another YC Build Sprint through <a href=https://www.ycombinator.com/"https://www.startupschool.org//">Startup School</a>! It will begin on February 15 and end on March 14. Signups just opened, so you can <a href=https://www.ycombinator.com/"https://www.startupschool.org/sprint/register/">register for the sprint</a> now.</p>\n<p>The Build Sprint is an opportunity for intense focus on your startup or side-project for a specific period of time. For existing startups, this may involve a push towards launching a specific feature or reaching a certain milestone. For new founders, this is an opportunity to take the plunge and begin work on a project that excites you.</p>\n<p>At the start of the sprint, you’ll register your four-week goal. As the sprint progresses, you’ll be able to track your progress, get feedback from YC group partners and team members, and have weekly meetings with other sprint participants to provide accountability. The sprint culminates with the <a href=https://www.ycombinator.com/"https://www.ycombinator.com/apply/">YC application deadline</a>.</p>\n<p><strong>Getting feedback from YC</strong></p>\n<p>One consistent request we get from Startup School participants and YC applicants alike is more feedback from the YC team. For the upcoming sprint, we’re committing to provide more founder feedback than ever before. Each week, we’ll issue a public challenge to sprint participants and give personalized feedback to those who participate. We’ll also have weekly calls with YC partners and experts that will answer participant questions.</p>\n<p>Finally, in a first for YC, we’ll provide actionable feedback on 1,000<sup id=\"footnoteid1\"><a href=https://www.ycombinator.com/"#footnote1\">1</a></sup> YC S2021 applications submitted by sprint participants. Historically, we haven’t systematically provided personalized feedback on applications that don’t make it to the interview stage because of resource constraints. In the spirit of doing things that don’t scale, however, we’re going to get it done!</p>\n<p><strong>Want a sprint buddy?</strong></p>\n<p>If like many aspiring founders you haven’t gotten started because you haven’t found the right person to work with yet, we’d like to help! As part of Startup School, we recently launched a (still in beta) co-founder matching service. We expect most successful co-founder relationships will take months or years to build a strong foundation, but working on a Build Sprint project together is a great way to stress test a new relationship. If this sounds interesting to you, sign up for Startup School and <a href=https://www.ycombinator.com/"https://www.startupschool.org/cofounder_matching/">create a co-founder matching profile now</a>.</p>\n<p><strong>Let’s go</strong></p>\n<p>Build Sprint <a href=https://www.ycombinator.com/"https://www.startupschool.org/sprint/register/">signups are open now</a>. Looking forward to seeing you there!</p>\n<p>///</p>\n<p><b id=\"footnote1\">1.</b> If possible, we’d like to provide an actionable piece of feedback to everyone who completes the Build Sprint and submits a YC application. But we’re not sure how long that will take, so we’re only committing to provide feedback on 1,000 applications for now to be safe. <a href=https://www.ycombinator.com/"#footnoteid1\">↩</a></p>\n<!--kg-card-end: html-->","comment_id":"1104704","feature_image":null,"featured":false,"visibility":"public","email_recipient_filter":"none","created_at":"2021-02-02T01:00:23.000-08:00","updated_at":"2021-10-20T10:52:10.000-07:00","published_at":"2021-02-02T01:00:23.000-08:00","custom_excerpt":null,"codeinjection_head":null,"codeinjection_foot":null,"custom_template":null,"canonical_url":null,"tags":[{"id":"61fe29efc7139e0001a7117f","name":"Startup School","slug":"startup-school","description":null,"feature_image":null,"visibility":"public","og_image":null,"og_title":null,"og_description":null,"twitter_image":null,"twitter_title":null,"twitter_description":null,"meta_title":null,"meta_description":null,"codeinjection_head":null,"codeinjection_foot":null,"canonical_url":null,"accent_color":null,"url":"https://ghost.prod.ycinside.com/tag/startup-school/"},{"id":"61fe29efc7139e0001a71173","name":"YC News","slug":"yc-news","description":null,"feature_image":null,"visibility":"public","og_image":null,"og_title":null,"og_description":null,"twitter_image":null,"twitter_title":null,"twitter_description":null,"meta_title":null,"meta_description":null,"codeinjection_head":null,"codeinjection_foot":null,"canonical_url":null,"accent_color":null,"url":"https://ghost.prod.ycinside.com/tag/yc-news/"},{"id":"61fe29efc7139e0001a71180","name":"#startup-school","slug":"hash-startup-school","description":null,"feature_image":null,"visibility":"internal","og_image":null,"og_title":null,"og_description":null,"twitter_image":null,"twitter_title":null,"twitter_description":null,"meta_title":null,"meta_description":null,"codeinjection_head":null,"codeinjection_foot":null,"canonical_url":null,"accent_color":null,"url":"https://ghost.prod.ycinside.com/404/"}],"authors":[{"id":"61fe29e3c7139e0001a710a5","name":"Kyle Corbitt","slug":"kyle-corbitt","profile_image":"/blog/content/images/2022/02/kyle.jpg","cover_image":null,"bio":"Kyle Corbitt is a software developer at Y Combinator.

