PILLAR ESSAY · DILIGENCE
The partner you have been talking to wants one more thing before the term sheet. How will you deploy the round.
Most founders answer with a 25-page marketing deck and vague intent. A few founders answer with a three-page allocation plan. The few raise faster and at better terms.
Here is what the three-page plan contains, page by page, with the math investors actually read.
The Paid Media Plan That Holds Up in Diligence
By Eleni Buras | Published 2026-05-15 | Updated 2026-05-16
TL;DR
- A diligence-grade paid plan is three to five pages, not a deck. It reads like a CFO wrote it.
- Three load-bearing components: channel mix tied to sales motion, payback math by channel, decision rules for scale and pause.
- The most common red flag is an aspirational CAC or ROAS number with no methodology behind it. Investors read it as a guess.
- This is a pre-funding tool, not just a post-funding tool. A diligence-grade plan in the data room raises rounds faster.
- The plan that ships on Monday is more valuable than the plan that wins a board debate. Specific channels, specific dollars, specific hurdles.
The data room is open. Your deck is polished. Your metrics are clean. The partner you have been talking to wants one more thing before they take it to the rest of the committee.
How will you deploy the round.
This is the question that splits Series A and Series B raises into the ones that close fast and the ones that grind for another six weeks. Most founders are unprepared for it. They have a financial model that shows aggregate marketing spend by quarter, a pitch-deck slide that lists three to five channels, and a vague intention to “test and learn.” That answer is not diligence-grade. It is a marketing intention masquerading as a capital plan.
I have audited paid programs at companies raising Series A, Series B, and growth rounds. The ones that close clean show up to diligence with a three-page allocation plan that the CFO has signed off on. The ones that grind show up with a 25-page marketing deck that takes the partner a week to extract a decision from.
This is the long-form answer to a question I get on almost every discovery call: what does a paid plan look like when it is actually built for an investor.
What investors actually read
Before the framework, the demand side.
The investor reading your paid plan is not a marketer. They are usually a partner with a finance or operating background who has reviewed 50 to 200 GTM plans in the last five years. They are skimming for three signals.
Signal one: does the founder know the sales motion? The channel mix is downstream of the motion. If the plan opens with channels before establishing how the company sells, the partner concludes the founder has not done the work.
Signal two: is there a math layer? Investors want to see CAC payback by channel, hurdle rates, and a path to the company’s stated capital efficiency targets. Plans without explicit payback math get filed under “marketing aspiration.”
Signal three: are there decision rules? A plan that says “we will optimize and scale what works” is not a plan. A plan that says “channels scale at sub-18-month payback, pause at over-24-month payback, and test new channels every 90 days at a 10 percent budget reserve” is a plan.
According to recurring patterns in First Round Review post-mortems on Series B failures, the marketing-plan-as-aspiration is one of the most common artifacts founders bring to a raise that does not close. Partners are not skimming for inspiration. They are skimming for evidence the founder will deploy capital with discipline.
The capital deployment framing
The framing shift that separates a marketing plan from a diligence-grade plan is the one from spend to deployment.
A marketing plan answers “what will we do.” A capital deployment plan answers “what return will we generate, over what payback window, at what risk.”
The capital framing forces three things into the document that a marketing framing usually leaves out.
Hurdle rates. Every channel has a minimum payback window it must hit to receive ongoing investment. The hurdle is stated up front. Channels are graded against it, not against vague optimization narratives.
Decision points. The plan specifies the moments where the founder will make a scale, pause, or reallocate decision. These are dates and criteria, not vibes. “End of week 4: scale Channel A if CAC payback projection is under 18 months. Pause Channel B if pipeline contribution is below 15 percent of total paid pipeline.”
Sensitivity analysis. The plan shows what happens if the assumptions are wrong. If CAC comes in 30 percent higher than projected, what is the new payback. If the close rate is 20 percent lower than projected, how does the channel mix change. Investors love sensitivity work because it reveals whether the founder has actually pressure-tested their own plan.
Founders who internalize this framing stop thinking like marketers and start thinking like the CFO who has to defend this line at the next board meeting. That is the shift the partner is looking for.
Defined terms
Use these in the document. Define them on first reference if your investor is not technical.
CAC payback. Months of gross-margin-adjusted revenue required to recover the customer acquisition cost. CAC divided by (ARPA times gross margin). Series A B2B SaaS target: under 14 months.
Channel-CAC. Spend on a specific channel divided by attributable new customers. Distinct from blended CAC. Channel-CAC is the strategic number for allocation decisions.
