| FinalDose develops programmable DNA therapeutics that target diseases at the level of their underlying genetic code.

When the therapeutic recognizes its programmed target, it undergoes a structural changethat activates a cellular kill switch to eliminate the diseased cell while sparing neighboring healthy tissue. This approach aims to address disease drivers that are considered undruggable by conventional protein-targeting methods. FinalDose initially applies its platform to cancers driven by complex mutations, using established human genetics knowledge to guide target selection and reduce research and validation cycles. | $500K / Pre-Seed / Jun 16, 2026 | ||
| Clawvisor provides a credential-vaulting gateway and authorization layer for AI agents that need access to external applications and APIs.

It keeps API keys and OAuth tokens in an encrypted vault, injects credentialsserver-side, and prevents agents from directly handling secrets. Clawvisor verifies each request using purpose-based authorization, blocking prompt-injection attempts, scope creep, and inconsistent actions before they reach provider APIs. The product offers human-in-the-loop approvals, risk scoring, and detailed per-task audit logs across connected services such as email, calendars, storage, messaging, version control, and payments. Clawvisor is available as a hosted cloud service and as self-hosted software that can run on private infrastructure for teams and organizations deploying agentic workflows. | $500K / Pre-Seed / Jun 16, 2026 | ||
