What Calendos OÜ does
Calendos OÜ is a privately held Estonian private limited company (OÜ) founded in April 2024 and headquartered in Rakvere, Estonia. The company is a founder-led solo operation run by Õnnela Seinamets, operating as a 'virtual partner' offering three service lines: remote virtual assistant services billed at €30/hour for Estonian small businesses, a long-term financial resilience mentoring program for individuals, and training/education products for virtual assistants sold through the company's own e-commerce store. In November 2024 the company acquired the Assistendikool brand and related assets from Event Assistance OÜ (Liina Ostumaa), adding a sub-brand focused on VA training, including a €1,375 three-month Business Mastermind cohort capped at five participants.
The company has no proprietary technology platform; service delivery and commerce run entirely on third-party SaaS, including Thinkific (course delivery), Stripe (payment processing), Maksekeskus AS (Estonian payment gateway), Smaily (email newsletters), Canva (design), Zoom (video conferencing), and Slack (group communication). Distribution is omnichannel but small: the company's own website, personal-brand-driven social channels (LinkedIn, Instagram, Facebook), email newsletter, free lead-generation guides, and referral/word-of-mouth from existing SMB clients. Products are marketed to Estonia and EU member states, with physical fulfilment via Itella Smartpost parcel lockers.
The revenue model combines hourly professional services (VA support), individualized mentorship (financial resilience), and digital course sales (ChatGPT workshop recording at €54, VA Mastermind at €1,375). Customer acquisition is overwhelmingly testimonial- and referral-driven in the Estonian SMB segment, with no external institutional funding and a stated headcount of one. The business is bootstrapped and founder-owned, with revenue scale entirely bounded by the founder's available hours.
