Rebill, an Argentina-based payment infrastructure company, has closed a $5.4 million pre-Series A round. Total funding since its 2020 founding now exceeds $9 million. The round includes a renewed investment from the founder and chief executive officer of Vercel, and a SpaceX executive investing personally. Existing backers include Tiger Global, Y Combinator, SV Angel, Soma Capital, and a Dropbox co-founder. Rebill lets merchants collect payments across borders as a local business would, without setting up a local entity. It operates in Argentina, Brazil, Chile, Colombia, Mexico, and the US, and counts Henry, Assist 365, and TripleTen as clients. The money will fund growth in current markets, deeper US operations, and two new lines: Rebill Treasury, for managing multi-currency funds, and Rebill Platforms, which lets software platforms offer payments under their own brand.

Databuddy Analytics, an AI-driven analytics platform, has raised $500,000 in Seed funding from Y Combinator. With backing from Maza Ventures and the a16z Scout program, its total funding exceeds $560,000. Founder Issa Nassar, who grew up in Palestine and dropped out of university, joined Y Combinator at 20. He is the youngest founder from the Middle East accepted into the accelerator. Databuddy's platform investigates conversion drops, customer friction, and product issues, then shows teams what changed and why. It serves more than 3,000 businesses a few months after launch. The money will fund deeper AI investigation tools, more integrations, targeted hiring, and onboarding and migration support.
