About MadiNi
A two-sided registry for Tanzania's mineral rights. We map every parcel in the national cadastre, and we run the paperwork between the people who hold licences and the people with capital to work them.
The problem we saw
Tanzania issues thousands of prospecting, primary-mining, and processing licences every year. The government keeps an excellent shapefile — but unless you know which office to call, you can't easily tell who holds what, where deposits are, or whether a holder would welcome a conversation.
Meanwhile investors — cooperatives, diaspora funds, regional mining houses — sit on capital with nowhere specific to put it. Deals that should take weeks take years, and most of them die in inbox threads.
What MadiNi does
We render the full cadastre as a live map. On top of it, licence holders post what they're open to discussing: capital partners, joint ventures, outright sales. Investors watch specific parcels, minerals, or regions and are notified the moment a matching listing appears.
When both sides want to talk, we shepherd the conversation: private messages, a document room for geological reports and EIAs, a shared timeline, and a logged trail of who paid what and when.
How we charge
Browsing is free. A fee to post a licence, a fee to submit an interest, a 5% success fee at close. Nothing else. The full schedule sits on a single page.
