Full applicationCanadaKaz designed Canada’s Startup Visa. Paul Graham once blogged that this policy was “the single biggest thing the government could do to increase the number of startups in the country.” Many people agreed and for nearly a decade people had tried to make it happen.

Lollipuff(W13)
Full applicationTravis (beambot): During my PhD I designed, constructed, and/or programmed three human-scale mobile robots (EL-E, Cody, and the PR-2) and was an early contributor to the open-source Robot Operating System (ROS). I pulled off an autonomous, sensor-driven robot demo on live TV (CNN) -- a rare (and gutsy!) move in the robotics world. Fei (bebefuzz): According to power industry veterans, I was the youngest ever regional sales director in the power automation industry -- doubly impressive as a woman (rare!) in a male-dominated industry. David (dmohs): I am passionate about writing software that makes its users' lives better. At Sandia National Laboratories, I took over an ailing project to help counterintelligence personnel protect classified information. Working closely with these users, I built a new version of the existing application from scratch which was much more responsive and easier to use than anything they had seen previously. At the end of the project, the users were happier, more productive, and had become advocates for good software design.

The Muse(W12)
Full applicationIn 2010 KMinshew worked on the national strategic plan for the introduction of the HPV Vaccine for the Government of Rwanda, including the development of a comprehensive plan for cervical cancer screening and treatment. As part of her role, she supported negotiations between the Rwandan Ministry of Health and Merck that led to a quadrupling in the amount of vaccine donated by Merck, from 500,000 doses to 2 million, and the introduction of the vaccine to Rwanda in April 2011 as the first sub-Saharan African country to offer it via the public health system. After millions of Americans lost their retirement savings in the 2008 economic downturn, ACavoulacos created the first holistic model that computed by age and income group how far from retirement security each demographic segment would be on the day they retired. With that complete picture into our (dire) future, she was able to model the effects of 10 potential laws being considered by a lobby in DC, to ensure that bills presented to lawmakers would in fact have the positive impact on our country that they hoped. The best of those are currently making it through Congress. Under MMcCreery's leadership, our previous startup PYP Media was named a Forbes' Top Website for Women and lauded for the sharp content and avid following it had earned. She was also the former Executive Editorial Editor of the Harvard Crimson.

Over those 7 months I've helped build and manage sites that have totaled over 200K users and utilized several API's (Facebook, Twitter, Twilio, LinkedIn, Mailgun, Amazon, iTunes, and Yipit - which I built my own wrapper for and open sourced). Bonus: I also got into Wharton after a suspension for selling weed sophomore year. \n\n At 17, worked my way into a full-time paid position at Zillow where I was in charge of developing their successful marketing and social strategy through blogs/FB/Twitter/etc as well as assembling a team to start a 500+ person technology education conference for real estate agents in Seattle, garnering 20+ sponsorship deals and kickstarting similar events in the region.

— advice from YC partners
Harjeet Taggar (Partner at Y Combinator)
SourcePay particular attention to the question asking which impressive things you’ve built/achieved. it’s the first question on the application i look at.
Ethan Fast (CS Ph.D. student at Stanford, YC alum)
SourceWe mentioned specific and verifiable achievements, the substance of which implied that we are determined people. You should try to avoid generalities.
Zain Shah (Data Scientist at Opendoor, YC alum)
SourceCome off as intelligent, capable, impressive in some manner. Bonus points if your impressive thing isn’t the startup but shows off your uniquely advantageous characteristics. E.g. Eastern region manager of the largest personal appliance repair shop chain in the world, Ralph’s, at only 25 years old.
Paul Graham (Co-Founder & Partner at Y Combinator)
SourceTo me this is the most important question on the application. It’s deliberately open-ended; there’s no one type of answer we’re looking for. It could be that you did really well in school, or that you wrote a highly-regarded piece of software, or that you paid your own way through college after leaving home at 16. It’s not the type of achievement that matters so much as the magnitude. Succeeding in a startup is, in the most literal sense, extraordinary, so we’re looking for people able to do extraordinary things.
Harjeet Taggar (Partner at Y Combinator)
SourceRealize the question asking about the most impressive things you’ve built or achieved is one of (possibly the) most important question on the form. Don’t answer with “This startup”, “I haven’t achieved anything impressive yet” or use it as an opportunity to show your sense of humour. We’re not looking for resume credentials here, examples of where you were determined to do something and stuck with it — regardless of the outcome — are impressive to us (since so much of what we’re looking for in founders is determination).
Paul Graham (Co-Founder & Partner at Y Combinator)
SourceWhen answering the question about the most impressive thing you’ve achieved, it’s not necessary to “focus on things that can be useful in a startup.” In fact that’s a common mistake. If you won an Olympic gold medal and can also write hello world in Ruby, we want to hear about the former, not the latter.
