First mover advantage in AI is often presented as a reward for buying tools before your competitors. I think the answer is more specific: yes, a company can gain a head start by accumulating labeled process records and staff practice, but buying seats alone does not create that lead. In one support operation, agents with two months of tenure and AI access performed as well as agents without access who had more than six months of tenure.
AI adoption means buying or using a tool; the advantage I am arguing for is the record and know-how a company builds while people use that tool on real work. A record becomes more useful when it connects the original case to the AI suggestion, a person's correction and the eventual outcome. The full comparison of [competitive advantages for small businesses](/guides/business/competitive-moats-for-small-businesses) belongs in the guide.

## Labeled support conversations helped train the assistant
A support assistant trained on a company's own labeled conversations gave researchers a way to measure AI assistance in real work. Erik Brynjolfsson, Danielle Li and Lindsey Raymond studied 5,179 agents at one Fortune 500 business-process software firm's customer support operation, observing about 3 million chats. The assistant supported human agents during their conversations; the study did not measure a group of small companies. [Generative AI at Work](https://www.nber.org/papers/w31161) reports the results.
Agents resolved 14% more issues per hour on average with the assistant. The gain was 34% for novice and low-skilled workers, while the effect was minimal for experienced and highly skilled workers. That distinction matters to a company deciding where to start: an average can conceal a large difference between the person learning a process and the person who already knows its difficult cases.
The authors put the tenure comparison plainly:
> treated agents with two months of tenure perform just as well as untreated agents with more than six months of tenure
The comparison does not mean that every new employee will acquire every skill three times as fast. It concerns performance in this support operation, on the work the researchers observed. It does show why a process with frequent cases and an observable result is a better place to examine the claim than a general promise that AI makes everyone more productive.
Section 2.3 describes a system trained on the firm's customer-agent conversations, labeled with outcomes including whether an issue was resolved, how long it took and whether the agent was a top performer. The AI provider looked for conversational patterns predictive of resolution and handle time. My reading is that those labeled company records were a source of the assistant's usefulness: the system had examples of what good handling looked like in that operation. The paper does not measure how much of the gain came from the labels.
A company cannot assume that a pile of transcripts provides the same evidence. If a record contains a suggestion but no indication of what happened afterward, you cannot tell from that record whether the suggestion led to a resolution. The distinction between storing cases and labeling their outcomes is the part a buyer should inspect.
## Staff practice can persist when the assistant is unavailable
Staff practice with AI recommendations may leave workers faster even when the recommendations disappear. In the same study, the authors examined software outages that temporarily removed the assistant and compared workers' performance with their own pre-AI baseline. They read the results as suggestive evidence of durable learning.
Exposure time and engagement both mattered in that analysis. After about one month with the assistant, workers were little faster during an outage; after about three months, they handled chats faster than their pre-AI baseline. Workers who followed a low share of recommendations in their first month showed no improvement in chat times during outages, even after many months of AI access.
Adherence to recommendations rose over time, particularly among workers who had initially been skeptical. That pattern gives a manager something more useful to watch than whether staff have accounts: are people encountering suggestions, judging them and changing how they handle cases? A seat assigned on Monday does not answer that question on Friday.
The authors caution that outages were rare, were not necessarily random and produced noisy estimates. The outage findings suggest learning; they do not prove that every organization will retain the same gains. For a company of 10 to 200 people, the practical implication is to track practice over months and compare actual work with a baseline, while allowing for the possibility that a particular process produces no lasting gain.
## Accumulated cases put time between a starter and a follower
A company that records cases as work happens can accumulate evidence that a later starter does not yet have. The distinction is between the tool, which a competitor can purchase, and the sequence of cases the company has already handled and labeled. The latter is a history of particular inputs, corrections and outcomes.
Two bodies of research make the timing argument more precise, although applying either to a company's AI-assisted process is my analogy. Theodore Wright proposed in 1936 that cost falls as a power law of cumulative production. In a [study of 62 technologies](https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0052669), Nagy, Farmer, Bui and Trancik tested six forecasting laws: Wright's law produced the best forecasts, with Moore's law close behind.
That research concerns the cost of technologies, not the rate at which a particular company learns to process invoices. Its useful analogy is that the count of cases handled can matter more than the date on which a subscription began. A dormant tool has had calendar time; the people using it have not necessarily had practice or produced labeled cases.
Dierickx and Cool's research on [asset stock accumulation](https://doi.org/10.1287/mnsc.35.12.1504) supplies a second analogy. They describe critical resources as accumulated rather than acquired and identify time compression diseconomies as a limit on imitation. My plain-language reading of that term is that spending more to hurry an accumulation process does not guarantee the same stock in half the time.
Consider an openly hypothetical company of 40 people that handles 400 items a month in one AI-assisted process and logs each item's correction and outcome. By my arithmetic, six months produces 400 × 6 = 2,400 labeled cases. A competitor that starts logging six months later has zero cases in that new log on the same date.
:::figure{src="/blog/art/en/ai-advantage-window-curve.75fdbf82.webp" alt="A falling tool cost curve beside case records accumulating earlier for one company than for a later starter" width="1440" height="810"}
Notice that tool costs fall for both companies, while each record starts accumulating when its company begins logging. On the same accumulation slope, the later starter remains behind.
