Personally for quick and easy reviews i find ProofHub the best. Give it a try.
Here it is: http://www.proofhub.com/mini

First let me say congrats to both @scott and @mat, you have really amazing products guys (and great ways of managing communication, community…)

So I’m the cofounder of a small but nice French startup and we are doing UpShot (http://upshotapp.com).
It’s kind of half a competitor and half the perfect partner to those feedback tools.

We focus on simplicity and efficiency which means that every non techie customer can understand how it works within 15 seconds.

Why is it competition? Well because we basically work on the same concept (helping designers get more time to create)

Why is it that complementary ? Because ConceptShare or ProofHQ fit perfectly for exchanges between designers or designers and DAs but might be too much for end customers or people processing lots and lots of picture reviews.

Anyway, cool to e-see you guys !

Thanks for the review Andrew and for the comments.

@Scott. Completely agree that moving to tools like this is an evolution for clients. Some jump straight into it and others needs handholding. Once they do jump thought, the productivity gains are great.

Just to clarify, ProofHQ does have workspaces within which proofs can be organised by project/client – in fact any way that you want. Proofs also have versions, so you can quickly and easily keep track of all revisions of a design, including all comments.

Although to me everything seems very straightforward, it may not be quite as easy for some of our non web savvy clients who aren’t used to web interfaces. I haven’t really had time to test it out properly yet but I’m impressed with what I’ve seen so far and think it could be a really useful tool.

Where I see the main point of differentiation is ConceptShare bases the interaction on a workspace. The workspace is the central communications point for an entire project not just for proof.

ConceptShare allows users to manage the project and all the visual assets for a project. So if you could imagine that a project, it is never just one piece, there are websites, minisites, iphone apps, banner ads, POP, vehicle wraps, billboards, videos. With all of the associated visual data that needs to be discussed it becomes a communication nightmare. ConceptShare allows the user to jump in and make the comments and have discussion with others over the visuals. This allows the designers to get the feedback they need to move forward on the designs with out having to chase feedback as the system manages all the notifications. So our approach is more project centric from cocktail napkin sketches to final product.

I think that these types of tools fix a fundemental problem with the way that we worked this end of the business. I think the less time chasing, interpreting faxed back comments, digesting feedback from multiple project stakeholders is a win for any company.

The way most companies handle this sort of interaction is based on systems and processes that evolved for the days before computers. The “systems and processes” then transformed to meld with the advances of fax machines and then email. Each time the process changed a little bit to accomodate the new technology but was still rooted in the old logic.

These new collaboration products allow people to collaborate and communicate over visuals deliver a huge advantage to companies that choose them. It is certainly something that will make lives easier for designers, Art and Creative Directors, Marketing Managers, UX designers, and the list goes on. Oh yeah your clients will love them too.

Cheers
