What actually changes

Four shifts that break what used to work

Before

Growth came from a few channels that worked

Now

Those channels saturate, and CAC climbs as you push past their efficient ceiling

Early growth usually comes from one or two channels with more headroom than budget. Somewhere past Series A the reverse becomes true: you have more budget than headroom. Spend keeps rising, volume keeps rising, and blended CAC quietly rises with them — because the marginal customer is more expensive than the average one, and blended reporting hides that.

Before

Founders and a few reps closed everything

Now

A real sales team needs a motion that works without the founder in the room

Founder-led selling doesn't document itself. When headcount grows, the parts that made deals close — qualification instinct, the objection handled in the third call — exist only in one person's head. Win rates drop, not because the new reps are worse, but because nobody wrote down what they were supposed to be doing.

Before

Attribution was roughly right with two channels

Now

With six channels and a longer cycle, the platforms collectively claim more revenue than you booked

Each ad platform reports conversions it believes it influenced, using its own attribution window. Add channels and the overlap compounds, so the sum of platform-reported revenue exceeds actual revenue. Meanwhile browser restrictions have removed a chunk of the client-side signal entirely. You are now optimising bids against numbers that do not reconcile to the bank.

Before

The board asked whether you were growing

Now

The board asks whether the growth is efficient enough to fund the next round

Series B diligence looks at the quality of growth, not just the rate: CAC payback, net revenue retention, cohort curves, magic number. Growth purchased inefficiently survives a growth-rate question and fails a cohort audit. The metrics have to hold up when someone segments them.

Five questions

Diagnose it yourself first

You do not need us to answer these. If you can answer all five confidently, your growth engine is in better shape than most at this stage and you probably do not need an outside team. If two or more make you hesitate, that hesitation is the constraint.

1. 01

   Does your blended CAC include agency fees, tooling and salaries?

   Ad platforms report cost per acquisition excluding everything that is not media. Fully loaded CAC is frequently 20–40% higher than the dashboard number, and it is the one the board will use.

2. 02

   Can you state CAC payback in months, by channel, from memory?

   Payback is the cash-flow constraint on scaling. If it is longer than the runway you are willing to commit, a healthy LTV:CAC ratio still will not let you spend faster.

3. 03

   Does the sum of platform-reported revenue exceed your booked revenue?

   If it does — and past four channels it usually does — you are allocating budget using numbers that double-count. The gap is the size of your attribution problem.

4. 04

   Do your retention cohorts flatten, or keep declining?

   A flattening curve means a durable base you can build on. A curve still falling at month 12 means you are refilling a leaking bucket, and every efficiency gain upstream gets consumed downstream.

5. 05

   Could a new rep close a deal using only written material?

   If the answer is no, your sales motion is not yet an asset — it is a set of individual skills, and it will not survive the hiring plan attached to your next round.

Published work

Engagements at this stage

Every figure below comes from the linked case study. We do not publish aggregate outcome claims we cannot attribute to a specific engagement.

When not to hire us

This is the wrong engagement if…

• Retention is the real problem. If cohorts are still falling at month 12, acquisition efficiency is not your constraint. Fixing the funnel upstream will move money through a bucket that still leaks.
• Product-market fit is unsettled. If you cannot name who the product is for and why they choose it, the growth system has nothing stable to optimise against. We will tell you this rather than take the work.
• You want someone to run ads. Media buying alone is a cheaper service than this one, and several firms do it well.

Commercials

What this costs

Priced on scope, never as a percentage of ad spend — that model pays an agency more when your budget grows, whether or not the growth was profitable.
