2. Channelswhere new users come from and what the traffic looks like
New-user source: Viral (Built-in sharing). Similarweb 2026-09: direct 40%, organic search about 45%, referrals 9%, France 100%. About 60% of brand keywords are misspellings of khosmos (khodmos, khsomos, cosmos devis), plus trade terms like plombier paris. The misspellings look like people hearing the name by word of mouth and then searching for it (speculation). The website menu has a referral reward: refer one peer and both get 2 free months. It also has free lead-generation tools such as a quote generator, a VAT calculator, and a company valuation estimator. The founder self-reported SEO, app store optimization, Facebook, Instagram, and TikTok as channels on TrustMRR, and the website also has YouTube. The 'Viral' classification comes from the referral reward mechanism plus the share of direct and brand visits; there is no data on how many users actually came from referrals.
