Overview
About SaasCity
SaaSCity is an innovative platform designed to revolutionize how startups and SaaS projects are showcased and discovered. Unlike traditional directories that list projects in a monotonous format, SaaSCity transforms each listing into a visually striking 3D building on an interactive isometric map. This unique approach not only makes your project stand out but also provides a dedicated, static project page that is fully indexable by search engines and AI crawlers. This ensures that your startup gains permanent SEO benefits, enhancing its visibility and discoverability over time. SaaSCity is ideal for entrepreneurs, developers, and businesses looking to gain traction in the competitive SaaS landscape. By engaging with other projects and utilizing the built-in marketplace for buying and selling codebases, users can foster collaboration and growth. The platform offers various gamified elements, allowing users to earn points and rewards as they interact with the ecosystem, making it a dynamic space for building a thriving startup community.
About Substy AI
Substy is the first platform to combine a full CRM and an autonomous AI chatbot in a single system built exclusively for OnlyFans and Fanvue agencies - and today it's the most widely adopted solution on the market.
The CRM is a complete agency workspace: add your chatters with custom access levels, let them chat directly from the platform, create and track tracking links (TikTok, Reddit, Telegram), classify fans automatically into Spenders, VIPs, Newbies, and Timewasters, and monitor every chatter's performance in real time - revenue, response rate, average basket.
The AI Chatbot runs 24/7 without human input. It sells PPV, handles objections, re-engages cold fans, and adapts its tone in any language - fully autonomous, not a co-pilot.
The hybrid mode is the game changer: AI handles fans below a spend threshold, human chatters take over only for VIPs. Agencies cut costs by 25% while automating 90% of messages.
Compatible with OnlyFans and Fanvue.
