Top Tech Startups to Work For in 2027

CannaBIZ Credit Association (CCA) is building the credit infrastructure for the cannabis industry. Our platform gives cannabis operators, brands, MSOs, and financial institutions access to industry-specific credit and payment data so they can make smarter decisions about who they do business with. CCA brings together billions of dollars in reported accounts receivable data from across the U.S. cannabis market, giving members tools to evaluate payment risk, identify collection activity, monitor customers, and better manage trade credit. With hundreds of members and many of the country’s largest cannabis operators contributing data, we’re building a network that gets more valuable as it grows. We’re a small, fast-moving team building something that hasn’t existed in this industry before: a true credit data network designed specifically for cannabis.

Kombo (YC S22) is building a unified API for HR, payroll and recruiting systems that saves engineering teams hundreds of hours by needing to integrate only one API instead of 50+. We raised $8M+, hit strong product market fit (0-> $4M+ ARR in 2-years) and are processing the equivalent data of ~10% of Germany's workforce. Culturally, we are looking for ambitious yet kind builders - we like to describe ourselves as a "SF startup but in Berlin".

Ultrassure builds AI software for insurers, reinsurers, brokers and investment funds operating in one of the world’s most complex industries. Our platform turns submissions, contracts and claims documents into information underwriters can act on. It helps teams assess opportunities, compare wording, check underwriting guidelines and identify risks across entire deals. Founded by a former reinsurance underwriter who managed billion-dollar portfolios, Ultrassure combines firsthand industry experience with modern AI engineering. We build around real workflows and work directly with clients to turn their feedback into product improvements. Based in Toronto, we’re a small team tackling substantial technical challenges: understanding complex documents, reconciling conflicting information and delivering reliable answers at scale. Join us to build software that experienced professionals use to make consequential decisions.

Ennote was founded by cloud security architects with over a decade of experience designing secure, distributed infrastructure environments for global enterprises across AWS and GCP. Across every architecture a pervasive vulnerability continuously emerged: engineering teams, faced with the overwhelming operational overhead of legacy vaults or the manual friction of unencrypted configurations, frequently bypassed approved systems to drop raw environment files directly into Slack channels and CI/CD code pipelines. This trend is not an operational discipline problem; it represents a fundamental platform architecture failure. When legacy security tooling slows down shipping velocity, developers inevitably bypass it entirely. For too long, the industry has forced companies into a binary choice: bureaucracy or chaos. Legacy vaults are powerful but require dedicated DevSecOps teams to configure and maintain. Conversely, simpler developer-focused utilities are user-friendly but lack native, real-time infrastructure automation delivery. This trade-off becomes exceptionally critical in the modern AI era, where the explosive growth of automated workflows, LLM pipelines, and machine identities demands a unified approach to security. Ennote eliminates this friction entirely. By seamlessly uniting human collaboration with Kubernetes-native machine automation, the platform establishes a single standard for enterprise secret governance. It fuses an intuitive team password vault for human workflows with a push-based, outbound-only gRPC engine that streams credentials directly into container runtime states in less than one second. This unified ecosystem bridges the gap between organizational identity and machine infrastructure, protecting all credentials under a verifiable, client-side encrypted, post-quantum zero-persistence architecture.

UtiliSave has developed a suite of proprietary software that uses intricate algorithms to capture, scrub, and parse massive amounts of data into meaningful information, imperative for a successful audit. This robust data analysis system allows UtiliSave to conduct more effective and thorough reviews resulting in more lucrative findings and the recovery of greater savings than other firms, year after year.

We help multifamily owners plan, deploy, and operate charging across their properties. Our approach connects infrastructure planning, load management, installation, resident support, and day-to-day operations under one accountable partner. That helps property teams avoid overbuilding today while making room for demand to grow. We’re a team of strategists, technologists, and operators who care about what happens after a charger goes live: residents can charge reliably, and site teams have someone to call when they need help.
