Renaldo
German platform for residential construction and renovation projects. Costs and schedules are both derived from the same building model, using real regional trade prices, with an AI assistant covering acquisition, tendering, site work and portfolio operation.
What is Renaldo?
Renaldo is a German platform that treats a residential building project as a single data set rather than a chain of disconnected tools. Its central claim is that the two questions that decide a build, what it costs and when it will be finished, are answered from the same building data, so the two answers always agree.
On the cost side, a works item drawn from a library spanning more than twenty trades is multiplied by a quantity taken automatically from the building and room data, then by a real regional contractor unit price. The result is costing without manual quantity take-off, with every line tied back to the building itself. A three-step confidence indicator shows whether the current figure is a rough estimate, a dependable number, or ready to go out to tender. On the schedule side, task durations come from the same configuration, dependencies cascade automatically with buffers when something moves, and the trades report progress back through a portal that needs no account and works offline on site.
The platform spans six phases: acquisition, planning and costing, tendering and award, construction and handover, operation, and sale. Early on it pulls official German data such as guideline land values, cadastral maps, permitted density and official 3D building models, then computes gross development value, margin and residual land value. Later phases add AI bid comparison that flags missing items, AI invoice checking, a weekly site report, defect management, tenant and maintenance handling, and an ESG rating that feeds straight into a costed renovation.
Running through all of it is SAM, an assistant taking voice or chat input, aware of the project at hand and versed in German building regulation, funding schemes and building physics, which adapts its register to whoever is asking.
Four audiences share one project file: housing professionals, private clients and their advisers, general contractors, and the trades, who use it free of charge. Building models import from Doorbit, Hottgenroth, EVEBI and IFC. The product runs in the browser and as iOS and Android apps, and the publisher also sells a German-language training track for renovation coaches.
What it does
- Test whether a plot is financially viable and calculate the highest land price it can carry
- Cost a project without measuring quantities, because they come from the building model
- Produce a tender-ready schedule of works without writing it
- Compare contractor bids with AI against your own schedule of works, including the items nobody quoted
- Run a construction programme that rewrites itself when a task slips
- Check eligibility for German BAFA, KfW and BEG funding and track the applications
- Review incoming invoices with AI and export a white-label or financing PDF for the bank
When to use Renaldo / When not to
A quick filter to help you decide if Renaldo is the right fit.
When to use Renaldo
- Property developers running fix-and-flip, unit-splitting or new-build apartment schemes in Germany, who need a residual land value before they commit to a purchase
- Housing companies and cooperatives analysing an existing stock for serial renovation, with unlimited users under a single per-unit platform fee
- Architects, structural engineers and energy consultants who cost projects and write tender documents, and who want quantities taken from the building rather than measured by hand
- General contractors coordinating subcontractors, who need a schedule that reprices itself when a trade slips
- Private homeowners building or renovating their own house who want to see cost, funding eligibility and completion date in one place
When not to use Renaldo
- Anyone working outside Germany: the land values, building code, funding programmes and trade prices that make the tool useful are all German, and the publisher declares Germany as its service area
- Teams working on commercial, industrial or civil engineering projects, since the whole data model is built around residential buildings
- Organisations that need to push data into their own systems, because the product exposes no public API of any kind
- Buyers who require a signed data processing agreement or a recognised security certification before purchasing, as neither is offered on the site
- Anyone who needs to read the full contractual and application privacy terms before signing up, since no terms page is currently reachable and the application policy sits behind the login
How to use Renaldo
A typical end-to-end flow, from setup to results.
