Weekday is an Indian recruitment company that sources software engineers through referrals from other engineers rather than through job advertisements or agency databases. Its model pays working engineers to vouch for former colleagues they rate, turning informal knowledge about who is genuinely good into a searchable candidate pool that companies can hire from. Based in Bengaluru and backed by Y Combinator, the platform has layered AI screening and outbound sourcing on top of that referral network, and sells to startups and technology companies hiring in the Indian market.

MLabs is a software engineering firm specialising in functional programming and formal methods, working largely on blockchain protocols, smart contracts and high-assurance systems. Its engineers work predominantly in Haskell and related languages, which is unusual commercially and gives it a niche in projects where correctness has to be demonstrated rather than tested, particularly in the Cardano ecosystem. Registered in London and operating as a distributed organisation, it takes on protocol development, audit and formal verification work for clients whose systems hold value that a defect would put directly at risk.
