Gearheart US

Gearheart builds operational B2B SaaS platforms for enterprise customers.

We get called in at two moments: the beginning of a serious build, or when an existing product has outgrown its early architecture. That means multiplying roles, breaking data models, workflows drowning in edge cases, or an SMB tool that suddenly needs to meet enterprise standards.

With 14 years of experience and over 80 products shipped, we have a particularly strong track record in GRC and Compliance SaaS, HR and Payroll SaaS, Workflow Automation, Low-Code / No-Code Platforms, Legacy Modernization, and AI Integration for B2B.

🚀Two examples of what that looks like in practice:

SmartSuite — a Work OS we built from scratch. It reached 7M+ users, hit $1.2M ARR within four weeks of launch, and raised $38M. Enterprise customers include Capital One.

Globalli — an HR and payroll platform with compliance logic spanning 125+ countries we helped to built from the ground up. Raised $15M+.

⚙WHAT WE ACTUALLY FIX:

Permission chaos — roles multiplying, access logic becoming brittle. We design RBAC systems that scale without forcing a rebuild later.

Collapsing data models — every new feature requires touching everything else. We build multi-tenant models designed to hold their shape as you grow.

Workflow complexity — business logic that's harder to reason about than the code itself. We implement engines that handle edge cases cleanly.

Enterprise readiness — audit trails, data segregation, compliance layers. We add this progressively on top of what you already have. No full rewrite.

AI readiness — scattered data and fragmented integrations blocking every AI initiative. We design the clean foundation that makes AI features actually shippable.

💡WHY TEAMS CHOOSE US:

Senior-only: engineers, product managers, and business analysts who think like owners. No juniors, no contractors learning on your budget.

Deep B2B SaaS experience: 14 years of seeing what breaks at scale, because we have built the products that scaled.

Global delivery at competitive rates: headquartered in Ukraine, with offices in San Francisco, London, and Tallinn.

AI-assisted development: we use Claude Code, Cursor, and Copilot as standard engineering tools. Faster delivery without cutting corners on production quality.
