Milluu is a proptech end-to-end digital platform designed to simplify the experience of renting a property, completely taking care of every step of the process - from the first to the last day of the rental period. The landlords find in Milluu the Instant Rent option that guarantees the rent for 12 months and first payment in 30 days after the sign-up in the platform! With a fully digital onboarding journey, the owner is renting his apartment without the stress of dealing with the real estate agent (one or more), interrupting his daily schedule to take calls from interested potential tenants, managing each visit, helping the tenant to get installed in the apartment…and the list continues. Milluu does all these tasks and more: tenant financial risk analyze, utilities payment management, technical emergencies insurances, etc. The tenants have access to a portfolio of high quality & ready-to-move apartments and a fully digital renting experience: sign the contract or pay the rent and utilities expenses in the app. Additionally, the rental agreement includes an insurance policy for all properties in the apartment as well as an emergency technical assistance package for any failure of plumbing, electrical or district heating.

SideQuestr — the map powered by your group chat. Your friends know where the good stuff is. The hidden rooftop bar, the park with the best sunset, the coffee shop you actually want to stay at. That knowledge is trapped in old text threads and disappearing stories. SideQuestr is where it lives — your group's pocket playbook. BUILT FOR "WHAT ARE WE DOING TONIGHT" Someone floats the question at 7pm. Forty minutes of debating later, you're still on the couch. SideQuestr collapses that into three taps — see what friends are up to, vote, commit, go. THE CORE • A friend-first map. Your city populated by your crew's favorite places. Every pin shows who dropped it. • Live events happening right now. Shows, pop-ups, markets, nightlife — all tagged with a LIVE badge. • Private uploads for your inner circle. Drop a pin as private and only your close friends see it. The speakeasy, the hidden beach, the quiet coffee shop. Your secrets stay yours. • See who's visited. Every spot shows the friend who dropped it and who's been since. "Jake went last week and loved it" beats any 4.3-star rating. • Commit and go. One tap locks in the plan. No more vague "maybe we'll end up there." • Find your people in seconds. Instagram-style contacts matching — no username gymnastics. WHO IT'S FOR Not travel influencers. Not foodies with tripod setups. SideQuestr is for you and your 3-6 closest friends, the group text that's been going for years. Find or create a spot and share it with your friends on SideQuestr - your friends playbook.
