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.

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.

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.

and more to be announced<br><br>When people think of Y Combinator, what often comes to mind first are the software companies that got their start with YC – companies like Airbnb, DoorDash and Stripe. But within the last 5 years, YC has funded over 500 healthcare and bio startups, 9 of which are now billion dollar companies. We’ve quietly become the largest seed stage funder of bio startups in the world.

Does co-founder matching work? It did for these three YC companies.

by Catheryn Li11/24/2021

“Co-founder matching saved my life.”

In August of 2021, Christina Czap, co-founder and CEO of Seer (YC W21), found herself badly in need of a technical co-founder. 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.

At the suggestion of her group partners at YC, Christina made a profile on YC’s co-founder matching platform. Three months and many calls later, Seer had a new CTO: Gal Vered, a former PM at Google.

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.

The co-founders of Seer (YC W21), Gal Vered and Christina Czap.

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.

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!

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.

Sequin (YC S21) co-founders, Vrinda Gupta and Mark Thomas.

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.”

Together, they went through YC’s batch this summer and raised $5.7M.

Kiwi Biosciences (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&D, but wanted a co-founder to help her build a consumer brand and commercialize the product.

Anjie Liu and David Hachuel, co-founders of Kiwi Biosciences (YC S21).

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.

They took a very structured approach to co-founder matching. Both founders answered all 50 questions posed in First Round’s co-founder questionnaire. 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.

Anjie and David worked remotely for four months and finally met in person after getting into YC. They went through YC and raised $1.5M.

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!
