Yes. I found several firms that explicitly combine measurable development/engagement goals with a boundary that keeps the substance of participant–coach conversations confidential from the sponsor.
Strongest matches
- Skyline G — Particularly strong on measurement. It describes pre/post 360 assessments, goal-attainment surveys involving the leader/manager/HR sponsor, continuous competency tracking, and stakeholder alignment meetings. It says non-confidential data is shared with sponsors while coaching content remains confidential.
- Corporate Adventure — Has a very clear sponsored-coaching model: the participant and sponsor agree on specific coaching goals, progress against those goals is reviewed with the sponsor, but the firm says it reveals nothing about individual conversation content.
- Total Growth Coaching and Consulting — Uses development goals established at the outset, observable behavior changes/stakeholder input, optional 360 assessment, role-specific performance metrics, and quarterly reviews. Sponsor summaries focus on goal progress rather than session content.
- Collaborative Brain Trust — Explicitly distinguishes sponsor accountability from confidentiality: the sponsor receives progress against development goals, not a transcript, while session content remains between coach and client. Its process includes a close-out review against goals.
- The Wider Scope — Sets objectives and measures of success jointly at the beginning, establishes what will/won't be shared and review points, and then reports progress against the agreed goals while keeping coaching conversations confidential unless the participant consents.
- Onwards Consulting — Defines success with the business sponsor and tracks both quantitative impact and observable behavioral change. It explicitly says coaching conversations are confidential while high-level progress is shared with the sponsor.
One useful distinction
If by “engagement goals” you mean program-level engagement metrics—attendance, participation, completion, utilization, etc.—rather than leadership-development outcomes, inhouse.coach is an especially close fit. Its policy says sponsors receive participation/utilization reporting while individual coaching dialogue and personal reflections remain confidential.
For a procurement/RFP shortlist, I'd rank Skyline G, Total Growth, Corporate Adventure, and The Wider Scope highest because they make the two-part architecture especially explicit: pre-agreed measurable outcomes for sponsor accountability + protected coaching content for participant safety.
That model is also consistent with guidance from the International Coaching Federation, which describes sponsor reporting in terms of aggregate/program progress and goal completion rather than disclosure of individual coaching conversations.
If you tell me whether you're looking for large established firms (e.g., Fortune 500 scale), boutique firms, or firms that can administer this across a large leadership cohort, I can narrow this to 5–10 vendors and compare their measurement methodology, confidentiality terms, and likely pricing.
