revalu
Material data platform for the built environment, pairing a database of 45,000+ verified building materials with Kasper, an AI material advisor that answers questions on product and EPD data and runs early-stage life cycle assessments.
What is revalu?
revalu is a material data platform for the built environment, built by Berlin company Revalu Impact AG. It addresses a practical problem in construction: the environmental data needed to choose materials sits scattered across product pages, technical documents and Environmental Product Declarations, in formats that rarely line up. revalu gathers that information in one place and adds an AI layer on top of it.
The product is organised around three named parts. Database holds more than 45,000 verified materials, presented as harmonised, traceable and up to date, with lower-carbon alternatives surfaced alongside conventional options. Spaces provides collaborative workspaces where teams organise materials into shared libraries, work with project partners, adapt data as a project evolves and connect their own tools. Kasper, launched in August 2026, is the AI material advisor and the element that makes revalu an AI tool rather than a database: users ask questions in plain language and Kasper draws on the verified product and sustainability data to answer, citing its sources.
Kasper covers four workflows the company describes explicitly. It brings material research into a single conversation instead of a hunt across documents. It compares alternatives side by side, highlights trade-offs between carbon, technical performance, certification and availability, and helps identify the best fit for a project's priorities. It supports early-stage life cycle assessment, matching materials to EPD data, flagging carbon hotspots and testing lower-impact substitutions while the design can still change. The homepage illustrates this with a sample request: performing an early-stage LCA to compare three structural options for a residential building.
A separate component, revalu connect, is an API that pushes live material data into spreadsheets, design software such as Rhino, BIM tools and project management systems, with a built-in quality service that continuously monitors the database and flags expired or incomplete EPDs. Customers can define their own validation rules against it.
revalu also runs a manufacturer-facing offer, where building product makers list materials, publish EPDs and receive a performance report on how their products are found and compared. Access is entirely through a browser; there is no mobile application. Early users named by the company include Henning Larsen, Herzog & de Meuron, LINK Arkitektur, Park Associati, Werner Sobek and CREE.

Pros & Cons
Pros
- Material data is presented as verified and traceable, with continuous quality checking of EPDs
- Large catalogue for a specialist field, with more than 45,000 materials announced
- Life cycle assessment is available early, when design changes still cost little
- An API exists to bring the data into tools teams already use

