    2017 Year in Review - Klaviyo

    We realized very early on that the problem wasn't convincing the people behind those irrelevant communications to care more about what they were saying. It was the opposite. In the conversations we had with marketers and ecommerce founders, we were floored by their dedication to their customers and the creative and ambitious experiences they wanted to create.

Klaviyo – Why Work With Us?


Before starting Klaviyo in 2012, we spent time at Google, Performable (acquired by HubSpot) and Applied Predictive Technologies (acquired by Mastercard) using data and technology to help marketers get smarter at many of the world’s largest companies.

Over the last four years, Klaviyo has grown from two people to a team of over 100 people in downtown Boston. From fast growing ecommerce stores to some of the world’s largest companies, we work with thousands of companies around the globe to send tens of millions of emails every day.

Bootstrapped and profitable from the start, in 2015, we partnered with Accomplice to allow us to go faster.


What We're Building

Email is the #1 communication channel between companies and their customers and users. At Klaviyo, we're building the best platform to send email. We believe creating relevant, beautiful, personalized emails should be easy.

Today, companies spend up to 80% of their time just creating and managing emails. Our mission is to change that and let marketers focus on what they do best, being creative and crafting amazing content their customers will love. From newsletters to targeted campaigns or every day transactional emails, Klaviyo is the intuitive email platform for creating, managing and measuring every email a business sends.



Klaviyo is changing how businesses send email.

What we can promise:

  • You'll be in the middle of a super high growth startup that's bootstrapped, profitable and working on building a lasting company and culture.
  • You'll work on projects that change how millions of people engage with their favorite brands and companies.
  • You'll be challenged and work with other people who like to be challenged and have a great time doing it.
  • You'll have fun, laugh and learn. Weekly lunch and learns, tech talks, Friday afternoon happy hours, stand up desks, latest laptops, unlimited snacks, games and team outings to the Red Sox, Lawn on D, go-kart racing and other fun spots in Boston.

Sound good? Drop us a line. We're always looking for great people to join our team.

    Too many interviews in the process, they make you do an assignment in which the instructions weren't that clear, I decided not to continue further in the process and that was that.
