Here is my personal list of Top Flex Firms for Q1 2007. The list is based on the consulting firms that I have worked with directly and who have delivered multiple successful Flex applications to clients. In every case you will find that the firms know Flex inside out and are some of the best minds in the business of RIA application development.
Q1 2007 - Top Flex Firms List

If you have a project or need assistance please contact a firm on this list and let them know I sent you.
Disclosure:
1. This list is based on my personal opinion and not of Adobe Systems.
2. I was not paid, influenced, or harmed during the making of this list.
3. All firms are listed alphabetically. (Next list is ordered Z to A)
Over the next six months I am going to be reaching out to consulting firms and I want to get involved in helping your team succeed with Flex. My goal is to grow the Flex marketplace and help you succeed. If your firm would like to get involved, please email me at ted@adobe.com. I look forward to hearing from you.
Congratulations to the teams who made the list, they do world class development and it is time that many of these teams were recognized as leaders in the Flex marketplace.
Regards,
Ted :)

Ted,
I am glad that you stated this was your "personal" list. I had some professional experience with one of the firms you mentioned. I would not be able to recommend them for any Flex work. Can you explain how you derived your list?
what about effectiveUI?
That comments said Effective UI didn't make the list, but then I downloaded the list and see that they did make his list. I was going to say, any list of top Flex firms that didn't include those guys wouldn't be much of a list. The list is pretty much what you would expect though.
I agree with the statement in regards to the "personal" list. I have also had personal experience with one of the firms on your list and I absolutely would not recommend them for any Flex work.
Funny how the negative comments here are anonymous posts...
Also EffectiveUI was listed from the very start, no changes in that PDF since I posted it.
I would like to make a suggestion as to how 'the list' could be better. How about letting clients of those companies nominate them (maybe a via a magical PHP form) and then, based on either 1) the total number of nominations or 2) the most favoring nominations, you derive a list. I guess you could also do this with independent consultants as well. Just a suggestion.
Hmm.. tried to go to

got a unhandled error exposing Path info.
Great list Ted!
How about a followup list of "ones to watch", featuring those that look to be coming up and promising. I'd throw "scale9" on there and some others.
-tim.
This list has some of the really top names.
However for anyone considering consultants, a really good yardstick is to see how many of them have "repeat business" with a major client/firm. Major client/firm being more toward enterprise level as opposed to Joe Consultant's Uncle.
If a good client sends their third or fourth project to the same conusltant, that says a lot.
some Flex developers for other Flex developers, exclusively... :)
Ted,
Thanks for the list! You just saved me a TON of work.
I hope all is well.