Blended CAC. Total S and M spend divided by total new customers. The number the board cares about. Pair with channel-CAC always.
Pipeline coverage. Total pipeline divided by quarterly bookings target. Standard board metric for sales-led companies. Healthy Series A B2B SaaS sales-led: 3x to 4x.
Hurdle rate. Minimum payback window a channel must hit to keep receiving spend. Set above the company’s blended payback target so that any channel above hurdle is contributing favorably to the average.
Attribution methodology. The named approach to crediting conversions to channels. UTM-based first-touch, multi-touch with platform weights, lift-test-based, or a hybrid. State it explicitly. Investors who have seen attribution disagreements blow up board meetings will appreciate the clarity.
Capital efficiency ratio. Net new ARR (or contribution-margin GMV for DTC) divided by net spend over the same period. Target ratios at Series A: 0.6 to 1.0. Series B: 1.0 to 1.5.
Diligence-grade. Specifically: a document the partner can take to the investment committee without rewriting. The bar is not “thorough.” The bar is “decision-ready.”
The 5-part diligence-grade plan
The plan structure. Three pages minimum, five pages maximum. The longer it gets, the less diligence-grade it is.
Part 1: Sales motion summary (one paragraph)
Open the document with a paragraph that explains how the company sells. ACV, sales cycle length, primary acquisition surfaces, key decision-makers in the buying process. This anchors everything that follows.
Example, for a Series A B2B SaaS:
“We sell a workflow product to revenue operations leaders at $50M to $500M revenue companies. ACV is $35K with a $5K expansion in year two. Sales cycle is 45 to 75 days from first touch to signed contract. Buyers are RevOps managers (champion) and VP RevOps or CRO (economic). 60 percent of pipeline comes from inbound research; 40 percent from outbound supplemented by retargeting.”
This single paragraph tells the partner the entire shape of the business in 60 seconds. The paid plan that follows has context.
Part 2: Channel mix and rationale (one page)
The channel mix table. Each channel: percentage of paid budget, dollar amount monthly at run rate, the role it plays (acquisition, retargeting, ABM-light, brand), and the hurdle rate.
Below the table, three short paragraphs of rationale. Why these channels, not others. What the sales motion implies. What the prior testing showed (if any).
Avoid:
- Listing every channel “we plan to test.” Limit to two channels for phase one, plus retargeting.
- Generic statements like “LinkedIn is essential for B2B.” Specific reasoning only.
- Aspirational CAC numbers without methodology. State the projected channel-CAC range and where the range comes from (prior testing, benchmarked comparable, or assumption stated explicitly).
Part 3: 90-day ramp (one page)
The phased spend by week. Three phases.
Phase 1 (weeks 1 to 4): Diagnostic. Flat daily spend across two channels. Total spend, KPIs reviewed end of week 4. No scaling changes.
Phase 2 (weeks 5 to 8): Validation. Winning channel scaled. Losing channel paused or held. One new test if validated channel is carrying.
Phase 3 (weeks 9 to 12): Scale. Graduated scale on validated channel. Retargeting layer active. End-of-quarter review against payback hurdles.
Add a Gantt-style visual showing spend by week. Investors read visuals faster than tables.
State the weekly KPIs explicitly: spend by channel, conversions by channel, channel-CAC running 4-week average, pipeline added by channel. The weekly KPI list is what tells the partner you have a measurement layer built.
Part 4: Payback projection (one page)
The math layer. Three views.
Channel-CAC payback projection. Per channel, projected CAC payback by month 6, with the assumptions stated (close rate, average deal size, gross margin).
Blended CAC trajectory. Month-by-month projected blended CAC over the first 6 months. Show the trajectory from diagnostic spend (high blended CAC, low volume) to validated scale (lower blended CAC, higher volume).
Sensitivity analysis. Two scenarios. What happens if CAC comes in 30 percent over plan. What happens if close rate is 20 percent under plan. State the implications for spend, ramp, and pause decisions.
The sensitivity work is the highest-leverage page in the document. Most plans do not include it. Including it puts the founder in the top 10 percent of plans the partner has read this year.
Part 5: Decision rules (half page)
The explicit rules for scaling, pausing, and reallocating.
- “Channel A scales 2x if channel-CAC payback projection is under 18 months at end of week 4.”
- “Channel B pauses if pipeline contribution is below 15 percent of total paid pipeline at end of week 6.”
