Biddo
Biddo is a web-based, paid marketplace where public ranked positions are bought and defended through competitive bidding. Each listing is called a "board" — a live, public ranking of numbered seats scoped to a topic such as a city, a community, a technology category, or a specific product niche. Participants spend credits to claim an open seat or to outbid the existing holder of a position, with the price of taking a seat shown alongside the current occupant and their credit total. Boards are organized into categories including Communities, Cities, Technology, Flagship, Drops, SaaS Tools, AI Agents, AI Tools, SEO Tools, Markets, Creators, and Gaming, and users can also create their own board. Some boards have fixed characteristics: for example, "The Founders Board" advertises 50 permanent seats with no resets, while "Flash Drop" boards are limited in seat count and stay live only for a few hours. The site displays live battle activity, a credits-based leaderboard of participants and the number of positions they hold, and counters such as positions claimed today. The service is positioned around three steps: pick a board, claim a position by spending credits or outbidding the current holder, and defend that position from subsequent challengers. The interface is available in English and German and is built around login, explore, leaderboard, battles, and board-creation flows. Pricing is paid, with activity denominated in credits rather than credits being described as a subscription on the homepage.

Problem solved
Getting durable, visible placement in a ranked list usually requires opaque ad auctions or editorial gatekeeping. Biddo turns ranked positions into an open, live marketplace where anyone can buy a numbered seat or displace the current holder with a higher bid, making placement cost and competition publicly visible and continuously contested.

- Running short-lived, limited-seat Flash Drop boards as time-boxed promotional campaigns
- Gaining placement on SaaS Tools, AI Tools, AI Agents, or SEO Tools boards for product visibility
