I need someone to build a competitive research in a specific tech area

I would like a (1) list of every single company that does text analytics via NLP (natural language processing) AND/OR ML (machine learning), (2) the researcher should propose ways for these to be grouped along with reasoning, (3) the researcher should find information in specific areas that would be pre-defined, (4) the researcher would have to also provide a list of (a) businesses that were acquired, (b) funded, (c) sold their IP or (d) went bankrupt in the area. Exemplary companies to be included in the research are Alchemy API (acquired by IBM), Clarabridge, Indico, BasisTech, Meaningcloud, Lexalytics, Bitext, Stanford NLP (open source technology), Attencity (sold IP), idibon (went bankrupt). Your job would be to find these companies, doesn't matter if they are providing an end-to-end solution like Clarabridge, only an API and Excel plug-in like Lexalytics or are an open source solution (Stanford NLP). You'd need to figure out who these are, propose ways to group them and then find information on specific things such as potential revenue, employee count, key industries they operate in (list of these specific things will be provided). It is VITAL that you provide sources for every piece of information. If this founding research is done well, this could lead to an expansion of the task into other areas with this is a foundation.
