SaaS Growth Consultant

Most SaaS growth advice is a list of channels. Growth is a system: who you sell to, how they find you, what happens between signup and revenue, and whether you can prove any of it. I build that system for B2B SaaS and devtools, measured on CAC, payback and net margin, not on MQLs.

SaaS growth consultant Ayoub Kaddouri: fractional head of growth for B2B SaaS and devtools
Diagnose, accelerate, scale. Fixed order, every time.
Short answer

A SaaS growth consultant designs and runs the acquisition and conversion system, usually as a fractional head of growth. What I own:

I am Ayoub Kaddouri, a full stack growth consultant. I work across SEO, technical marketing, paid ads, reporting and martech instead of one channel, which is why clients hire me when the problem sits between departments. Ten years running paid ads, eight on email, six on SEO and six on WhatsApp automation. For OneTake I engineered the marketing GTM engine and validated product-market fit in 72 hours through positioning, tracking and paid experiments. For Alphorm I built a €1M ARR revenue architecture. I have also run growth for B2B and industrial companies whose sales cycles run 90 days or more.

01 Growth is a system, not a channel

A SaaS at €500K to €5M ARR usually has the same four gaps. Someone runs ads. Someone writes content. Nobody owns the connection between a click and a renewal.

I have written the long version of several of these: how to reduce CAC, attribution tools compared, marketing automation for SaaS, Facebook Ads for SaaS.

02 Diagnose, accelerate, scale

  1. DiagnoseGrowth audit of the funnel, ad accounts, CRM, analytics and reporting. Every revenue leak mapped before any ad spend goes up. Output: a ranked roadmap.
  2. AccelerateTracking architecture, attribution model, automation that qualifies and nurtures 24/7, landing pages and messaging rebuilt around the ICP that actually renews.
  3. ScaleOnce CAC and payback are stable by channel, budget goes up and expands across Meta, Google, LinkedIn and YouTube. Weekly reporting from spend to ARR.
Fixed order

I do not turn ads up before the leaks are mapped and the measurement works. Scaling a broken funnel just makes the hole bigger faster.

06 Frequently asked questions

What does a SaaS growth consultant do?
A SaaS growth consultant designs and runs the system that turns spend into revenue: ICP and positioning, channel strategy, paid acquisition, attribution, marketing automation from signup to sale, and reporting on CAC, payback and margin. Often this is done as a fractional head of growth who owns the number for three to six months.
What is a fractional head of growth?
A senior growth operator who owns your growth budget, strategy and execution part time, typically 3 to 6 months, instead of a full-time hire. You get someone who has done it at several companies, with weekly reporting, at a fraction of a full-time senior salary. Useful between €500K and €10M ARR, before a full-time head of growth makes sense.
How is this different from a marketing agency?
An agency sells a channel: ads, SEO, content. I own the system across channels, including the CRM and the reporting, and I am measured on CAC and payback rather than on deliverables. I also hire and manage the agencies or freelancers when they are the right tool.
What is a good CAC payback for SaaS?
Under 12 months is healthy for most B2B SaaS. Best in class is 6 to 9 months. Above 18 months you have a cash flow problem regardless of LTV. The number should be calculated by channel, not blended, because blended payback hides the channel that is destroying margin.
Do you work with devtools and technical products?
Yes. Devtools and technical SaaS are a focus. The buyer is sceptical of marketing, PLG motion matters, and the growth system has to respect how developers actually discover tools. I have a full guide on <a href="devtools-marketing.html">devtools marketing</a>.
How quickly do you show results?
The audit takes one to two weeks and usually finds quick wins: killing an unprofitable channel, fixing a conversion step, correcting attribution. Measurement fixes show within a month. Structural changes to acquisition and automation take a quarter to show up in CAC and payback.
