One supplier, two perspectives
Risk view and company view
Isartal Robotik AG is a fictional example. The company view asks who the company is and whom to contact there. The risk view asks what is happening at a listed supplier.

If you want to find, check and contact new suppliers in the DACH region, RUBINLAKE fits. If you have to meet legal due diligence duties and monitor your supply chain down to sub-suppliers, there is no way around a platform like Prewave.
Transparency
We love transparency. That is why this page also says where others are better.
Competitive intelligence is what RUBINLAKE does every day for sales, procurement and recruiting teams. We hold ourselves to the same standard: public sources, a date and an honest verdict for every task.
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.
You filter 7M+ companies in the DACH region by industry, size, region and figures, or search in plain sentences. From an existing supplier, lookalikes find similar companies as a second source; you check the register and the annual accounts and unlock the right contact.
82 event types from mostly German-language sources, in the supplier perspective, with priority, sources and a daily overview. They include moves, growth, management changes or news about economic difficulty. It is not a replacement for risk monitoring under legal requirements.
No. RUBINLAKE sees the individual company, not its supply chain. Prewave maps indirect suppliers, cluster risk and dependencies.
Yes, and the split is clear: RUBINLAKE up to the contract, meaning finding, checking and contacting suppliers, and Prewave after it, meaning monitoring and providing evidence.
