QurAlisQurAlis Corporation is a Cambridge, Massachusetts biotechnology company developing precision medicines for amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD) and other neurodegenerative diseases. Its research combines disease genetics, patient-derived stem-cell models and biomarkers with small-molecule and antisense oligonucleotide therapies. Its FlexASO platform develops splice-modulating antisense compounds; clinical programmes include QRL-201 and QRL-101. The company is relevant to neuroscience and advanced biotechnology; no unsupported artificial-intelligence claim is made. The current own team page, modified September9,2026, publishes seven executives, nine board members, eight scientific advisers and five clinical advisers, representing28 distinct people. Kasper Roet serves as CEO and board member; Kevin Eggan and Clifford Woolf also have explicit founder affiliations. An obsolete hidden Jinsy Andrews modal is not treated as current roster membership. Manoj Malhotra is the current CMO, superseding older Doug Williamson announcements. One published adviser modal incorrectly reuses Manoj’s photo; Ammar Al-Chalabi’s authentic original portrait is instead verified against his own King’s College London biography. Shared people’s biographies, portraits and external affiliations are preserved. Primary financing includes an undisclosed-size seed round reported April5,2018, USD42million SeriesA announced May13,2020, and USD88million SeriesB closed March9,2023. Cumulative totals are not additional rounds. A June3,2024 Lilly agreement combines an upfront USD45million licensing payment with a separately stated equity investment of undisclosed amount; the licensing payment and potential USD577million future milestones are not equity fundraising. ALS Association research awards are recorded separately from private investment. The2017 Amgen Golden Ticket provided laboratory space and services, not an inferred cash financing. SEC filings identify the Delaware corporation, incorporated in2016 (CIK1811817). Separate convertible-promissory-note offerings reported USD5million securities sold in2022 and USD19,952,387 in2025; their targets of USD10million and USD24,921,734 are not completed raises. The cash fields remain unquantified pending reconciliation of note conversions with later equity financing. SeriesA andB SEC snapshots describe those same offerings and are not extra rounds. The March2026 corporate presentation explicitly described SeriesC funding as pending.Cambridge, Massachusetts, United States

Ramen VRRamen VR is the San Francisco game-development and AI-agent company founded in 2019 by Andy Tsen and Lauren Frazier, operating at ramenvr.com through TribeVR Inc., a Delaware corporation (SEC CIK1788637). It was part of Y Combinator Summer2019 and originally developed the multiplayer VR game Zenith: The Last City. Its current Aura product is an AI agent integrated with Unity and Unreal Engine, including code and Blueprint work, editor operations, memory and verification/playtesting workflows. The March2026 acquisition of Coplay brought Unity AI tooling and its Unity MCP integration into Aura; the June2026 acquisition of Flopperam brought additional Unreal AI tooling and co-founder Chris Gong as Senior AI Engineer. Acquisition prices are undisclosed. Its September2026 Aura1.0 issuer release describes Anthropic Claude-based agents and Mac/Windows support. Productivity and game-market-coverage figures are company claims rather than independently established benchmarks. Current and historical named team affiliations are separately qualified; Lauren Frazier-Silva now identifies herself as founder of Silvermoon and is not presumed to remain current CTO. Ramen VR announced a USD35M SeriesB on17March2022 led by Anthos Capital and Dune Ventures with Makers Fund participation and personal checks from Andrew Chen and James Gwertzman, not an automatically inferred Andreessen Horowitz firm check. SEC filings separately document a single2021 offering with USD10,000,015 sold, and a2022 exempt-offering filing whose USD27,499,969 scope differs from the issuer’s35M headline; these are not summed into duplicate cash rounds. The2019 Zenith Kickstarter’s USD280,075 is pledged rewards crowdfunding, not venture equity. This company is distinct from ramennetworks.com and other Ramen businesses.

The company announced a $2.7 million seed round in June 2025 and an $8 million financing co-led by Voyager Capital and Access Venture Partners in September 2026. The September SEC filing reports a different equity-sold amount of $10,835,253, without explaining its relationship to the announced $8 million; it is retained as a disclosure rather than another financing. Rapta also received a $50,000 Space Florida Accelerating Innovation Award in June 2025 and was awarded $110,500 in investment commitments at the October 2025 Bend Venture Conference.

