A straight comparison of a SaaS marketing agency vs building an in-house team. Both can work. The right call depends on your stage, your budget and how fast you need breadth across channels. Here is the honest version, including when in-house actually beats us.
| Dimension | TG3 (specialist agency) | In-house |
|---|---|---|
| Time to full breadth | Immediate, seven channels live | 6 to 18 months of hiring |
| Cost shape | Flexible retainer, scales with need | Fixed salaries plus benefits and ramp |
| Channel depth | Seven specialist heads | Limited by who you can hire and afford |
| Stage experience | 47 SaaS engagements of pattern | Usually one prior playbook per hire |
| Product immersion | Close, not embedded | Deep, lives it daily |
| Best when | You need breadth and speed now | You are at scale and want to own it |
Seven specialist channels live immediately, versus hiring seven specialists over many months.
Scale up for a launch, down between them. An in-house team is fixed cost whether you need it that month or not.
We have run 47 SaaS engagements. A new in-house hire brings one prior playbook, often from a different stage.
We are not going to pretend the agency always wins. A good comparison admits where the other side is stronger and an in-house team has real advantages an honest agency will name. Here is where building in-house is genuinely the better call, no spin.
An in-house team lives the product every day. For a deeply technical or fast-changing product, that immersion is hard to match.
In-house is in every standup. An agency is close but not embedded the same way.
Past a certain size, owning the function outright can cost less than retaining an agency for the same scope.
The sticker price of an in-house team looks clean: a few salaries on a spreadsheet. The real cost is messier. Each senior marketing hire runs well over six figures loaded once you add benefits, tooling, recruiting fees and the three to six months of ramp before they produce anything. Multiply that across the seven specialisms a modern SaaS motion needs and you are past a million dollars a year before a single campaign ships.
Then there is the timing problem. You cannot hire all seven specialists at once, so you sequence them, which means you are running a partial motion for a year while the team fills in. The channels you have not hired for yet simply do not happen. A SaaS marketing agency closes that gap on day one, because the bench already exists and it is already senior.
None of this means in-house is wrong. It means the comparison is not agency cost versus salary cost, it is agency cost versus the fully loaded cost of building, ramping and retaining a team while running a partial motion in the meantime. Once you are large enough to keep a full senior team busy every month, that math flips toward in-house. Below that line, the agency usually wins on both speed and total cost.
For most SaaS between $1M and $20M ARR, an agency wins on breadth and speed because you get seven specialist channels immediately instead of spending a year hiring them. Once you are large enough that a full in-house team is cheaper than the agency scope and you can attract senior specialists, owning it outright starts to win. The honest answer is that the best path is often both in sequence: agency to find what works and move fast, in-house to own the proven motion later. Whichever you pick, decide it on your real stage and budget rather than a blanket rule, because the right call genuinely flips as you scale and the wrong one costs you either a year of speed or a pile of fixed cost you did not need yet. There is no universally right answer here, only the right answer for your stage.
Neither is universally better, it depends on stage and scope. A SaaS marketing agency wins on breadth and speed, giving you seven specialist channels immediately instead of a year of hiring, with flexible cost that scales up and down. An in-house team wins on deep product immersion and, at large enough scale, on long-term cost. Most scaling SaaS use an agency to find the repeatable motion fast, then build in-house against what works.
When you are at enough scale that a full in-house team costs less than the equivalent agency scope, when your product is so technical or fast-changing that daily immersion is essential and when you can actually attract senior specialists across every channel. At that point owning the function outright gives you control and embedded availability an agency cannot fully match. Below that scale, the hiring time and fixed cost usually favour an agency.
Yes and it is common. Many of our engagements are hybrid: the in-house team owns the channels they are strong at, we cover the rest and flex for launches and reporting rolls up consistently so leadership sees one picture. The agency also de-risks future hires, because you build in-house against the channels you have proven rather than guessing which playbook will work.
Our retainer starts at $7,500 a month, well below the loaded cost of even one senior marketing hire once you count salary, benefits and ramp time. A full in-house bench across seven channels runs over a million dollars a year. The agency math favours you until you are large enough to keep a full team fully utilised, at which point the comparison shifts toward in-house.
An agency is producing inside the first two weeks because the senior bench already exists. Hiring even one specialist takes a quarter to recruit, onboard and ramp and building a full team takes six to eighteen months. For a SaaS that needs breadth and momentum now, the speed difference is the single biggest factor in the comparison.
Yes. We run SaaS marketing across all seven countries we serve: United States, United Kingdom, Canada, Australia, Singapore, India and Germany. The agency-versus-in-house math shifts a little by local salary costs but the breadth-and-speed advantage holds everywhere. Use the region selector to switch.
For most scaling SaaS the fastest path is both in sequence. Start with a SaaS marketing agency to get seven channels live immediately and find the repeatable motion, because hiring a full team takes six to eighteen months you usually cannot spare. Then build in-house against the channels you have proven, hiring into known winners rather than guessing. The agency de-risks the expensive hires and hands over a working system, so the in-house team starts from a running engine instead of a blank page.