- Try a quick cost estimate straight from the site, which the publisher says needs no sign-up at all
- Open a free account on the web application, where the entry tier stays free permanently on every product
- Start a project from a street address, so the platform can pull official land values, cadastral data and permitted density
- Or import an existing building model from Doorbit, Hottgenroth, EVEBI or IFC instead of typing anything in
- Configure the works across five levels, from trade down to a tender-ready line item, taking the suggested planning services when prompted
- Read the cost and the programme that the configuration produces, and watch the confidence indicator move as the data firms up
- Set a target budget to see costed levers ranked by energy gain, value uplift or shortest build time
- Send the generated schedule of works out to tender and compare returning bids with the AI price mirror
- Invite the trades, who respond through a link without creating an account, and let the programme update itself from their feedback
- Add colleagues, clients or financing partners with their own roles and rights, and export white-label or financing PDFs as needed
Pros & Cons
Pros
- Cost and programme come from one model, so they stay consistent in a way that separate tools structurally cannot
- Real regional contractor prices instead of generic cost-per-square-metre ratios
- A permanent free tier on every product, and full free access for the trades doing the work
- The contractor portal needs no account and works offline on site, which removes the usual adoption barrier
- Official German land, cadastral and 3D building data are built in, with no extra subscription to arrange
- German funding programmes are checked automatically rather than researched by hand
- Web, iOS and Android all show the same project state, with monthly cancellation and no lock-in claimed
Cons
- The product is inseparable from the German market: outside Germany the data, funding checks and prices largely do not apply
- No terms and conditions page is reachable at the time of review, so a subscription is taken out without contractual terms available online
- The privacy policy governing the application, and therefore project data, can only be read after signing in
- No data processing agreement is offered and no security certification is claimed, which will block some professional buyers
- There is no public API, so the platform cannot be wired into an existing toolchain
- Seven products with mixed billing units, per person, per dwelling, per project value and one-off, make genuine comparison hard work
- The professional Expert tier triples after six months, moving from a launch rate to the standard monthly price
Pricing & Plans
A permanent free tier, named Start, is available on every product and is not a time-limited trial, and trade firms are given access at no charge at all. The lowest paid entry point is EUR 19 per person per month, excluding VAT, for the Partner tier aimed at mortgage brokers and estate agents; that tier is advertised at EUR 0 because the following month is waived once a client referral is made. For building professionals the entry point is EUR 49 per person per month for the first six months, after which it becomes EUR 149 per month. Several tiers are priced in units that this directory cannot express as a single figure: the asset management tier is EUR 9 per dwelling per month with no base fee, the housing company platform fee slides from EUR 6 down to EUR 1 per dwelling per year with a EUR 1,490 annual minimum, and the homeowner tier is a one-off EUR 199 payment for lifetime access, inclusive of VAT. All other prices are quoted net of 19 per cent German VAT. Free trials run 30 days on the seat-based tiers, without a card, and 60 days on the value-based ones.

Data, GDPR & hosting
A consolidated view of how Renaldo handles your data.
GDPR overview
Implementation is documented and specific, though uneven. The privacy notice carries an April 2026 revision date, names the controller with full company details, and lists the data subject rights under Articles 15 to 21 plus the right to complain to a supervisory authority, all exercisable at the published support address. German national rules are cited alongside the Regulation. Third country transfers are said to rest on adequacy decisions, standard contractual clauses or consent. Consent is managed through a Cookiebot banner. Named processors are unusually explicit. No data protection officer is designated and no Article 27 representative appears, which is consistent with a controller established in Germany. Two gaps matter: no data processing agreement is offered to customers, and no security certification is claimed anywhere. One statement also conflicts with another page, as noted below.
Who owns the data?
Renaldo GmbH is named as the data controller for the renaldo.de marketing site, at its Hamburg address. The published policy covers that site only: a separate policy governs the application at app.renaldo.de and is reachable solely from inside the product after signing in, so the ownership and handling of actual project data cannot be verified before registering. On the public site, conversations with the SAM assistant are described as stored without any link to a person, with no IP address and no account, under a random session identifier, and visitors are explicitly asked not to type personal data into the chat. Chat content is passed to Anthropic acting as a processor on the publisher's behalf.
