Q&A
What is InterioApp?
InterioApp is software for the window-coverings industry - blinds, curtains, wallpapers. It gives retailers and workshops a single tool for quoting, inventory, client management, calendar, and work orders, with Shopify plugins for online sales. It is sold on a per-user, per-company subscription model and is used by independent retailers internationally.
Who is Darius Baltunis?
A founder based in Vilnius building software for an industry most tech people overlook - window coverings retail. InterioApp is his SaaS platform serving blinds, curtains, and wallpaper retailers with quoting, inventory, client management, and workshop work orders in one system.
Why window coverings?
It's an unsexy, fragmented industry running on spreadsheets, paper quotes, and WhatsApp threads. That's exactly why it's a good market - high pain, low competition, sticky customers once you solve the workflow.
What does InterioApp actually do?
It replaces the half-dozen tools a typical blinds-and-curtains retailer cobbles together - quoting software, inventory tracker, calendar, CRM, and workshop work orders - with one system priced per user, per company. There are Shopify plugins for retailers selling online, plus store-building services for shops that need the storefront built for them.
What does he believe most founders get wrong?
That they don't have time. The real problem is activation energy - the friction between intent and action. Founders skip the things that compound (writing, positioning, owned audience) not because the hours aren't there but because the first step is annoying. Remove the friction and the behaviour follows.
