Boxcar founder Jonathan George delivered a talk Saturday on his experiences as an entrepreneur.

Quoth the great Kevin McCallister (because when isn’t a Home Alone quote at least marginally appropriate?): This is it. Don’t get scared now.

Just a few hours stand between Startup Weekend Kansas City participants and their final presentations, which get underway at 6:30 p.m. here at the bizperc office space.

Rest assured, “getting scared” won’t be a problem here. Teams seem far more excited than apprehensive, thanks to a busy second day of Startup Weekend on Saturday. Folks hit the streets and fired off tweets — for market research and buzz-building, respectively — as teams hunkered down and the ideas pitched Friday started to take shape.

Mentors from the local business community stopped in to gauge progress and dispense advice, and Boxcar founder Jonathan George delivered a talk on his experiences as an entrepreneur. George offered plenty of interesting insights when we profiled him in advance of Startup Weekend, and he continued that trend Saturday. A few highlights from his talk:

• George said he built Boxcar basically over the course of a weekend in 2009, but he did so without the structure of something like Startup Weekend. “I think its super cool that this actually exists now,” he said. “What you’re doing now, you can totally turn this into a startup.”
• In a move that seemed especially apropos given that it was foursquare Day, George quoted foursquare founder Dennis Crowley: “Building a product is easy. Building a company is hard.” George said he’s built nearly 200 products over the last 10 years. Two of those have become companies.
• George has experienced a difficulty he said Startup Weekend teams interested in carrying their ideas forward can expect to face, too: turning a product into a business that delivers value to others. “The really, really long road ahead of you,” he said,” is actually turning that (product) into something that’s valuable to other people too.”
• Watching his father, also an entrepreneur, George said he came to appreciate something unexpected about startups. “No one really was about the money,” George said. “It was about being able to help other people.” To this day, George tries to make that a central tenet of what he does.

We’ll have more from George next week. In the meantime, here are some photos I took from Day 2 of startup weekend.
