In-House or Agency? The SaaS Growth Decision Most Founders Get Backwards
Every software company reaches the same fork in the road. Organic search is starting to matter, nobody internally has the time to own it properly, and the board wants a plan by the end of the quarter.
The debate that follows is almost always framed as a budget question. Do we hire someone, or do we pay an agency?
That framing is the problem. The real question is not who does the work. It is which parts of the work you actually need, and whether you have any way of judging whether they are being done well.
Key Takeaways
- In-house versus agency is the wrong opening question. Start by defining what needs to be true in twelve months, then work backwards to the resourcing.
- A single in-house hire is rarely a full SEO function. Most SaaS growth needs content, technical work and authority building, and very few people are strong at all three.
- Agencies vary enormously by speciality. A team that excels at content scale may be weak at technical fixes, and the marketing rarely tells you which is which.
- Most companies past Series A end up somewhere in the middle, with an internal owner and specialist support around them.
- If you cannot articulate what success looks like in numbers, you are not ready to hire either way.
Start With the Twelve-Month Picture
Before anyone talks about headcount or retainers, get specific about the outcome. More traffic is not an outcome. More qualified demos from people who found you through search is an outcome.
The reason this matters is that the answer changes the entire shape of the resourcing decision. A company that needs 200 well-researched articles has a completely different problem from one whose site takes six seconds to load.
Write down the three things that need to be true in a year. Almost everything else follows from that list.
What Building In-House Actually Buys You
The strongest argument for hiring is product knowledge. An internal person sits in on sales calls, hears the objections and knows why customers churn. That context is genuinely hard to transfer to an outside team.
Continuity is the second argument. Institutional memory stays with you when a contract ends, and the work compounds rather than resetting.
The catch is scope. SaaS search performance usually needs strong writing, technical SEO and authority building at the same time, and a single hire will be excellent at one of those and adequate at best in the others.
There is also a hidden cost most plans miss. A junior hire needs someone senior to direct them, and if nobody in the business has done this before, you have bought execution without strategy.
What Outside Help Actually Buys You
Agencies sell speed and pattern recognition. A team that has run the same play across thirty software companies will spot in a fortnight what an internal hire might take two quarters to work out.
The difficulty is that agencies are far less interchangeable than their websites suggest. One might be genuinely excellent at building content at volume while being weak on technical fixes, and another might be the reverse.
A more useful way to shortlist is by speciality rather than by ranking. MADX Digital take that approach in their comparison of the SaaS SEO market, grouping firms by what they are genuinely strongest at instead of ordering them one to ten.
That framing is worth borrowing even if you never contact anyone on the list. Working out whether your bottleneck is content, technical performance, or authority tells you which kind of partner to look for, and it saves you sitting through four pitches that were never relevant.
The Hybrid Model Most Teams Land On
In practice, few companies past their first funding round choose one route cleanly. The arrangement that tends to survive contact with reality is an internal owner plus specialist support.
The internal person holds the strategy, owns the relationship with product and sales and decides what gets prioritised. They are the one accountable when the numbers are reviewed.
The external team handles the parts that need either specialist depth or sheer capacity. Technical audits, content production and link acquisition all fit that description reasonably well.
This also solves the oversight problem. Somebody internal understands the work well enough to tell whether the invoice reflects genuine progress, which is the single most common failure point in agency relationships.
Why Deliverable Counts Are a Poor Proxy
Most proposals are built around volume. Twelve articles a month, twenty links a quarter, a technical audit twice a year.
Volume is easy to price and easy to invoice against, which is precisely why it dominates the market. It is a fairly poor measure of whether anything is actually working.
The same twelve articles produce wildly different outcomes depending on what they target. A dozen pieces aimed at comparison and alternative queries behave nothing like a dozen aimed at broad awareness topics, even though the line item reads identically.
So ask for the reasoning behind the number rather than the number itself. Why twelve, why those topics and what happens to the plan if the first three underperform.
The answer tells you whether you are buying a strategy or a production line. Both have a legitimate place, but you should know which one is on the invoice.
The same logic applies to reporting. A monthly deck showing what was delivered is an activity log, whereas a deck showing what changed and what the team intends to do differently as a result is a strategy review.
Questions Worth Asking Before You Sign Anything
Ask who actually does the work. The people in the pitch are frequently not the people on your account. Ask directly, and ask how many other clients they carry.
Ask for a case study from a company at your stage. Enterprise results are close to meaningless if you are a twenty-person business, and the reverse is equally true.
Ask what they would do in the first ninety days. A good answer includes an audit and a diagnosis. A weak answer jumps straight to deliverables before anyone has looked at your site.
Ask how they measure. If reporting stops at rankings and sessions with no line drawn to signups or pipeline, you will struggle to justify the spend at renewal.
Ask about market coverage. Search behaviour and competition differ by country, and if you are expanding internationally then local language, local search habits and local competitors all need someone who has done it before.
The Honest Conclusion
There is no universally correct answer here, which is exactly why the question gets debated for so long. What separates the companies that get this right is not the choice itself but the clarity they bring to it.
Define the outcome, work out which capability you are actually missing, then resource that specific gap. Hire if the gap is ongoing ownership and product context. Bring in outside help if the gap is depth or capacity you cannot realistically build in time.
And if you genuinely do not know which it is, that is useful information too. It usually means the strategy work has not been done yet, and no amount of headcount or retainer will substitute for it.
Frequently Asked Questions
Is an agency more expensive than hiring in-house?
Not necessarily, once you account for the full cost of employment. A salary is only part of it, and you also need to factor in recruitment, tooling, training and the senior time required to direct a junior hire. The more useful comparison is total cost against the specific capability each option delivers.
How long before search investment shows results?
Meaningful movement typically takes several months rather than weeks, and the timeline depends heavily on competition, the current state of the site and how much authority the domain already has. Be sceptical of anyone promising rapid results in a competitive category.
Can a small software company do this without any outside help?
Yes, particularly early on when the priority is publishing genuinely useful content about a product you understand better than anyone. Outside help usually becomes worthwhile when technical complexity or the need for authority outpaces what the team can cover.
What is the most common mistake when choosing a partner?
Choosing on positioning rather than evidence. Almost every agency describes itself as full service, but most have one area where they are genuinely strong and others where they are merely competent. Identifying your own bottleneck first is the reliable way to avoid that trap.
