The investment round was led by Angels in MedCity and Angel Academe.
"We are really excited to be starting the next phase of BeamLine and initiating our first in-clinic trials. Being part of Angels in Medcity and Angel Academe has offered us such diverse but relevant experience that has and will greatly accelerate our growth."
The retail analytics firm has raised new capital from Angel Academe and private investors to scale its operations.
"This is an exciting time for Clear Returns as investment is looking strong for 2016. The latest interest demonstrates the massive opportunity data in retail holds for the industry and how key influencers are now seeing this as a game changer, which will boost profits as customers keep more of what they buy"
The funding round was backed by a consortium including Angel Academe, Hambro Perks and Coral Reef.
"Angel Academe should be top of the list for any female founder looking for funding, their network and people are amazing. I hope more women will join them, so they can back more entrepreneurs like me."
The funding round completes an £850k raise backed by the women-focused angel network.
