H2O Consulting is a Belgium-based data technology consultancy serving clients globally. It is not positioned as a traditional SaaS product or developer tools platform, but rather as a professional services provider focused on data integration and digital transformation. Its website tagline is βMake data simple again,β with a core focus on NoSQL, semantic technologies, MarkLogic, unstructured documents, and data technology stacks such as XML/JSON/RDF.
Based on the site content, its services cover the data lifecycle from storage to delivery, including strategy definition, data storage and consumption architecture, scalability, flexibility, and modeling. It can also provide support from analysis and architecture through to implementation. Its technical scope is clearly centered on NoSQL, Semantics, XML, JSON, HTTP, RDF, MarkLogic, XSLT, XQuery, XPath, EXPath, and related areas. For organizations using MarkLogic, XML databases, the semantic web, or unstructured document systems, this experience is highly relevant.
The background of CTO Florent Georges is the main credibility signal disclosed on the website. He has participated in conference talks and book reviews related to XML, XSLT, XQuery, EXPath, SOA, and other topics, and is an invited expert in the W3C XSL Working Group, a member of XML Guild, and a member of the MarkLogic SuperNodes expert group. The site also provides technical articles, publications, and resources such as the eXist collection management library, indicating a certain level of accumulated expertise in the XML and MarkLogic ecosystems.
The website does not disclose its pricing model, consulting rates, service packages, contract terms, or payment methods, so it is not possible to assess procurement cost or value for money. It appears to be a highly specialized consulting service, requiring project-based discussion via email at [email protected]. There is also no visible API, SDK, self-hosted software, online console, or standardized developer product documentation.
Its strengths are its focused technical direction, especially for complex data modeling, XML/semantic technologies, MarkLogic, and unstructured document scenarios. It also has industry experience in banking, the public sector, telecommunications, publishing, and other fields. The drawbacks are that the official website provides limited information and lacks customer case studies, deliverables, team size, service SLA, and pricing transparency. If users are looking for a developer tool or cloud platform they can try immediately, it is not a good fit.
It is suitable for enterprise technical teams that already have complex data assets and need external experts for architecture reviews, MarkLogic/NoSQL implementation, or the evolution of XML/XQuery/XSLT systems. It is less suitable for individual developers who need low-cost self-service tools, ready-to-use SaaS, or full Chinese-language support. The site content does not provide information about access from China, and payment methods are also unknown. Domestic alternatives could include local data governance or data architecture consultancies, or going directly to professional services from vendors such as MarkLogic, MongoDB, and Neo4j.
