You need exactly three recommendation letters. They must come from three different organisations, at least one of which is well-established in the UK or globally recognised. Letters from your direct managers, current colleagues, or outsourcing firm managers do not count. The most common failure mode is generic praise without specific, attributable examples.
The basic structure
Tech Nation requires three letters, written specifically for this application (not generic recommendation letters). Each letter should be:
- On official letterhead from the writer's organisation.
- Signed and dated within the last 6 months.
- Two to three pages of substance — long enough to give specific examples, not so long it feels padded.
- Written by the recommender themselves (not drafted by you and signed). Assessors recognise template language across multiple letters.
Who can write them — and who can't
- Senior leaders at OTHER tech companies who know your work
- Customers or clients who can vouch for your impact (especially with metrics)
- Conference organisers, award committee members, programme directors
- Open source project maintainers you've collaborated with
- Academic experts (for OC4 or research-heavy paths)
- Senior partners or investors who've worked with you
- Your direct manager at your current employer
- Anyone reporting to you
- Colleagues at the same company (current or recent)
- Managers at outsourcing or consultancy firms (Tech Nation explicitly rejects)
- Friends or family who happen to be in tech
- People who haven't worked with you directly
What each letter needs to say
A strong recommendation letter has four parts:
- 1. Who the writer is and why they can judge you. Their position, organisation, and how their work qualifies them as an expert in this field. Without this, assessors can't weight the letter.
- 2. How they know you and for how long. Project context, time worked together, in what capacity. "I've known X for 6 years through our collaboration on the Apache Kafka project" beats "X is a great engineer."
- 3. Specific examples with metrics. Not "X is a strong technical leader" but "X led the migration to event-driven architecture that reduced our latency from 800ms to 90ms, in a team of 8." Specifics are what convince.
- 4. A clear statement of your standing in the sector. Why they consider you a leader (or emerging leader). The letter should explicitly tie back to the mandatory criterion's language — "I consider X a recognised leader in the field of [X] because…"
Aligning letters to criteria
Each letter should reinforce a specific part of your application. A common pattern:
- Letter 1 — Mandatory criterion: a sector expert speaking to your leadership profile overall.
- Letter 2 — Optional criterion A (e.g. OC3): a customer or peer speaking to your impact in your strongest area.
- Letter 3 — Optional criterion B (e.g. OC2): someone from your voluntary work — a programme director, conference organiser, OSS co-maintainer.
Avoid three letters that all say roughly the same thing. Assessors read them as a set and want three angles, not the same angle three times.
UK connection
Tech Nation likes at least one letter from a writer who is UK-based or who works in a UK-recognised organisation. This isn't a strict requirement, but it strengthens your Stage 1 case considerably — it shows your reputation has reached the UK market.
