Prague Mustangs

Player, board member, author of mustangs.cz

The Prague Mustangs have played American football since 2009 and compete in the Czech leagues. The club runs a men's team and a youth programme: flag football from age 6 and tackle football from age 16.

I play for the team, I am a member of the board, and I designed and built mustangs.cz.

Practice is on Tuesdays and Thursdays. New players are welcome.

Where I work: Symfio and ConradReport.

Symfio

Marketing Manager

Symfio is a Prague company that makes software for financial reporting, consolidation and planning. It connects to the accounting systems a company already uses, such as QuickBooks, Odoo, Business Central, Pohoda and Helios, and builds reports, dashboards and forecasts from that data.

Customers include holding companies, investment funds and growing businesses. Features cover consolidation with intercompany eliminations, budget versus actual, cash flow forecasts, and drill-down from a report to the source document.

I am the Marketing Manager. I am responsible for positioning, campaigns and content aimed at CFOs and finance teams.

ConradReport

Editor in Chief

ConradReport publishes financial news based on public company filings. Each article reports figures such as net profit, revenue, operating margin, interest cover, equity and cash, and cites the source of every number. Symfio computes the figures.

It covers companies in Czechia, Slovakia, Norway, Sweden, the UK, Ireland, the US and Canada, along with startups and investment. There is a weekly newsletter called Week in numbers. The site is in English and Czech and is written for controllers, accountants and founders.

Articles are drafted by Conrad, Symfio's AI controller. I am the editor in chief and decide what gets published.

pricebeeper.io

Author

Pricebeeper monitors competitor prices for online shops, retailers and brands. It finds sellers of your products on Google Shopping and Amazon, matches them by barcode, brand and title, and tracks their prices by country and region in 67 countries.

You get alerts for price drops, sales, target prices and competitors going out of stock. It keeps price history, scores each seller, and shows price gaps between regions. Repricing rules suggest new prices and MAP monitoring flags resellers who advertise below your minimum price.

It imports catalogs from Shopify, WooCommerce, CSV and product feeds, and has a REST API, webhooks and Slack and Teams notifications. The free plan covers 50 products.

claribi.com

Author

claribi.com answers questions about your business data written in plain English, for example how ad spend compared to new revenue last quarter. The answer comes back as a chart, a table and a short explanation.

It connects read-only to more than 160 tools, files and databases. Each source gets a dashboard automatically. It also writes reports with findings and risks, and makes forecasts with prediction ranges.

All calculations run in code. The language model only plans the queries and writes the text. Developers can use the REST API or the MCP server.

demander.to

Author

You give demander.to the URL of your product. It reads your website, identifies likely buyers, writes the messaging, designs ads and posts in your brand, and runs campaigns on paid ads, organic social and e-mail.

Budget moves toward the campaigns that create opportunities in your CRM. You set the limits: six levels of autonomy, daily and monthly spend caps, a kill switch, and an undo log for every change.

It is made for B2B software companies, agencies and small marketing teams, including those selling in Central and Eastern Europe.
