Customer Success Lead

Instant is looking for a Customer Success Lead to help shape and scale our global Customer Success function. This is an exciting opportunity for a high-performing Senior CSM or team lead who has mastered the individual contributor role and is ready to step into leadership, own a bigger piece of the customer journey, and help build the CS function from the ground up.

You’ll be hands-on from day one - owning a portfolio of strategic customers while building the processes, playbooks and standards that enable the wider team to succeed. You’ll work closely with leadership, Product, Sales and Engineering to improve retention, drive adoption and unlock expansion across our growing customer base.

Ecommerce or ESP experience is essential. You’ll need to understand how ecommerce brands operate, what drives their growth, and the challenges they face across acquisition, conversion and retention.

Why Instant:

Instant is the world’s first AI-powered marketing manager built for ecommerce. Today, we’re quickly becoming the most important piece of technology to help the fastest growing brands on the planet to significantly scale their revenue - on autopilot. We're reinventing how brands bring their lost shoppers back to purchase through AI-powered email and SMS retention marketing. Our ambition is to be just as important and essential as Meta when it comes to helping an ecommerce brand scale.

This is a rare chance to help build a generational company at a true inflection point. Today, we service over 1,000+ of the worlds fastest growing brands like ThirdLove, David Protein, July Luggage and Meshki, with Instant’s products generating over 30% of our customers annualised revenue. We have strong product-market fit, adding more than $1M in ARR every month, 100M’s of shoppers interacting with Instant everyday, and the backing of world-class investors with over $35M raised from Blackbird, Hummingbird and Hubspot. We’re scaling fast.

The work is ambitious, the talent bar is high, and the opportunity for growth - personal, professional, and financial - is unmatched. Instant would be the fastest moving company you’d ever be apart of in your career. So, if you consider yourself ambitious, we invite you to join us!
