Yes. The institutional proxy-voting market has a few major categories: end-to-end voting platforms, proxy advisers/research providers, and specialized stewardship/voting agencies.
Provider
Main offering
Particularly useful for
ISS STOXX
End-to-end voting, governance research, recommendations, vote execution and reporting
Large global asset managers and owners wanting research + execution in one workflow
Institutions prioritizing operational scale and integrated vote processing
Minerva Analytics
Highly customizable voting policies, execution, split voting, governance/ESG research and stewardship analytics
Asset owners/managers wanting their own voting policies rather than a benchmark recommendation
Sodali & Co
More focused on proxy solicitation, shareholder engagement and meeting support
Activist/contested situations and shareholder engagement rather than routine institutional vote administration
The major choices
ISS STOXX is probably the closest thing to a full-stack institutional proxy-voting provider. Its platform combines governance research and recommendations with actual vote execution and disclosure; ISS says it covers more than 100 capital markets and cast 14.1 million ballots for clients in the prior year.
Glass Lewis is the other major proxy-adviser ecosystem. Its Viewpoint platform handles voting, research and reporting, while its pass-through offering lets asset managers give underlying investors choices among voting policies. It explicitly integrates with providers such as Broadridge, Proxymity and Tumelo for execution.
Broadridge ProxyEdge is particularly strong on the plumbing: receiving ballots, establishing voting rules, executing and reconciling votes, monitoring meetings, and producing regulatory reports. It can also incorporate third-party research and recommendations.
Minerva stands out if an institution wants a highly customized stewardship philosophy. It advertises 15,000+ configurable policy variables, custom voting policies, split voting, resolution-level rationales and coverage across more than 70 markets.
A useful way to think about the landscape
There are really two decisions an institutional investor can make:
“Who helps us decide how to vote?”
→ ISS STOXX, Glass Lewis, Minerva and other governance-research providers.
“Who actually gets the vote submitted, reconciled and reported?”
→ Broadridge, ISS STOXX, Glass Lewis/Viewpoint, Minerva and specialized voting infrastructure providers.
Many large institutions use multiple providers rather than choosing one—for example, obtaining research/recommendations from ISS or Glass Lewis while using an execution/processing platform such as Broadridge.
One particularly important trend is pass-through voting: asset managers are increasingly allowing their underlying investors to express voting preferences. Both Broadridge and Glass Lewis now offer infrastructure for this, while Vanguard's 2026 expansion of Investor Choice illustrates how significant the model has become.
If you're evaluating these vendors commercially, I can also give you a detailed competitive landscape of ~15 proxy-voting providers, including pricing model, geographic coverage, research vs. execution, APIs/integrations, target customer, and estimated market positioning.
Institutional investors—such as pension funds, mutual funds, and asset managers—rely on specialized proxy advisory, vote execution, and governance platforms to manage, automate, and report on global shareholder voting obligations.
