Index.dev has acquired Hirebolt (Y Combinator S21)🚀

Hirebolt is backed by Y Combinator one of the world’s most recognized startup accelerators, with companies like Airbnb, Stripe, and Dropbox in its network. Founded by Alex Zhou and Lorenzo, Hirebolt built a high-performance matching engine designed for speed, accuracy, and scale.

Now, that technology moves into a much bigger space.

Together, we are evolving Hirebolt into an AI engineering capacity layer, designed to give companies faster, more reliable access to global software engineers and AI evaluators.

This means:
• Access to a vetted global talent network
• Instant search and matching powered by improved algorithms
• AI-augmented teams for flexible delivery
• Expert evaluation built into the process

This marks our second acquisition in six months, following Codemotion, and reflects our continued focus on building a platform for AI engineering delivery at scale.

More to come.

There are moments that make everything we do worthwhile.

Every year, the Index.dev team is proud to contribute to The Moldova Project’s Winter Project, bringing joy, wonder, and smiles to children from vulnerable families, and 2025 was nothing short of magical.

This past December, the Winter Project touched the lives of over 1,500 children across 42 villages, filling their days with laughter, surprises, cakes, dance, and the belief that Santa—and miracles—truly exist.

This year, we opened the campaign to our developer community and Codemotion, proving how powerful collective action can be.

Being part of this initiative inspires both pride and gratitude. The happiness on the children’s faces reminds us of the power of kindness and why we return to this project year after year.

A heartfelt thank you to The Moldova Project team, Victoria Morozov, and all the volunteers: your tireless work, empathy, and ability to coordinate such a massive effort (1,500 kids!) is nothing short of heroic. We are humbled to be listed alongside so many incredible partners.

To every Indexer who contributed this year and in years past—thank you. Your generosity plants seeds of hope. It shows children that the world can be kind, that miracles do happen, and that they truly matter.

Even the smallest acts of kindness can make a world of difference 💜
