What to know about raising customer acquisition financing

Customer acquisition financing is one of the fastest-growing forms of non-dilutive capital in the venture ecosystem. The industry's pioneer, General Catalyst, has deployed over $7B across 80+ companies, yet founders, operators, and investors alike still misread how it works. This is the primer: what it is, when it fits, what it costs, and how to run a process.

The Customer Value Fund is General Catalyst's customer-acquisition financing vehicle. Search interest has climbed roughly tenfold over five years.

01

Customer acquisition is an investment

For a company with product-market fit, customer acquisition is a measurable investment with a knowable return. You spend a dollar to acquire a customer, and you know what that customer is worth and when they pay you back.

Founders and investors increasingly accept that a fixed-return asset should be financed with non-dilutive capital, with equity reserved for speculative bets — R&D, new products, new markets. Acquisition spend with a known payback is the clearest fixed-return asset most growth companies have — and for a decade it was funded with equity anyway. The fix isn't more equity; it's financing predictable spend with capital that doesn't touch the cap table.

02

How it works

Capital goes into acquisition; repayment comes out of the revenue those specific customers generate, until the provider hits a capped return — after which the long-tail LTV reverts to you.

01Fund the spend

The provider funds a share of your sales & marketing spend — up to ~85%, depending on structure and cohort strength.

02Acquire the cohorts

That capital is deployed into customer acquisition, building defined cohorts with measurable payback.

03Repay from revenue

Capital is repaid out of the revenue those cohorts generate until the provider hits a capped return. The long tail reverts to you.

Repayment tracks cohort performance: a cohort that pays back slowly simply takes longer to repay. The market has largely converged on this cohort-linked structure for exactly that reason.

03

Customer acquisition financing vs. equity and venture debt

From equity, it's non-dilutive. You fund the same growth without selling ownership or transferring control. Equity stays reserved for the bets that genuinely need it.

From venture debt, it's built around the acquisition engine itself. Venture debt is sized off your last equity round and repaid on a fixed schedule, regardless of how the underlying spend performs. Customer acquisition financing is structured around customer-acquisition spend, with asset-liability matching on the back end — repayment tied directly to how the new cohorts perform.

For a high-growth business that's constantly scaling spend up and down with the attractiveness of its unit economics, that matching is the point. The capital flexes with the cohorts it funded, rather than a fixed schedule set at signing.

Venture debt vs. customer acquisition financing

Venture debt asks

“Who's backing you, and how much runway do you have?” It leans on your investors and balance sheet.

Acquisition financing asks

“What does a customer cost, and what are they worth?” With product-market fit, that has an answer.

04

When it's a fit

The threshold is roughly six-plus months of predictable, measurable unit economics. Once you can show that you reliably deliver a 6, 9, 12, or 18-month CAC payback, it's time to start considering non-dilutive capital to lean into that spend rather than funding it from the next round.

Before that, there's no cohort to underwrite and nothing to match repayment against. After it, every incremental dollar of equity spent on acquisition is dilution you didn't need to take.

You're ready when
Acquisition is discretionary and scalable — paid media, sales hires, partnerships, geo launches you can dial up or down.
Short sales cycles and CAC payback under 24 months.
You bill customers directly and can see revenue at the cohort level, so repayment can be matched to performance.
Positive, stable gross margins.
6+ months of cohort data, with a relatively tight distribution of outcomes (for example, paybacks trending within a 6–9 month band).
You can produce clean data on P&L, cohorts, margins, and spend by channel — the diligence pack a lender underwrites on.
12+ months of runway (if still free-cash-flow negative).
05

Who provides it

The market splits into two tiers. Upmarket generalists underwrite unit economics in any sector with measurable payback — larger facilities, typically $10M+ acquisition spend. The two upmarket generalists are General Catalyst's Customer Value Fund and Castle Roads. SMB sector specialists are platform lenders locked to one vertical's data model — faster and data-connected, but smaller checks and only within their lane.

General Catalyst proved the model at scale over five years, then moved upmarket as its fund grew. Today it concentrates on Series D through IPO; Castle Roads covers Series B through pre-IPO. Both are generalists. The sector specialists sit earlier still — Seed and Series A — each locked to a single vertical.

06

What it costs, and the terms that matter

There's no standard term sheet, but upmarket facilities share a common skeleton. Pricing scales with company stage and risk; everything below it is where the real negotiation happens. Normalize any offer to an all-in cost — and remember the benchmark: this should sit well below the cost of equity.

Pricing scales with stage
Seed / Series A
20%+

Earlier, thinner data, higher risk — the highest target returns.

Series B+
15–20%

Proven cohorts and scaling spend bring pricing down.

Pre-IPO
12–15%

Deep data and durable economics — closest to senior-debt pricing.

All figures are all-in effective APR.

Worth a close read

Lock-in is the term founders most often miss. If the only way out is the revenue share, you cannot refinance before the provider has recouped its return — which can take 18+ months. Negotiate prepayment ability up front.

Running a process — and the data lenders need

The diligence pack comes in two waves — enough to get indicative terms, then deeper data to confirm and close. Have the first wave ready before outreach: it shortens the process and signals you run the business on the same numbers the lender underwrites.

What the data room needs
Initial diligence

Enough to get to indicative terms.

  • Cohort file — LTV/CAC, payback, and retention by monthly cohort.
  • P&L and balance sheet — trailing 12–24 months.
  • Marketing spend by channel, with CAC by channel.
  • Operating model and projections.
  • Cap table and a summary of any existing debt.
Confirmatory

Verifies the cohorts and papers the deal.

  • Transaction-level data — anonymized, order- or customer-level.
  • Legal documents — charter, financing and security agreements, material contracts.
  • Verification of margins and unit economics against the cohort file.
  • Daily data feed, set up at close.
How the process runs

SMB platforms move fastest. They integrate directly into your stack — your Shopify store, ad accounts, billing — and can issue an offer and fund in as little as a few days. For $10M+ from an upmarket generalist, it's a structured raise that runs roughly like this:

Step 1 · Week 1
Initial data → indicative terms

Share the initial diligence pack. The provider returns indicative terms — size, advance rate, and a pricing range.

Step 2 · Weeks 2–3
Deeper data → term sheet

A second round of data, including transaction-level detail, supports a formal term sheet.

Step 3 · Close
Confirmatory diligence & closing

Confirmatory diligence and legal work, then standing up the daily transaction feed (Snowflake / BigQuery) that monitors the facility.
