What I like best about Diffco is their real AI depth and honesty, even when it could mean less work for them. Our product reads receipts and extracts line items – the AI is the product, not just a feature. Diffco spent four months working on our models and the strategy around them, and the most useful thing they did was establish a way to measure accuracy. We now evaluate each change against that measurement before it ships, rather than assessing it by trying a handful of receipts. They were also willing to tell us when a problem was in our data rather than our model, which showed us they were focused on solving the actual problem, even if it meant less model work for them.

The combination of real computer vision depth and genuine ownership. They took the technical approach from scoping through delivery without us having to manage them, hit the three-month window on schedule, raised questions early instead of at the deadline, and handled a confidential engagement with discretion. They also stayed on to support the system after launch.

Their combination of deep AI/ML expertise and senior backend engineering. The team took ownership, suggested better solutions proactively, and worked like an extension of our own team through regular syncs and demos.
