Top Tech Startups to Work For in 2026

600 Million Dogs is a nonprofit organization working to end the global suffering of stray dogs and cats by developing humane, science-based solutions to overpopulation. Our mission is to replace mass killing and painful surgical sterilization with a safe, simple, one-dose edible birth-control product called the “Spay and Neuter Cookie.” Around the world, hundreds of millions of stray animals struggle with hunger, disease, cruelty, and neglect. In many countries, overpopulation also contributes to rabies risk and public health challenges. We believe the solution must be humane, scalable, affordable, and accessible. Our team combines animal advocacy, scientific research, public education, and nonprofit outreach to create long-term change for animals and communities. We are looking for compassionate, mission-driven people who care deeply about ending animal suffering and helping build a kinder future.

We are a blockchain R&D studio, driven by our commitment to bridging (pun intended) the divide between foundational blockchains like Bitcoin and the thriving DeFi ecosystem. Our core expertise lies in solving intricate blockchain challenges through rigorous research in the realms of cryptography, game theory, and protocol design. Our mission is to make web3 simple and hassle-free for everyone. No intimidating complexities, just pure potential. We began our journey in 2022, with a previous experience of building two billion-dollar web3 projects, Ren and Rook under our belt. Our flagship product is the Catalog wallet (catalog.fi), a unique implementation of a multichain wallet that lets you use native bitcoin directly on any app. We also help power web3 projects like WBTC Garden (garden.finance) to become cross-chain seamlessly. We are a lean and fast moving team of like-minded people and are passionate about making our mark in the DeFi space.

Water is building AI that helps people accomplish goals, not just answer questions. Most AI systems are designed to follow instructions. They wait for the user to decide what to ask, what matters next, and what should be done. Water starts somewhere different: the goal. Tell Water what you want to accomplish. It builds the path, understands your progress and context, determines what matters next, and helps execute the work across AI, software, and people. The result is a new interface for getting things done: instead of managing prompts, tasks, workflows, and agents, the user focuses on the goal while Water helps direct the journey. We are starting with founder/operators — people with ambitious goals, small teams, and too many tools competing for their attention. The MVP is approaching launch, and we are building the initial founding team around a larger thesis: AI should not just be capable of doing almost anything. It should help people determine what is actually worth doing.
