I used @tryfirstbase for my biz. Went super-smooth. Highly recommend it.
Thank you for getting the company set up super fast. I think it happened efficiently. The team is there to email if you have questions too. The dashboard accurately displays what is completed and what to expect.
Incredible Service. This was a fast, easy, hassle-free experience, I won't say it matched my expectations, NO, It exceeded my expectations and amazed me. They're the best of the best. So happy that I chose Firstbase and confident I'll make another round for another venture.
Wow, @tryfirstbase is really fantastic. Set up the corp, EIN, registered agent, bank account through/via them and 1.5 months later I'm way more organized than I ever was.
Quick and simple LLC formation. Was done in a few days with minimal paperwork.
Great service! The process is extremely easy!
I hope Firstbase will review this. I am very much satisfied with the service. I had some issues earlier with my application but they resolved them within a day. :D I would recommend their service and appreciate their hard work to make this world a better place for business. :D Cheers.
