    I’m looking to build a SaaS platform for jewellery and premium brands that gives every physical product a Digital Product Passport. A brand can register each jewellery piece/product on the platform and attach a unique QR code or NFC tag. When a customer scans it, they see a verified digital passport containing product details, authenticity/certificate information, warranty, and ownership history. The platform should also allow ownership transfers, so when a customer resells the jewellery, the digital ownership record can be transferred to the new buyer. Blockchain will be used as a tamper-evident verification layer for product registration, certificates, timestamps and ownership-transfer records, while sensitive customer/product data remains off-chain.

    I have a suite of proprietary AI tools ready for the market and I need an experienced closer who can turn them into licence revenue with medium-sized businesses—specifically in the retail and manufacturing sectors. The products improve demand forecasting, streamline inventory, and uncover sales insights, so they resonate strongly with operations or IT decision-makers once the value is demonstrated.

Commissions are generous and uncapped, so the more you sell, the more you earn. When you apply, focus on your relevant experience selling software or SaaS licences to similar-sized companies.

    I need an experienced marketer to take charge of promoting HubLaunch (), a cloud-based SASS for developers that eases the mental load of AI churn from developers by moving most AI-assisted work out of their local environment and into the cloud.
