How to interview with YC with Founder of Terra (YC)
The founders of Terra (YC)

We got a chance to interview one of the hottest startups in YCombinator, Terra, which has raised millions in funding (2.8M$) and is an API that makes it easy for apps to connect to wearables. We wanted to know how he got started, how he got into y-combinator, what inspired him to build Terra, and where he sees the future. We also wanted to know their thoughts on making good founders and what are the key takeaways in building your own startup as well as getting into YC. After meeting at imperial and meeting them at another VC I had a personal relationship and think he is one of the best founders around.

Solid co-founders that you can trust and have a connection with

A co-founder that you can trust and has your back is essential: "You can build something fine doing it on your own. Maybe 2 people 3 people. But if you want to build world-changing companies and super impactful companies. You need to have a great team around you". Building a company is as much as having support as anything else we have learned.

Getting into YC

Its not easy to get into YC. A supportive community with real people who have done amazing things and can prove it with their exits keeps them going. From giving quality advice to helping out with any internal or external problem they may have YC has been amazing and would recommend it to anyone that can get in.

Choose your investors wisely

Make sure you choose your investors carefully as you are going to be with them for a long time. The best investors will let you go in the direction you want to take the company. Finding the right ones who see the same vision as you is crucial.

Building a company from scratch

When you think of an idea to prove that customers are willing to pay. Early on build a small MVP and prove that people are willing to pay for the product. Scaling requires a different set of skills and its important to hire the right people. In addition to this fundraising is a full-time effort so make sure you're ready for it. Focus on your clients. They cannot stress how important this is.
