Selfin

High-Level Overview

Selfin is building the first AI-powered neobank designed to unify and optimize users' financial lives through artificial intelligence. Their platform allows users to connect all their financial products—such as credit, investments, crypto, 401(k), and savings—into a single intelligent interface that provides personalized financial recommendations and automation. This approach aims to simplify banking, reduce fees, and improve financial decision-making by leveraging AI agents that act on behalf of users to manage and optimize finances automatically[2][3][4].

As a portfolio company of Y Combinator (Fall 2025 batch), Selfin operates in the fintech sector with a focus on consumer finance and AI-driven banking solutions. Their mission is to create personalized financial products and ultimately establish the first large AI-native neobank in the US, impacting the startup ecosystem by pushing innovation in financial services and setting new standards for user-centric banking experiences[3][4][5].

Origin Story

Founded in 2025 and based in San Francisco, Selfin was created by Paula and Joel, both aerospace engineering graduates with strong academic backgrounds from Imperial College, MIT, and Stanford. Paula previously worked at NASA and Bank of America, while Joel has experience at Boston Consulting Group. The founders were motivated by frustration with the fragmented and inefficient state of traditional banking, where users juggle multiple apps and tools without cohesive integration or intelligent assistance. This dissatisfaction led them to envision a banking platform with full contextual awareness of a user's financial situation, powered by AI to automate and optimize financial management[3][4].

Early traction includes acceptance into the prestigious Y Combinator accelerator program in Fall 2025 and securing $500K in pre-seed funding, signaling investor confidence in their vision and technology[4][5].

Core Differentiators

• AI-Powered Personalization: Selfin uses AI agents to provide personalized financial recommendations and automate management across all connected financial products, unlike traditional banks that offer siloed services[2][3].

• Unified Financial Platform: Users can link credit, investments, crypto, 401(k), savings, and more in one place, enabling holistic financial oversight and optimization[2][3].

• Founders’ Expertise: The founding team’s strong technical and financial backgrounds (aerospace engineering, NASA, BofA, BCG) provide a unique blend of analytical rigor and industry insight[3].

• Early Adoption and Support: Backed by Y Combinator and early investors, Selfin benefits from a strong startup ecosystem and mentorship, accelerating product development and market entry[4][5].

Role in the Broader Tech Landscape

Selfin rides the convergence of AI and fintech trends, where artificial intelligence is increasingly used to enhance personalization, automation, and efficiency in financial services. The timing is critical as consumers demand seamless, integrated financial experiences and as AI technologies mature to enable sophisticated financial agents. Market forces such as the rise of neobanks, growing adoption of crypto and alternative investments, and dissatisfaction with legacy banking systems create fertile ground for AI-native banking solutions like Selfin. By pioneering AI-driven banking, Selfin could influence the broader ecosystem by setting new standards for user experience and operational automation in finance[2][3][4].

Quick Take & Future Outlook

Looking ahead, Selfin aims to expand its AI capabilities and product offerings to become the first large-scale AI-native neobank in the US. Trends such as increasing AI adoption in consumer finance, regulatory openness to fintech innovation, and growing demand for personalized financial management will shape their trajectory. Their influence may evolve from a niche AI assistant platform to a full-service bank that redefines how consumers interact with money, potentially disrupting traditional banking models and inspiring further AI integration across financial services.

Selfin’s journey exemplifies the shift toward intelligent, user-centric banking, making it a company to watch as AI reshapes the future of finance[3][4][5].
