They Test Everything.We Built a Machine for One Thing

KlientBoost works for 250+ clients across SaaS, ecommerce, and lead generation. Start with what that buys you, because it is real. A team that worked a SaaS trial funnel, a lead-gen form, and a Shopping feed in the same week sees patterns a single-lane shop never sees. A headline that lifts sign-ups often lifts add-to-carts too. If your business has more than one growth problem, one agency covering all three means fewer meetings, one bill, and one team holding the whole picture.

The cost of that range is simple arithmetic. Ecommerce is one expertise page on their site, next to the others. So the feed work, the Merchant Center work, and the product-level scaling work compete for attention with every other lane the company serves. We could not find how much of their 250+ client base is ecommerce, and they do not publish the split, so we are not going to guess at it. That number is the one that would actually settle this criterion, and neither of us can show it to you.

Our side is the opposite bet, and it has a cost too. Every hire, every tool, and every process here exists for Google Shopping and Performance Max on ecom stores. That is the only thing we do. So if your growth problem is a SaaS trial funnel or a lead form, our focus is worth nothing to you and we will say so on the first call. We turn work away for that reason regularly. Narrow only pays off when you happen to be standing in the narrow part.

For a store where Google Shopping decides the month, that is exactly where you are standing.

Focus is about the work. Fit is about you: your size, your stage, your budget. And this is the criterion where the wider agency has the better story.

KlientBoost serves three client types, which means they are shaped to take a much wider band of businesses than we are. Their pricing page offers three pricing options built around your goals and marketing channels. We read that page and their terms on 22 July 2026 and found no published minimum spend anywhere, so nothing on their site tells you that your budget is too small. That cuts both ways. It might mean they will work with a smaller account than we will. It might mean the real answer arrives on the sales call. Either way, if you are early and your spend is light, they are the more likely yes.

We publish our floor instead, and it rules people out. Around 5,000 euros a month in Google Ads spend is the practical bottom for us, and it is written on our own FAQ. Below that, Performance Max does not get enough conversion data to run properly and the management fee starts eating the media budget you actually need. So we say no and point people at the free community instead. That is a fit answer that costs us the sale, which is the only reason it is worth anything to you.

The honest read: their net is wider and ours is narrower on purpose. If you are under our floor, or your growth lives somewhere other than a product feed, the wider net is the right one. If you are a store past that floor with Shopping carrying the revenue, the narrow net was woven for you.

KlientBoost's pricing page publishes no numbers. It offers three pricing options for your goals and marketing channels, and the options arrive after you fill in a form. There is a fair case for that. Agency scope really does change the number, and a price on a page with no scope attached misleads somebody. Plenty of serious firms sell this way, and their form comes back with options and a marketing plan rather than a single take-it-or-leave-it figure.

It still costs you something, and the cost is time. You cannot rule them in or out on budget without a conversation. If you are shortlisting five agencies, that is five forms and five calls before you know whether any of them is even in your range. Estimates for their fees float around other blogs. KlientBoost has not published those numbers, so we will not repeat them here, and neither should anyone else.

Our whole rate card is on the site. Ten percent on your first 10,000 euros of monthly spend, dropping in brackets to six percent once you pass 150,000. You can work out what we cost tonight, with a calculator, without talking to us, and decide we are too expensive without either of us wasting an hour. The rate also falls as you scale, which is the part we would rather you check for yourself than take our word for.

One more thing worth saying, because it argues against us. A published percentage is only simple while the scope stays simple. Ours covers Google Ads management and nothing else, so it fits on a page. An agency selling paid media plus conversion testing plus landing pages genuinely has a harder number to write down, and their form is a reasonable answer to a real problem.

It still leaves the criterion where it is. One side publishes the number. The other publishes a form.

Terms are the part nobody reads in month one and everybody reads in month five. They decide what happens on the bad month, not the good one.

Here is exactly what we found on their side, and exactly what we did not. On 22 July 2026 we read KlientBoost's pricing page and their terms looking for contract length, notice period, commitment, or cancellation wording. We found none of it. That is not evidence of a long lock-in, and we are not going to imply it is. Lots of good agencies work month to month and simply never write it on a page. What it does mean is that you cannot know your exit before you are on a call with them, and this is the one criterion where not knowing is itself the finding.

