FREQUENTLY ASKED QUESTIONS
-
How fast can we start?
The short answer: fast. Most projects launch in 2 days, and initial samples are typically ready in under 72 hours depending on the complexity. We work with your current data formats and processes, so you don't need to change anything.
-
Can your developers work on our tooling?
Yes. If you prefer, we provide both API access and custom integrations. We can plug into your existing workflow whether you're using a third party platform or you own proprietary platform. -
Can we pilot with a small batch first?
Yes! Most clients start with a pilot project—usually a few hundred evaluations across different problem types. This lets us calibrate our process to your needs and demonstrate our quality before scaling up. -
How do you handle data quality issues?
Data quality is the most important issue that we focus on. To have a detailed conversation about our processes and systems we use to ensure high-quality data, get in touch with our team.Can we pilot with a small batch first?Yes! Most clients start with a pilot project—usually a few hundred evaluations across different problem types. This lets us calibrate our process to your needs and demonstrate our quality before scaling up. -
How involved do we need to be in the process?
As much or as little as you want. Some clients are hands-off and just want the data, others want to deeply collaborate on evaluation criteria. We're flexible—though we do recommend initial calibration sessions to align on quality standards. -
How quickly can you scale up?
Our technology allows us to scale up and down extremely quickly. We can typically spin up new evaluation capacity within 48 hours, and can onboard hundreds of new developers to your project every week. -
What languages/frameworks can you handle?
Our network of 400,000+ experienced engineers includes experts in every coding language that exists.
