About Big Sisters AI

- According to CrunchBase, in January 2023, the startup secured private investments with a pre-money valuation of $10 million. The investor and deal size have not been disclosed. However, Big Sister is known as a portfolio company of Capital Factory, a Texas-based micro-VC firm whose average check size, according VCArchive, ranges from $10,000 to $25,000.
- In March 2024, the company opened an Early Seed round. At that time, Big Sister already counted seven paying clients, was piloting with a major enterprise customer, and was undergoing acceleration at Oracle & Plug and Play.

«Taking this victory into account, we’ve now raised $460,000. This provides a solid foundation for our $1M early-seed round, which is currently in progress. Our main focus is on the product and organic growth, so the $100,000 prize will serve as a strategic tool for us. We plan to invest it in development and, importantly, in strengthening ties with local partners, advisors, and clients in Dallas,» Valentyn Yaromenko told Scroll.media.
