Built for Series C B2B SaaS · $20M to $80M ARR
By Series C, the category vocabulary in ChatGPT is being defined. Make sure your name is the default answer.
DerivateX is the AI search agency built for Series C B2B SaaS. We help CMOs build a defensible AI citation moat, the kind that holds through IPO due diligence and reads as category leadership in any board room.

The Series C Reality
Every classic moat is mostly built. The AI citation moat is not.
By Series C, your brand has Google share, your distribution motion is repeatable, switching costs are real. The four moats your board has been measuring for a decade are already mostly capped. The one moat with room to compound is the one nobody is reporting on yet.
AI citation share-of-voice is where category leadership gets contested in 2026. The Series C SaaS that owns it walks into Series D and the IPO window with a defensibility line nobody can match.

77 points of headroom. Illustrative category average. The AI citation moat is the only one a Series C SaaS can still claim in 2026 without fighting an incumbent for it.
The Series C Failure Mode
Scaling Series B is not Series C strategy.
The board narrative shifts from growth to defensibility. Most CMOs respond by scaling what worked at Series B at higher cost. The Series D term sheet does not reward execution velocity. It rewards moat depth.
The wrong bet
More of the Series B playbook, more expensively
Bigger budgets, bigger team, more agencies. No moat the board can name in three words.
Triple the brand spendAbove-the-line that compounds slowly and attributes poorly

Add a layer
The right bet
Add the AI citation layer to the stack you already run
You already have the agencies and the team. The work that compounds toward Series D is one layer up. We own that layer. They own theirs.
How DerivateX sits in your stack
We do not replace your agencies or your team. We add the AI citation layer that nobody else in your stack is wired to own.

The Slide Your Series D Deck Needs
Where you sit in your category, in AI search, right now.
Two axes the next investor will actually price. Category vision is already on your roadmap. AI citation share is the axis your board has not measured yet, and the one that decides whether you read as a leader or a contender.
Category Position Map · illustrative
Two axes · four quadrants · one trajectory
Most Series C SaaS sit in the lower-right quadrant: roadmaps that read as visionary, but invisible in AI search. The work is moving along one axis, not both. The trajectory above is the one that holds in the Series D room.

- Category vocabulary ownership strategy
- GEO technical foundation at scale
- Authority content production across the formats LLMs cite

Alternative · Brand strategy firm
$40K to $100K / month
Strategy-heavy, execution-light, no AI citation operating model. Built for category creation work, not citation defense.
Alternative · Large growth agency
$25K to $60K / month
Annual commit, account-manager pyramid. AI search bolted onto a Series B-shaped engagement, not a moat-level retainer.
Alternative · In-house brand defense team
$1.5M+ / year
Loaded cost for 6 to 10 specialists. 12 to 18 months ramp. AI citation expertise still rare on the market.
Why this fits Series C
An engagement that starts at $8,000/mo is small relative to the brand and analyst budgets it sits next to, and it earns its line item by owning the one layer none of those budgets are wired to deliver: AI citation share.
What Defensibility Looks Like in Production
Two growth-stage wins. Citation share that holds.
Not analogical proof. Both clients are growth-stage SaaS that picked the AI citation moat over scaling more channels. Both are seeing the kind of defensibility Series C narratives are built on.

Honest Answers
Four things every Series C CMO says first.
You have a stack, you have a number, and you have a board that wants the next moat named in three words. Here is how we earn the line item.
We already work with a larger agency. We don't need another one.
We partner with larger agencies, we do not compete with them. They handle the brand and demand work they were built for. We handle the AI citation layer, which is the layer they are not wired to own. Our Series C engagements typically sit alongside one or two named agencies that the CMO already trusts, with clean ownership lines on each side.
AI search is one channel. Too narrow for our scope.
It is not a channel, it is the new search layer. By Series C, your buyers research vendors in ChatGPT, Claude, Perplexity, and Gemini before they ever hit a SERP. Owning the answer there is not a tactic, it is whether you appear in the consideration set at all. The companies treating it as a channel are the ones that will lose their category position to the ones treating it as the moat it is.
Our category positioning is already set.
In Google, yes. In ChatGPT, the category vocabulary is still being defined for most B2B SaaS categories. The positioning work that was done for SERP rankings does not automatically transfer. The LLM understanding of your category is being shaped right now, and once it sets, the cost of rewriting it goes up every quarter. Most Series C CMOs are surprised by what their category currently looks like inside an LLM.
Our budget is allocated for the year. Maybe next cycle.
The AI citation moat is the only line on your strategy that loses value every quarter you wait. Re-allocation against an underperforming channel almost always beats deferring an entire year while a peer-stage rival stakes the citation share that should have been yours. We are happy to do a 30-minute teardown of where your category currently sits before you make the call.
