New research: Leading indicators of AI coding agent effectiveness
Span vs. Faros:
Engineering intelligence without the data project
Faros gives enterprises a flexible platform for custom analytics. Span turns fragmented engineering activity into a working intelligence system, with prompt-to-prod evidence behind every answer. See why modern engineering teams are switching to Span.
Why Span
A working intelligence system for engineering leaders

Span turns engineering data into trusted answers and next steps, without making customers design and maintain the analytics layer themselves.

Prove and improve AI impact
Connect agent traces and spend to retained code, delivery, quality, and cost. Surface the workflow improvements and environment fixes that improve results.
Get to a trusted decision faster
Start with a predefined engineering work model and ready-to-use workflows.
Prompt-to-prod visibility
Follow the complete agent session into the code and PR it produced, then inspect what happened through review and production.
Verify every result
Drill from any metric or evaluation into the underlying sessions, code, PRs, and tickets. Keep important conclusions grounded in evidence.
Reconstruct work from the work itself
Use code and activity to recover workstreams and relationships when source systems are incomplete. Depend less on customer-built mappings.
Support recurring engineering decisions
Use the same connected evidence for AI impact and investment decisions, without rebuilding the data model for every new question.

The Span Advantage
Why teams choose Span over Faros
Why teams choose Span over Faros
01
Less to build before you can act
Faros provides the components for a custom analytics system. Span starts with a working model of engineering, reducing the setup and interpretation work customers must own.
04
Know why AI performance differs
Faros can estimate system-level impact. Span adds task-level evidence that reveals how developers direct agents, where verification breaks down, and which environment fixes will help.
02
Get to the trusted decision faster
Fast ingestion is only the beginning. Span turns fragmented activity into a defensible answer leaders can use without first designing the schema or building the view.
05
Understand the work, not just the systems
Faros normalizes where work is recorded. Span also infers the meaning and relationships of the work itself, recovering context that was never cleanly represented in source systems.
03
Evidence from session to outcome
Follow AI-assisted work from the complete agent session into the code and PR, then inspect what happened downstream. Every conclusion stays connected to the underlying work.
06
Built to spread beyond the central team
Span gives each level of the organization role-ready answers without requiring a central analyst to configure every view. That makes the system easier to use repeatedly across engineering.