ReadilyReadily is a San Francisco healthcare-compliance AI company building a unified platform for regulatory research, policy management, delegation oversight and audits. It links requirements, policies, contracts, reports and case files, analyzes audit evidence, identifies policies affected by regulatory changes and drafts revisions for expert review. It serves health plans and providers, including Medi-Cal managed-care organizations. Reported time, cost and audit-coverage improvements are company and investor case-study claims, not independently verified clinical outcomes. Edward Tiong is co-founder and CEO, and Wei An Wang is co-founder and CTO; those are the two active founders named by Y Combinator. Its directory reports20 team members but does not name the full staff. CHCF reports a2023 founding and YC records Summer2023 participation, while YC’s current Founded field says2024; the inconsistent2024 field is retained as a source discrepancy rather than treated as a separate company or financing event. California Health Care Foundation reports a USD1million program-related investment awarded in June2026. Its exact day, security instrument, round stage, terms and disbursement status are not disclosed. The company explicitly names Y Combinator, Define Ventures and CHCF as backers; SUTD’s own Venture Innovation Fund also lists Readily in its portfolio, linking the former readily.co domain that now redirects to readily.ai. No standard accelerator ticket or undisclosed seed total is inferred. Readily is relevant to healthcare AI and regulatory automation; reviewed sources do not establish a neuroscience therapeutic or neural-interface business. It is distinct from Swedish Readily Diagnostics, government-service company Readyly, Read AI and Indian Readily Solutions. Y Combinator’s August2024 launch and Ihsaan Patel’s own launch post also identify Patel as a co-founder alongside Edward Tiong. That historical affiliation is retained separately from the current active-founder list; no current Patel CEO office or departure date is inferred.San Francisco, California, United States

RealizedCareRealizedCare is the acquired immersive digital-therapeutics business built around BehaVR, OxfordVR and Fern Health. Its products combine virtual reality, cognitive behavioral approaches and biopsychosocial care for chronic pain and behavioral-health conditions, with AI-supported care triage described by its acquirer. Historical BehaVR was founded in 2016 and filed as BehaVR LLC, later BehaVR Inc. OxfordVR combined with BehaVR alongside a USD13M Series B in December 2022; Fern Health joined the platform under the RealizedCare brand in 2023. These historical issuer and acquisition boundaries are qualified rather than treated as interchangeable independent funding recipients. XRHealth announced the acquisition in February 2025 and appointed founder Aaron Gani general manager of XRHealth US. A September2026 buyer SEC filing identifies the seller as BehaVR Holdings Inc. (RealizedCare) and reports stock consideration for an asset purchase. That noncash transaction and a separately filed XRHealth loan are not represented as new RealizedCare financing. Current standalone leadership could not be verified from the inaccessible current company site; attached public leadership and scientific advisory affiliations are expressly historical or source-dated. Verified financing includes a partial USD500K debt securities sale disclosed in2018, an adviser-confirmed completed USD10M2020SeriesA (with an earlier partial SEC disclosure qualified), and an actual USD13M2022SeriesB. Funding targets, undisclosed additional financing reported retrospectively, contingent licensing payments and academic research budgets are not added as cash raised. OxfordVR’s separate precombination capital history remains a distinct issuer research task. The 2021 Sumitomo digital-therapeutics licensing programme is qualified as a commercial development arrangement.

