# How to Choose the Best Marketing Agency for Companies Scaling to $100M

> A practical guide for CMOs and revenue leaders choosing a marketing agency to support growth from $20M to $100M. Evaluation criteria, questions to ask, red flags and a scorecard.

Scaling from $20M to $100M is where marketing turns from a set of campaigns into revenue infrastructure. Revenue targets double, headcount grows, and the board looks harder at attribution. The right partner at this stage builds the system that carries you to nine figures, and this guide shows you how to find it.

At this stage your agency is a growth partner, not a vendor. Picking well protects budget, time and runway.

According to [Gartner's 2024 CMO Spend Survey](https://www.gartner.com/en/marketing/insights/cmo-spend-survey), marketing budgets as a percentage of company revenue dropped to 7.7% in 2024. With every dollar under more scrutiny, the selection process deserves the same rigor you apply to a senior hire.

AI raises the bar further. CMOs are now deciding whether [agencies are worth it at all](https://www.gartner.com/en/newsroom/press-releases/2025-05-12-gartner-2025-cmo-spend-survey-reveals-marketing-budgets-have-flatlined-at-seven-percent-of-overall-company-revenue). Generative AI gives in-house teams real leverage, so the partners worth hiring are the ones using AI to ship faster and spend their time on the work a model cannot do.

Here is what to evaluate, the questions to ask, and a simple scorecard to compare finalists.

## 1. Look for Agencies That Speak Revenue, Not Just Metrics

Impressions, click-through rates and traffic are useful diagnostics. As you scale toward $100M, the numbers that matter are pipeline contribution, cost per qualified opportunity and marketing-sourced revenue. Ask every prospective agency how their work connects to those outcomes, and ask them to show you where the numbers come from.

The right partner understands your CRM, your sales cycle and your revenue model, whether that is ARR, transactional or contract-based.

**Questions to ask:**

- Which CRM fields and reports would you use to prove your impact?
- How do you define a qualified opportunity, and who signs off on that definition?
- What do you report weekly, and what do you report monthly?

## 2. Demand Proof of Scale

Helping a $5M company reach $10M is a different job from scaling marketing infrastructure for a company approaching nine figures. Ask for case studies that match your revenue stage and complexity, not just your industry. At this level you need different architecture, different spend management and different attribution models than at earlier stages.

**What good proof looks like:** a written case study with the starting point, what the team actually built, the timeline, and how results were measured. Ask to speak with a reference client at a similar stage.

## 3. Evaluate Their Strategic Depth and Execution Capability

Execution is the baseline. What separates strong partners at this revenue level is strategy they can also ship. Can they challenge your channel mix? Do they bring a point of view on where your category is heading? Do they spot gaps in your funnel before you ask? You want a team that works like an extension of your leadership and then builds what it recommends.

**Questions to ask:**

- Walk us through a time you told a client to stop spending on a channel. What happened next?
- Who on your team writes the strategy, and who executes it? Are they the same people?
- What would you change in our current plan in the first 90 days?

## 4. Assess Their Cross-Channel Coordination

At scale, no single channel drives growth in isolation. Paid media amplifies organic content. SEO informs messaging. Email nurtures the pipeline generated by events. A capable [B2B marketing agency](/b2b-marketing-agency) at the $100M stage understands how these channels feed each other and runs integrated programs instead of siloed campaigns.

**Illustrative example:** a company runs [paid search with one vendor, SEO with another](/blog/stay-ahead-of-the-game-use-sem-and-seo-to-outshine-the-competition) and the website with a third. Paid search sends traffic to a landing page the SEO vendor never sees, the web vendor changes form fields without telling anyone, and attribution breaks quietly. One partner that owns landing pages, tracking, CRM wiring and campaigns removes those handoffs.

## 5. Scrutinize Their Reporting Infrastructure

Fast-growing companies need near real-time visibility into marketing performance. Before you sign, ask to see the dashboards and reporting cadence the agency runs for current clients (with client names hidden). A monthly PDF alone is not enough. You need weekly performance reviews, clear KPI ownership and reporting tied directly to revenue targets.

**Check the plumbing:**

- Is reporting built on your CRM data, or on platform-reported conversions?
- Who owns tracking, UTMs and form-to-CRM mapping?
- What happens to dashboards and data if the engagement ends? You should own your accounts and data.

## 6. Vet for Cultural and Operational Fit

The best relationships at this stage run on candor. [HubSpot's State of Marketing research](https://www.hubspot.com/state-of-marketing) consistently points to sales and marketing alignment as a driver of better results, and you need the same alignment from an outside partner. Look for people who will tell you when a campaign is not working, push back on misaligned expectations and work inside a fast-moving team without adding friction.

