End-to-end SFR investing; handles acquisition, renovation, tenant placement, and property management for remote investors; homes in Houston, Dallas, and Atlanta. Founded San Francisco.
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.
Serverless GPU cloud platform for AI/ML with Python-native deployment and per-second billing; developer-favorite scaling from zero competing with Replicate and Beam for AI compute.
Modal is a serverless cloud computing platform purpose-built for AI and machine learning workloads — providing on-demand GPU compute that scales instantly from zero with per-second billing, container management, distributed training support, and a Python-native developer experience that makes running ML workloads in the cloud feel as simple as running code locally. Founded in 2021 in New York City and backed by Redpoint Ventures and other investors, Modal has grown rapidly as AI development has accelerated demand for flexible, developer-friendly GPU infrastructure.\n\nModal's developer experience is its primary differentiator — engineers write Python functions decorated with @modal.function() and deploy them to the cloud with a single command, with Modal handling container building, GPU provisioning, auto-scaling, and execution. The platform supports training jobs that need distributed compute across multiple GPUs, model serving endpoints that scale to zero when unused (eliminating idle GPU costs), and batch inference jobs that process large datasets. The per-second billing model means developers pay only for actual compute time, not provisioned instances.\n\nIn 2025, Modal competes in the AI infrastructure market with Replicate, Beam, Banana, and major cloud providers' managed ML services (AWS SageMaker, Google Vertex AI, Azure ML) for serverless GPU compute. The market for AI-specific cloud infrastructure has grown dramatically as the number of ML engineers deploying models to production has expanded — traditional cloud providers require significant DevOps expertise to use GPU instances effectively, while Modal's Python-native approach reduces the barrier to entry. Modal has attracted a strong developer following among AI researchers and ML engineers building production AI applications. The 2025 strategy focuses on growing the developer community, adding enterprise features (dedicated GPU capacity, private networking, compliance), and expanding the hardware options available (H100 GPUs, custom accelerators).
