About
Doorvest is a San Francisco-based real estate investment platform that provides a fully managed end-to-end service for remote investors to acquire and own single-family rental properties without hands-on management. Investors select properties from Doorvest's curated inventory of renovated homes in target markets including Houston, Dallas, and Atlanta, and Doorvest handles the full lifecycle: property acquisition, renovation management, tenant placement, ongoing property management, and financial reporting. The platform is designed for busy professionals who want the wealth-building benefits of rental property ownership — appreciation, cash flow, tax advantages — without being landlords. Doorvest's revenue model includes property management fees and renovation margins, aligning the company's incentives with delivering high-quality rental homes that attract stable long-term tenants. Founded in 2018, Doorvest raised over $150M in debt and equity from investors including Y Combinator, Global Founders Capital, and Khosla Ventures. It competes with Roofstock, Arrived, and Turnkey real estate companies in the passive rental property investment market.

About
Armilla AI is a third-party AI quality assurance and warranty company that evaluates AI models for organizations deploying AI in regulated or high-stakes contexts — assessing models against EU AI Act and NIST AI Risk Management Framework requirements for risks including bias, hallucination, robustness failures, and adversarial vulnerabilities, then providing performance guarantees backed by insurance coverage from reinsurers Swiss Re, Greenlight Re, and Chaucer. Founded in Toronto, Canada, Armilla raised $6.81 million total including a C$4.5 million seed round in February 2024 from Mistral Venture Partners, MS&AD Ventures, Y Combinator, and its reinsurance partners.\n\nArmilla's model is unique in the AI governance market — rather than just providing compliance reports, Armilla backs its assessments with insurance warranty products. An enterprise deploying a third-party AI model can purchase an Armilla warranty that pays out if the model performs differently than assessed (fails on bias, accuracy, or robustness metrics), transferring AI performance risk to insurance markets that can price and distribute it. This insurance mechanism creates financial accountability for AI quality claims that audit reports alone don't provide.\n\nIn 2025, Armilla competes in the AI governance, risk, and compliance market with Credo AI, Arthur AI, and AI audit firms for enterprise AI risk assessment and compliance tools. The EU AI Act, fully applicable by August 2025 for high-risk AI systems, is driving enterprise compliance urgency — companies deploying AI in hiring, credit scoring, healthcare, and other regulated contexts need third-party conformity assessments. Armilla's insurance-backed warranty differentiates its offering from pure advisory competitors. The reinsurer backing (Swiss Re, Greenlight Re, Chaucer) provides both capital credibility and distribution through insurance broker channels. The 2025 strategy focuses on growing EU AI Act compliance assessments and expanding the warranty product coverage to more AI deployment use cases.
