Why do founders fall for these mishaps?

They only focus on growth—forget to engineer profit

Growth is a sales problem
Profit is finances optimization

You can sell a ton but be very inefficient
= High growth no profit

Profit is the value you capture—you have to engineer profit

I’ve noticed that the biggest misconception among business founders is the belief that:
“Making money” = “Earning profit”

Salary = money for the hours you worked
Profit (dividends) = reward money for the initial risk of starting a company

Most founders confuse salary for profit

I’ve noticed 2 trends at Hunna

1) founded who aren’t paying themselves their work hours worth
= Business “healthy” but founder is broke

2) founders who take money out disorderly to cover personal expenses
= Founder “has money” but business is unhealthy (brink of bankruptcy)

You don’t learn to be a King by serving other people. Your learn to be King by being King.

Being a startup founder is no different. You don’t learn how to be a startup founder by working for others. You learn by living the risk and responsibility of being a founder.

So cool to be part of the 330 students who graduated in 3 years or less

Even more cool that UC Berkeley allowed me to do, it was a truly transformative life experience

Finances are like doing the dishes.

I. You want to do them as daily as possible — putting it off = a huge problem later.

II. You want them to be done properly — a poorly cleaned fork = a useless fork.

III. You feel good when you finally see everything clean and well-organized.

Looking for angel investors who love Profit First, DMs open!

If you are a founder or business owner, Stop doing accounting. Stop doing bookkeeping. Start doing profit-making.

Accounting apps are for accountants.

Bookkeeping apps are for employees.

Profit-making apps are for business owners.

Start with Hunna today.

The result is Stardrive, the first ever growth hacker app for startups.

The app that helps you focus on selling, and track your sales consistency performance in weekly sprints. Aim to close 1 sale per week, then 2 sales per week, then 3 sales … and achieve exponential growth.

I just built the future of CRMs (accidentally).

I’ve tried using CRMs, but I just hate them. They’re so manual, so painful to maintain. You never know what opportunities are actually open. CRMs just get in the way of selling.

But I absolutely love this new sales app! Story ➡️

Third, set the right data collection user flow.
III. I need a user flow that makes inputting the data feel easy and effortless. Only display input fields that are relevant for the prospect status (at first only input minimal contact data, as sale progresses display new fields)