Seer, which raised $2.3M to help retail salespeople create shoppable Lookbooks, was receiving incredible customer interest and couldn’t keep up with the inbound demand.</p><p>At the suggestion of her group partners at YC, Christina made a profile on YC’s <a href=https://www.ycombinator.com/"http://www.ycombinator.com/cofounder-matching/">co-founder matching platform</a>. Three months and many calls later, Seer had a new CTO: Gal Vered, a former PM at Google.</p><p>Gal had been using co-founder matching since July. Although he was initially skeptical of the platform, he eventually met up with 46 potential co-founders, and found the perfect fit with Seer.</p><figure class=\"kg-card kg-image-card kg-card-hascaption\"><img src=https://www.ycombinator.com/"https://blog.ycombinator.com/wp-content/uploads/2021/11/asdfasd.jpeg/" class=\"kg-image\" alt loading=\"lazy\"><figcaption>The co-founders of Seer (YC W21), Gal Vered and Christina Czap.</figcaption></figure><p>We launched the co-founder matching platform earlier this year to help founders find their co-founders. When you sign up, you tell us about yourself and what you’re looking for, and we show you profiles that most closely match your ideal co-founder. If you message a candidate and they accept, we match the two of you.</p><p>Co-founder matching has also seen success with brand-new companies. Three pairs of co-founders met through the platform earlier this year, worked together on trial projects, became fully committed co-founders, applied to YC, and were accepted into the Summer 2021 batch!</p><p><strong><strong><a href=https://www.ycombinator.com/"https://www.sequincard.com//">Sequin (YC S21) is one of these companies. Vrinda Gupta had left her job after launching credit cards like the Chase Sapphire Reserve at Visa to work on a product to help women build credit. She spent a year working as a solo founder, and, in that time, raised a pre-seed and built an MVP. She knew she needed a technical co-founder who was mission driven, had fintech expertise, and was in it for the long haul.</p><figure class=\"kg-card kg-image-card kg-card-hascaption\"><img src=https://www.ycombinator.com/"https://blog.ycombinator.com/wp-content/uploads/2021/11/Sequin.jpeg/" class=\"kg-image\" alt loading=\"lazy\"><figcaption>Sequin (YC S21) co-founders, Vrinda Gupta and Mark Thomas.</figcaption></figure><p>That person was Mark Thomas. He had ten years of engineering experience at Paypal, cared deeply about gender equity, and spent six years as CTO of family-oriented startups. They had an instant connection and arranged to meet in person soon after. Vrinda recalls, “We met the day after we matched, and the day after, and then the day after that.”</p><p>Together, they went through YC’s batch this summer and <a href=https://www.ycombinator.com/"https://www.forbes.com/sites/geristengel/2021/09/15/debit-card-startup-builds-credit-for-women/?sh=6283b60b3c67\%22>raised $5.7M</a>.</p><p><strong><strong><a href=https://www.ycombinator.com/"https://www.kiwibiosciences.com//">Kiwi Biosciences</a></strong></strong> (YC S21) has a similar story. Anjie Liu started the company to solve her own pains with irritable bowel syndrome. She had a founding scientist to tackle R&amp;D, but wanted a co-founder to help her build a consumer brand and commercialize the product.</p><figure class=\"kg-card kg-image-card kg-card-hascaption\"><img src=https://www.ycombinator.com/"https://blog.ycombinator.com/wp-content/uploads/2021/11/kiwi.jpeg/" class=\"kg-image\" alt loading=\"lazy\"><figcaption>Anjie Liu and David Hachuel, co-founders of Kiwi Biosciences (YC S21).</figcaption></figure><p>When Anjie saw David Hachuel’s profile on YC co-founder matching, she knew that he was “exactly what [she] was looking for.” David had previously sold a startup in the same space, and was immediately interested in her idea.</p><p>They took a very structured approach to co-founder matching. Both founders answered all 50 questions posed in <a href=https://www.ycombinator.com/"https://proof-assets.s3.amazonaws.com/firstround/50 Questions for Co-Founders.pdf/">First Round’s co-founder questionnaire</a>. They found deep alignment on “all the important things” (conflict resolution, vision for culture, etc.). When their month-long trial ended and it came time to say go or no-go, the decision was easy.</p><p>Anjie and David worked remotely for four months and finally met in person after getting into YC. They went through YC and <a href=https://www.ycombinator.com/"https://techcrunch.com/2021/10/14/kiwi-bio-aims-to-free-irritable-bowel-syndrome-sufferers-from-restrictive-diets//">raised $1.5M</a>.</p><p>We’re ecstatic about the companies who met through our co-founder matching and we’re excited to see the platform continue to grow and support more awesome founders in the future!</p><p>Looking for a co-founder?