Reuse rights
The collected pages set out why data is processed rather than granting or withholding any reuse right to the end user, and no clause was found that lets a customer reuse content from the platform without asking. For the public site the stated purposes are running the site, answering enquiries, audience measurement and marketing, the newsletter, and security, resting on consent, contract, legal obligation and legitimate interest. Chat content goes to Anthropic as a processor, with transfers to the United States covered by standard contractual clauses or the EU-US Data Privacy Framework, and is kept to understand what visitors ask and improve the offering. Analytics and advertising tags load only after consent through the Cookiebot banner. The publisher lists the services used inside the application, including a voice assistant powered by OpenAI, text chat by Anthropic, AI review of quotes and invoices, payments through Stripe and address lookup through Mapbox, but the rules attached to that processing live in the separate application policy.
Data retention & training
Hosting summary
The publisher states hosting in Germany, but that statement appears in a values block on its About page rather than in the privacy policy. The section of the policy that actually deals with hosting names neither a provider nor a country, so the claim is not corroborated where it would carry weight. Server log information is kept for a maximum of thirty days and then deleted or anonymised. Two country statements found elsewhere belong to third parties rather than to the publisher: the analytics provider etracker is described as processing exclusively in Germany, and the newsletter service Mailjet as having European hosting in France. Transfers to the United States are contemplated for the analytics, advertising and AI chat services, resting on standard contractual clauses or the EU-US Data Privacy Framework. The site is served through a content delivery network whose resolved address geolocates to the United States; that is an edge node and says nothing about where data is stored. Hosting arrangements for the application itself are not documented publicly.

Things to keep in mind
Risks and trade-offs to weigh before adopting Renaldo.
- No terms and conditions page is reachable at the time of review, so you would be subscribing without the contract available online; ask for it in writing before paying
- The privacy policy covering the application, and therefore your project and client data, is only readable after you sign in, which reverses the normal order of informed consent
- The site contradicts itself on tracking: one page promises no trackers while the privacy policy declares analytics, advertising and social pixels loaded after consent
- Hosting in Germany is asserted in a values statement, not in the hosting section of the privacy policy, which names neither provider nor country; treat it as a claim to verify
- The AI assistant explicitly warns that its answers are generated automatically, may contain errors, and are not legal, tax or binding funding advice; on regulated German funding that distinction carries real money
- Automatic quantities and generated schedules of works invite over-trust: a confidence indicator is provided precisely because early figures are not tender-grade, and the responsibility for checking remains yours
- German funding programmes and building standards referenced throughout are the subject the software works on, not credentials held by the publisher, which claims no security certification of its own
Setup & Integrations
Technical difficulty
Low. The publisher claims no implementation project is needed and describes the product as mobile-first, and a quick cost estimate is said to be possible without even registering. Existing building models import in one click from Doorbit, Hottgenroth, EVEBI and IFC, so a project can start without manual entry. Contractors install nothing and create no account: their portal opens from a link and works offline. The real effort is not technical but methodical, in configuring works across five levels down to tender-ready line items. Custom onboarding is included only in the higher team tier.

Should you pick Renaldo?
Renaldo is unusually coherent for its category. Deriving cost and programme from a single building model is not a marketing line but a design decision, and it produces something separate estimating and scheduling tools structurally cannot: when a date moves you see what it costs, and when a decision is taken you see what it does to the programme. Pairing that with real regional contractor prices, rather than generic rates, is the part professionals are most likely to value.
That strength is also the boundary. The platform is built on German building regulation, German funding schemes, German land value data and German trade prices, and the publisher declares Germany as its service area. Read as a German product it is strong; read as a general construction tool it is not portable.
The commercial side is thoughtfully segmented, with a genuinely permanent free tier on every product and free access for the trades who actually do the work, which removes the adoption problem most site tools run into. It is also hard to compare: seven products priced per person, per dwelling, per project value and one-off, with a professional tier that triples once the launch period ends.
Legal transparency is the weakest point and deserves attention before committing. The German legal notice is exemplary, but no terms and conditions page is currently reachable, and the privacy policy that governs actual project data can only be read after signing in. There is no data processing agreement and no security certification. One page also promises no trackers while the privacy policy declares several.
The free tier makes evaluation risk-free, and that is the sensible way in: build a real project, then ask for the contractual documents in writing before you pay.
