Mycel runs the work your service business sells - clients, deliverables, approvals, invoices. Each job runs in a disposable sandbox that never holds a credential, and nothing reaches a client until you approve it. From $299/mo, or self-host free.
If you run client work, you are the last pair of eyes on everything. Every report, every update, every deck. That is what caps how many clients you can carry. It gets worse as you grow.
Three ways out, and you have priced all of them. Hire at $45k plus six weeks of ramp. Keep doing it yourself every evening. Or turn the work down.
A chat window drafts fine. It also forgets what you corrected the moment the tab closes. Month six costs you what week one did.
Mycel is built the other way round.
Every job gets its own machine. A sandbox boots, does the work, and is destroyed. The agent never holds your keys.
Then the checks run on the output. A summary says four findings. The table lists five. The draft is held and made to say why, and you never see it.
It writes against what that client received last month. An open item does not vanish between deliveries. Edit before you approve and both versions are kept. The diff is what it learns from.
It runs on its own clock. Five timers are live in the demo now. Chasing what is owed. Resuming work that stalled. Keeping the business findable. Nobody starts them in the morning.
Nothing reaches a client without your sign-off.
I am in the comments all day. What is the piece of client work you would never let a machine touch?
The correction loop is the piece I'd test first. I run a few clients whose reports don't look anything alike. Does a fix on one of them change how the others get drafted?
Congrats on the launch bro! You've worked so hard on Mycel!! I love using it and i can't wait for it to fully run al of my work, when do you think it's gonna be possible :))
It's really cool how you can fix the draft once and let Mycel learn from that process. I love the attention to the actual client experience.
The approval layer and learning from the past edits is the part that really caught me. For client work, AI that remembers how you actually deliver feels way more useful than another chat window. Really interesting approach. Congrats on the launch!
Hey what kind of deliverables can it be is it necessarily a file at the end? Or can it be publishing something ?
In your video i noticed ADS, does it run ads too?
Nice one. When it drafts something for a client, how much of it is usually right first time? how much of the work is reading and fixing versus just signing off.
Honestly, I had to read through this a couple of times to fully understand what Mycel does, but once I got the core idea, I found it really interesting.
One of my colleagues in my extended team actually works closely with clients and handles a lot of this kind of work, so I can already think of someone I’d recommend Mycel to. I feel this could genuinely save him a lot of time, especially with the repetitive client work and workflows he has to deal with.
Congrats once again and best wishes to the team. 🫡