- Named references from recognised practices such as Henning Larsen, Werner Sobek and CREE
- European vendor under German law, with a detailed and specific privacy policy
Cons
- No pricing is published anywhere, on either the website or the platform
- The API is sold but has no public documentation
- Nothing is stated about whether customer data trains AI models, and no opt-out is offered
- Where platform data is hosted is never disclosed; only the marketing site's hosting is documented
- No security certification such as ISO 27001 or SOC 2 is published
- Browser only, with no mobile application and an English-only interface
- Small inconsistencies remain on the site, including a stale copyright line and conflicting director names
Pricing & Plans
revalu does not publish any pricing. Neither the website nor the platform offers a pricing page, and no figure appears in the platform's own front-end code. Registration is free and creates no purchase obligation, and part of the platform can be viewed without an account for a limited period, but the company never describes a permanent free plan or a free trial. The platform is organised into tiers with limits on workspaces, administrators and collaborators; reaching one of those limits prompts an upgrade handled through the sales team rather than a self-service checkout. Prospective customers should expect to request a quote, and the manufacturer offer is likewise quoted individually.
Data, GDPR & hosting
A consolidated view of how revalu handles your data.
GDPR overview
GDPR implementation is documented in concrete terms. Revalu Impact AG names itself the controller, gives a dedicated contact at dataprotection@revalu.io, and cites specific legal bases: Art. 6(1)(b) and 6(1)(f) for enquiries and orders, Art. 6(1)(a) for the newsletter, and Art. 6(1)(f) for server logs. The full set of data subject rights is listed, including access, rectification, erasure, restriction, portability, objection and withdrawal of consent. Processors are named with their roles under Art. 28: Webflow for website hosting, Personio for HR, HubSpot for CRM and Google Ireland for analytics and CDN, with a DPA and standard contractual clauses where transfers occur. Two gaps are worth noting: the policy carries no effective date or version, and no data protection officer is designated. The company never describes itself as GDPR compliant in so many words.
Who owns the data?
The terms are unusually clear on this point. Customers keep ownership of everything they upload: revalu states that it claims no ownership rights over customer data, that the customer remains the owner of data stored on its servers, and that they may demand its return at any time. In exchange, the customer grants revalu a licence to copy, store, transmit, rearrange, distribute and display that content anonymously, in order to deliver, protect and improve its products and services. The terms add that anonymised data can in no way be traced back to its owner or to the object concerned. Customers remain responsible for their own backups, as revalu accepts no safekeeping obligation.
Reuse rights
Customers may use the service only within their own business activities and through their own staff; the terms forbid using the platform for any competing or commercial purpose without written permission, and forbid scraping it by robot, spider or other automated means. Reusing revalu's own material data outside the product therefore requires the intended route, which is the revalu connect API. In the other direction, data the customer uploads stays theirs and can be withdrawn at any time. The licence revalu takes over that content is limited to anonymised use for operating and improving its services. Nothing in the published documents addresses whether customer data trains AI models, and no opt-out is described.
Data retention & training
Hosting summary
The published hosting information covers revalu's website and corporate systems, not the platform itself. The marketing site runs on Webflow, Inc. of San Francisco, which the privacy policy states uses AWS with data centres within Europe, under a DPA including standard contractual clauses. Personio, used for HR and applicant data, stores data in German data centres. HubSpot, used as CRM, stores data in European data centres and has its European headquarters in Dublin. Google Cloud CDN is supplied by Google Ireland, with transfers to the United States covered by the EU standard contractual clauses, and Google Fonts is self-hosted so no data reaches Google. Crucially, no statement is made about where user data from the platform is stored. The jurisdiction is otherwise clear: German law applies, with Berlin as the place of performance and exclusive venue. Anyone with data residency requirements should ask revalu directly.
Things to keep in mind
Risks and trade-offs to weigh before adopting revalu.
- Kasper's answers support design decisions with real safety and cost consequences: treat them as a starting point and verify against the underlying EPD before specifying
- The terms disclaim any warranty that the service suits a given case, and place the risk of suitability on the user, so professional judgement remains with the practitioner
- Nothing is published about whether customer data trains AI models, and no opt-out exists, so avoid uploading confidential project data until this is clarified with the vendor
- The hosting location of platform data is undisclosed; the European hosting described covers the marketing site and CRM only
- Convenience can erode expertise: relying on a single conversational source for material knowledge risks weakening a team's own ability to read and challenge an EPD
- Environmental data ages, and while revalu flags expired EPDs, a figure carried into a report can outlive its validity
- Certifications named on the site, such as BREEAM, LEED and DGNB, are building certifications the data helps a client pursue; they are not certifications held by revalu
Setup & Integrations
Technical difficulty
Getting started is easy. There is nothing to install: the platform runs in a browser, and access requires only a registration form and a confirmation email. The terms note one technical condition, that cookies set by the platform must be accepted and left unmodified during a session. revalu owes no customisation to a customer's own IT environment unless separately agreed. The one demanding step is integration: connecting material data to spreadsheets, Rhino or BIM tools through revalu connect requires developer involvement and, since no public API documentation exists, direct support from the vendor.

Should you pick revalu?
revalu is a focused, credible tool for a specific moment in a construction project: the early design stage, when material choices are still open and carbon reductions are cheapest to make. Its strength is the combination of a large catalogue of verified, traceable material and EPD data, continuous quality checking of that data, and an AI advisor that makes it usable in conversation rather than through a document hunt. The API gives the data somewhere to go once found, which matters more in this field than in most.
The publisher is easy to verify, which is not always true in this segment. Revalu Impact AG publishes a complete imprint, a register number and a VAT number, operates under German law, and its privacy policy is specific rather than boilerplate. Named reference customers include well-known practices.
The reservations are mostly about disclosure rather than the product. No price is published anywhere, so any evaluation begins with a sales conversation. The API is commercialised without public documentation. Most notably for an AI product, the company says nothing about whether customer data is used to train models, and offers no opt-out; the only relevant clause is a broad licence over anonymised data for improving the service. Where platform data is hosted is also undisclosed, and the European hosting described in the privacy policy covers the marketing site and the CRM, not the product.
For an architecture, engineering or sustainability team already working on embodied carbon, revalu is worth a demo. Teams with strict procurement or security requirements should expect to ask direct questions about hosting, model training and certification before committing.
