Company Equity
Seattle startup Certivo has raised $4 million in seed funding to expand its AI-powered supply chain compliance platform. Suffolk Technologies led the round, with participation from Pioneer Square Labs, bringing total funding to $6 million. The company, which spun out of PSL in 2024, has developed what it calls a Compliance System of Record powered by an AI agent named CORA. The platform automatically collects and validates supplier documentation, tracks regulatory changes, and maintains real-time compliance records integrated with existing software. The 17-person startup targets manufacturers and companies in the "built world", helping them navigate regulations around PFAS, sustainability and supply chain transparency. Certivo is led by CEO Kunal Chopra, a former executive at Kaspien, Microsoft, Amazon and Groupon.
Seattle startup Prom.dev has emerged from stealth with $1.5 million in pre-seed funding to build a platform for sharing and discovering AI prompts. Pioneer Square Labs and Mayfield led the round. Founded in November by Heather Jackson, a former Amazon product leader, Prom transforms AI prompts into shareable artifacts that function like lightweight apps. Users can add design elements and input fields to their prompts and publish them for others to discover, use and remix—applying open-source principles to AI workflows. Jackson, who previously founded gaming publisher Astra Logical before its October acquisition, sees Prom filling a gap in the AI tools landscape. The platform is currently free, with plans for a GitHub-style business model: free for public sharing, with paid tiers for private team workspaces.
We raised $6M to build AI consumers that simulate real people—helping brands test products, packaging and messaging in minutes at a fraction of cost.
Seattle startup Envive, founded by ex-Amazon executives, raised $15 million in Series A funding, totaling $19 million since 2023, to develop AI agents for e-commerce. These autonomous agents provide personalized recommendations, customer support, and dynamic pricing while ensuring brand safety. This positions Envive in the "agentic era" of retail, promising efficiency and higher conversions.
