Impact Summer Series, San Francisco

Growth in the age of AI

The fastest growing software companies did not out hire anyone. They built systems where growth creates growth. Here is what we walked through at INSEAD on September 17.

Session led by Jacco van der Kooij, with 2026 marketing benchmarks from Omar Akhtar of Benchmarker.

The short version

  1. Retention has held roughly flat while growth has fallen. The constraint is acquisition, so fixing churn will not fix the number.
  2. The era of abundant inbound is over. Search, email and social gave fifteen years of scalable access to buyers, and that was the anomaly.
  3. Sustained exponential growth needs outputs that become inputs. Without a loop, every extra dollar of pipeline costs more than the last one.
  4. Two loops move pipeline first. Virality generates leads. Advocacy generates opportunities.
  5. Modeled on a real company, one opportunity per hundred users nearly doubles ARR over twenty four months, and running virality alongside it compounds the effect further.
  6. Marketing budgets are being rebuilt rather than cut, with program spend overtaking people spend and AI now a standard line in the technology stack.

The problem

Growth is slowing because acquisition is breaking

Put retention and growth rate on the same chart over the last eighteen quarters and the shape of the problem is obvious. True retention, the brutal version a CFO recognizes, where revenue that was supposed to arrive and did not is simply churn, sits below eighty percent and stays roughly flat. Growth rate falls away from it. Flat retention cannot explain a falling growth rate. Acquisition can.

This matters because most remediation plans target the wrong side of the business. Teams tighten onboarding, add a save play, build a health score. All useful. None of it closes the gap that opened on the way in.

Search, email and social gave us a decade and a half of repeatable access to buyers. Spend more, reach more, generate more inbound. That was not normal, and it is not coming back.

Nothing stopped outright, which is the trap. The channels still work, slightly worse every quarter, well enough that nobody declares them dead and starts building the replacement.

The shift

From reasoning by analogy to reasoning from first principles

Revenue leadership is an unregulated profession. There is no bar exam, no license to lose. Leaders rise by accumulating best practices, and for twenty five years that worked, because the tooling evolved in small steps. Email became marketing automation, which became sequences, which became intent data. Each step was close enough to the last that pattern matching kept paying.

A step change breaks that. When the ground moves this far, the reliable move is to go back to the irreducible parts of the system, isolate the actual constraint, and engineer from there.

The same gap shows up in how companies are adopting AI. Most teams have crossed from literacy into fluency. People understand the tools and use them to get their own work done faster. Company performance has barely moved, because fluency is individual and productivity is structural.

The model

The funnel ends where the recurring revenue begins

A funnel describes acquisition and stops at the close. In a recurring revenue business that is where the money actually starts, so decisions made on funnel data are made on a partial view. The bowtie extends the journey through onboarding, adoption and expansion, and it gives you the second half where profit lives.

The bowtie model: lead generation, lead development and selling on the acquisition side, commit in the middle, then onboard, adopt and expand on the retention and expansion side
The complete customer journey. Most reporting covers the left half.

Software then grows along an S curve, the same curve that governs populations, because software propagates the way living things do. A feature is a seed and the user is the pollinator. The consequence is that the exponential middle of that curve has to be sustained for five to ten years, and you cannot sustain it by buying ever more inputs. The inputs run thin and their price goes up.

A growth loop is simply an output that becomes an input. It is the recirculation button in a car. Cool air you already paid for goes back through the system instead of pulling in heat from outside, and each pass gets cheaper.

The mechanism

Five loops, and the two that move pipeline

There are five growth loops worth designing: awareness, education, advocacy, retention and expansion. Expansion is the strongest of them in large enterprise deals and much weaker in high volume SMB, where new businesses appear and disappear at roughly the same rate. For pipeline generation specifically, the work sits in awareness, education and advocacy.

The shift underneath all of it is from leads to users. Traditional growth requires an ever increasing supply of leads, so campaigns must keep expanding to hold the line. Modern growth lets usage create more growth, because users generate impact, impact creates advocacy, and advocacy returns qualified opportunities to the front of the journey.

If you think you have no users, look again at who extracts the impact of what you sell. That person is your user, whatever the contract says.

What the loop is worth

Modeled on a real company with a real lead flow, holding everything else constant:

Chart showing ARR over twenty four months rising from 55 million on inbound alone to 75 million with virality, 107 million with advocacy, and 142 million with both loops running
ARR over twenty four months. White is inbound alone at $55M. The lower dotted line adds a twelve month viral boost at $75M. The heavier dotted line adds advocacy at one opportunity per hundred users at $107M. The solid line runs both loops together at $142M.

The sensitivity is the part worth sitting with. At one opportunity per hundred users the curve bends. At one per fifty it steepens. At one per twenty five it changes the trajectory of the company. These are not heroic conversion rates. They are the rate at which people who already get value from your product will say so, if you ask them properly.

The proof

Running the model against Harvey

Harvey went from roughly fifty million to three hundred and fifty million in ARR inside twenty four months, selling six figure deals into law firms with buying committees and integration requirements. Not a consumer product, and not a company that could hire its way to that number.

Reconstructing their growth from published figures and running it through the loop model reproduces their reported trajectory within two percent. The model suggests virality created the initial acceleration and advocacy sustained it. Virality created customers, those customers advocated, and advocacy extended the economic life of the original burst.

Look at what that advocacy actually consisted of over four months: a global firm publicizing Harvey powered products, a native integration with a document platform, the first firm launching custom workflows, a strategic alliance, a funding round, a firmwide rollout, then the first rollouts in two more countries, then an adoption milestone, then a law school program. Each event bought the next wave of attention. That is a campaign, not luck.

The work

Designing a campaign that compounds

Making this operational takes four steps, and the third is the one teams skip.

It is worth being honest about what this does not replace. Enterprise committees still buy the way they buy. The claim is narrower: for most software businesses, a designed loop now outperforms another increment of hiring, and almost nobody has built one.

The seller

The X3 seller

Every generation of tooling has produced a new kind of seller. Sequencing tools produced the SDR sending customized email at volume. Video conferencing produced the online seller, and made the conversation recordable, which produced an entire coaching category. The current generation is producing a seller who does roughly three times the work.

Three things define that seller. They do not stop working when they close the laptop, because their agents keep running overnight. They raise quality rather than only volume, which buyers experience as responsiveness, expertise and context. And they work across the whole journey rather than one stage of it, from first touch through expansion.

A seller touches win rate, cycle time, average sales price, discount level, churn and expansion. No other role touches all six. Improving the seller improves every one of them at once.

AI inside go to market runs roughly two years behind AI inside product, and the reason is structural. Product AI operates on a stable base. Go to market is variable, human and messy. That gap is closing now.

The benchmarks

What 253 B2B SaaS marketing leaders are actually doing

Omar Akhtar of Benchmarker presented fresh survey data from 253 senior marketing leaders in US B2B SaaS, fielded in June and July of 2026. The headlines, without the underlying numbers:

Full data, including the segment cuts, went to attendees with the deck.

Where to start

Five stages of go to market maturity

Most teams can place themselves on this ladder in about ten seconds, and the placement tells you what to build next.

1
ManualFounder led outreach and one off selling. Phone, email, a spreadsheet.
2
InstrumentedThe process enters the system. One motion, a CRM, list acquisition and cadences.
3
MultichannelTwo or three motions, each in its own funnel, each measured separately.
4
OrchestratedSignals and triggers decide priority using fit, contactability, timing and engagement. Human stays in the loop.
5
AI nativeSelf optimizing campaigns and agents running established channels without human operation.

The jump that matters is from three to four, and it turns on a decision about what the system is allowed to decide for itself.