RebrainRebrAIn is a French medical-software company developing supervised AI-based, patient-specific MRI processing and brain-targeting tools for functional neurosurgery. Its legal issuer is Rebrain SAS, SIREN892511866, active since January1,2021 according to the French government register; its US operating affiliate Rebrain US Corp is identified separately on the same corporate website. Neurosurgeon Emmanuel Cuny and Inria applied-mathematics researcher Nejib Zemzemi co-founded the University Hospital of Bordeaux/Inria spin-off following academic research. Its OptimMRI software processes preoperative DICOM MRI images and helps qualified clinicians visualize and localize anatomical structures, including STN/VIM, alongside other clinical methods for neurosurgical planning. FDA records confirm ClassII 510(k) clearance K230150 on July21,2023 and OptimMRI(v2) K242054 on August12,2024; these are software device clearances, not drug approvals, autonomous treatment authorization or independent proof of clinical benefit. The company also reports European CE marking, with an independently retrieved CE certificate not available in this audit. Its current public directory identifies David Caumartin as CEO, Emmanuel Cuny as CMO/board president and Nejib Zemzemi as CSO/CTO, a strategic board and nine scientific/medical advisers. The statutory register separately identifies David Caumartin as Président de SAS and Cuny/Zemzemi as Directeurs Généraux. Additional people in its January2025 team announcement are recorded as dated affiliations where current operating titles cannot be confirmed. A completed EUR3.7M seed financing announced March18,2024 was led by Karista, joined by NACO and unnamed existing investors. Karista’s portfolio year2023 is not treated as a second priced cash event.

ReMoniReMoni is the Danish AI and sensing technology company REMONI A/S, identified by its own website as CVR35212124, based in Skanderborg. It combines patented non-invasive clamp-on sensors with statistical models and artificial intelligence to monitor electricity, heating, cooling and water and optimize resource use in buildings and industrial systems. Products include Predictive Heat Optimization, EnergyXplorer and monitoring/control platforms; its research includes power-quality analysis, district heating and digital twins. The company website describes operational founding in2014, while the historical investor article says2013; this discrepancy is not resolved into an exact legal incorporation date. Its contact page separately identifies ReMoni Danmark A/S CVR39326345 and Romanian ReMoni Technologies RO S.R.L.; those operating entities are distinguished from this company profile. The public directory publishes leadership, commercial staff and three directors with authentic named photographs, but has conflicting leadership layouts: Anders Hjortsholm is listed as CCO while another block calls Anders Steen Mortensen CCO rather than Head of Building Optimization. Both published affiliations are retained with that uncertainty, without invented tenure dates. Capnova was a historical shareholder and announced its exit in2020 alongside Kenneth Iversen's reported DKK20M investment; the source does not separate secondary acquisition proceeds from new issuer cash. A September2020 announcement distinguishes an EUR480,000 Innobooster award from Kenneth's prospective EUR1,350,000 matching private investment; grant disbursement and completion of the matching investment are not established. CORDIS separately records REMONI A/S as a beneficiary of grant958600 with EUR637,087.50 net EU contribution, not the entire consortium's EUR1,708,193.75 grant or EUR2,239,943.75 project cost. Awards, future commitments and those aggregate budgets are not recorded as completed equity cash.Skanderborg, Denmark

reMYNDreMYND NV is a clinical-stage Belgian biotechnology company developing oral small molecules for neurodegenerative diseases. Founded in 2002 as a KU Leuven spin-off, it is registered under Belgian enterprise number BE0476.910.101 and is based at Gaston Geenslaan 1, Leuven. Its Alzheimer’s programme investigates septin modulation to restore calcium homeostasis and synaptic function. Lead candidate REM392 is investigational; the September2026 announcement plans a Phase1b patient study for early2027. Earlier REM127 Phase2a findings and exploratory AI digital-twin analyses do not establish approval or a proven cure. The Huntington’s candidate REM949 and mitochondrial-dysfunction discovery work remain development programmes. In March2025, reMYND sold its contract-research business to InnoSer to focus on proprietary drug development; older homepage CRO text is superseded by that transaction announcement. CEO Floor Stam was appointed in September2024; Gerard Griffioen is CSO. The current public directory names five operating leaders/advisers and seven board members, with Floor appearing in both groups. Former chair Johan Cardoen died in2025. KU Leuven’s September2026 interview separately confirms Joris Winderickx remains a scientific adviser after leaving the founding board. Completed announced equity comprises EUR12M SeriesB in December2018 and an additional EUR12M second close announced January21,2021; EUR24M is their aggregate, not a third raise. Investor PMV also documents an earlier convertible loan and a2022 syndicate financing with undisclosed amounts. On September21,2026, the company announced EUR3.5M strategic support from ADDF for REM392; ADDF project20731238 reports USD4,122,340 funding over September15,2026–March15,2028. These are source-specific representations of one programme award, not two cash raises. Instrument, disbursement and paid equity are unpublished, so structured cash amounts remain unknown. VLAIO/IWT and Michael J. Fox Foundation historical grant support is documented separately from equity; unspecified grant totals, license payments and the CRO sale price are not invented. BNP Paribas Fortis Private Equity’s own original credentials separately document two earlier equity investments inSeptember2009 andMay2016, corroborating the current bank portfolio’s2009 entry. These historical financings have undisclosed company totals, individual tickets, exact closing/announcement days and priced-series stages. They are distinct from the later2018 and2021 SeriesB closes; no parentbank, subsidiary or advisor-only cash duplication is inferred. The official ARKimedes-Fonds year-end2009 report additionally identifies Fortis Private Equity Arkimedes as the historical investing vehicle and records EUR750,000 cumulative investments in reMYND through December31,2009. This cumulative portfolio history is not assigned as the individual September2009 check or a further company round.

