Questions & Answers

As answered by people managing The Invoice Machine and OptyStack.

What's the story behind your product?

OptyStack's answer:

OptyStack was built around a problem that's become increasingly common: business units now control the large majority of SaaS spend, while IT and security teams โ€” who are ultimately accountable for compliance, renewals, and risk โ€” have comparatively little direct line of sight into what's actually being purchased and used. That blind spot tends to surface at the worst possible moments: during a renewal negotiation, a security audit, or when finance asks why the company is paying for four overlapping tools nobody remembers signing up for. OptyStack was created to close that gap, giving organizations one place to see, manage, and optimize their entire software stack before those surprises happen.

What makes your product unique?

OptyStack's answer:

OptyStack combines AI-powered SaaS discovery, spend optimization, and software governance into a single platform that helps organizations maximize the value of their SaaS investments. It automatically discovers SaaS applications, identifies unused and underutilized licenses, detects Shadow IT and Shadow AI, and provides actionable insights to reduce software waste. Unlike traditional software asset management tools, OptyStack follows a value-driven pricing model that enables businesses to start quickly with minimal upfront risk while paying based on the value delivered.

Why should a person choose your product over its competitors?

OptyStack's answer:

OptyStack combines a genuinely low-cost entry point โ€” free for up to 5 SaaS apps, with no credit card required to start โ€” with a savings-share pricing model that scales fairly as usage grows. This keeps the platform accessible for smaller teams while staying aligned with enterprise-level savings goals. It also treats shadow AI as a first-class category alongside traditional shadow IT discovery, which matters given how quickly employees are adopting AI tools like ChatGPT and other generative AI apps outside of IT's visibility. Many legacy SaaS management platforms are still catching up to that shift, while OptyStack was built with it in mind from early on.

How would you describe the primary audience of your product?

OptyStack's answer:

OptyStack is designed primarily for IT, finance, and procurement teams at mid-size to large organizations โ€” the people responsible for controlling software costs, managing renewals, and reducing risk from unsanctioned apps and AI tools. It's especially useful for companies where SaaS purchasing has become decentralized across business units, leaving IT and finance with limited direct visibility into what's actually being used, paid for, or exposed to risk.

Which are the primary technologies used for building your product?

OptyStack's answer:

OptyStack connects to and integrates with more than 100 SaaS platforms and identity systems, including Google Workspace, Microsoft 365, Slack, and SSO providers, to build a continuously updated, live inventory of an organization's software stack. This integration-first approach is central to how the platform pulls together spend, usage, and access data from across a company's tools into a single source of truth.
