AI model development services
Level 3
Select and implement a model for a client's problem. The highest price band on this list, and the highest barrier — what sells is a research and engineering track record, not tool operation.

We have zero verified cases for this model, so no revenue range is shown. Publishing a figure without evidence is not something we do.
Who you sell to
- Companies needing an AI capability
- Research and prototype teams
How the money comes in
- Project engagements
- Surcharges by data type
Steps
- Write down the data types you have actually worked with — this route starts from experience
- Frame the portfolio as problem → chosen method → validation, not as output
- Fix scope and handover items (source, accounts, access) in the contract
- Buyers are companies, so get the invoicing requirements in place first
Risks
- Lowest replicability here. Degrees and track record are effectively the product
- Engagements are long, which makes running this alongside a job hard
- Preparing training data eats most of the schedule — price it in or you lose money
