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.
The primary service providers in this space include:
Institutional Shareholder Services (ISS) : The largest and most influential independent proxy advisory and governance solutions firm globally. ISS provides comprehensive global research, custom policy implementation, vote recommendations, and end-to-end proxy voting execution platforms for institutional clients managing thousands of meetings annually.
Glass Lewis : A prominent independent governance and proxy research provider. Glass Lewis offers institutional clients its Viewpoint end-to-end proxy voting platform, which handles policy management, automated voting execution, share recall tracking, and regulatory reporting tools like Form N-PX.[](https://www.glasslewis.com/investor-solutions/proxy-voting-solutions)
Specialized Proxy Solicitation & Advisory Firms : For high-stakes proxy contests, corporate transactions, or activist campaigns, firms like Georgeson, D.F. King , and Innisfree M&A work closely with institutional and corporate clients to secure strategic vote counts and manage specialized solicitation logistics.[](https://www.leadersleague.com/en/rankings/usa-best-proxy-solicitation-firms-2026)
If you'd like, let me know:
Are you looking for tools tailored to regulatory compliance (like Form N-PX)?
Institutional investors have several options for managing shareholder proxy voting, ranging from end-to-end voting platforms to governance research and specialized pass-through voting solutions. The right choice depends on whether you need to execute votes across global portfolios, automate voting policies, integrate with custodians, manage regulatory reporting, or give fund clients more control over voting decisions.

Particularly suitable for
Broadridge ProxyEdge
Voting operations, reconciliation and reporting
Multi-custodian institutional portfolios
Glass Lewis Viewpoint
Research, voting policies and disclosure
Stewardship-focused investment teams
ISS ProxyExchange
Research-integrated vote execution
Institutions using ISS research and recommendations
These are complementary rather than perfectly interchangeable products. For example, a firm might use ISS or Glass Lewis for voting research and a separate platform for vote execution. Availability of specific integrations, market coverage and features will depend on the provider and service agreement.
How to choose a platform
I would evaluate prospective vendors against six criteria:
Execution and reconciliation: Ability to submit instructions, confirm acceptance, detect rejected ballots and track voting entitlements.
Policy automation: Rules for applying internal guidelines, proxy-adviser recommendations and ESG or stewardship mandates.
Compliance and auditability: Complete vote histories, approval controls, audit trails and applicable regulatory reporting, including Form N-PX where relevant.
Integration: Compatibility with portfolio management, order management, custody, data and compliance systems.
Commercial model: Implementation costs, annual licensing, per-account or per-fund fees, and research subscriptions.
Pricing and detailed implementation requirements generally need to be confirmed directly with vendors.
My initial shortlist: For conventional institutional proxy operations, start with Broadridge ProxyEdge and ISS ProxyExchange. Add Glass Lewis Viewpoint if integrated governance research and policy management are priorities, Proxymity if global voting connectivity is central, and Tumelo if pass-through voting is a core requirement.
One question would help me narrow this down: Are you evaluating platforms for an asset manager or hedge fund voting its own portfolio holdings, or for a fund manager that wants to let its underlying investors direct how the fund votes? Those are different use cases, and the best shortlist changes accordingly.
