Lobi Space is not a law firm and does not give legal advice. We prepare and file documents at your direction.

You answer a few questions. A person on our team checks the name, prepares the Articles and files them with the state. No forms to decipher at midnight.
Premium includes your first year. On Starter and Pro, add the service for $95 a year. Anything served on your company is scanned the day it lands and you hear about it the same day.
Premium includes three months of Business Mailbox Pro, a $90 value, at our staffed office in Pilsen, with your suite number, mail scanning and pickup.
Your filing, your agent, your mail and your meeting room all sit in one building with one bill. Call us and a person picks up.
One question per screen. Name, owners, what the business does. Ten minutes, and you can stop and come back.
We confirm your name is available, prepare the Articles and submit them to the Secretary of State at your direction.
Stamped Articles, your EIN, your agent appointment and a checklist of what to do next. Open the bank account and get to work.

I got Google verified in a week with the Lobi address after two failed attempts elsewhere. Mail gets scanned before lunch.
We run the whole company from here: mailbox downstairs, meeting room upstairs. One bill, one building, no WeWork upsell calls.
Registered agent plus notary in the same place saved me a courier run every month. Staff actually answer the phone.
The virtual office gives us a staffed Chicago address, mail handling and a room when clients visit.
Mail forwarding to Arizona every Friday like clockwork. I have not missed an IRS notice since switching.
Started on the mailbox plan, moved into a private office six months later. No renegotiation drama.
Walk-in notary saved my closing twice. They stamped and scanned everything in under ten minutes.
Same-day scans mean I see checks before the bank does. On-demand pickup is worth it alone.
The meeting rooms are properly kitted out and reception makes client days easy.
Registered agent for both entities plus one address on every filing. Renewal reminders actually arrive.
