Trending: Elizabeth Warren takes aim at Amazon’s taxes again during speech at Seattle rally
Codementor founder Weiting Liu at TechStars Seattle Demo Day

We just watched 11 great pitches from the TechStars Seattle Demo Day, taking place at the Showbox Sodo in Seattle.

The pitches were polished. The entrepreneurs were sharp. And a few might just change the world. But at the end of the day, my colleague Taylor Soper and I had a few companies we liked the most — both from a presentation standpoint and overall demonstration of revenue model.

Perfect co-founder Hudson Duan pitches at Techstars Demo Day.

John’s top pitch: The pitch for Perfect’s was nearly … perfect. Personal — great connections to the entrepreneur’s grandmother — and succinct — it had the most memorable one-sentence pitch of the day from co-founder Hudson Duan.

“Perfect is the ongoing movie of your life.”

Now, I am not sure if Perfect will make a great business. In fact, if I were placing my own dollars on the table, I’d be reluctant to bet on a company that’s built around Google Glass. But I did like the storytelling capabilities of the entrepreneur, and his very simple and thoughtful presentation.

Don’t worry folks, I am not about to start “lifeblogging.” That said, the future will be documented and recorded. Perfect could help people get comfortable with that idea.

Taylor’s top pitch: I absolutely loved the energy from Wire CEO Piragash Velummylum. His presentation was at times slightly overwhelming because it felt like he was yelling at you, but there was no doubt the man had the crowd’s full attention.

Also enjoyed the app’s demo, which featured a rapid-fire conversation between two teenage girls — a very real-world, applicable use case that showed the value of Wire, a messaging app.

Another nice touch: SnapChat was the first thought that came into my head when Velummylum started speaking, so the side-by-side comparison with SnapChat was clutch.

“Did you catch that?” Velummylum asked the crowd as a SnapChat photo appeared and vanished. “Of course not — it’s SnapChat, it just went away. Wire allows you to see the message, it allows you to see the photo — you can read the text, damn it!”

But like John, I’m not so sure about Wire’s business model. Velummylum talked about the massive market opportunity in the mobile messaging space, but Wire isn’t exactly fixing any big problem. Will it become the next SnapChat or WhatsApp? I doubt it.

John’s top business model: Codementor seems like it is solving a big pain point, helping developers get expert advice in real time. It’s also a smart way for expert coders to make extra money and earn credibility through Codementor’s review platform.

In fact, there was a theme today in the presentations — online education technologies that help software developers do their jobs better. (Also, this was apparent in Shippable, and to some extent with Everpath)

Building a marketplace for instant coding help is a solid idea and CEO  Weiting Liu —a Y Combinator grad who previously sold his first startup SocialPicks in 2009 — did a great job showing the crowd why. Not only did he have a polished presentation, but Liu also outlined a convincing revenue model and showed how companies can save time and money by speeding up the troubleshooting process for developers.

If I had to pick my favorite business model from today’s lineup, it’s Codementor.

Taylor’s top business model: The last presentation was certainly not least, as CEO Brewster Stanislaw clearly outlined the benefits of Inside Social. Companies might be using social media marketing, but how can they tell which verticals are actually helping the bottom line?

Stanislaw had a great pitch, showing how 75 percent of companies have no idea how to measure ROI on social media outreach. It’s a very real problem, and Inside Social seems to have a real solution.

I’ll give an honorable mention to the folks behind Shippable. I love companies that are solving an actual problem that people have, and CEO Avi Cavale seems to have a great plan in place to fix a common developer’s dilemma: speeding up software development. Plus, Founders Co-Op General Partner Chris DeVore announced that his firm is investing in Shippable — another obvious vote of confidence for the startup.
