Why C3 Metrics

Measurement that answers
to you — not the media.

C3 Metrics was built around a single organizing principle: your measurement partner should have no financial relationship with the channels being measured. Everything else follows from that.

Commercial ties to any of the 20+ channel categories we measure — every connection built for data access, not partnership

Independent by structure. No publisher relationships, no platform equity, no reason to shade results toward any channel.

Data quality is verified, not assumed. Ground Signal™ monitors and validates every signal before it enters a model — so independence isn't just a claim, it's auditable.

Partner model, not SaaS. Expert analysts plus proprietary AI — not a tool you figure out yourself.

Accountability as a practice. We manage expectations and results — and own both.

Independence Ground Signal™ Our Philosophy Leadership Methodology & Credentials Client Commitment Clients Who We Fit

The measurement problem no one talks about

Most attribution tools are built by companies with financial stakes in the channels they measure — platforms reporting on their own performance, or measurement vendors with publisher partnerships that create subtle but real conflicts of interest. The result is attribution that tends to over-credit the channels that benefit the tool provider.

C3 Metrics has no publisher relationships, no platform equity, and no paid media business. We are paid by our clients — exclusively — to give them accurate measurement. That structural independence is what makes objectivity possible, not just a stated value.

The attribution conflict of interest — compared
Platform Self-Reporting

Facebook measures Facebook. Google measures Google. Every platform has strong incentive to report its own contribution favorably — and the data to do it.

C3 Metrics

No platform equity. No publisher agreements. No financial relationship with any channel being measured. Paid exclusively by the advertiser to measure accurately.

Vendor-Publisher Partnerships

Many "independent" measurement tools have certified partner programs, co-marketing agreements, or equity relationships with major platforms — which create soft pressure on results.

C3 Metrics

Publisher integrations exist for data access only — not for commercial partnership. No certification program creates financial dependency on the channels we measure.

Measurement Vendors Under Changed Ownership

Measurement providers acquired by data brokers, media networks, or platform infrastructure companies carry their new owner's commercial interests into client programs — whether disclosed or not.

C3 Metrics

Independently owned and operated. No acquisition, no strategic investor with a competing measurement agenda. Independent ownership keeps the measurement philosophy honest — accountable to clients, not to a new owner's data strategy.

No publisher equity or paid media business

C3 Metrics earns revenue from one source: client measurement programs. There is no secondary business that creates financial dependency on the performance of any channel.

Channel-agnostic by design

Our models are built to find the truth about channel contribution, wherever it leads. If linear TV is underperforming, we'll say so. If social's self-reported numbers are inflated, we'll quantify it.

Accountability to the advertiser, not the ecosystem

When measurement results lead to hard budget conversations — cutting a channel, challenging a publisher's reported numbers, recommending a major reallocation — we don't have a reason to soften the message.

Transparent methodology, auditable results

Our models, filtering logic, and attribution methodology are documented and available for client review. We don't ask our clients to trust a black box — we explain how every number was produced.

Independence means nothing if the data isn't right

Structural independence removes the conflict of interest. But it doesn't automatically make the data accurate. Tags fail. Server-side feeds drift. Platforms change their reporting without notice. Any one of those problems — undetected — corrupts every model downstream.

Ground Signal™ is how we close that gap. It's our proprietary data quality and signal verification layer — continuously monitoring collection coverage across every channel, reconciling independently collected data against platform-reported numbers, and documenting every source, discrepancy, and resolution in a Signal Manifest™. Not just for our benefit. For yours: the Signal Manifest™ gives finance, audit, and C-suite a legible record of how your attribution data was produced and why it can be trusted.

This is what makes C3 Metrics' independence operationally meaningful rather than just structurally true. Any firm can claim they have no ties to the channels they measure. Fewer can show you a documented, auditable record of the data quality beneath the claim.

Continuous signal monitoring

Tag performance, S2S feed health, and platform-reported vs. independently collected data — verified in real time. Gaps detected before they reach the model.

Signal Manifest™

The primary deliverable of every Ground Signal™ cycle — a structured, auditable record of every data source, collection method, quality score, and reconciliation decision, readable by finance teams, auditors, and C-suite stakeholders.

Standalone or as a foundation

Ground Signal™ works as the data quality layer of a full Attribution Data Cloud program — or as a standalone signal audit for advertisers who want to verify their current measurement infrastructure without replacing it.