It was hard to be taken seriously by investors if you didn’t have an MBA or years of experience in business or tech. To get a sense of how many startups were in the world, look at TechCrunch in 2005. It published about 40 company launches per month, and YC itself only got a couple hundred applications for its first batches.</p><p>The world has changed since then. Today we get tens of thousands of applications per year. On any given day you can look on Product Hunt and see dozens of new companies launch. Taking a chance and starting a startup is not the foreign concept it once was. While it has become more common for people around the world to start startups, there are many more who could consider startups as an option. For example, lots of folks choose a career in finance or as an engineer at a big company without considering other options. Whether you know you want to become a founder or are more interested in finding a job at a startup, we want to equip you with the best resources for getting started.</p><p>In this guide, we’ll discuss why you should think about starting a startup and why you should consider not starting a startup. We’ll also talk about what you should do in college and walk-through some tips for applying to Y Combinator. And if it turns out being a founder isn’t for you, we’ll talk about how to choose the right company and the benefits of working at a startup.</p><p><a href=https://www.ycombinator.com/"https://www.ycombinator.com/library/D0-startups-for-students-guide/">Read the Startups for Students Guide here</a>.</p>","comment_id":"61f5f94feb74f90001a95776","feature_image":"/blog/content/images/2022/01/Startups-for-Students-Guide.png","featured":false,"visibility":"public","email_recipient_filter":"none","created_at":"2022-01-29T18:34:55.000-08:00","updated_at":"2022-02-01T16:22:58.000-08:00","published_at":"2022-01-18T09:00:00.000-08:00","custom_excerpt":"In the past two years, we’ve met over 6,000 students during our virtual outreach tours.

YC Build Sprint Winter 2021

by Kyle Corbitt2/2/2021

We’re delighted to announce the launch of another YC Build Sprint through Startup School! It will begin on February 15 and end on March 14. Signups just opened, so you can register for the sprint now.

The Build Sprint is an opportunity for intense focus on your startup or side-project for a specific period of time. For existing startups, this may involve a push towards launching a specific feature or reaching a certain milestone. For new founders, this is an opportunity to take the plunge and begin work on a project that excites you.

At the start of the sprint, you’ll register your four-week goal. As the sprint progresses, you’ll be able to track your progress, get feedback from YC group partners and team members, and have weekly meetings with other sprint participants to provide accountability. The sprint culminates with the YC application deadline.

Getting feedback from YC

One consistent request we get from Startup School participants and YC applicants alike is more feedback from the YC team. For the upcoming sprint, we’re committing to provide more founder feedback than ever before. Each week, we’ll issue a public challenge to sprint participants and give personalized feedback to those who participate. We’ll also have weekly calls with YC partners and experts that will answer participant questions.

Finally, in a first for YC, we’ll provide actionable feedback on 1,0001 YC S2021 applications submitted by sprint participants. Historically, we haven’t systematically provided personalized feedback on applications that don’t make it to the interview stage because of resource constraints. In the spirit of doing things that don’t scale, however, we’re going to get it done!

Want a sprint buddy?

If like many aspiring founders you haven’t gotten started because you haven’t found the right person to work with yet, we’d like to help! As part of Startup School, we recently launched a (still in beta) co-founder matching service. We expect most successful co-founder relationships will take months or years to build a strong foundation, but working on a Build Sprint project together is a great way to stress test a new relationship. If this sounds interesting to you, sign up for Startup School and create a co-founder matching profile now.

Let’s go

Build Sprint signups are open now. Looking forward to seeing you there!

1. If possible, we’d like to provide an actionable piece of feedback to everyone who completes the Build Sprint and submits a YC application. But we’re not sure how long that will take, so we’re only committing to provide feedback on 1,000 applications for now to be safe.