:::
The hypothetical does not guarantee that the first company's 2,400 cases are accurate, representative or suitable for training a model. It also does not prevent the follower from finding existing records or processing more cases per month. The narrower claim is enough: buying access to the same tool on the later date does not purchase the first company's six months of labeled history or its staff's practice.
## Workflow investment can precede a visible return
Workflow changes can require investment before their value appears in a productivity measure. Brynjolfsson, Rock and Syverson's [Productivity J-Curve research](https://www.nber.org/papers/w25148) describes complementary investments around general purpose technologies as intangible and poorly measured. Their model predicts productivity growth can be underestimated in the early years and overestimated later.
For an AI-assisted process, a correction log and time spent learning to use it are examples of the kind of investment I would examine through that lens. Staff must record outcomes and review suggestions before the company has a useful history to inspect. The J-curve is a reason to measure those activities alongside output; it is not evidence that every project with a slow start will eventually pay off.
The adoption figures also suggest that using AI and changing a workflow are different stages. Census BTOS found that 17.2% of US employer businesses reported AI use in any business function during the reference period 17 to 30 November 2025. The corresponding share was 24.6% for 21 September to 4 October 2026, a rise of 7.4 percentage points by my subtraction. Those are business-level shares, and the comparison uses the current question wording.
Among AI-using firms, about 15% developed new workflows and 64% reported no organizational adjustments, according to unreviewed [Census working paper CES 26-25](https://www2.census.gov/library/working-papers/2026/adrm/ces/CES-WP-26-25.pdf). Separately, 7% of AI-using respondents in the Fed's Small Business Credit Survey said AI was fully integrated into business functions; that survey is a convenience sample.
The three measures ask different questions, so they should not be combined into a single share of firms with a durable advantage. Taken together, they support a narrower observation: reported use is not the same thing as a changed workflow or full integration. The [AI adoption statistics by company size and survey](/blog/state-of-smb-ai) provide the wider comparison.
## Can competitors copy what early adopters built?
Competitors can copy purchased AI capabilities, and waiting can give them a lower price and a clearer view of what failed. The strongest argument for following is that early buyers pay to discover which tools and processes are worth keeping, while later buyers can select from a cheaper set of options.
[Epoch AI's price analysis](https://epoch.ai/data-insights/llm-inference-price-trends), published 12 March 2025, found declines of 9x to 900x per year for a fixed performance level across the milestones it examined. The price of GPT-4-level performance on a set of PhD-level science questions fell by 40x per year. Epoch also cautioned that its fastest observed drops occurred in the preceding year and might not persist.
There is no general rule that pioneers win. The [UCLA Anderson Review's recap](https://anderson-review.ucla.edu/how-first-mover-advantage-once-unquestioned-lost-its-grip-on-entrepreneurs-and-business-researchers/) of Golder and Tellis's 1993 Journal of Marketing Research paper says nearly half of market pioneers failed. The review also quotes researcher Marvin Lieberman on the limits of a first-place claim:
:::quote{cite="Marvin Lieberman, UCLA Anderson Review"}
we certainly can't argue being first is better. We can argue that being first is better in some circumstances.
:::
Broad use also has to clear a modest evidence bar. In the March 2026 revision of [Still Waters, Rapid Currents](https://www.nber.org/papers/w33777), Humlum and Vestergaard studied 25,000 workers across 7,000 Danish workplaces and 11 occupations. Adopters reported saving about 3% of work hours, while the researchers ruled out effects on earnings and recorded hours larger than 2% two years after ChatGPT's launch.
In my view, the counter-argument is right about anything a company only buys: seats, a chatbot widget or prompts give a competitor a purchase to copy, and buying early can mean paying more for the same capability. It stops at the company's accumulated record and practiced staff: a follower can buy the tool, but that purchase does not supply the earlier company's months of cases or practice. The [case against rushing into AI](/blog/case-against-rushing) examines the reasons to wait in full.
## Test one process on Monday
My decision rule is that an AI head start counts only if a process produces at least one asset a follower cannot buy later. For this rule, those assets are a labeled record of the company's own cases, staff practice measured over months, or a timed baseline for comparison. If a project produces none of the three, I think waiting costs little: there is no accumulated record, practice measure or baseline to leave behind.
A labeled case should connect the input, the AI suggestion, the person's correction and the outcome. A practice measure needs an observable period of use, not just a list of assigned accounts. A timed baseline needs a defined measure, such as time per item, taken before or alongside the change so that a later comparison has a reference.
On Monday, spend ten minutes on the process where your company uses AI most. Ask whether you can export the last 90 days of items with what the AI suggested, what the person changed and the outcome. Open the export and check the fields on actual cases; a dashboard showing only the number of requests cannot answer the question. For wider readiness checks, use the [AI readiness test](/blog/ai-readiness).
If the export lacks those details, add the three fields to the log this week for one process: AI suggestion, human change and outcome. Assign someone to review the corrections, and keep the timed baseline with the process record. [Iron Goo's operations service](/services/operations) builds and runs AI automations with audit logging on every action and sets up the correction and outcome log.