- “10 percent of budget held in reserve for a new-channel test at month 4 if validated channel is fully scaled.”
- “Quarterly review at month 3 and month 6 with channel-CAC payback as the primary lens.”
Decision rules state the founder will make calls, not optimize indefinitely. This is the trust signal the partner is reading for.
Three to five pages. Decision-ready. Built once, used twice.
The five-part plan above is what a partner can take to committee without rewriting. You can build it yourself. The hardest part is the math: channel-CAC payback projections, sensitivity analysis on the assumptions, and committed decision rules in writing.
The 10-Day Allocation Audit produces the diligence-grade document. The same three to five pages you would put in the data room. $4K fixed fee. Strategy only. We do not run your ads. One in five audits ends with a wait recommendation, which in a diligence context is worth knowing before the partner finds it.
Comparison: marketing plan vs diligence-grade plan
| Typical Marketing Plan | Diligence-Grade Plan | |
|---|---|---|
| Length | 15 to 30 pages | 3 to 5 pages |
| Format | Slide deck | Document or one-pager |
| Opening | Market opportunity, ICP narrative | Sales motion in one paragraph |
| Channel section | List of channels with “test and learn” language | Two to three named channels with dollar splits and hurdles |
| Math | Annual budget by category, aggregate ROAS target | Channel-CAC payback by month, blended trajectory, sensitivity |
| Decision logic | Implicit (we will optimize what works) | Explicit (scale at sub-18-month payback, pause at over-24) |
| Attribution | Often unstated | Methodology named in one paragraph |
| Reads like | Marketing team output | CFO output |
| Partner reaction | ”Let me follow up with the team" | "This is decision-ready” |
| Time to investment committee | 1 to 3 weeks | Days |
The format itself is part of the signal. A three-page document signals decisiveness. A 30-page deck signals defensiveness.
Vertical-specific notes
B2B SaaS
The math layer is the highest-leverage section. Channel-CAC payback by source is the number partners look at first. State the methodology behind the channel attribution explicitly.
Audit pattern. $3M ARR Series A B2B SaaS preparing Series B raise: rebuilt the marketing plan from a 22-page deck to a 4-page allocation document. Closed Series B 18 percent faster than the prior round, partner cited the paid plan as a “differentiator in committee” during the term-sheet call.
B2C SaaS
The optimization-event decision (paid-subscriber event vs install) belongs in the channel mix rationale. Most investors who have seen B2C SaaS pitches in the last three years know the optimization-event trap. Stating that you are optimizing for paid trial start, not install, is a credibility signal.
Audit pattern. $2M ARR seed-stage consumer subscription raising Series A: opened the diligence document with a sentence on optimization event (“we optimize for 7-day paid trial start, not install, which moved free-to-paid from 4 percent to 11 percent in 90 days”). The single line was cited by two of the three Series A investors as decisive.
E-commerce / DTC
Contribution-margin ROAS is the number, not topline ROAS. State the methodology for getting from topline ROAS to contribution-margin ROAS (deduct COGS, fulfillment, returns, platform fees). The 30 to 45 percent gap between topline and contribution ROAS is the source of most DTC pitches that lose committee confidence.
Audit pattern. $8M GMV post-seed DTC raising Series A: replaced the topline ROAS slide with a contribution-margin walk showing the gap and the 12-week recovery trajectory (1.6x to 3.4x ROAS at flat spend). Closed the round.
The pre-funding application
A diligence-grade paid plan is not just a post-funding tool. It is one of the strongest pre-funding signals a founder can send.
When a Series A or Series B partner is evaluating a deal, the standard question is whether the founder can deploy the round. Most founders answer with conviction and vague intent. A few founders answer with a three-page allocation plan in the data room. The plan does three things at once.
It demonstrates operational maturity. The partner concludes the founder has run the math, not just the narrative.
It de-risks the deployment question. The partner does not have to imagine how the round will be deployed. They can see it.
It shifts the negotiation. Founders who walk in with a diligence-grade plan tend to raise faster and at slightly better terms. The plan does not change the company’s fundamentals. It changes the partner’s confidence in the founder’s ability to convert capital into outcomes.
I have seen this pattern repeat across founders I have worked with pre-funding. The plan in the data room is one of the highest-leverage artifacts a founder can produce in the weeks before a raise.
The most common diligence red flags
A short list, in order of frequency.
Aspirational CAC numbers with no methodology. “We will hit $400 CAC at scale” reads as a guess if the methodology is missing. Always state the assumption stack.
