valcu.co (I'm the founder) is automating corporate transactions, with startups currently using the Delaware incorporation and setup tools. We are working on some heavier stuff (e.g., equity financing transactions integrated with a cap table). It's not surprising to me how difficult it is to innovate here as there are so many moving pieces. Scripting up the NVCA forms runs about 250 variables per document and requires conditionals and loops, which most merge tools can't handle. Control provisions, amendment provisions, board rights, protective provisions and many other provisions have to be modeled separately. Share numbers and capitalization reps have to either be entered individually (meaning you have to build a separate model), or the tools have to build in a cap table. It's been build, build, build-we're over 100k lines of code.
