Prior to Prime Movers, Justin invested as founding partner at TomorrowScale Ventures, a seed-stage venture firm. Before that, Justin served as a Venture Partner at Deep Science Ventures, a venture laboratory building optimal scientific ventures from scratch based in London, UK. Justin supported their portfolio of leading early-stage deep tech startups founded through the DSV program and located throughout the world in >20 countries.

Over the last 15 years Justin developed medicines from the bench through phase 2 clinical trials in various diseases areas with small molecules, antibodies, oligos and vectored vaccines across ten regulatory jurisdictions across four continents. Justin has been involved as a founder, investor, advisor or team member for more than a dozen biotech, nanotech and software companies.

Justin’s last role as an operator was to help build and oversee the portfolio of novel antibody therapeutics designed in silico and de novo (from scratch) against difficult targets by the brilliant team at Antiverse.

Prior to Antiverse, Justin served as Senior Director of Drug Development at Tetherex Pharma (now Moat Bio). Tetherex is a clinical-stage biopharma company developing novel biologics for the treatment of inflammatory, oncologic, and infectious diseases:

• SelK2 is a monoclonal antibody which recently completed dual Phase 2 studies in asthma and COPD.
• SC-Ad6-1, now being developed by Mayo/Tetherex spinout ‘Moat Bio,’ is a single-cycle vectored vaccine currently in phase 1/2a studies for SARS-CoV-2/COVID-19 via intranasal administration.

In his early career, Justin served as VP of Business Development and Operations at Accele BioPharma and Associate at Accele Venture Partners, a biotech accelerator and VC fund. At Accele, Justin worked on both sides of the table at a biotech venture accelerator and venture capital fund, identifying, funding, and managing novel therapeutic and diagnostic startups. Programs included: regeneration of beta cells in the pancreas for diabetes; regeneration of neurons and hair cells for hearing loss and balance disorders; discovery of fully human antibodies for cancer, infectious, and neglected disease treatments and diagnostics; and, antibiotics tackling multi-drug resistant Gram Negative organisms. Prior to that, Justin served increasing drug development roles at Altheus Therapeutics.

Justin also founded SnapLap Technologies (lab automation and machine vision AI for energy exploration and mineral analysis), Chorus Labs (productivity software, acquired 2015) and is an inventor and author on multiple patents and peer-reviewed publications.

In 2019, based on a passion for difficult scientific challenges and the companies that tackle them, Justin founded TomorrowScale. TomorrowScale Ventures partners with scientific entrepreneurs to create the future.
