Optional criterion 3 asks for a significant technical, commercial, or entrepreneurial contribution to the field as a founder, senior executive, board member, or employee of a product-led digital technology company. Of the four optional criteria it is the most frequently used, and in the endorsed applications we have analysed it follows the most consistent formula. The formula starts in the first sentence: endorsed OC3 documents open with the biggest verifiable number in the story, and everything after that sentence exists to make the number credible and personal.
A composite of the endorsed pattern: “In 2022, as Director of Product, I led the strategy, design, and implementation of a six-month project in a mobile game generating $200M in annual revenue, resolving a memory constraint that had capped monthly events at four, and adding $12M in annual revenue.” Role, action, stakes, mechanism, result, in one sentence. The weak version of the same story, and we have seen it in refused applications, reads: “I worked on a project that helped increase revenue.”
OC3 is about the person, not the company
The critical distinction, and the one panels test hardest, is between OC3 and OC1. OC1 evidence proves the business is real: accounts, client lists, revenue. OC3 evidence proves the applicant personally did something significant inside a business. The guidance warns that submitting the same evidence for both criteria “may not be sufficient if it does not meet these different requirements.”
In practice, endorsed applications kept the two apart on every dimension:
| Dimension | OC1 | OC3 |
|---|---|---|
| Focus | The business generates revenue | The person made a specific contribution |
| Attribution | Company-voiced | First-person throughout |
| Structure | Financial statements | Context, action, result |
| Proof | Invoices, accounts, client lists | A/B tests, architecture diagrams, before/after data |
| Scope | The whole trajectory | One project or initiative |
The attribution rule matters most. OC3 documents that endorsed applicants wrote are aggressively first-person: “I led,” “I designed,” “I negotiated,” with the team acknowledged but the applicant’s decisions kept distinct. Documents that dissolve the applicant into “we” leave the assessor with nothing to endorse.
The three-page architecture
Endorsed OC3 documents almost universally followed a context, action, result structure across their three pages:
- Page 1, context. The problem or opportunity, with the stakes quantified: the revenue at risk, the market being entered, the cost of the constraint. Strong documents establish the stakes with an internal artefact, a dashboard, a metric chart, a problem statement.
- Page 2, action. What the applicant specifically did, usually as numbered steps: the analysis, the design decision, the build, the rollout. Architecture diagrams, feature designs, and project records appear here, each captioned with the applicant’s role in producing them.
- Page 3, result. The measurable outcome: A/B test results with the uplift stated, before-and-after revenue or usage comparisons, the calculated annual impact, and any recognition the work received. Endorsed documents convert results to GBP where possible and show the arithmetic.
Two sub-tracks exist within the criterion. Technical-track applicants (engineers, data scientists, technical leads) evidenced code-level and architecture-level contribution: repositories, design documents, employer letters confirming the applicant built the core system. Business-track applicants (product, growth, commercial roles) evidenced growth mechanics: the pipeline they built, the pricing change they drove, the market they opened, always with the delta attributed to the specific intervention.
What made the numbers survive scrutiny
Panels read OC3 numbers sceptically, and the endorsed corpus shows three habits that answered the scepticism:
- Attribution chains. The document connects the applicant’s action to the metric through a mechanism, not an assertion. The event cap was four, the memory system removed the cap, events went to nine, each event’s revenue is known, therefore the added revenue is calculable.
- Third-party corroboration. App analytics platforms, payment dashboards, signed contracts, and employer letters carried numbers that would be self-declared otherwise. Where an independent source existed for a figure, endorsed documents used it.
- Honest boundaries. Endorsed documents state what the applicant did not do (“the sales team closed the contracts; the pipeline and pricing structure were mine”), which makes the claimed contribution believable.
The failure modes
From refused applications and review submissions: impact claimed at company level with no personal mechanism, results with no baseline (a number with nothing to compare it to), evidence duplicated from OC1 with the wording lightly changed, and documents that spend two pages on context and half a paragraph on results. The three-page limit is absolute, and endorsed documents spent most of it on action and result.
One more pattern from the refusal corpus: investor-type profiles claiming OC3 through the success of portfolio companies. Panels have refused this framing consistently, because the contribution belongs to the companies’ builders. Our anatomy of an investor-profile refusal reads that reasoning in the panel’s own words.
