How to hire an ML engineering agency (2026)
What to ask, what to look for in a proposal, and the questions that separate a real ML team from an LLM wrapper shop.
ReadYour sales team keeps hearing the same question and keeps giving the same answer about the roadmap. Meanwhile a competitor ships a scoring feature that is thin but demoable, and the comparison sheet starts going against you.
One senior ML engineer is a long search and a permanent line on the payroll for what might be two features. And a single hire has no bench - the moment they take a month off, the model has no owner.
Shipping a prompt as a feature works until a customer's security or data team asks how the number is derived, where the data goes, and what happens when the provider changes the model. That review is where thin AI features die.
Every deployment is slightly bespoke. A generic model trained on one customer's data does not transfer, and building per-customer models by hand does not scale past a handful of accounts.
A deployable service that takes your schema in and returns scored records out. Your name on it, your docs, your support. Under NDA we do not appear anywhere in the deliverable or in our own portfolio.
One pipeline, many tenants. Each customer's model trains on their own data with your shared feature definitions, so accuracy is per-account but the operational cost is one system, not N systems.
Every score comes back with the features that drove it. This is what your customer's analyst needs to trust the number, and what your customer's compliance reviewer needs to sign it off.
We map each tenant's data model to a shared feature card once, at onboarding. Adding a customer becomes a mapping exercise rather than a modelling project.
Scheduled retraining per tenant, distribution monitoring on inputs and outputs, and alerting when a model starts drifting. Delivered as runnable infrastructure with a documented runbook.
Full source, feature pipeline, training scripts, evaluation procedure, and calibration step documented. You can take it in-house whenever you want. The retainer is optional and stays optional.
We pick one of your customers with real data volume and scope a single model against their schema. This is where we find out whether the feature is viable at all, before you have committed roadmap or told anyone it is coming. Two to four weeks.
Model, adapter, service, and monitoring built against that tenant, then run in shadow mode inside your product so you see live behaviour with nothing exposed to the customer. Four to eight weeks depending on schema complexity.
Second and third tenant onboarded through the adapter layer to prove the mapping approach holds. Then documentation, runbook, and knowledge transfer to your engineers.
Thirty minutes to work out whether the feature you want to sell is supportable by the data your customers actually have. If it is not, we will say so on that call.
