Model a warehouse analysts won't hate
A team writes the same 200-line query every week. Design the star schema that ends that.
View brief →Find the leak in a D2C funnel
Conversions fell 3.2% and marketing blames product. Find where people actually drop off, and prove it.
View brief →Ship an agent that books a real workflow
Three tools, one messy task, and a scorer that fails you the moment your agent invents a tool call.
View brief →Deploy it, then watch it drift
Serve a trained model, replay three weeks of traffic, and catch the drift we hid in week three.
View brief →Build a RAG that refuses to hallucinate
900 pages, 60 questions, 12 with no answer in the corpus. Score points for saying "I don't know."
View brief →Predict churn without cheating
Four columns leak the answer. Find them, drop them, and still beat the honest baseline.
View brief →Make a flaky pipeline idempotent

What is a PrimrIQ challenge?
An open project challenge: one brief, one dataset and one deadline, set and reviewed by the mentors who grade our programmes.
Do I need to pay to participate?
No. Registering, entering and getting feedback cost nothing, and you don’t need to be enrolled in a course.
Can I add this project to my portfolio?
Yes. Your submission is yours. We only share it publicly if you say yes.
Which tools can I use?
Whatever you’re comfortable with, unless the brief names a stack. SQL, Python and Excel all work for the analytics challenges.
Is there a minimum skill level?
Each challenge lists its level. If you’re new, start with a Beginner challenge: you’ll get the same written feedback as everyone else.
How do I submit?
From your challenge dashboard, before the deadline. Your login details are in your registration email.
Can I work in a pair?
Yes, solo or in a pair. Both of you get every reward your entry earns.
Are late submissions accepted?
No. Submissions close at the time shown on each challenge (IST). After that, past challenges stay open for practice.
Where can I ask questions?
Reach us through the contact page and the team will get back to you.
How are winners chosen?
Blind, by the mentors who grade our programmes, against the criteria listed in each brief.
When are rewards issued?
After results are published. Learning vouchers and credits appear in your dashboard and are valid for 90 days.
