## About

Tio Bioventures is a boutique venture creation firm focused on funding the advancement of biotechnology companies that are guided by its principles of employing rigorous, research-driven science to create first-in-class cancer medicines that improve survival and quality of life. Unlike a traditional venture fund, TIO Bioventures leverages its internal TIO Discovery and development engine to efficiently drive its portfolio companies through key catalysts with a ‘hands-on’ approach in partnership with its founding scientists. The TIO Discovery engine is a fully functioning organization, featuring drug discovery, R&D and early stage clinical development capabilities that provide deep support for TIO Bioventures companies as they move into further stages of development. Currently the firm has multiple portfolio companies in development including a clinical-stage oncology company, Treadwell Therapeutics, a biologics focused oncology company with lead candidates identified, and a differentiated T cell therapy company. TIO Bioventures takes a control shareholder position in each of its portfolio companies.

## Questions

### Who runs investment decisions at TIO Bioventures?

Co-founders Shane Burgess and Tak Mak lead investment decisions. Burgess serves as Managing Director and CEO of TIO-incubated Treadwell Therapeutics. Mak — a co-founder of Agios Pharmaceuticals and a leading immunologist at Princess Margaret Cancer Centre — provides scientific direction and access to academic networks.

### Is TIO structured as a venture fund or a company creation platform?

TIO operates as a company creation platform more than a traditional venture fund. It conducts translational research through its TIO Discovery Engine, identifies therapeutic candidates, and forms separate legal entities — such as Treadwell Therapeutics and Normunity — to advance them toward the clinic.

### What investment stages does TIO target?

TIO focuses on preclinical and early-clinical oncology programs. The firm funds the bridge between academic discovery and institutional Series A, often incubating programs through its internal discovery engine before a company is formally launched and management recruited.

### Which sectors does TIO explicitly focus on?

Oncology is the central focus, spanning cell-cycle inhibitors, immuno-oncology, and small-molecule drug discovery. The TCRypt platform, licensed from Princess Margaret Cancer Centre, represents a core technology band capable of generating multiple therapeutic candidates.

### How is TIO Bioventures related to Treadwell Therapeutics and Normunity?

Both are TIO-incubated biotechs. Treadwell, led by Burgess as CEO, develops cancer therapies from UHN-licensed targets. Normunity, run by former TIO R&D head Rachel Humphrey, M.D., pursues novel immunotherapies. TIO serves as the founding investor and operational architect for each.
