A thesis-driven venture firm investing in early-stage companies in the digital identity ecosystem

PTB Ventures is a venture capital firm with a single thesis: digital identity. It invests in early-stage companies whose products are built on identity but reach well beyond a narrow use of it. The firm argues that identity underpins trust in social and economic life.
PTB looks for startups tackling large social problems such as financial fraud and inclusion, the security of communications and IT infrastructure, access to basic health services, and unlocking human potential. Its stated criteria include a large addressable problem, better user experience, security that lowers barriers to access, lower transaction costs and risks, and value for several network stakeholders.
