"Turned our AI accuracy from a feeling into a number we can actually manage"

5/5

What do you like best about Diffco US, Inc.?

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. Review collected by and hosted on G2.com.

What do you dislike about Diffco US, Inc.?

Nothing that affected the work. Some of the early sessions were more strategic than I expected when I thought we were starting on implementation. In hindsight, that order made sense, but it took me a little while to see why. Review collected by and hosted on G2.com.

Recommendations to others considering Diffco US, Inc.:

Bring them in on the strategy, not just the build. The most valuable conversations we had were about what not to use AI for. If you hand them a fixed implementation task you'll get a good result, but you'll miss the part where they save you from work you didn't need to do. Review collected by and hosted on G2.com.

What problems is Diffco US, Inc. solving and how is that benefiting you?

Extraction accuracy is central to our value proposition, and before this we had no reliable way to know whether we were improving it. Diffco worked on our model and established a framework to evaluate its accuracy, so our engineering effort now goes where the errors actually are rather than where we assume they are. They also continue to support the AI side of our product, which means we don’t have to manage that work or maintain that expertise on our own. Review collected by and hosted on G2.com.

"Delivered a client-facing computer vision project in three months with almost no management overhead"

5/5

What do you like best about Diffco US, Inc.?

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. Review collected by and hosted on G2.com.

What do you dislike about Diffco US, Inc.?

Nothing that affected the outcome. We'd have liked slightly more written documentation handed over at the end - most of the context lived in our calls and syncs - though they were always available when we had questions afterward. Review collected by and hosted on G2.com.

Recommendations to others considering Diffco US, Inc.:

If you're an agency or platform company subcontracting technical work, they're a safe bet - they operate at a level you can put in front of your own client. Give them room to own the technical approach rather than handing them a fixed spec; that's where they add the most value. Review collected by and hosted on G2.com.

What problems is Diffco US, Inc. solving and how is that benefiting you?

They enabled us to take on a technically demanding AI and computer vision project that we couldn’t have staffed internally within that timeframe, and to deliver it under our own name without taking on quality risk. Our client—an image generation startup—needed the AI and CV layer built in three months. Diffco owned the technical approach end to end, and their continued support after delivery means the maintenance burden doesn’t fall back on us. Review collected by and hosted on G2.com.
