Soxton

AI-native legal platform Soxton emerged from stealth with $2.5 million in pre-seed funding led by Moxxie Ventures and with investment from Strobe, Coalition, Caterina Fake, and Flex.

Designed for in-house legal team use, the platform offers a natural language AI copilot, trained on startup data, for legal issues, and a library of pre-built contracts and clauses ready for editing by the AI, which can then brief attorneys.

Moxxie Founder Katie Jacobs said: "The combination of AI and human legal judgment is immediately beneficial for companies at the earlier stage, but is also strategic for growth stage founders that don't yet need to have a law firm on retainer.”