**Signs of good fit:** they ask about your sales process early, they want access to sales calls or CRM notes, and they are comfortable working in your Slack, your project tool and your accounts.

## 7. Understand the Engagement Model and Commercial Terms

Agencies package work in very different ways. Know which model you are buying before you compare prices.

- **Retainer for a defined scope:** predictable cost, best when the work is ongoing and well understood.
- **Project fee:** good for a website rebuild, CRM migration or a tracking overhaul with a clear finish line.
- **Embedded team or team augmentation:** the partner works inside your team on your priorities, useful when your plan is solid but capacity is short.
- **Performance-linked fees:** sound attractive, but only work when both sides trust the same attribution data.

Ask who will actually work on your account, how much of their time you get, and how scope changes are handled. Confirm that ad accounts, analytics properties, CRM and website code sit in your name.

## Partner, In-House Hire or Both?

Before you compare agencies, decide what you actually need from outside the company. The answer shapes the whole search.

**Hire in-house when** the gap is one role you will need for years, the work depends on deep product knowledge, and you have a leader with time to manage the hire. A demand generation manager or a marketing operations lead often fits this pattern.

**Bring in a partner when** the gap spans several disciplines at once, such as tracking, CRM, paid media, content and the website, or when you need senior capability faster than you can recruit it. A partner also helps when the work is bursty, like a rebuild or a migration, and does not justify a permanent seat.

**Use both when** your internal team owns strategy and priorities but is short on capacity or specialist skills. In that model the partner embeds with your team, works in your tools and reports into your leader.

Whatever you choose, write down who owns each outcome. Ambiguous ownership is the most common reason agency relationships stall at this stage.

## Red Flags to Watch For

- Results reported only in traffic, impressions or rankings, with no link to pipeline
- A senior team in the pitch and a junior team on the account
- Ad accounts or analytics owned by the agency instead of by you
- Long lock-in contracts before any proof of work
- No questions about your sales process, CRM or ideal customer profile
- A plan that looks the same as the one they would give any other company

## A Simple Agency Scorecard

Score each finalist from 1 to 5 on every line, weight what matters most to you, and compare totals. The weights below are an example to adjust, not a standard.

| Criterion                              | Example weight |
| -------------------------------------- | -------------- |
| Revenue and pipeline fluency           | 25%            |
| Proof of work at your stage            | 20%            |
| Strategy plus execution in one team    | 15%            |
| Cross-channel and technical capability | 15%            |
| Reporting and data ownership           | 15%            |
| Cultural and operational fit           | 10%            |

Run the scorecard with your head of sales and your finance lead in the room. Agreement on the score is a good preview of how the partnership will run.

## How to Run the Selection Process

1. **Write a one-page brief.** Revenue goal, current funnel numbers, team, tools, budget range and the problems you want solved.
2. **Shortlist three or four partners.** Fewer wastes leverage, more wastes your time. If you run on HubSpot, [compare HubSpot partners by specialty](/blog/hubspot-partner-agencies-by-niche).
3. **Ask for a working session, not a deck.** Give each finalist the same real problem and see how they think.
4. **Check references at your stage.** Ask what went wrong and how the agency handled it.
5. **Start with a defined first phase.** Agree on deliverables, leading indicators and a review date before you commit long term.

## The Bottom Line

Choosing the right marketing agency when you are scaling to $100M is not about the lowest price or the most impressive logo wall. It is about finding a partner with the strategic depth, revenue fluency and operational capability to grow with you, and to hold their own in the boardroom.

## Frequently asked questions

- **When should a company scaling to $100M hire a marketing agency?** Hire when the plan needs skills or capacity your team cannot build fast enough, such as marketing operations, paid media at scale, or a website rebuild. If the gap is a single role you will need for years, a hire is usually the better fit. If the gap spans several disciplines, a partner that covers all of them is usually faster.
- **What should a marketing agency report on at this stage?** Pipeline contribution, cost per qualified opportunity, and marketing-sourced and influenced revenue, pulled from your CRM. Clicks, impressions and traffic belong in the report as diagnostics, not as the outcome.
- **How long should an agency trial or first phase last?** Long enough to see a full cycle of the work. For most B2B teams that means a defined first phase of roughly one quarter with agreed deliverables and leading indicators, then a review before committing to a longer term.
- **Should we hire one agency or several specialists?** Several specialists can work if you have an internal leader with the time to integrate them. If you do not, one partner that owns the full system, from tracking and CRM to campaigns and the website, removes the handoffs that usually break attribution.
