Frequently asked questions about Prewave and RUBINLAKE
For finding new suppliers, yes: RUBINLAKE finds companies in the DACH region, shows register data, figures and signals, and provides the right contacts. For due diligence, sub-suppliers and audits, Prewave is the right choice, and we offer no replacement for it.
No. RUBINLAKE is not a due diligence tool: there is no LkSG risk analysis, no questionnaires, no management of measures and no report. Anyone who has to meet those duties needs a platform like Prewave. RUBINLAKE helps before that, with finding and checking suppliers, and alongside it with signals on individual companies.
Prewave publishes no prices. The scope depends on the supplier base and the requirements and is agreed in a conversation. RUBINLAKE costs €59 (Essential), €199 (Premium) or €449 (Enterprise) a month, less when paid yearly, and can be cancelled any month.