Equal-thirds channel splits. Splitting evenly across three or four channels is the answer to no specific question. It signals the founder defaulted rather than decided.
No attribution methodology stated. Partners who have lived through attribution disagreements at scale will flag this immediately.
Annual budget aggregates without monthly ramp. Investors want to see the deployment curve, not the total. A $2M annual paid budget could be deployed in 12 ways. The plan should specify which.
Brand line items above 15 percent. Brand spending at Series A is mostly defensive. Allocating more than 15 percent of paid budget to brand at this stage usually signals the founder has not yet found a performance channel that scales.
No mention of pause or reallocation criteria. A plan that only describes scaling implies the founder will not pause underperforming channels. Partners read this as undisciplined.
When to build the plan with help
You can build a diligence-grade paid plan yourself. The five-part structure is not secret. The hard part is the math and the discipline to commit decision rules in writing.
Founders bring me in for one of three reasons in this context. They are preparing for a raise and want the document in the data room. They have a board meeting where the paid plan is the primary topic. Or an investor in diligence asked for a paid allocation review as a condition of moving to term sheet.
The 10-Day Allocation Audit produces the document. Three to five pages, diligence-grade, with the channel mix, the 90-day ramp, the payback projection, the sensitivity analysis, and the decision rules. $4K fixed fee. Strategy only. We do not run your ads.
If the underlying allocation logic is not yet ready, the audit will tell you that. One in five engagements ends with a wait recommendation. In a diligence context, that signal is worth knowing before the partner finds it.
Frequently Asked Questions
What do investors actually look at in a marketing plan?
Three things. The channel mix and its tie to the sales motion (does this make sense for how they sell). The payback math (CAC payback by channel, blended CAC trajectory, hurdle rate). The decision rules (when does the founder scale, when does the founder pause). Investors do not look at impression projections, CPM benchmarks, or aspirational ROAS. The ones who do are not the ones writing your next check.
What is the difference between a marketing plan and a diligence-grade plan?
A marketing plan is a roadmap of activities. A diligence-grade plan is a capital deployment document. It states the dollar split, the payback hurdle, the measurement layer, and the decision points. It reads like a CFO wrote it, not a marketer. Diligence-grade plans are typically three to five pages. Marketing plans are typically 15 to 30 pages of slides and rarely survive their first contact with a partner who has seen 50 of them.
How long should a diligence-grade paid plan be?
Three to five pages. Page one: channel mix and rationale. Page two: 90-day ramp with weekly KPIs and decision points. Page three: CAC payback target by channel and blended projection. Pages four and five if needed: vertical-specific notes, attribution methodology, sensitivity analysis on the payback math. Anything longer signals to investors that the founder is hiding decisions inside narrative.
Should the plan include specific channels or stay strategic?
Specific channels with dollar amounts. Vague strategic language is the single most common reason a paid plan does not survive diligence. Investors want to see that the founder can make the channel decision, not delegate it. The plan names the two to three channels for the first 90 days, the percentage split, the monthly dollar amount, and the hurdle each channel must hit to graduate to scale.
What is the most common diligence red flag in a paid plan?
An aspirational ROAS or CAC number with no methodology behind it. If the plan says “we will hit 3x ROAS” or “we will reduce CAC to $400” without explaining the channel-by-channel math, the investor reads it as a guess. The fix is to anchor projections to either historical channel data (if you have it) or to benchmarked ranges from comparable companies, with the assumptions stated explicitly.
How do I write the paid plan section of a board update?
Three short paragraphs and a table. Paragraph one: spend deployed this period by channel, against plan. Paragraph two: CAC payback and pipeline coverage trend versus hurdle. Paragraph three: the one decision being made this quarter (scale a channel, pause one, test a new one). Table: spend, conversions, channel-CAC, payback by channel. Skip the campaign-level narrative. Investors do not need to hear about creative refreshes.
Does this matter pre-funding or only post-funding?
Pre-funding more than post-funding. A diligence-grade paid plan is one of the strongest signals a founder can send during a Series A or Series B raise. It tells the partner the round will be deployed against a framework rather than absorbed into a generic growth budget. Founders who include a three-page allocation plan in the data room raise faster and at better terms than founders who include marketing slides.
One artifact. Two audiences. Both decisive.
The same diligence-grade plan goes in the data room before the raise, and into the board pack after the close. Channel mix on page one. 90-day ramp on page two. Payback projection on page three. Sensitivity and decision rules on pages four and five.
