Alt runs a marketplace where collectors buy, sell, value and vault trading cards, built on Ruby on Rails, React/TypeScript and PostgreSQL on AWS. A heavy scraping and data stack (Playwright, Puppeteer, Beautiful Soup, Spark, Dagster, XGBoost) plus repeated job-post focus on real-time pricing shows valuation models are the core engineering bet. It is moving off Selenium and Retool while adopting Cursor.
Alt is a San Francisco-based, privately held company founded in 2020 that operates a platform for collectible trading cards. Users can sell, buy, get valuations for, and securely store cards through the company's vaulting service. The broader goal is to treat alternative assets as investable, with lending and bidding experiences under active design. The company employs 51-200 people and hires in the United States, with engineering and design making up most of its current hiring.
Alt uses Ruby on Rails, React, TypeScript, PostgreSQL and Python on AWS (ECS, Docker), with Snowflake, Spark, Airflow, Dagster, scikit-learn and XGBoost for data and pricing models.
Alt is building a real-time pricing engine, redesigning its vault experience, designing a lending product and bidding surfaces, and enriching listings with vision and language models.
Yes. Hiring is accelerating and led by engineering and design, mostly at senior level, with additional roles in operations, data, sales and finance, all in the United States.
