What a startup needs from a virtual office

• A place the team actually shows up to, so a remote startup still has hallway conversations.
• Something that looks credible when customers, candidates and investors join.
• Pricing that starts small and grows per person.
• No IT project. Founders do not have time to run one.

Startup virtual office software at a glance

1. Katmai: best for startups that sell, hire and raise online

Katmai is a photorealistic 3D office in the browser, with live video of each person and spatial audio. A startup team works there all day, so the quick question across the room still happens when everyone is remote. When a customer, a candidate or an investor joins by link, with no account and no download, they walk into an office that looks like a company. Katmai's team configures your office and adds your users after a demo, and one plan includes every feature. See how it works for a virtual sales floor and for remote onboarding.

Pros: real faces in a credible office; guests join with nothing to install; setup done for you.

Cons: demo-led, so you start with a call rather than a self-serve signup; built for teams of roughly 10 or more; photoreal rendering wants reasonably modern machines (system requirements published).

Best for: startups of about 10 or more people that spend the day talking to customers, candidates and each other.

2. Roam: best all-in-one

Roam (ro.am) shows your company as a map of offices and rooms, and you click into a room to talk. One plan bundles the office with drop-in meetings, an all-hands theater, team chat, a meeting scheduler, an AI note taker, a screen recorder and an AI assistant, for $19.50 per active member per month, billed monthly, with a 14-day free trial. For a startup, the appeal is consolidation: fewer tools to buy and connect. More: Katmai vs Roam and Roam alternatives.

Pros: one bill instead of several tools; you pay only for members active that month; a structured layout.

Cons: no free plan; no avatar movement or proximity audio; Roam's pricing page says the price rises to $20.88 in 2027.

Best for: startups that want to put chat, scheduling and recording into one tool early.

3. Kumospace: best free start for a founding team

Kumospace is a spatial office with a modern look: proximity audio and video, rooms with doors for private conversations, and desktop and mobile apps. The free plan covers up to 5 registered members, and Business starts at $16 per user per month with a 14-day free trial. More: Katmai vs Kumospace.

Pros: free for a founding team of five; polished visuals; desktop and mobile apps.

Cons: avatars rather than faces; the free plan stops at 5 members.

Best for: founding teams that want to start free and upgrade as they hire.

4. SoWork: best budget avatar office

SoWork is a 2.5D virtual office with avatars and proximity conversations, Slack-style team chat, calendar integration, and AI summaries, transcripts and action items on its Premium plan. The free plan covers up to 10 members with a 30-minute limit per meeting, and there is a 7-day free trial of the paid features. More: SoWork alternatives.

Pros: free for up to 10 members; AI meeting features on Premium; low cost per member.

Cons: a game-style isometric look; 30-minute meeting cap on the free plan.

Best for: early teams of 10 or fewer where cost comes first.

5. Gather: best customizable avatar office

Gather is the original avatar office: a pixel-art map where video opens when you walk up to someone. Gather 2.0 adds persistent chat, meetings and AI meeting notes, and maps are highly customizable. There is no free plan; Gather offers a 30-day free trial. More: Katmai vs Gather and Gather alternatives.

Pros: deep map customization; a 30-day trial; a well-known product.

Cons: no free plan; a game-style look in front of customers and investors.

Best for: startups with a playful culture that want to design their own space.

6. WorkAdventure: best open source

WorkAdventure is the open-source option: a pixel-art 2D office with proximity video that you can run on your own servers or use as a hosted service. The hosted free plan covers up to 10 users, and Business starts at €8 per user per month.

Pros: full control of data and hosting; self-hostable; very customizable maps.

Cons: self-hosting needs someone to run it; a game-style look.
