Goes furthest in Israel — 1 companies
This says who will engage, not what your scope should cost. A budget that reaches most of the market still buys very different things depending on what you are building.
Who is focused, and who has proved it
Horizontal: how concentrated a company is on Smart Contract. Vertical: how much checkable evidence stands behind it. 13 of 30 companies are plotted — the rest have fewer than 2 evidence signals, so placing them would be guesswork.

How a company is placed
- Focus is the inverse of how many categories a company claims, blended with the share of its portfolio tagged with this one. A firm listing three technologies is concentrated; a firm listing forty also appears here.
- Proven delivery adds published reviews (to 20), portfolio projects (to 25), Ahrefs Domain Rating (to 60) and years listed (to 10). Each is capped so no single signal carries a company to the top.
- Positions are relative to the other companies on this page: the median company sits at the centre of each axis, so a quadrant boundary means "ahead of half the companies listed here". Raw scores are in each bubble's tooltip.
- Deliberately excluded: the star rating, which sits in too narrow a band to separate anyone; the editorial rank, which is a hand-assigned sort weight; and paid verification, which does not move anything on this chart.
- Leaders:
- Concentrated on this work and with the record to show for it.
- Specialists:
- This is most of what they do, but the public evidence is still thin.
- Established generalists:
- A substantial track record, spread across many categories.
- Emerging:
- Building both focus and evidence.

Malinovsky Digital Agency
Malinovsky has helped our business tremendously. We were faced with the challenges of expanding our online presence in the US, Canada, Western Europe and UAE, promoting React Native and Python development, optimizing Google search and moving from Google Ads to organic results. Despite the large number of tasks and limited resources, Malinovsky found a great combination of marketing activities. Their expertise in PPC and SEO for IT companies led us to grow advertising and then search traffic within months. Within a year, we generated 200 leads from targeted regions. Our Celadon company expanded geographically and began to embrace new technologies in AI and ML. This expansion led to the launch of a new website. The team's proactivity, commitment to understanding the details of our business and meeting deadlines was impressive. We have been working together effectively for over 5 years.
