    Our company was in a unique situation, with an established codebase and a lot of internal knowledge. The engineers we worked with from Spartan adapted quickly to our code and subject matter and exceeded my expectations with their highly organized processes and passion for their craft. The onboarding process was tailored to our needs, and Spartan's strong, internal engineering community helped alleviate my concerns about not being able to provide enough resources for a remote workplace. I’m proud to call our Spartan engineers part of our team.

    The Spartan team is amazing! We had a very challenging ask for them in terms of technical rigor with limited available time, and they delivered. Their process is clean, well documented, and visible, so I always know what the team is doing and how. I really enjoy working with our team to the point that I feel like they are also members of our company.

    Highly recommend partnering with Spartan for your engineering and technical needs! They offer stellar talent across various areas and levels of expertise. Chan and his team go above and beyond in ensuring that your needs are met -- we appreciate their flexibility in helping us identify the right type of talent we need at what stage (Sometimes you don't know until you try!) as well as their flexibility in bringing onboard additional talent on a need basis (for ex: dev ops). They have strong SOPs and integration processes in place that make scaling up, down, and working with international teams easy and seamless. Would highly recommend it!

    Honestly, I don’t know what Spartan is feeding their engineers, but they’re ridiculously good and stupid fast. One day we give them specs, the next day it’s already running in prod. They somehow hit impossible deadlines, pivot on a dime, and still manage to explain what they’re doing in plain English. It’s like having a team of superheroes — minus the capes (though I wouldn’t be surprised if they had those too)

    Spartan’s founder, Chan, is an exceptional engineer—I often joke about cloning him. With Spartan, it seems he has. Their hiring standards are high, and the developers consistently deliver outstanding work quickly.

    Having spent my entire career working with in-house teams, I was initially hesitant to explore a new approach for my AI startup. However, after just a month of collaborating with the Spartan team, I was thoroughly impressed by their efficiency, proactiveness, and the quality of their work. Their ability to consistently deliver top-notch software engineering at an impressive speed has exceeded my expectations.

    After working with in-house teams my whole career, I hired development agencies for my Fintech startup. Building a great, reliable product was a struggle until I came across Spartan. Initially, I was skeptical, but within just a month of collaborating with the Spartan team, I transferred all my remaining projects to them. Their capacity to deliver high-quality software engineering at a rapid pace is a rare find.

    Using Spartan helped us double our engineering velocity right after Y Combinator. As a lean team moving fast, it gave us the talent and support we needed to scale without compromising on quality. It's like adding an excellent full-time employee in a matter of days.

    Spartan is the best off-shore team I've worked with. Each developer is top notch, really smart, can cover for one another, is curious and responsive. Our first task was for them to perform a difficult migration, which they executed without any issues. The firm's CEO, Chan, is a good sounding board and very fair. Camber looks forward to a close, fruitful partnership with Spartan well into the future.
