About this section
- What this shows
- Czech companies that already sell this, and firms nearby that sell something else.
- Why it matters to a builder
- A mature Czech seller means taking customers from an incumbent. Firms nearby still matter: the buyer may already pay them.
- How to read the score
- More points mean a more open field. 2/2 means no Czech company sells this, 1/2 only early ones do, 0/2 a mature one does.

The subsidy forms are Czech, so a foreign tool would have to be rebuilt around them before it could compete here.

3/3 · Easy
Makes it easier
- Small installation firms buy per seat out of their own money.
- No licence gates the work.
- The tool is ordinary software.
Makes it harder
- Four Czech vendors already sell installer software and the subsidy paperwork.
- One of them to about 20 solar firms.
- The subsidy rules were redesigned in June 2026.

Execution difficulty
About this section
- What this shows
- What stands between you and the first sale: who buys, what permission selling needs, what it must plug into, and whether it needs outside money.
- Why it matters to a builder
- It tells you whether a small team can start selling soon, or needs a licence, a certification or funding first.
- How to read the score
- More points mean easier to enter: 3/3 is easy, 0/3 very hard. It is not added to the Opportunity total, and local competition does not count here: that is Market gap.

Local competition does not change this level. It is covered under Market gap.
Suggested first moves
- Sit with ten small heat-pump and solar installers and time how long one quote and one subsidy application take each.
- Buy the two leading Czech installer tools, push one real job through each, and write down what they do badly.
- Build the heat-load calculation and the digital site survey first, so a firm can size, price and file from one tool.

Suggested first moves
About this section
- What this shows
- A few concrete steps to start with.
- Why it matters to a builder
- They are cheap ways to learn whether buyers will pay, before you build much.
- Sit with ten small heat-pump and solar installers and time how long one quote and one subsidy application take each. That time is the admin cost you price against. Ask each firm, too, whether its paperwork changed when the subsidy was redesigned this summer, and whether the new renovation pass has added work; see Why now.
- Buy the two leading Czech installer tools, push one real job through each, and write down what they do badly. The subsidy paperwork is already sold to these firms, so don't start there; see Market gap. What they do badly is where a new tool can win.
- Build the heat-load calculation and the digital site survey first, so a firm can size, price and file from one tool. The Czech tools barely touch those steps, while the German company sells them; see Market gap and Validated abroad. Today a firm sizes the system in a maker's tool and prices it somewhere else, so one tool saves it a step on every job.
- Add the renovation pass next, because it now stands between a homeowner and the retrofit money. The state pays for the assessment, which accredited specialists carry out, as Willing to pay shows, but no state money pays for the software, so the firm itself is the customer.
