Devyield

Solo developers and tiny teams can see commits, incidents, product behavior and revenue in separate tools, then struggle to remember which release preceded which business change. The supplied research confirms adjacent individual work-memory and enterprise engineering-analytics products, but did not find the exact solo-developer outcome journal in its reviewed set. One specific market signal could not be independently verified.

Devyield imports authorized release, error and business-event metadata and builds a shared timeline. It proposes associations using explicit windows and competing events, then drafts a weekly digest showing what shipped, what changed afterward and what remains unknown. The owner can correct mappings, exclude noise and annotate external influences.

A pull request preceding a revenue, conversion, support or error change does not prove it caused that change. Deployment, exposure, user behavior, commercial event and observed metric remain separate. The product suppresses lines-of-code and change-count rankings and begins with self-use by a solo developer, not employee monitoring.

The first release should connect only confirmed code and error sources plus one manually imported outcome source. It must not claim causal return on engineering, rank contributors, expose customer data, write back to source systems or pool private telemetry across users without explicit rights.
