The second batch of companies from 500 Startups’ Demo Day

Hybrid incubator and seed fund 500 Startups hosted its second demo day in Mountain View today, where more than 30 companies in the program presented in front of investors and press.

The program is run by Dave McClure, a super-angel who has invested in the likes of Mint.com and Twilio. The firm makes small investments in companies and provides them with office space. It also gives the startups in the program access to a network of mentors.

The firm has invested in 175 companies and has a mentor network with more than 100 members. You can see the first batch of startups that presented at the firm’s Demo Day today here. Here is a breakdown of the second batch of companies that presented today:

ChirpMe: ChirpMe is a match-making site for blind dates. Users list on their profile an activity they are interested in doing — like test-driving a sports car — and find other ChirpMe users that want to do the same thing.

ChirpMe has raised $400,000 from seed investors like Zynga founder Mark Pincus and Zynga angel investor Matt Ocko. McClure is also an investor in the startup. The company is looking to raise an additional $500,000.

From.us: From.us is an online site that crowd-sources the gift-giving process. Users go to the site, add a few gifts to a list and invite friends to add other ideas. The recipient then picks the one they want from that list of gifts and everyone chips in for the present.

The company is looking to raise $250,000 in seed funding.

Welcu: Welcu is an online service for managing high-end events like conferences and shows. The site tracks guest participation and planning in real time. The company works with other event-planning and booking sites like Eventbrite.

Zerply: Zerply is a professional social networking site similar to LinkedIn. You can search for professionals based on location, expertise and other metrics. The site is designed to less corporate than LinkedIn.

WillCall: WillCall is a mobile application that delivers deals on live shows in a specific area. It’s designed for last-minute plans — such as deciding to go see a show five minutes before the band goes on stage. The app provides users with a short list of “high-quality” events for that same day, and tickets are purchased directly in the app with a few button presses.

Volta: Volta is a call management system for businesses. Volta takes the A/B testing approach for websites, where you try out two different versions and see which one gets the best results, and brings it to phone marketing. Companies can create multiple scripts for their phone calls then mark down which conversions resulted in a sale or whatever else they were looking for, and which ones didn’t.

Tinfoil Security: Tinfoil Security is a web security provider that crawls websites for vulnerabilities. The company then reports back to the site about the vulnerabilities and gives the site owners a step-by-step tool for fixing how to fix a site vulnerability.
