Real systems. Real numbers. Receipts attached.

Every kratt case study below is in production, with the live URL attached wherever the work is a public site. Named clients are RehvidTartus24, Matcha Bear and ProfiElekter. The rest is our own work: our product diil.ai and the internal systems we run on, linked wherever they can be inspected publicly. Numbers we cannot re-measure are stated as claims we do not make, rather than dressed up as metrics.

Selected work.

A selection of the work we can show in public: storefronts, platforms, AI and operating systems. Not every project is listed here. Some run inside private company tools, and some clients prefer not to be named.

An Estonian corporate finance firm

An Estonian corporate finance firm sends cold email from separate domains in its own name. Every mailbox warmed up before the first campaign email, and every address on the list was verified before anything was sent to it. The page describes the build and does not publish the campaign’s results.

RehvidTartus24

A tyre shop in Tartu got 29,364 new products in the WooCommerce shop it already had, all created by 13 October 2026: 4,670 tyres, 24,438 rims and 256 motorcycle tyres. Buyers can search by number plate, through the shop’s own connection to the state vehicle register, which kratt built and integrated. Stock and prices come from the wholesaler every two hours from 06:00 to 20:00, and the lists, product pages and homepage have a new look. The page shows public counts and build receipts and claims no sales lift.

Matcha Bear

A Shopify rebuild around the identity Matcha Bear designed in-house: a preparation ritual that plays as you scroll, bundles and a subscription in the buy box, and a partner map of the cafés and shops that serve it. Live on matchabear.eu, with build evidence rather than a claimed sales lift. On 14 October 2026 the store’s partner map listed 41 locations, one of them in Madrid.

ProfiElekter OÜ

Seventeen years of real projects (Swissotel, Hilton, a 50,000 m2 industrial LED refit) sat invisible on a 13-year-old Weebly site. We migrated it like-for-like first, losing zero ranking pages, then grew it into a 132-URL multilingual search system. The useful proof is the technical SEO layer, structured documentation, and audit trail.

The kratt lead engine

Manual prospecting capped our own pipeline. So we built an engine that finds businesses, scores their websites with AI, and generates a personalized landing page per prospect. It feeds our own outreach.

The content machines

A four-loop pipeline that turns a codified brand DNA file into finished ads, carousels and campaign frames. It fingerprints every combination it fires and refuses to repeat one inside 30 days. 66 machine-rendered creatives across 6 brands so far.

The automation spine

Kratt runs a shared n8n automation instance instead of scattering one-off scripts across laptops. It sits behind a public webhook front door and a private admin path, with Postgres state, execution pruning and runbook limits. The public story is architecture and operating discipline, with secrets and endpoint details deliberately withheld.

Registry radar

A daily Äriregister diff watches Estonian company data for new registrations, new VAT numbers and liquidation signals. A second list-hygiene job reconciles the live call list against that snapshot so sales knows who to call and who not to touch. It runs read-only until a human decides the signal quality is worth writing into CRM.

Backup and restore test

The backup loop dumps the operational stores that would hurt if the box died, then verifies row counts instead of trusting file existence. A separate weekly restore test loads those dumps into a throwaway Postgres and destroys it after proving the data loads. It is continuity work with failure alerts, retention rules and known gaps stated plainly.

Case Studies · FAQ

How we report results, and how to vet us.

Three answers most procurement teams ask before they buy.

What is kratt?

kratt is an audit-led AI systems partner in Tallinn that finds where a business loses time, money, or operational context, then builds and runs the system that fixes the highest-value part. The case studies on this page list systems that actually run, with the live URL attached wherever the work is public.

How does kratt measure case study results?

The systems we run on ourselves report numbers counted from our own logs. If we cannot check a number again, we do not show it as a result. We do not cherry-pick numbers or choose a time window that flatters them.

Will kratt share my case study publicly?

Only with written approval.

kratt

kratt takes AI in companies from an initial idea to a reliable system. Based on the audit, we define where AI pays off and start development where the return is highest.
