The lender said that alongside CEO Guy Harrington, Hilton had been instrumental in the growth of the business.
Hilton joined the firm at the end of 2017 ahead of its launch as director of lending, where he oversaw all aspects of the lending programme.
In his new role he will continue to support Harrington in devising and implementing the corporate strategy, including the launch of new products, building on his previous role.
Meanwhile, Johnson (pictured) has been promoted from head of compliance to chief operating officer.
He joined in 2018 soon after launch and has more than 15 years of experience in the short-term finance industry.
Johnson will oversee the implementation of the group’s business strategy alongside managing day-to-day operations, including leading the development of people, systems and processes frameworks to support its growing headcount.
Glenhawk completed more than £30m of lending in Q4 and has now lent over £150m across 213 loans with a gross asset value of more than £275m since launching in 2018.
To support this growth, the lender made 14 new hires in 2020, leading to a 35 per cent increase in the size of the team.
CEO Guy Harrington said: “Nick’s market leading understanding of the short term finance space has been key to understanding the needs of our borrowers and the evolution of our offering, while Damani has ensured that the business is aligned with the needs of our funding partners.”
