Customer.io raised our Series A

Startups often raise a lot of capital early. Large fundraising rounds shorten the time you have to thoughtfully build your business. In 2017, I talked about our approach, fundstrapping which still represents how we’re building the business today.

We have taken the time to do things right and Customer.io is ready to scale

In subscription software (SaaS) businesses, if you can keep the lights on, time can be your friend.

  • Time helps you figure out scaling issues a few years in when your largest customers start leaving because your performance is no longer good enough.
  • Time helps you address product issues from first principles rather than doing quick fix after quick fix.
  • Time helps you figure out scalable repeatable growth – something we were chasing for years before we got there.

Over 10 years in business, we’ve made a lot of mistakes. Taking the time to correct mistakes led to stronger product market fit, a deeper understanding of our customers, and greater confidence in our long-term vision.

As a result the business accelerated without using external capital. Customer.io ended 2021 profitable for the year with annual recurring revenue (ARR) of $29.9m, up 78% from a year ago.

The focus on innovation over extraction is what makes Customer.io an interesting place to work as well as a great company to bet on as a customer.

Customer engagement is a large opportunity we’re uniquely positioned to go after

We raised a Series A round of financing from Spectrum Equity

I chose Spectrum Equity because they showed me they understood the nuance of our business and are proven partners of founder-led businesses. They helped us create a deal that was right-sized for Customer.io and supports my focus on creating long-term value for all stakeholders. I’m thrilled we found a great match to join us on the next part of our journey.

Colin and team have consistently taken the long term approach to company building by being focused on product and customer experience over the last ten years. During that time they also have built a very successful hybrid self serve and sales assisted model which allows frictionless onboarding and an ability to seamlessly grow along with their customers. We have seen first hand how Customer.io has enabled their users to be more product centric in their growth and to unlock the value of their first party data to drive meaningful customer interactions.

We’re investing across the board—more heavily in marketing and engineering

We’re also (unfortunately) still the “best kept secret in marketing tech.” We’re scaling up our marketing efforts to address that. There is a massive community of 30,000 expert marketers using Customer.io and we want to better connect everyone both in real life and virtually.

This is just the beginning

Customer.io has a uniquely large opportunity to serve our customers who might be at the earliest stage of their life to being a publicly traded company. It has been a privilege to be on this journey with many customers who have been with us since the beginning and many long-tenured team members as well.
