xBerry

Remote R&D team building physical AI, including computer vision, embedded systems and robotics software, for manufacturers and logistics.

Clutch: 5.0 (11 reviews)Rate: 50–99 USD/hMin. project: 5,000 USD

Best for: Manufacturers and logistics companies that need computer vision, embedded AI or robotics software, from an MVP to a production system.

Verdict. A specialist, and the numbers back it up. If your product has a camera, a sensor or a robot in it, start here; if it is a web app, look elsewhere on this list.

Pros

• The only hardware-adjacent house in the top 10: vision inspection, robotics, edge AI, backed by an EU regional development grant.
• Profit of 3.5M PLN on 13.3M PLN of revenue in 2025, two private individuals as owners, 3 open roles on the boards.
• A 5.0 rating on Clutch from 11 reviews and a rare price signal on the site: a simple MVP starts from tens of thousands of euros.
• Employee reviews are positive (6 positive, 3 negative).

Cons

• Five GoWork reviews mention layoffs or cuts despite the positive overall tone.
• Most case studies hide the client; only a few are named.
• Founding year differs between the site, Clutch and the court register (2019 in KRS).

From their website and Clutch profile

• xBerry is the only hardware-adjacent firm in the set, working on robotics, embedded AI and vision inspection. The site shows an EU regional development grant badge (source).
• The FAQ gives a price signal, saying a simple MVP starts from tens of thousands of euros (source).
• The founding year conflicts, with 2016 on the site, 2015 on Clutch and 2019 in the KRS entry in our file (source).
• Most case studies hide the client (our Swedish partner, a leading vaccine manufacturer). Only Coco and Szajna are named, and CSHARK appears as a testimonial giver (source).

Best for: Automotive, logistics and pharma firms that need computer vision, AR in Unity, or a Node.js or PHP system around them.

• Only two of the six most recent case studies name the client, both GE Healthcare, and the other four are anonymized (source).

• DO OK is the only firm in the set with four ISO certificates, including 27018 for personal data in the cloud. It debuted on the Warsaw Stock Exchange (NewConnect) in 2017 (source).
• DO OK has offices in Tallinn and Aarhus, a Dutch branch since 2018 and a Danish one since 2019 (source).
• The founding year conflicts, with 2010 on the site and 2016 in the KRS entry in our file, likely the S.A. conversion (source).
• The projects listing renders empty without JavaScript, so case studies are reachable only via the industries page and direct links (source).

Who is not in the top 10, and why

What they charge

Check any agency yourself in 10 minutes

1. IoT projects span firmware, connectivity, cloud and a mobile app. Ask which of these the firm does in-house and which it subcontracts.
2. Find the legal entity in the National Court Register: the seat, the share capital and the shareholders. An office here with a seat in another city is a sales office, not a team.
3. Read the last financial statement on rejestr.io: revenue, profit or loss, and whether it was filed on time.
4. Check the VAT white list: active, and the name matches the contract.
5. On the Clutch list hover over the company link; a link through ppc.clutch.co is an ad. Then read the reviews themselves.
6. On GoWork read the employee reviews, not the stars, and look for layoffs and rotation.
7. Ask who exactly will work on your project, and check those people on LinkedIn.