The right question isn't just "are you independent?" — it's "how do you know your data is right?" Ground Signal™ is the answer.

C3 Metrics operating principle

How we think about measurement — and our clients

The principles below aren't marketing language. They're the operational commitments that shape how we build models, staff accounts, and communicate results. We hold ourselves accountable to them.

Transparency and candor are non-negotiable

We tell clients what the data says — not what they want to hear. If a channel is underperforming, if the model reveals an uncomfortable reallocation opportunity, if a spend level has hit diminishing returns: we say it directly, with supporting analysis.

Transparency and candor are critical components of our offering — not just our values.

We own expectations and results — both

Success is measured by the gap between what we said would happen and what did. That means we're disciplined about what we commit to, and accountable when we fall short. Managing expectations is not spin — it's a responsibility we take seriously.

We are responsible for managing both expectations and results. We own our future.

Measurement serves decisions, not reports

Attribution data has no value sitting in a dashboard. Its value is realized when a media buyer reallocates a budget, when a CMO defunds an underperforming channel, when a brand moves dollars to where the model says they'll work harder. We build toward that outcome, not toward prettier reporting.

Data quality is the precondition for everything else

The quality of attribution output is directly proportional to the quality of the signal going in. Ground Signal™ — our proprietary data quality layer — monitors, reconciles, and validates every data source before any model runs. We've seen what happens when models run on unvalidated signals. Process matters before methodology, and that's not a philosophy — it's an architecture.

Partnership over product delivery

We don't drop a tool and walk away. Our account teams stay engaged — proactively surfacing insights, answering analyst questions, recalibrating models as markets change. The value of measurement compounds over time when there's expert human support alongside the technology.

We do what we say we will do

Commitments are commitments. Delivery timelines, model updates, analyst response times, data quality standards — if we said it, we mean it. The clients who stay with C3 Metrics for years do so because that consistency has proven reliable.

Chief Executive Officer

Greg leads C3 Metrics' sales, marketing, services, and product development functions, providing analytic support to clients and strategic guidance across product and execution priorities. Since joining as CEO in 2019, Greg has driven the sale and delivery of full omni-channel measurement programs to major advertisers across automotive, financial services, healthcare, and D2C. He has built and maintained the enterprise-grade infrastructure that attributes over 2 billion advertising events each month, and has overseen MRC Accreditation for Viewability and C3's positioning as the first company to pursue MRC attribution accreditation. Greg joined C3 Metrics with a multi-million dollar personal financial commitment to the company's mission.

Since then, C3 Metrics has doubled down through every disruption the industry has faced — the deprecation of third-party cookies, a pandemic-era reshaping of consumer media behavior, the consolidation of major measurement vendors into larger data infrastructure companies, and the emergence of AI-powered advertising channels. No pivot. No acquisition. The same focus, the same architecture, the same commitment to client-only accountability.

Built by people who understand both sides of the measurement problem

Greg's career is an unusually coherent arc for a measurement company CEO: strategy consulting at PricewaterhouseCoopers and Allen & Company, followed by 40 years of active advisory work through Cape Fear Advisors — developing deep expertise in automotive technology, SaaS, and data services by working with the companies that built the automotive retail technology ecosystem. That was followed by executive roles at Reynolds & Reynolds and Basho Technologies, and the chairmanship of DataSource, a platform serving distributed advertisers.

That combination — financial strategy, automotive technology depth, enterprise software operations, and advertiser-side infrastructure — directly shapes how C3 Metrics is run: as a high-integrity, results-accountable measurement partner, not a self-serve analytics product.

Core team disciplines
Client Support & Analytics

Dedicated account analysts providing proactive insight, ad hoc investigation, and model oversight for every program.

Data Science & Development

Engineering and ML teams maintaining the Attribution Data Cloud pipeline, model architecture, and tag infrastructure.

Proprietary methods. Third-party validation.

C3 Metrics has spent 15 years building measurement methods that competitors can't simply replicate. Several are proprietary to C3. One is independently accredited by the measurement industry's most rigorous certification body.

