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. WHY US: 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, $15M+ 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 --- Source: Agency Source, https://agencysource.com/agencies/gearheartio.
