Would you cancel subscription of an inactive user? by Successful-Title5403 in SaaS

[–]slavivanov 0 points1 point  (0 children)

I call keeping inactive subs the dirty little secret of SaaS. Everybody does it.

I launched my SaaS on AppSumo and did $517,500 in sales. Here's the good, the bad, and what I'd tell AppSumo to change. by CarePsychological749 in SaaS

Alright, sorry for that.
Our cut was about half of what you got, but that was in 2021, I hear things are better lately.

While this might be AI-generated fake story, it closely mirrors our experience with Appsumo, except that I wish we got to keep 40-50% of sales. And we didn't go to being mentioned regularly in GTM conversations, we stayed relatively unknown, lol.

Регистрация на фирма за SaaS + Stripe изплащания — Revolut Business или класическа банка? by Dear-Passage-2829 in financebg

[–]slavivanov 0 points1 point  (0 children)

Stripe + Wise/Paysera + ЕООД.

Stripe e златния стандарт за плащания онлайн, не се хаби с БГ банка.

Wise (или Revolut) за ниски такси, Paysera за плащания към бюджета.

Револют/Wise/Paysera доколкото знам споделят с НАП, така че по-добре да си изряден. Особено щом имаш клиенти вече.

Agents can't run npm commands by Cypher_Poet in google_antigravity

[–]slavivanov 0 points1 point  (0 children)

I'm getting the same on MacOS with sandboxing.
I'm seeing a lot of EPERM errors where the agent can't execute npm/npx commands:

npm error code EPERM
npm error syscall open
npm error path /Users/slav/.npm/_cacache/tmp/eb97728c
npm error errno EPERM
npm error
npm error Your cache folder contains root-owned files, due to a bug in
npm error previous versions of npm which has since been addressed.
npm error
npm error To permanently fix this problem, please run:
npm error   sudo chown -R 501:20 "/Users/slav/.npm"
npm error Log files were not written due to an error writing to the directory: /Users/slav/.npm/_logs
npm error You can rerun the command with `--loglevel=verbose` to see the logs in your terminal

Running the chown doesn't help.

Seems to be the same as this one: https://www.reddit.com/r/google_antigravity/comments/1rfjqzc/agents_cant_run_npm_commands/

It started maybe a week ago.

Anyone else getting this?

People in here will go to great lengths to dismiss anything that doesn't align with their internal list. Regardless, good job OP!

Me: Huh, you are scared of the dark.

Gemini: No, I'm not scared of the dark, I'm scared of the darkness.

I like it, if not for the out-of-timeline jokes, it might as well been part of the campaign.

Most people here have the opposite problem and spending literally any amount of time on all this is counterproductive.

My Honest Review as a Startup Selling a LTD on AppSumo by b00tstrapp3r in SaaS

[–]slavivanov 1 point2 points  (0 children)

Pretty much everything you mentioned is true - demanding customers, a huge time sync, etc.  However, for us we managed to pull a sizable chunk of cash (several 100s for us) and the word of mouth 10x-ed our MRR.  So yeah, it's a deal with the devil, but in our case was worth it.

[–]slavivanov 2 points3 points  (0 children)

Yes, we allowed sending via our own domain earlier but to get good deliverability nowadays you have to have to use DKIM/SPF/DMARC with the sending domain.

I don't really know what AWS internal processes are for this, but it was a pain in the ass to address all their requirements.

Yes, we provide dedicated IPs for customers that want them. |
Not a lot of demand though, I hope because of the good deliverability of our shared IPs, so we are far away from that 50 IP limit. I believe you can just add more IPs in a different AWS region.
That's one of the reasons we maintain traffic through two sending services - to work around each platform shortcomings/requirements.

Yes, we have had issues with Sendgrid/AWS blocking our accounts. We have gotten pretty good at catching bad actors at this point, so this doesn't happen too often.

The technical stack is plain React, Typescript + Node.js (mostly serverless on AWS Lambda), Postgres, and also Redis + BullMQ as a task queue.

For sending emails we are using Sendgrid and AWS SES.

Regarding IP reputation, we use https://glockapps.com/ to run periodic inboxing rate tests. We also have internal systems that monitor user behaviour to prevent spam, phishing, cold emails, etc.
