The role

In this role you will be the primary partner for our mid-market customers, ensuring they adopt our platform, realise value fast, renew successfully and grow over time.

Our clients are split across both EMEA and the US. In this position, you'd be responsible for supporting more of our US clients, meaning working hours would be roughly 10am - 7pm UK time. 

What you’ll be doing:

  • Own a portfolio of accounts, managing their onboarding, providing user training and handling their renewal
  • Focus on retention by driving product adoption, understanding and supporting their workflow, and identifying churn risks early
  • Proactively uncover upsell opportunities and partner with the relevant Key Account Manager to close them
  • Use Planhat to monitor customer health and prioritise customer interventions
  • Collaborate closely with Sales and Support to deliver a seamless customer experience
  • Be a customer advocate internally, sharing insights that help improve the product and roadmap
What we’re looking for:
  • Experience in Customer Success, Account Management or a similar role in a SaaS business
  • Proven track record of achieving and surpassing retention and expansion targets
  • Proficiency with CRM and CSM platforms, particularly Hubspot and Planhat
  • Comfortable working across different types of customers - from self-serve to large teams
  • Excellent communication and stakeholder management skills
  • Someone happy to support our US based clients when needed, likely 10am - 7pm working hours (UK time) 

What we offer: 

  • Stock options: We want everyone to feel motivated to do their best work, which is why we’re all owners.
  • Remote work: Enjoy extra flexibility with one full week of remote work per quarter.
  • Free lunch Thursdays: Build team connections over complimentary weekly lunches, available for both in-office and remote employees.
  • Wellness Wednesdays: We know working at a startup can be mentally tough, which is why we offer monthly expert-led sessions on meditation, yoga, and other well-being practices.
  • Great office location: Work from our centrally-located, pet-friendly office designed for comfort and team collaboration.
  • Birthday time off: Celebrate your birthday with an additional paid day off, if it falls on a weekday, separate from your regular vacation allowance.
  • Flexible annual leave: Enjoy 25 days of annual leave with the unique option to convert the 8 bank holidays into working days and boost your annual leave allowance to 33 days. Choose what works best for you.
  • Private healthcare: Access private healthcare through Bupa, including talk therapy and physiotherapy. We understand that everyone does their best work when they’re happy and healthy.
  • Retirement planning: We offer matched salary sacrifice pension with Smart Pension.
  • Cutting-edge AI technology: Be at the forefront of AI innovation, working directly with state-of-the-art AI technologies that form the core of our product.
  • Impact: As a rapidly expanding Series A startup, your contributions will have an immediate impact on our global development!


At Colossyan, we believe that diversity drives innovation and inclusion fosters a sense of belonging. We are committed to creating a workplace where everyone feels valued, respected, and empowered to bring their authentic selves to work. 

We actively seek to build a diverse team and encourage applications from candidates of all backgrounds and beliefs to apply to our open positions.

We strongly encourage individuals from underrepresented and/or marginalised identities to apply. If you need any accommodations for your interview, please email [email protected]
