I'll help with the application

Half the job is describing the project the right way so it fits the EIS criteria. I help with that.

Talk about your application

Terms change - check eis.ee before applying. Baseline requirement: an Estonian company with 2-year average revenue of at least €50,000.

See which grant your company qualifies for

Enter a registration code - I'll show what's available to you under EIS.

This request may take a few minutes - we pull data from Inforegister and compute the result.

This is a rough estimate. The final call is EIS's.

How we work together

01

We talk

A free 30–40 minute consultation - by video or at my coworking space. What do you want to fix? What have you tried? Where are you stuck?

02

A plan

I write down what I'd do, what isn't worth doing, and what it costs. You decide if we keep going.

03

We build

I implement, train, or work alongside your team. Always on your real tasks.

04

I hand it over

The result stays with you and your team. Recordings, instructions, and a month of support included.

What clients say

A few words from the companies I've worked with.

"What used to take our team two days now takes ten minutes. The tool reads a tender, tells us whether it fits, and drafts the paperwork - and Sergei made sure we actually understood how it works."

Our tools

Riigi Tugiteenuste Keskus and EIS

"Based on report data analysis, reports our analysts built by hand for days are now ready in minutes, formatted to our template. The rollout was calm and practical - no hype, just working software."

Kent Hanson

Head of development, Forsta

"Our laser cutter and our accounting finally talk to each other. No more manual order entry, no more invoicing delays. Sergei found the saving and built a great solution."

Aleksei Saareväli

Head of operations, Industrial Metal

"After creating new AI tools our reporting services over all of Estonia, reports, analytics, procurement, and communication with Roads registry became much faster and more efficient. Sergei is a great partner to work with - he understands the needs of the business and finds the right solution."

What this looks like in practice

A few projects. Real problems, real numbers.

Manufacturing · Estonia

Steel structures factory

Problem

The machine ran separately from the accounting system. Operators typed in every order by hand - which meant mistakes and delays in invoicing.

Solution

I connected the machine and the accounting system directly. Data flows on its own: jobs in, actuals back.

0

manual data entry

−40%

order-to-invoice time

~€2,100

saved per month

Research Tech · Global

Forsta

Problem

Analysts spent days building client reports by hand - copying, formatting, cross-checking.

Solution

A program builds the report from the client's template on its own and hands it over for review.

Minutes

instead of days

more reports per person

−90%

formatting errors

GovTech · Estonia

Public procurement assistant

Problem

One tender is 50–200 pages of text. Reading and preparing it took days.

Solution

A tool reads the tender documents, checks whether it fits the company, and drafts the paperwork.

10 min

tender review (was 2 days)
