financial Plan.
Q4 2026 - Clinical investigation protocol submitted to Ethics Committees. Non-inferiority design against CT for the defined acute neurological use case, with primary endpoints aligned to the regulatory and clinical guidance.
Q1 2027 - Compliance certification testing complete and clinical investigation begins. With ethical approvals in hand and the full safety and EMC dossier closed, patient recruitment begins at the lead investigation site.
Q2 2027 - Technical file consolidation and Notified Body slot active. The full MDR Annex II/III technical documentation is consolidated, drawing on the deliverables already completed, the compliance test reports, and the early clinical investigation data.
Q2 2027 - Submission to the Notified Body under MDR Class IIa, Rule 10 (hardware) and Rule 11 (software). Submission timing is set to allow the device to be CE-marked and on the market in the second half of 2027, in line with the Financial Plan revenue trajectory and Go-to-Market .
H2 2027 - CE marking obtained and first commercial medical-device sales begin. Forty medical-device units are planned in FY27 in line with the Financial Plan, focused on innovative private hospital groups and IRCCS centres in Italy where pre-existing relationships have been developed during the pre-clinical phase.
The internal logic of this calendar is the 2027 CE-marking gate, which requires the clinical investigation, the compliance testing, and the technical file to all complete on schedule. The next section explains how each of these dependencies is being de-risked.
Risk register and mitigations
The path to CE marking involves a small number of execution risks that are actively managed. Each is acknowledged below, together with the mitigation already in place or planned.
Risk | Why it matters | Mitigation in place |
Clinical study delays | The first-in-human investigation, study design, ethics approval, patient recruitment, and data quality, represents the most operationally complex workstream on the path to CE marking. | • The founding team includes a practising emergency physician. • Clinical and regulatory advisors are already engaged. • Pre-existing relationships with IRCCS-class institutions were developed through the structured clinical interview programme and the cadaver campaign. • The expanded ex-vivo dataset reduces the required patient count. • Documentation groundwork with the lead investigation site is already underway. |
Regulatory execution and certification timeline overrun | Notified Body capacity under MDR is constrained, and review timelines can add months to the certification calendar if the submission is not prepared and sequenced correctly. | • Preliminary discussions with the Notified Body have already begun. • A regulatory advisor is engaged and guiding the strategy. • Technical documentation is being structured progressively against MDR Annex II/III requirements in collaboration with the CDMO, so that the submission package is built continuously rather than reconstructed at the end. |
Compliance test failure | A single failure in EMC, electrical safety, or biocompatibility can introduce a redesign loop measured in months. | • Pre-compliance pre-scans are planned in Q3 2026 ahead of formal testing to identify and address failure modes early. • EMC and electrical safety risks have been specifically addressed during the hardware architecture review. • Biocompatibility material selection was made on the basis of ISO 10993-1 evaluation. |
Manufacturing ramp-up delays | Moving from prototype to manufactured device can surface unexpected yield and supply chain issues that delay first deliveries. | • Creanova engaged from the design transfer stage rather than after design freeze, ensuring manufacturability is built into the product rather than retrofitted • Per-PCB specifications, BOM, and supplier audit already completed. • First production batch sized to absorb both the clinical investigation and the first commercial year. |
Competitive response from established players | Large medtech players could accelerate their portability roadmap in response to Rilemo's market entry, reducing the time available to build a defensible market position. | • Rilemo's core advantage is not hardware alone but the combination of proprietary AI algorithms, training data, and image reconstruction software, assets that require years of focused R&D and proprietary training data to replicate. • The IP portfolio creates a legal moat around the key innovations. • A champions-first go-to-market strategy is designed to build switching costs and clinical loyalty before larger players can respond at scale. |
Clinical adoption resistance | Introducing a new imaging modality requires behavioural change across multiple specialties each with different workflows, decision criteria, and institutional dynamics. Adoption can be slow even when clinical evidence is strong. | • The go-to-market strategy deliberately targets clinical champions across neurology, neurosurgery, emergency medicine, and radiology as first adopters, leveraging peer influence to drive broader departmental adoption. • Pre-existing relationships with IRCCS-class institutions provide credible reference sites that reduce perceived adoption risk for subsequent buyers. • The device requires no patient preparation, no shielded room, and no specialised training minimising the behavioural change required at point of care. |
Beyond CE marking
CE marking is the gate this round is designed to reach, but not the end of the plan.
From FY27 onward, Rilemo will be a certified, commercially active medical device company, with an installed base growing across European hospital departments and a compounding recurring software revenue stream, as detailed in the Financial Plan section.
The same regulatory foundation extends across ambulances, residential care, and pre-hospital settings, consistent with the phased market entry described in Go-to-Market.
Beyond Europe, the United States represents a defined next step, with a regulatory pathway already mapped in Regulatory Pathway.
The full scale of the opportunity, spanning additional geographies, adjacent care settings, and a large structurally underserved global market is documented in Market Overview.
