ApplySentinel
ApplySentinel is recruiting quality-assurance software that audits public job listings and job-to-apply paths for broken links, redirects, dead ends, and other candidate-blocking failures. It returns evidence and plain-language diagnoses using public web data only. It does not access applicant data, authenticate to an ATS, submit applications, rank candidates, or certify compliance. The product is pre-revenue, with no customers or claimed traction. The zero weekly-hour figure reflects current recurring customer operations because there are no customers; setup, commercialization, support, and transaction work are not represented as zero.

QuoteFollow
A sent quote should not disappear into an inbox. QuoteFollow gives a small service business a focused local workspace for seeing what needs attention, preparing factual follow-up copy, recording each manual touch, and deciding when a quote is won, lost, expired, archived, or still open. Its deterministic queue covers overdue, due-today, upcoming, snoozed, responded, and needs-decision records. Data stays in the browser and moves through versioned JSON backups or formula-safe CSV exports. QuoteFollow is pre-revenue software with no customers, revenue, traffic, or claimed demand. It does not send messages, connect to customer accounts, confirm delivery, or guarantee sales outcomes.

JobMargin Mini
The estimate says one thing. The completed job often says another. JobMargin Mini keeps both sides in one private closeout ledger so a service operator can trace movement in labor, materials, subcontractors, overhead, gross profit, and signed variance. It uses exact integer-based calculations, stores records in the browser, and exports versioned JSON backups or formula-safe CSV files. It is pre-revenue software with no customers, revenue, traffic, or claimed demand. It is not accounting, tax, payroll, estimating, or compliance software.

ProofPack
ProofPack turns operator-selected job facts and original files into a portable offline closeout package. The local-first workspace checks project records and attachments, surfaces duplicate-content hashes, and builds a ZIP with an offline index, deterministic JSON and CSV manifests, SHA-256 values, and the exact selected files. It is a pre-revenue software asset with no customers, revenue, traffic, or claimed demand. ProofPack organizes operator-supplied material; it does not certify authenticity, custody, workmanship, compliance, payment, completion, or legal sufficiency.
