Company profile
researched Aug 2026Sekkari is an early-stage UK technology company operating under the registered entity SEKKARI LTD (company number 16803645), incorporated in England on 22 October 2025 with a registered office at 66 Paul Street, London EC2A 4NA. Its declared nature of business at Companies House covers business and domestic software development (SIC 62012) and other research and experimental development on natural sciences and engineering (SIC 72190), consistent with a hardware/deep-tech research orientation.
Publicly visible recruitment activity indicates the company is building a founding technical team in silicon photonics. Listed roles include "Founding Photonics Engineer" and "Founding Silicon Photonics IC Engineer for Autonomy," both full-time and based in London, the latter title explicitly referencing autonomy applications. Beyond company registration details and job listings, little verifiable public information about products, customers, or commercial traction was available in the sources reviewed. One aggregator profile describes the company in generic terms as a UK "scale-up" of 50-100 employees providing software development, data analytics and cloud computing services; this description conflicts with the company's photonics-focused job listings on the same page and with its recent 2025 incorporation, so it is not treated as reliable.
Traction
No revenue, customer, product-shipment, or funding figures appear in the available public sources. The only observable activity is company registration and recruitment for founding technical roles in London [0][1].
Latest developments
As of the sources reviewed, Companies House lists the company as active with no filings yet due, and the company was recruiting for two founding photonics engineering roles in London, with postings refreshed within the prior week [0][1].
▸Full profile — technology, go-to-market, geography, history, risks & controversies
Technology
Public job listings point to a silicon photonics focus, with openings for a Founding Photonics Engineer and a Founding Silicon Photonics IC Engineer for Autonomy, suggesting work on photonic integrated circuits [1]. The company's registered SIC codes cover software development and research and experimental development in natural sciences and engineering [0]. No technical specifications, chip architecture details, or performance benchmarks were disclosed in the available sources.
Go-to-market
The "for Autonomy" designation in the company's engineering role titles indicates an intended application area in autonomous systems [1]. No named customers, design partners, or served market segments appear in the sources.
Geography
The company is registered in England with a London registered office at 66 Paul Street, EC2A 4NA [0], and its advertised engineering roles are located in London [1]. No other locations are documented.
History
The company was incorporated at Companies House on 22 October 2025 as SEKKARI LTD, a private limited company registered in England [0]. Its first accounts are due to be made up to 31 October 2026 and its first confirmation statement is dated 21 October 2026, indicating no annual filings had yet been made at the time of review. Shortly after incorporation, the company began publicly advertising founding engineering positions in London [1].
Risks & controversies
No litigation, regulatory action, or controversy involving this company appears in the sources. Note that at least one aggregator profile presents an inconsistent characterisation of the company (a 50-100 employee "scale-up" offering software, data analytics and cloud services) that does not align with the entity's 2025 incorporation date or its photonics hiring, indicating unreliable third-party data [0][1]. Several retrieved documents concern unrelated organisations with similar names or unrelated subject matter and were excluded.
