Theta Lake
Scaling a UK Engineering Team to Match Business Growth
Theta Lake, a security and compliance platform for enterprise communications, has partnered with Propel since 2021. As its customer base grew, so did the need for a UK-based engineering team, and Propel led a focused hiring sprint across 2024 and 2025 to build it out.
As Theta Lake's customer base grew beyond the US, so did the technical capability needed to support it.
The Challenge
As Theta Lake's customer base grew, so did the need to support clients based outside the US, particularly those in time zones its US-based team couldn't properly cover. Headquartered in California with an additional office in New York, expanding into the UK became necessary to properly service that growing international base. That growth needed to be matched by technical headcount, to build, maintain and scale the engineering capability behind the platform.
The Solution
Propel has partnered with Theta Lake since 2021 and went through an extensive hiring sprint 2024-2025, working closely and consultatively with its engineering leadership on technical hiring. Weekly catch-ups were used to qualify each role and refine shortlists together as needs evolved, with all placements made on a permanent basis, delivered in step with the pace of Theta Lake's growth.
The Results
Propel placed 7 engineers across 5 roles, including senior backend, data science and cloud security positions, all supporting Theta Lake's expanding UK presence. The majority remain in the business today, and Propel continues to stay in direct contact with Theta Lake's engineering leadership beyond the active hiring periods.
