Take on a company's real problem,
then apply with the record.
CoSprint is a job application platform built on real work: you take on a problem a team at the company you want is actually working on, with virtual colleagues and AI, and your ideas, your work, how you work and how you use AI stay on record.

Keep it on your passport
What you made, how you work, how you use AI.
More to show than your CV can hold?
Cover letters, AI skills tests and AI interviews leave out how you think and how you work. No experience needed — one of these is enough.
You'd rather show how you use it on real work than score it on a test.
No experience yet, but a problem makes you want to try things.
You want to see the problems a company you like is really working on.
Short on experience, long on how you work.

Use AI freely. How you use it is the skill.
AI isn't blocked. What you handed it, how you briefed it and where you caught it wrong stay on your record, read against CoSprint PAIR.
- Can you build the weekly conversion table from this file? I'll work out the cause myself.1
- Done. Coupon redemptions fell in September — the coupon cut looks like the main cause.
- Coupon use is flat week to week. That can't be it.3
- Look at the week of the 3rd on its own, app installs only, and leave out returning users.2
- I've checked the push outage against Dasol's logs.
- The Android share I couldn't confirm, so I've flagged it.4

Your record — shown as much as you choose
Every sprint you hand in builds your passport: which company, which problem, what you made, how you work and your AI fluency. Only you see it, until you open it to companies.

What stays
Sprints you took on, what you made, how you work, your AI fluency (PAIR).
What doesn't
A company's scores and decision — that's their call, and it stays with them.
Who sees it
Only you by default. Open it when you want to.
Questions before you start
Does it cost anything?
No. Company sprints and CoSprint challenges are both free to take part in.
Can I use AI?
Yes. It isn't blocked — it's recorded. What you handed to AI and how you checked it becomes part of your AI fluency record.
How is this different from an AI skills test?
A skills test reads you through set questions or games. In CoSprint you take on a company's real problem, and what you made and how you got there are kept as they happened.
How is it different from a competition or an extracurricular?
A competition judges the final entry. In CoSprint you work a team's real problem with virtual colleagues and AI, and your passport keeps how you worked it out, not only what you handed in.
Are the colleagues real employees?
No. They're virtual colleagues built from the sprint's material. They give you facts and figures; the judgement is yours.
Does handing in mean I've applied?
No. What you hand in stays on your passport and also reaches the company that opened the sprint. Whether to apply for the role is one more choice, at the end.
How long does it take?
Each sprint has a window set by the company. Within it, you work on your own schedule.
Do I need experience?
No. What stays is how you read the problem and worked it through — your ideas and your approach included.
If I'm not picked, will I know why?
A company's assessment and decision aren't shared. What you made, how you work and your AI fluency record stay on your passport.
How is a passport different from a portfolio?
A portfolio is the work you chose to show. A passport keeps work done on real company problems, along with how you did it — your working style and AI fluency.
Who can see my passport?
Only you, by default. You can open it to companies when you want to.
What are CoSprint challenges?
Tough problems CoSprint picks itself, not tied to any one company's hiring. Take one on whenever you like; your record stays on your passport.
