“Entrepreneurship can be learned.” This was the emphatic message told to the audience at last week’s TechStars Demo Day in Boston, a two and a half hour run of energetic pitches made by a select group of thirteen high potential startups to friends, family, and about 200 investors.

TechStars is a startup accelerator with programs in cities with high tech presence across the country. After being accepted to TechStars (no easy feat, given their 99% rejection rate of the thousands of applicants they get each year), companies have three months of intense mentoring and are given hundreds of thousands of dollars in initial seed investment and perks including everything from office space to legal fees. 

At every city’s Demo Day, the CEO of each startup will do his or her best to convince the investors to further fund them. And while traditional web startups make up a substantial portion of the presenters, they’re by no means the only ones. Some of the highlights from the day included:

-Fashion Project: Anna Palmer and Christine Rizk, two former Harvard lawyers, started a company that sells used donated fashionable clothing at fair market value and directs a portion of the profits to charities, rather than letting them go to thrift stores and be sold for pennies on the dollar. According to Palmer, “Charities leave $4 billion every year” by underselling valuable products. In Fashion Project’s pilot program, nonprofits “raised five times more from donated clothing” than they had on their own. 

-Ovuline: Led by Alex Baron and Paris Wallace, Ovuline is a system that includes “a basal thermometer, ovulation test strips, male and female fertility vitamins” and much more, all designed to help women conceive. Coupled with their web and mobile apps, to date they’ve helped 1100 couples conceive three times faster than the US national average. They even guarantee that “You will get pregnant in the first 6 months of using Ovuline.”

-NBD Nanotechnologies: Miguel Galvez, Andy McTeague, and Deckard Sorensen are founders of a company that designs a device based on the Namid Desert Beetle, an insect that uses “superhydrophobic and superhydrophilic” properties to collect moisture from the air into drinkable water. Their goal is to deploy such devices in parts of the world where water is scarce, but ultimately they urge to “Imagine a water bottle that can fill itself.”

-Zeppelin : Founded by Davorin Gabrovec and Vlada Petrovic of Slovenia, Zeppelin pulls enterprise cloud applications all into one platform, allowing for companies to do three things: “see actionable alerts, achieve business insights,  and have a single place for conversations.”

Other companies promoted ways to improve health care, personal finance, and even to jump higher.

With an average post-TechStars funding of $1.6 million and 77% of all companies still active, it’s probably not too soon to sign up for 2013.
