Overview

About Gearheart

Gearheart is a product development studio specializing in operational workflow-heavy B2B SaaS platforms — the kind where permissions, data isolation, and workflow logic determine whether the product actually holds up at enterprise scale.

We engage at the start of a build, or when a product has outgrown its early architecture: when roles multiply, new features require touching everything, or an SMB tool needs to move upmarket and suddenly requires audit trails, compliance readiness, and data segregation.

14 years, 80+ products shipped.

Strongest track record in GRC/Compliance SaaS, HR/Payroll SaaS, Workflow Automation, Low-Code / No-Code Platforms, Legacy App Modernization, AI Integration in B2B SaaS:

  • SmartSuite (Work Operating System) → Built from scratch. 7M+ users, $1.2M ARR in 4 weeks post-launch, $38M raised. Used by companies like Capital One
  • Globalli (HR and payroll platform) → Enterprise compliance logic across 125+ countries, built from the ground up, $10M+ raised.

WHAT WE HELP WITH:

  • Permission and access control architecture that scales.
  • Multi-tenant data models built for growth from day one.
  • Workflow engines that handle enterprise-level complexity.
  • Adding an enterprise layer to products moving upmarket.
  • AI readiness — clean data foundations that make AI features actually buildable.

HOW WE ENGAGE:

  • Custom Software Development: Full-cycle product development, from architecture decisions to production deployment.
  • Embedded Engineers: Senior engineers who plug into your team and work as part of it.
  • QA Systems & Test Automation: End-to-end quality assurance built into the process, not bolted on after.
  • Architecture Advisory: CTO-level guidance on data models, permissions, and system design.
  • DevOps & Infra Checkup: Audit and optimization of your infrastructure, deployment pipelines, and cloud setup.

The expectations for the project were set from start to finish. The team communicated well and deliverables within their control were met. Would definitely work with them again.

Gearheart were a real pleasure to work with. As a first-time, female tech startup founder I was particularly nervous about selecting the right partner and I'm so glad I chose Gearheart. From the beginning they were incredibly supportive, and thorough and guided me through each and every stage of the process with ease. The team has such a high standard and it was amazing to see the product finally come to life. Throughout the team delivered on time and within budget which was brilliant. At the end of the project (and still today because they support me with ongoing technical support!), it felt like I had an extended group of co-founders who genuinely cared about the success of my business. I think this is so rare, particularly when all of our interactions were virtual and it was an incredibly niche business in the parenting space! I would highly recommend working with them and will miss this project so much.

We hired gearheart to develop our internal credit system. Despite the language barrier, they can deliver their best work. I appreciate their openness and honesty. That is what i valued most working with an external vendor. They always take it to the next level for their work quality, and it feels like we can communicate easily with them, making it easy to collaborate

Working with Gearheart team is a wonderful and blessing journey for us. Not only because of their great skills but also Gearheart accountabilities and sense of ownership of the project. They always strive to deliver the project (and progress) on time. They also go the extra mile to understand more about the project and give suggestions or feedback to make the web/app better. As Gearheart put their heart to the project, it feels like we're not working with some vendor, but with an internal team.

Working with the Gearheart team has been a positive and effective experience. They have clear planning, a deep understanding of our needs, and a high level of responsibility. The team was always open to communication, always in touch, and provided demos and reports on time, which allowed us to interact and make adjustments to the workflow effectively. Regular meetings helped to solve the assigned tasks and identify new stages of cooperation.

We had the pleasure of working with Gearheart to develop our app, and the experience has been nothing short of exceptional. From the initial conceptualization to the final product launch, they have consistently demonstrated a high level of professionalism, expertise, and commitment. The development process was smooth and efficient. They kept us informed at every stage, ensuring that we were aligned with their progress. Their team's technical skills and attention to detail are evident in the app's flawless functionality and user-friendliness. Thank you for your dedication, expertise, and for helping us bring our app to life. We look forward to the opportunity to work with you again on future projects.

We hired Gearheart to develop the web application due to their high professionalism and extensive experience. Initially, we only handed over the front-end to them, but a month later we decided to delegate the back-end as well, as we were pleasantly impressed by their work. We had regular meetings where the Gearheart team showed us the overall progress, demo, and where we planned the next iteration. We had the opportunity to communicate freely with the entire team. For example, the developers were directly involved in the process. And they provided us with details and possible solutions to the technical tasks they were working on.

We work with private securities and investment banking. The Olivia project has been in development for over 10 years. It is very important for us that all processes are carried out in accordance with the procedure established by law. The team came up with a very flexible way to set up the workflow, we were able to fully automate the process of assigning tasks and reviewers, as well as go through the deal from start to finish without missing a single important step. Security is very important to us, the personal data of our customers and information about transactions are stored very carefully. We have repeatedly successfully passed the audit. Data security at the highest level. During the project, we carried out a redesign, changed the project management team from our side. Developers, testers, analysts and project managers have also changed. But, thanks to the internal organization of the company and the project documentation, all processes went quickly and without any difficulties

I have evaluated several companies, each of which I have met personally. Gearheart was my choice the moment I met them - we spoke the same language from the start. I really liked their attitude, their culture, their willingness to listen, their commitment to solving customer problems and creating the best product in their niche. We are building a game-changing work management platform. The Gearheart team has been there since day one. We have been working on a product for two years silently, until it went public in the beginning of 2022. The team has laid a foundation, the main architecture, and also developed all core modules of the system.
