About Rosco Hill
Rosco Hill is based in New York, New York. He is co-founder and general partner of co:build.ventures (listed on Crunchbase as CoBuild Ventures) and co-founder and chairman of CoBrand. Crunchbase lists his education as the University of Toronto.
Crunchbase shows that he previously worked at Flywheel Digital as chief AI officer. PitchBook's profile adds that he served as an advisor at Thundermark Capital, co-founded Blend Labs and was chief executive officer at Perpetua. Lounge could not confirm those PitchBook roles against a second source, and PitchBook gives a San Francisco office address where Crunchbase gives New York.
Crunchbase credits him with four founded companies. CoBrand is the one with a public profile in the sources reviewed. Crunchbase describes it as a pre-seed software company in advertising and marketing technology, with the tagline "Superpowers for Creator Marketing". It lists Ben MacDonald, Laurier Mantel, Patrick Quaggin-Smith and Rosco Hill as founders, and co:build.ventures is one of its two listed investors.
Crunchbase records 3 investments, 2 portfolio companies, 0 lead investments and 1 exit, none of which was an IPO. The lack of lead investments suggests he has joined rounds led by others, though Crunchbase does not say so directly.
PitchBook classifies him as an individual angel investor with 3 investments. It gives his most recent investment as Nuvo, dated 8 May 2025, and also names Zest AI and Lenda. PitchBook's counts of portfolio companies and exits differ from Crunchbase's, so founders should treat the details as approximate. Individual check sizes, round terms and ownership stakes are not public.
His public track record includes AI-related roles as well as investments. He was chief AI officer at Flywheel Digital, according to Crunchbase. PitchBook lists Zest AI among the companies he has backed. Zest AI is a company PitchBook places in financial software, and PitchBook does not give a date or round for that investment.
He also co-founded CoBrand, a creator marketing software company, and CoBrand's investor list includes co:build.ventures, the firm where he is general partner. No public statement was found on his AI thesis, so none is described here.
Hill has not published a thesis, check size range or target geography in the sources reviewed. What the available records suggest is limited to the following:
Co:build.ventures appears as an early investor in CoBrand, which Crunchbase lists at the pre-seed stage. His PitchBook-listed investments are in financial services and financial software. His operating background covers advertising technology, marketing technology and AI.
