Roland Green Keeps Turning Lab Bench Problems Into Companies
Before Roland Green built antibody platforms, he wrote poetry, chased snow, and taught English in Prague. The same curiosity later turned a graduate-school workaround into NimbleGen - and now shapes how Invenra moves complex biology from bench to business.
Invenra Built an Antibody Factory. Then One of Its Molecules Reached Humans.
The Madison biotech spent years making two-target antibodies easier to build, screen and manufacture. Now a partner-discovered molecule is in a Phase 1 trial - and the operating lesson may be more reusable than the science.
Ability Biotherapeutics
Ability Biotherapeutics (also known as Ability Biologics) is a Montreal-based biotech founded in 2023 that engineers highly selective, immune-cell-modulating antibody therapeutics for cancer and autoimmune disease. Its AbiLeap discovery engine pairs continuously learning AI with one of the largest antibody-antigen interaction databases ever assembled to generate fully human, IgG-based multispecific antibodies that sense their environment and act only where intended - so-called logic-gated therapeutics. Backed by US$18M in seed capital led by Amplitude Ventures, the company is advancing a pipeline of immuno-oncology and autoimmune candidates toward preclinical readiness.
Tentarix Biotherapeutics
Tentarix Biotherapeutics is a San Diego biotech building conditionally active, multispecific biologics that switch on only at the cells where they are needed. Its proprietary stack - the VH-Select stabilized human VH scaffold, Tentacles multifunctional molecules, and the FunctionSeq mammalian-display screening engine - lets the company discover therapies with high cell selectivity and a wider therapeutic index across oncology, immuno-oncology, and autoimmune disease. Backed by Versant Ventures, Samsara BioCapital, Amplitude Ventures, and Gilead Sciences, and partnered with AbbVie and Gilead.
Hinge Bio
Hinge Bio is a clinical-stage biotechnology company in Burlingame, California, building next-generation antibody therapeutics on its proprietary GEM-DIMER platform. The platform engineers multivalent, multispecific antibodies that bind their targets cooperatively for dramatically enhanced potency. Its lead candidate, HB2198, is a B cell-depleting agent targeting both CD19 and CD20 with enhanced natural killer cell engagement, now in Phase 1 trials for systemic lupus erythematosus and lupus nephritis. The company raised a $30M Series A led by Point72 in January 2025.
