Financial, legal and technical diligence are standard in a SaaS acquisition. Marketing diligence is newer, and it's getting sharper. Acquirers who buy software companies for a living now run a dedicated marketing review, and saas.group describes theirs as a one-to-two-week exercise that ends in a written report for the deal team.
I led marketing or demand generation through three acquisitions: Lumerit by Pearson Education, Chargify by Battery Ventures, and Pingboard by Workleap. The pattern is consistent. The buyer isn't grading your creative. They're asking one question: is this growth real, repeatable, and transferable to us?
Here's what that question turns into, and what to have ready.
1. A pipeline definition that survives scrutiny
The first thing a diligence team does with marketing numbers is try to reconcile them. Marketing-sourced pipeline in the board deck, opportunities in the CRM, conversions in the ad platforms, sessions in analytics. If they don't tie, every number after that gets discounted.
Have ready:
- A written definition of qualified pipeline, agreed with sales, with the date it was adopted
- The CRM as the single system of record for pipeline and revenue
- Pipeline by source for at least eight quarters, with definition changes footnoted
If your definition changed last quarter to make the numbers look better, a buyer will find it. Say so first.
2. Channel concentration and founder dependence
Acquirers worry about growth that leaves with a person or a platform. If deals come mostly from the founder's network or personal brand, the buyer has to ask what happens after the founder steps back. The same logic applies to a single channel: if 70% of pipeline comes from one paid source or one partner, the buyer is pricing that risk. howtosaas lists demand generation, people and org structure, budget, the tech stack and integration as the core areas a marketing review covers; concentration risk cuts across all of them.
Have ready:
- Pipeline and closed-won by channel, trended
- What happens to each channel if its owner leaves
- Evidence that founder-led channels (the CEO's LinkedIn, the founder's network) are being turned into company channels
3. Fully loaded CAC and payback, by channel
A blended CAC hides everything a buyer wants to see. They'll rebuild it with headcount, tools, agencies and ad spend included, then split it by channel and segment.
Have ready:
- Fully loaded CAC: people, tools, agencies, media
- CAC payback in months, by channel and by segment where the data allows
- The two channels you'd cut first, and why you haven't
Knowing your weakest channel and having a plan for it reads as discipline. Discovering it in diligence reads as a surprise.
4. Funnel conversion by stage, with cohorts
Buyers want to know where the funnel leaks and whether it's getting better or worse. Stage-to-stage conversion rates, sales cycle length and win rates, trended over time and split by segment.
Have ready:
- Visitor → lead → meeting → opportunity → closed-won, by quarter
- Win rate and cycle length for your best-fit segment versus everyone else
- What changed when conversion moved, in writing
This is where a clear ICP pays off twice. If you can show that best-fit accounts close faster and retain better, you've shown the buyer where future growth comes from.
5. Organic and AI-search assets, and their risks
Search visibility is an asset a buyer inherits. It can also be a liability. saas.group describes the risk of a company with top organic positions that turns out to be part of a questionable link network that hasn't been penalized yet. That's a write-down waiting to happen.
AI search is the newer version of the same question. Is the company named when buyers ask ChatGPT, Perplexity or Google's AI answers for options in its category, and is that visibility built on durable sources or on luck?
Have ready:
- Organic traffic and pipeline from organic, trended
- A backlink profile you'd be comfortable showing a stranger
- A baseline of how often AI assistants recommend you for your core buyer questions
6. A brand and message the market actually holds
Buyers interview customers. If customers describe the product differently from the website, or can't say why they chose it over the alternative, the buyer sees a positioning problem they'll have to fund.
Have ready:
- Positioning that names the real alternative customers consider, the unique value, and the best-fit customer
- Customer quotes that say the same thing in their own words
- Win/loss notes that back it up
7. A marketing system that runs without heroes
The last question is transferability. Does marketing run on documented definitions, playbooks and a weekly rhythm, or on two people who know where everything is?
Have ready:
- Written playbooks for the channels that produce pipeline
- A weekly metrics review and a decisions log, so the buyer can see how calls get made
- Documented AI workflows and the standards they're checked against, if your team uses AI to produce work
This is the part most teams skip, and it's the easiest to fix ahead of time.
Start 12 months out, not 12 weeks
A diligence review takes weeks. Fixing what it finds takes quarters. The timeline that works:
| When | What to do |
|---|---|
| 12 months out | Agree the pipeline definition with sales. Make the CRM the source of truth. Start the decisions log. |
| 9 months out | Rebuild CAC and payback by channel, fully loaded. Address the channel you'd be embarrassed to explain. |
| 6 months out | Clean up search and backlink risks. Baseline AI-search visibility. Tighten positioning with customer evidence. |
| 3 months out | Document playbooks and workflows. Run a mock diligence review against this list. |
Frequently asked questions
Do acquirers really run a separate marketing diligence?
More and more do, especially buyers who acquire software companies repeatedly. saas.group describes a dedicated marketing review that takes one to two weeks and ends in a written report. Even when there isn't a separate review, the financial and commercial teams will test the same numbers.
What's the biggest red flag in marketing diligence?
Numbers that don't reconcile. If marketing-sourced pipeline in the board deck can't be traced to opportunities in the CRM, every other metric gets discounted. A written, agreed pipeline definition is the cheapest fix with the biggest payoff.
How far ahead should a SaaS company prepare its marketing for an exit?
Twelve months is comfortable. Six is workable. Fewer than three means you can document what exists, but you can't change the trend lines a buyer will read.
Can a fractional marketing leader help with exit readiness?
Yes, when they've been through it. The work is mostly definitions, reconciliation, channel economics and documentation, which a senior operator can drive part-time alongside your team. That's a large part of what a Fear Audit covers.
