Dead AI dev tools products.
$93M of capital across this category
AI for developers. The category that was supposed to be the easy one - sell to people who would actually pay for software, target a workflow that already had a wallet. Kite predated Copilot by years and could not figure out how to charge. Microsoft retired LUIS and QnA Maker once LLMs made hand-labeled intent classifiers obsolete. GitHub Copilot Voice died because nobody at Microsoft thought it was a real product.
