conclusia builds and maintains company longlists. Connect it to Claude and you work on those lists in the conversation instead of switching to the web app. Ask for a list and conclusia's own research system takes over: it turns your brief into explicit criteria, pulls candidates from a base of millions of active companies, and validates every candidate against live web evidence. Coverage is strongest in Europe and on the small and mid-sized companies a normal web search never surfaces. Read your lists and page through the companies on them with their research answers. Look up what conclusia knows about a single company by its website or name. Create a new list from a description of what you are looking for. Refine one that already exists, or narrow it by country, region and company size. Price a research column before it runs, then start it - one question answered for every company on the list, gathered from the open web. Export the list as an Excel file. And tell the conclusia team when the product could not do what you asked. You sign in with your own conclusia account and Claude sees exactly the lists you see in the web app, and nothing else. Nothing that deletes, archives or shares a list is exposed here - those stay in the web app, where you can see what you are doing. There is a free plan, so a new account can build a list, read the first twenty companies on it and export them, without a contract.