Rivus BatteriesRivus Batteries is the Gothenburg company Rivus AB, developing aqueous organic electrolytes for stationary flow batteries. Its chemistry stores energy using organic molecules, water and salts rather than critical-metal electrolytes such as vanadium, with the goal of supporting long-duration renewable-energy storage and more resilient supply chains. It designs the electrolytes to work with existing commercial flow-battery hardware and industrial chemical production, rather than requiring proprietary battery stacks. Its commercialization effort began in early 2023, following research at Chalmers, the University of Turku and the Technical University of Denmark. The company is advancing chemical scale-up, stack testing and customer pilots during 2026–2027; its 2028 large-scale deployment objective is a target. Lower costs, safety and performance advantages are company development claims, rather than independently proven outcomes of widespread commercial deployment.

Riyadh Valley CompanyRiyadh Valley Company (RVC) is the commercial knowledge-economy and strategic-project investment arm of King Saud University in Riyadh, Saudi Arabia. Its own institutional history records establishment in2010 by Royal Decree No.116 dated13/4/1431AH. It invests locally and internationally in growth-stage businesses to generate financial and strategic returns and connect university research and capabilities with commercial investment. The public royal-decree history establishes its university-company identity; an exact commercial-registration number and share-capital amount have not been independently verified. It is represented as a corporate Company investor, rather than an external private venture-fund manager. The venture portfolio spans biotechnology and healthcare, information and communications technology, sustainable resources, fintech, logistics and education. RVC also backs third-party venture funds, including deep-tech Abies Ventures FundII, and develops university-land projects for research, education, healthcare and other uses. Those investee funds are not RVC-managed fund closes. Its direct neuroscience relevance is the company’s own March25,2021 announcement of an investment in Australian Global Kinetics PtyLtd, developer of the Personal KinetiGraph objective Parkinson’s movement-monitoring system; ticket, stage and exact paying vehicle are unpublished. Corporate capital, university land, programme budgets and third-party fund targets are not asserted as new LP-fund cash raises. No RVC-managed closed LP vehicle has been verified. All seven currently published board members and nine published committee appointments are represented, with overlap retained as separate governance roles. CEO Khalid Al-Saleh is last explicitly confirmed by RVC in its September25,2025 investment release and by the university’s own industrial-engineering biography; continuing tenure beyond the last dated confirmation is qualified. This is the complete accessible named governance roster plus that source-confirmed executive, rather than a claimed census of private employees. Ten distinct authentic own-governance portraits and Khalid’s authentic university portrait are recorded. The website incorrectly repeats the same asset for Andrea Longhi, Faisal Alyemni and Sara Alhusaini; these three images are withheld pending identity-confirmed portraits. Exact director appointment dates and unpublished broader biographies remain unknown. The earlier May2025 chairman is not substituted for the current published chairman.Riyadh, Saudi Arabia
