StackOne

Multiplying focus and productivity time for a fast-growing HR tech software company

The Challenge

StackOne is a UK- and US-based HR tech startup, providing a platform that simplifies integrations between back-office, HR, and onboarding systems.

Founded by two experienced tech entrepreneurs, the business scaled rapidly, onboarding customers and employees across multiple locations while raising $20M+ from global investors.

With growth came operational pressure:

– Co-founders were spending excessive time managing emails, calendar invites, travel, and events
– Internal bandwidth was limited, making it difficult to focus on strategic priorities and core product development
– There was no dedicated support for managing daily administrative and operational tasks

Hiring a full-time executive assistant at this stage didn’t feel cost-effective, but the team needed a solution that would save time and scale with the business.

The Solution

StackOne partnered with Tyck to provide dedicated virtual assistant support. From day one, Tyck’s EA embedded into the business, managing:

Calendar scheduling and prioritisation, including complex time-zone-sensitive bookings, freeing up hundreds of hours for the founders each month
Email management, following up on dropped threads and highlighting key actions, reducing friction and missed opportunities
Travel, events, and project-based admin, improving operational efficiency and allowing leadership to focus on high-impact work
Proactive support, acting as a trusted partner who understands the business, anticipates needs, and helps the team scale without adding headcount

With an experienced EA familiar with fast-growing tech companies, StackOne gained a trusted partner who could proactively manage workflows and free the co-founders’ time. Tyck’s support enabled the team to focus on building the product and scaling operations, rather than juggling administrative burdens.

What they say

“Having someone dedicated to managing my calendar, emails, and admin has been incredibly helpful. It’s multiplied the scale at which I can work and allowed me to focus on the parts of the business that really matter. The support is proactive, trusted, and tailored to our way of working.”

— Romain Sestier, CEO and Co-founder, StackOne
