Every AI SaaS tool is another renewal negotiation.

Every SaaS AI developer tool your team adopts creates a new vendor relationship: a new data agreement, a new security review, a new single point of failure, a new renewal negotiation. You’ve watched the AI tooling landscape shift three times in eighteen months. Standards that were "industry-leading" in Q1 are deprecated by Q3. Your team builds dependencies on platforms that get acquired, pivoted, or priced out. You need a standard you own, not one you rent.

Three layers. Three private repos. No vendor.

01 · DRILLS

Standardized Claude Code techniques

25 skills your org adopts as official AI usage policy. Delivered as a private repo your IT team controls.

02 · FLINT

Automated PR review with audit trail

5 GitHub Actions that enforce code quality standards consistently, with an auditable artifact trail on every pull request.

03 · TETHER

Production workflow integration

Connects your AI development pipeline to your existing engineering infrastructure without external SaaS dependencies.

Used by engineering organizations that needed AI development standards their legal team could review once and sign off on.

"What’s our data exposure?"

// the honest answer

The exposure question for enterprise AI tooling is data and dependency — what does the tool touch, where does data go, and what happens to your workflow if the vendor disappears? Review Stack has a clean answer on both: the repos are private, delivered to your GitHub organization, under your access controls. There is no ongoing SaaS relationship. There is no telemetry. There is no API call leaving your environment at runtime. You’re purchasing a set of documented patterns and automation scripts that your team runs inside your own infrastructure. Your legal team reviews it once. Your IT team controls access. There is no renewal, no price increase, no service degradation, no acquisition risk.
