Pushing a new update for our onboarding to be fully a chat interface!

I really like it; let's see if the UX is great for our new users!

I want to have a chat interface from A to Z.

2 new tools that I can't live without:

1 - @herdrdev terminal. My journey was Mac terminal, then tmux, then iTerm, and now herdr. It just feels right to manage agents. Big productivity boost.

I am back on youtube! lol.

First time watching an ATP 250 match. Impressive in so many ways, but mainly the speed of the ball that you can't experience on TV.

Summertime again, time to rest or improve the product.

Our conversion rate is dropping.

Hard to convince someone to choose their new bookkeeping software during the holidays.

Luckily we have some partnership coming up :)!

morning time working with the small dev (@bernardo) team after coffee + croissant!

Claude is extending a third time their Fable 5 access included in the Claude Code subscription... no demand, I guess!

I am not the only one who does not use it anymore because it is extremely unstable and nerfed!

Celebrating small wins is important:

Who said improving the product isn't working (better onboarding, cleaner interface, simpler is better)?

Churn rate:
- Jan: 14%
- March: 12%
- May: 8%
- July: 5%

Celebrating small wins is important:

Who said marketing isn't working (Ads + SEO + Webinar)?

MRR growth:
- April: 23%
- May: 38%
- June: 52%

Well, Fable 5 is unusable... switching back to Opus 4.8.

I feel super manipulated; as soon as a competitor has a better model, I will leave Claude.

Time for open source to shine too!

Adding Stripe reconciliation to cashflowy .ai with a Stripe App!

Now you get Stripe fees directly in your bank transactions and ready for your accounting!

decided to create our own internal cashflowy AI with @tanstarter AI.

It's so easy to add tools and functions. I am also using the AI gateway from @vercel.

I love that I can add any graph and React component in the chat.

1 - tanstart AI
2 - AI gateway

Finally trying HERMES. Let's see if it is really useful ?

Any suggestion on how to use it and what for ?

My first simple, fully open-source Chrome extension.

🛑 stop sharing your MRR
✅ but start sharing your actual "Pay"

github .com/Cashflowyai/safe-pay-stripe

⭐ Add some star if you like it :)

I am working more than ever because of AI...

I thought AI would free my time, but it is the opposite. I just build and fix more!

But yes, productivity output is like 20X.

People think AI will do their job, but AI will just enable you to do more.

Expectations are just rising:

After 1 year of being a dad, I finally had the courage to put my @oura ring back on, and after 1 month or so, I got my first triple crown!!

readiness 88 👑
sleep 87 👑
activity 85 👑

Feels good!

My learning is that we need to be patient and there is a time for everything in life.

getting healthier, I guess. :)

1/6 Customer support is king. We got our first new paying user from our updated free trial flow (no credit card required).

What happened yesterday:

1️⃣ User signed up (no card)
2️⃣ Connected their bank
3️⃣ Booked a meeting with our bookkeeper to ask questions and build trust

team team team!!!! 🙂

@PostHog is much better than I thought.

I can finally understand my users like a pro (at least that’s what it feels like!).

Their new AI feature is great, too.

Main advantage: we can have one tool for marketing analytics and product analytics.

I am still surprised about money.

Money's value is so different for everyone:

💹 investor
💼 employee
🚀 founder
💍 your wife
🧒 your son

But still, is it the same thing?

I guess it is a tool, and everyone uses tools differently and more or less efficiently.