2.1 Billion Events Tracked — in a Single Month

C3 Metrics attributed 2.49 billion consumer touchpoints in February 2026 — the second-highest month in platform history, behind only August 2024. Never below 1 billion in any month since mid-2024. Across all programs, that is more than 23 billion events attributed over the last 14 months, and more than 54 billion since tracking began in 2022. At peak, 89 million events per day, processed through a two-stage AI pipeline with full fraud filtering. That signal density, at that continuity, is what enterprise-grade attribution infrastructure actually looks like.

Scale & Infrastructure

ORAC Funnel Taxonomy

C3 Metrics' proprietary four-position funnel classification — Originator, Roster, Assist, Converter — assigns every touchpoint a functional role in the consumer journey. This enables more precise fractional credit than position-agnostic models and surfaces channels that converter attribution systematically misses.

C3 Proprietary

BOS Offline Signal Detection

C3 Metrics converts offline channel exposures — linear TV airings, direct mail drops, and others — into digital attribution signals by measuring correlated lift in Branded, Organic, and Search traffic. This allows offline channels to participate in MTA as attributed touchpoints, not statistical proxies.

C3 Proprietary

Dual-Model AI Pipeline

Two sequential machine learning systems — an unsupervised model for signal quality and fraud filtering, followed by a supervised Bayesian model for consumer journey and channel interaction modeling. Industry-leading model accuracy is a direct result of this staged architecture.

C3 Proprietary

15 Years of Attribution Depth

Platform in market since 2011 — before multi-touch attribution was mainstream, before the deprecation of third-party cookies was a concern, before "AI-powered" became a marketing phrase. C3 Metrics' methods evolved through real programs, not theoretical models. That experience is embedded in the platform.

Platform since 2011

Cookie-Less Architecture from Day One

C3 Metrics' tag infrastructure was built without reliance on third-party cookies — not retrofitted after their deprecation. No PII is ingested at any stage of the pipeline. Privacy compliance is structural, not a policy layer applied to a legacy system.

Privacy by Design

The companies that choose independent measurement

C3 Metrics programs have included some of the most analytically sophisticated advertisers in their respective categories — organizations with serious internal data and analytics teams who chose an independent measurement partner precisely because they understood the conflict of interest in platform self-reporting.

The caliber of the client list is a direct reflection of what the platform is built to handle: large, complex, omni-channel programs where measurement accuracy materially affects budget decisions worth tens or hundreds of millions of dollars. Measurement-first independent agencies — the shops that lead with analytics rather than reach — bring their most demanding clients to C3 Metrics for the same reason.

We don't publish a client roster or display logos — not because we can't, but because confidentiality is a commitment we make to every program. What we can do is make you a direct introduction. Every client is a willing reference, and a prospect can choose who they want to speak with.

D2C, eCommerce & Enterprise Services

Full-funnel omni-channel programs for direct-to-consumer and B2B enterprise brands — including high-frequency marketplace platforms, subscription commerce, and major national fleet management and logistics programs.

The partner model — not the SaaS model

C3 Metrics is not a self-serve tool. It is a managed measurement program — which means our clients get expert human support alongside proprietary technology. That distinction shapes everything from how accounts are staffed to how quickly questions get answered.

Dedicated account analyst, not a ticket queue

Each client program is staffed with a dedicated analyst who knows the account, the channels, and the business context. Questions get answered by someone with access to your data and your model — not a generic support team.

Insights on media buying timelines

Attribution data is only useful if it arrives in time to influence a decision. Our delivery cadence and analyst responsiveness are calibrated to match the timelines on which media buys, flights, and budget decisions are made.

Proactive insight, not reactive reporting

We don't wait for clients to ask the right question. Our account teams proactively monitor program performance, flag anomalies, and surface reallocation opportunities — before a budget cycle forces the conversation.

Continuous model recalibration

Markets shift. Channels evolve. New platforms emerge. C3 Metrics models are continuously recalibrated as conditions change — so insights remain accurate over time, not just at program launch.

15%+ average advertising ROI improvement

Companies using C3 Metrics report an average 15% or greater increase in advertising ROI, and a 6× return on their attribution investment — driven by reallocation decisions the measurement program makes possible.

Two distinct entry points — one consistent standard.

C3 Metrics serves advertisers at two levels of measurement need. We're direct about fit at both — because programs that aren't ready for what we offer won't get the value, and we'd rather tell you that upfront.
