See the sphere. Shape the outcome.
Halo can help you identify and reach the individuals who shape outcomes — not just audience segments, but the real people with the power to influence decisions, policy, and perception.
Targeting Clarity
Individual level intelligence and precision
Flexible Reach
National engagement or hyper-targeting
Integrity
A defensible solution not a black box of records
A Unified Solution to Influence
Clarity on who matters. Confidence in how to reach them.
Tunnl's influential targeting with Halo is a tactical approach to connecting real-world relationships, evolving networks, and the entities around those who matter most to your campaign.
We didn’t just build this, Tunnl has been cultivating a perspective on influence for years. Because influential targeting requires more than reach.
-
It demands relevance. Halo connects you to who matters to your mission
-
It’s your pulse on who can influence, built for action, grounded in reality.
Flexible Targeting
Don't get locked into one mode of influence.
Reaching Opinion Makers and Outer Spheres of Influence
These audiences allow you to surgically deliver messaging to decision-makers, organizational leaders, or specific individuals where precision matters more than scale. Use this approach when you need direct engagement and clear action, recognizing that hyper-targeting around entities is not a full strategy but a tactical lever— one best executed with Tunnl as a strategic partner at the table.
Ideal for...
- Reaching Specific Stakeholders or Organizations: When your target is a clearly defined person or group — such as a CEO, policymaker, investor, or board member.
- Deploying a Grasstop Strategy: When you’re building momentum and credibility by influencing respected figures within a stakeholder network to generate support.
- Supporting Direct Advocacy or Policy Engagement: To create a “surround sound” effect ahead of a meeting, vote, or action — ensuring your message is seen by those who matter most.
Reaching Opinion Makers and Outer Spheres of Influence
These audiences allow you to expand reach, credibility, and soft influence by engaging trusted messengers within national and community-based ecosystems. Use this approach when you need to shape broad narratives and cultivate long-term impact, recognizing that outer-influence is not about immediate conversion but about creating the conditions for lasting persuasion.
- Brand or Issue Elevation: To elevate the visibility of a cause, brand, or organization at scale.
- Reaching National & Beltway Decision-Makers: To ensure policymakers, media, and institutional actors across Washington and key geographies - at the state and local level - see and hear your message.
- Measuring Awareness or Sentiment Over Time: When tracking shifts in perception, favorability, or engagement across a large, influential population.
- Engaging Active Community Members: To energize and inform already-active voices in relevant grassroots or advocacy communities.

Who Goes in the Spheres?
How Tunnl knows who to put in the Halo spheres
There is a two-lever process to this that ensures we capture everyone who is relevant. One part is automated and the other is hand-curated. We use our proprietary professional graph to identify and maintain dynamic relationships between individuals and entities based on their current organizations and their past work history.
We also know, for example, that if the person you’re targeting sits on boards, their fellow board members should be included. We can hand-curate and pull all of those individuals into our spheres of influence. We augment this with our own internal signals to map who is connected to whom—not just in their professional life, but in their social and neighborhood circles. We focus on influence that matters, not just social follows or weak-tie data.
HALO for insight
See what decision-makers see coming.
Turning influence into foresight, Tunnl's OPM Survey extends the power of Halo by capturing not just who matters, but what they think is coming next.
Each quarter, Tunnl surveys our proprietary audience of Policy Opinion Makers—the outer sphere of influencers who shape debate, signal regulatory direction, and define reputational risk.
With the option to add your own questions, you can measure how decision-shapers perceive:
- Emerging policy and regulatory change
- Shifts in brand perception and reputation
- Market dynamics and issue positioning
- Narratives likely to gain traction in media and politics
By combining these forward-looking insights with your Halo targeting, you can anticipate the environment your campaign will face—and move first.