Ours is published because it is the strongest thing we can say about how we sell. Month to month, no lock-in, cancel any time. No setup fee. That is not generosity, it is pressure we put on ourselves: if the account stops working, you can leave at the end of the month, so we have to keep earning it every month. An agency that can only keep you through a contract will eventually behave like one.

One fair caveat on our side. Month to month cuts both ways for you as well. Google Ads accounts, especially Performance Max, need a run of weeks before the data means anything, so leaving after three weeks usually tells you nothing except that three weeks is not long enough. Short terms are a safety net, not a testing plan.

This one goes to them, clearly, and it is the most impressive thing about the company.

KlientBoost's Clutch profile shows 4.9 from more than 400 verified reviews. Almost no agency at any size sustains that volume of public, verified feedback over years. Ours is Trustpilot 4.8 from 38 reviews. Theirs is more than ten times the volume, and volume is not nothing: a rating built on 400 opinions is far harder to fake, far harder to cherry-pick, and far more likely to have caught the company on a bad month. On top of that their results page claims more published case studies than any other marketing team on the planet. Make of the superlative what you like, but the library is real and you can browse it.

The one thing we can tell you about the shape of their proof is what we could not read. Clutch blocks automated checks, so we could not read the review texts ourselves, which means we cannot tell you how many of those 400+ come from ecommerce clients rather than SaaS or lead gen. We also saw a search snapshot showing a 4.8 rating across 381 G2 reviews, but the page itself blocked our check, so we left it off this page rather than cite something we could not open.

Our proof is shaped differently, not better. Fewer reviews, all from ecom stores, plus named clients on camera telling their own story, plus press coverage you can click through to. Different question, different answer: total volume across three industries, or a smaller set entirely inside yours. Both are real. Only one of them is bigger.

Most agencies claim technology and mean a reporting dashboard. KlientBoost is not one of those. They built and publish Kite, a marketing analytics tool that turns marketing data into budget recommendations. We checked that page on 22 July 2026. Shipping any real software is more than the vast majority of agencies ever do, and a tool that tells you where the next budget euro should go is genuinely useful.

The distinction worth understanding is the job the software does. Kite, as their own page describes it, reads marketing data and recommends budget. It sits above the account looking down. Our eight systems sit inside the account doing the work: Feed Intelligence engineers the product data going in, Anomaly and Self-Heal watch what comes out every hour on every account, the Labelizer ranks every product every night to decide which one deserves the next euro. Analytics that recommends a budget and software that rebuilds a feed at three in the morning are different jobs, and only one of them changes what Google sees.

The limit on this comparison is worth stating plainly. We only know what a company puts on its own site. KlientBoost may well run internal tools they have never published, and if they do, this row is unfair to them and we would want to know about it. We checked their pages on 22 July 2026 and none of them advertises software that runs the ads account itself. That is the honest boundary here: we are comparing what is public, because what is public is all a buyer can weigh up before signing anything. Ask them on the call what runs overnight, and ask us the same.

KlientBoost is visibly a real company. Founder Johnathan Dane, 40+ named team profiles, offices in California, North Carolina, and London. Nothing hidden about who they are or who does the work, and that matters more than it sounds. A bench that size covers holidays, sick weeks, and a resignation without your account going quiet, and three offices across two continents means somebody is awake for most of your day. Small teams do not have that. Ours does not.

Our answer is the other one. Nineteen people, all named with their roles on our about page, and the team lead on your account has scaled their own ecom brands. Fewer people means fewer hops between you and the person who can actually change a bid, and it means the person who answers your message is usually the person who made the change. It also means we feel it when someone is on holiday, which is exactly why we built software to watch the accounts instead of hiring a night shift.

Here is the part neither of us can prove to you, and you should be suspicious of any agency that claims otherwise. Nobody publishes who gets assigned to your specific account before you sign. Not them, not us. A team page tells you who exists at the company, not who will be reading your search terms on a Tuesday morning, and not how fast that person answers when something breaks on a Saturday.

So ask both of us the same three questions on the call. Who owns my account. What have they scaled that looks like my store. How fast do they answer, and on which channel. Write the answers down. The agency that gives you a name instead of a job title is the one telling you the truth about People, whichever of us that turns out to be.
