What is WhatAreYouBuilding.AI?
WhatAreYouBuilding.AI is a free standing directory of what independent builders are shipping. AI, SaaS and dev tools, filterable by country, category and funding stage. A listing stays free. It is reviewed before it appears. The outbound link is dofollow, and builders do not have to put a badge on their site to get it. The catalogue is also readable by agents. There is a public MCP at https://whatareyoubuilding.ai/api/mcp and an llms.txt at https://whatareyoubuilding.ai/llms.txt. Reads need no key. It is a product catalogue, not a registry of MCP servers. Founder is Neta Dror. One product per builder.

2722 dispatches from hundreds of founders, pulled from the week's best podcasts.
it is almost impossible to build a real business without that so you really need to understand your customers because what you I see I have some friends who who are building a product and they want to launch it in the building feature after feature after feature before launch they don't even know who's going to use the product
Launch barely-working software early, then let users move the product
Klemke pushes back on founders stockpiling features pre-launch. The play: ship as early as possible with barely-enough functionality, then talk to as many users as possible and let those conversations move the product. Real customer understanding beats guessing in private — and the only way to get it is to have users.
Base users who have been using the app for 30 days and they haven't converted — the only way we have a prayer that they convert is if they leave and then come back and we hit them as a reactivated user.
If a free user hasn't converted by day 30, only churn-and-return saves them
Lose It!'s data shatters the freemium-lottery promise that base users 'will convert eventually.' After 30 days without conversion, the only realistic path to paid is churning out and being reactivated under a heavy discount offer. The implication: stop hoping the base will convert in place — engineer churn-and-return loops instead.
There's a play for whatever you're stuck on.
