Hiring a SaaS marketing agency, seen from the buyer's side
A SaaS marketing agency is an outside firm that runs some or all of your marketing on a monthly retainer. Their site
A SaaS marketing agency brings people who have grown software companies before, on a retainer with a term, an onboarding month and a reporting rhythm. Kamu brings a worker that starts today for a plan price and shows every action with its reason. Which is right depends on whether you are buying experience or hours.
Here is what you are agreeing to when you sign with a SaaS marketing agency, in the order it happens.
A discovery call, then a proposal. The proposal describes a retainer: a fixed monthly fee for a defined scope, usually with a minimum term and a notice period. The first month is onboarding. Kalungi, one of the agencies on the first page for this search, describes its first month as installing the foundation: ICP and messaging, positioning, a 30/60/90/180 plan, website and brand alignment, and a reporting baseline. After that you settle into a cadence, a weekly or fortnightly call and a monthly report, and Kalungi's own estimate of the client's time is two to five hours a week on reviews and syncs.
Agencies specialise. Some do paid media and nothing else; others do SEO and content, or brand and design; a few run the whole function. Kalungi's full-service tier is a useful reference for the top of the market: it says it replaces ten or more hires with one accountable team, puts the cost at $50,000 and up a month, and aims it at SaaS between $5M and $50M in revenue. Smaller agencies charge less, and almost nobody publishes a rate.
What you are buying is people who have done this before. An agency has run a launch, rebuilt a category page until it ranked, spent a real paid budget and learnt from it. That transfers, and it is the honest reason to pay a retainer.
Kamu is a different purchase. It is a plan from €25 to €349 a month with no term and no onboarding call. Give it a URL and it starts: cold email to people who match your buyer, articles for phrases with buyers behind them, posts from what shipped, a landing page, listings, a paused video ad. It has never done this before in any way that transfers, and it will not tell you your strategy is wrong. It will show you every action it took and why, the same morning.
Side by side
| Kamu | A SaaS marketing agency | |
|---|---|---|
| What you sign | A monthly plan, €25 to €349, cancel any month. | A retainer for a scope, usually with a minimum term and a notice period. |
| The first month | Kamu reads your site, writes a plan and starts the same day. | Onboarding. Kalungi describes its first month as ICP, messaging, positioning, a 30/60/90/180 plan and a reporting baseline. |
| Who does the work | One agent, every day, inside the plan's daily caps. There is no account manager. | A team at the seniority the retainer buys. At Kalungi, an Associate CMO backed by an execution team. |
| Your time | A short standup each morning and the approvals that spend money or change the plan, in chat, Slack, Telegram or WhatsApp. | Calls and reviews. Kalungi puts it at two to five hours a week for its full-service clients. |
| What it costs | €25 on Seed, €49 Starter, €149 Growth, €349 Scale, published. | Rarely published. Kalungi's full-service tier is $50,000 and up a month as of September 2026; smaller agencies charge less and quote per scope. |
| Experience | None that transfers. It reads your market fresh and learns from what your buyers reply. | The reason to pay: people who have launched, ranked and spent budget before, for companies like yours. |
| What you see | Every email, post, article, listing and ad, with the reason, as it happens. | A report on the cadence you agreed, written by the agency, plus whatever the calls surface. |
| Getting out | Cancel any month. Prospects, drafts, articles and the landing page stay in your account. | Notice, then a handover: ad accounts, analytics, content and the passwords to all of them. |
When A SaaS marketing agency is the better choice
Hire the agency when what you need is judgement earned elsewhere. A launch that has to land on a date, a paid budget in the tens of thousands, a category you are new to, a brand that needs to be designed rather than described: these are jobs where somebody who has done it three times before saves you the expensive version of learning. An agency also brings breadth Kamu cannot: design, PR, video shot with a camera, partnerships, events, and a senior person who will say your positioning is wrong. If you are past a few million in revenue and marketing is now a function rather than a task, an agency's structure fits, and the retainer is small against what a wrong quarter costs. And if you want a supplier who owns the outcome, with a contract and a person to ring when it is not working, that is what a retainer buys and what a plan price never will.
Questions
What does a SaaS marketing agency cost?
Few publish a price. The one figure on this page comes from Kalungi, which lists its full-service engagement at $50,000 and up a month for SaaS between $5M and $50M in revenue as of September 2026, and aims cheaper tiers at earlier companies. Smaller agencies charge less and quote per scope. Kamu is €25 to €349 a month, published, and the same for everyone.
How long does an agency take to show results?
Longer than the first invoice. Kalungi says its clients see clarity in month one, movement in month two and qualified opportunities by month three, and that is the honest shape of a retainer: onboarding, then work, then pipeline. Kamu starts the day you add a URL, which is not the same as saying it produces pipeline that day. The difference is that you can watch the work from the first morning.
Is Kamu a SaaS marketing agency?
No. An agency is a company of people you retain; Kamu is software that runs six growth jobs on its own and reports to you. It has no account manager and no creative team. It costs a plan price, starts the same day, and logs everything it does with the reason. If the word agency is doing the work of meaning somebody else handles marketing, Kamu qualifies. If it means experienced people, it does not.
When should a founder pick the agency over Kamu?
When the job needs experience you cannot get from a log. A launch on a date, a paid budget large enough that a wrong week hurts, a rebrand, a category you have never sold into. Also when you are big enough to get the senior people's attention, since the seniority you get tends to track the size of the retainer, and a small account at a large agency is a different product from the one that was pitched.
