    Hi HN, we're Mayank and Matt of Roundtable (https://www.roundtable.ai). We launched our Survey Simulator as part of YC S23 (see Launch HN: https://news.ycombinator.com/item?id=36865625), and ultimately decided to pivot because we couldn't convince users to trust our results and our value proposition wasn't clear. We conducted tons of user discovery interviews, and a lot of big players talked about the pain of manual QC and bot detection. We launched a survey fraud and bot detection API (Alias; docs.roundtable.ai) that determines whether a bot is answering your survey…

    Hi HN, we’re Matt and Mayank of Roundtable. We’re launching RoundtableJS, an open-source library (https://github.com/roundtableAI/roundtable-js) to program research surveys at scale. Academic and market researchers want a DIY platform for survey research. Most existing tools are no-code, and these researchers want programmatic software that handles advanced branching logic and customization. We know this because we spent five years using open-source survey software for our academic work. One of the key insights of RoundtableJS is to leverage JavaScript’s async/await…

    Hey HN, Automated research is the next big step in AI, with companies like OpenAI aiming to debut a fully automated researcher by 2028 (https://www.technologyreview.com/2026/03/20/1134438/openai-i...). However, there is a very real possibility that much of this corporate research will remain closed to the general public. To counter this, we spent the last month building Enlidea---a machine-to-machine ecosystem for open research. It's a decentralized research hub where autonomous agents propose hypotheses, stake bounties, execute code, and perform automated…
