If one thing is clear at this year’s TechCrunch50 it is that Web 2.0 is permeating the business world.

Entrepreneurs, having watched the rapid adoption of consumer Web sites such as Facebook, YouTube and Twitter, are hatching companies to take and adapt these technologies for the corporation.

“I think there is a big movement toward the enterprise,” notes Keith McCarty, marketing manager for Yammer.

One company hoping to capitalize on the trend is iCharts, a 1-year-old Sunnyvale company preparing for a Wednesday launch of its online charting application. Target market: business users.

Just upload data from a Microsoft Excel, and the site will create a chart for free that someone can then link to a Web site or blog. For a fee, the chart can be downloaded for use elsewhere and off line.

ICharts likes to call itself the YouTube of charts and estimates 900 billion charts are printed every year, only about 40 million are posted online.

“With the start of what is called Web 2.0, I think many companies made the mistake of 10 years ago,” said Tyron Montgomery (pictured), CTO. “They got into mass markets where they can’t make any money.”

Companies today are brainstorming ideas in the business market to make money, he said.

Hoping to enter the enterprise market with a communications tool is Yammer, which bills itself as the Twitter for business. Companies can take advantage of its online service to install private Twitter-like networks for employees, where people post comments about work and share the comments with others. The service launched Monday.

Personal productivity software developer Jibidee is targeting small online spreadsheets and tiny text documents designed to keep track of what’s going on in a person’s life.

People can have four or five documents open at one time because they are not as big as a Google Doc, said Allen Clary, CEO and founder of the Tampa startup. The site launched on Tuesday.

At MyJambi, Director of Product Operations Nellwyn Thomas wants providers of business and consumer services to list their products so that potential buyers can come and find what they need.

Since the site launched in July, 8,500 buyers and providers have registered and 70 transactions have taken place. The top transaction categories are babysitters, tutors and pet sitters.

After a transaction, buyers can reviews their experience and MyJambi gets a small cut of the deal.

“I think there is a big paradigm shift underway” toward buying services and products based on online reviews, said Scott Bromley, an associate for the venture capital firm Greycroft Partners. But “I think it takes some time for people to get comfortable with the idea.”
