Last week at TechCrunch50, a slew of great companies were showing off their services in the DemoPit. And although not all of them were able to fully show off how their sites could work on-site, one company, MyJambi, was lucky enough to do just that.

MyJambi is a social marketplace where users can buy and sell services online without the use of anonymous service postings. Anything from childcare to cooking lessons is available for purchase on the site now, which is currently matching about 9,000 buyers and providers since its launch last week.

Once you sign up for an account on MyJambi, you have the option of either providing services for a set fee or looking for people that provide services you’re looking for. Once you find one, you can hook up with that person who will then perform the service.

Privacy and safety issues aside — you are inviting people you don’t know into your home, after all — MyJambi has already been put to good use. According to the company’s founder, his “coffee retrieval” skills were shown off at TechCrunch50 when the team at SuggestionBox bought his services at the conference.

For a fee of $5 per coffee run, the SuggestionBox team sent MyJambi’s founder to the local Starbucks to pick up some coffee. And just as the company promises, it worked as advertised — the founder performed the service and the SuggestionBox team paid up once it was satisfied.

It looks like TechCrunch50 really is more than a launching pad for your startup.

SuggestionBox is trying to solve this problem. Their site, which launches today in beta, offers a replacement for the standard feedback form many of us have become accustomed to ignoring. In lieu of this, SuggestionBox has designed a full-featured suggestion management system that should make the process faster and more rewarding for companies and their patrons alike.

After creating an account, users can submit suggestions to each participating company’s SuggestionBox. Members can keep track of the progress of each of their suggestions, as they each have status messages that are controlled by the relevant company indicating if a suggestion is under review, being implemented, or has been ruled out. And each suggestion submitted can also be rated by other members to give companies an idea of which ideas are urgent, and which are simply nitpicks.

The skeptic in me says that while the idea is nice on paper, many companies are going to balk at the idea of investing time and manpower into individually addressing suggestions left by their customers. The software does allow for categorized suggestions that can be dealt with in mass, but everything needs to be manually sorted initially- there’s nothing automatic. And even if a company takes the time to set up an account, I wouldn’t be surprised if the vast majority of suggestions wind up “under review” for eternity.

But despite my concerns, I think SuggestionBox has a chance. If just one large company does implement the system, and the response is as positive as SuggestionBox is hoping, then this kind of software could quickly become a staple in retail and service industries. Many consumers apreciate even trivial gestures of good faith from businesses (some large retailers require managers to call customers that have reported bad service for this very reason).

SuggestionBox is based in San Diego, and is privately funded. It faces competiton from UserVoice, Get Satisfaction, and a number of other customer service focused startups.
