Top Tech Startups to Work For in 2027

StepsAI is one of the world’s leading agentic AI startups, building a unified AI brain for modern businesses. We create a single intelligent system that deeply understands your business—your website, products, systems, data, and internal knowledge—and turns that understanding into action. Instead of forcing customers or employees to navigate pages, tools, or silos, they simply ask. The AI answers, decides, and gets work done. One AI brain. Two powerful roles. For customers (external): StepsAI powers agentic AI across websites, e-commerce stores, and messaging channels. These AI agents answer questions instantly, recommend products, guide decisions, manage carts and orders, and resolve support—24/7. Conversations continue seamlessly across channels like WhatsApp and Instagram, without losing context or intent. For teams (internal): The same AI brain acts as a copilot for employees—helping them find information, understand documents, and complete tasks using the company’s own knowledge and systems. There’s no separate assistant to train. The intelligence that serves customers also empowers teams. Beyond chat, built to act. StepsAI doesn’t stop at conversation. Built-in workflows allow agents to trigger actions, update systems, and execute processes in a controlled, reliable way—whether supporting a customer or assisting an employee. Configure once, deploy everywhere. The result: One AI foundation that serves customers externally, supports teams internally, and drives real work across the entire business.

Learning for software developers is broken. Available options are boring, time-consuming, not relevant to everyone, or require the company to take a big productivity hit. We've designed a fast, effective training solution for tech teams that avoids those pitfalls. Targeted Capability Training is: - Core to how an engineering team operates, not a fringe add-on or an after-thought. - Learning that aligns with business priorities and changes what the team is capable of. And we’re called Skiller Whale because … well, our love of puns knows no bounds. Our mission is to change what tech teams are capable of. We’ve found the most effective way to accomplish this is through challenging, realistic exercises that can be explored and tackled in our interactive teaching model. We strive to be intelligent, playful learners, like our Orca, Ada (yes, we love a Lovelace reference). These principles define who we are, not only as a company providing a product, but also as a group of people working together. We believe that diversity makes us stronger and are dedicated to building a company that represents society as a whole. We value marginalised people’s safety over privileged people’s comfort. We value honest and open communication, and we believe that in order to foster an environment that enables this, it’s important that our team feel included, recognised and like they can bring their full selves to work.

Thera is changing that with an All-In-One HR platform for companies to hire, pay and support their remote teams. Through the Thera platform you're able to collect the needed compliance documents, execute locally compliant contracts, and facilitate payments in over 135+ different currencies.

Bunkerhill Health is a Sequoia-backed company on a mission to facilitate and streamline the AI development efforts of academic researchers and to increase the adoption of AI in healthcare in order to help doctors catch deadly diseases earlier. We have built a consortium of research institutions (Stanford, Johns Hopkins, UCSF, Harvard, etc.) whose researchers develop and validate AI algorithms seamlessly under our legal umbrella (weeks of setup time for a new project when using the Bunkerhill consortium, versus a year or more for projects outside the consortium). Bunkerhill then manages the FDA clearance and commercial sales process for the algorithms that these institutions develop and validate through the consortium. We’ve signed commercial contracts and deployed algorithms with some of the world’s leading health systems — UCSF, Mayo Clinic, Georgetown/MedStar, and several others. These algorithms help doctors identify patients earlier than has otherwise been possible, leading to better treatment outcomes (early clinical screening for heart disease, pancreatic cancer, etc.). We’re backed by world-class investors, including Sequoia, Felicis, SVAngel, Max Levchin (co-founder of PayPal and Affirm), and Y Combinator.
