Hardened Soft

Hardened Soft is a custom software development studio built around one non-negotiable: software gets built by senior engineers who own it end to end, never handed off to junior staff after the sales call. We design, build, and ship custom software, SaaS platforms, AI agents and automation, and mobile applications for founders and engineering leaders who need delivery they can actually rely on.

Our services span the full lifecycle — custom software development, SaaS development, AI automation and agent development, MVP development, native and cross-platform mobile apps, cloud and DevOps, QA and testing, legacy system modernization, and software supply chain hardening — plus staff augmentation for teams that need to scale delivery without scaling headcount.

What the name promises, we build in: every engagement is treated as a security and reliability problem, not just a feature-delivery one. Legacy migrations use zero-downtime patterns like the strangler fig approach instead of risky rewrites. Software supply chain work — SBOMs, dependency provenance, governance for AI-generated code — is a dedicated practice, not an afterthought.

In practice that means fixed scope agreed in writing before we start, working demos delivered every two weeks instead of status reports, 100% source code ownership from day one, and a one-business-day response time if you email us. We also built our own SaaS Development Cost Calculator and AI Agent Builder so you can get real numbers before you ever talk to sales — proof over promises, the same way we approach the engineering itself.
