There are a lot of firms that can get you up and running in a few weeks. They sell generic hedge fund formation packages, which give you all the tech/PB access. It's very rudimentary, but a lot of people do seem to opt for them, especially those that don't know what they're doing.
You have to code:
- Feed handlers
- Back office
- Research platform
- Strategy execution
- GUI
You need to have:
- PB agreements
- Network access (telco the world over suck as doing this in a reasonable time)
- Exchange memberships / ISDAs (depends what you're up to)
I guess you could have spun out from a larger group with some of this stuff, but then you'd probably not crash and burn that fast.
I do agree with the sentiment that fast talkers get more money than they can handle.
