Hardened Soft

Hardened Soft is a full-cycle software development studio built around one rule: senior engineers only. More than 90% of the team is senior-level, so clients work directly with the people architecting and writing their code — not junior developers routed through several layers of account management.

We handle the entire lifecycle of a software product: requirements and architecture, custom software development, SaaS development, AI agent and automation development, cloud and DevOps engineering, QA and testing, MVP development, mobile app development, legacy system modernization, and software supply chain hardening (SBOMs, dependency auditing, and secure build pipelines). We also work as an outsourced or dedicated development partner for teams that need to extend their own engineering capacity without adding management overhead.

Every engagement runs on a two-week demo cadence, so clients see working software — not status decks — every single sprint. Response time on active projects is same-day, and every client keeps full ownership of their source code in their own repository from day one. Estimates are honest and fixed-scope by default; when a project's scope is genuinely uncertain, we say so up front rather than padding a fixed-price quote to cover the risk.

Beyond client work, Hardened Soft publishes original research on software cost, architecture, and engineering trade-offs — including a free SaaS Development Cost Calculator and an AI Agent Builder tool — and a growing blog covering real numbers on topics like MVP and SaaS build costs, outsourcing engagement models, legacy modernization strategy, and vendor lock-in risk.

Typical clients are startups building an MVP, growth-stage companies scaling a SaaS product, and mid-market or enterprise teams modernizing legacy systems or needing a dedicated senior engineering team without the overhead of a full in-house hire. Get in touch at contact@hardenedsoft.com.
