Ten years. Twenty startups.

# 28 startup lessons learned by sweat and tears

[John Rush](https://x.com/johnrushx) failed for ten years across twenty-plus startups before building a holdco with almost a million users. He wrote down the 28 things he wishes someone had told him before his first one. Here is the full list, summarized.

01

## Validate first

He wasted a decade building things nobody needed. Incubators and VCs felt like validation; only paying users are.

02

## Kill your ego

It is not about you. Your taste doesn't matter; the user's expectations do. Build what they want, not what you want.

03

## Don't chase investors

Chase users and investors chase you. His VC interest peaked exactly when he stopped caring about it.

04

## Never hire managers

Until PMF, only hire doers. Plenty of people can manage; very few can get things done barehanded.

05

## The landing page is the least important thing

Template, one hour of edits, one page, obvious signup button. Optimize conversion only once traffic is consistent.

06

## Hire only fullstack devs

Nothing is less productive than a team of specialists on an early product. One fullstack dev builds the whole thing.

07

## Go global from day 1

If the product is good it works globally; if it is bad it fails locally too. Same effort, 100x the upside.

08

## Do SEO from day 2

His biggest regret after 14 years of skipping it. Ten low-competition keywords on the homepage, one blog post a week.

09

## Sell features before building them

He DMs 10 to 20 users daily about ideas and only builds what resonates. No audience? Ask on HN, Reddit, or X replies.

10

## Hire only people you would want to hug

If you would not hug them, some animal-level dislike is there, and it surfaces as conflict eventually. Startups take years; pick people accordingly.

11

## Invest in your startups and your friends

Of ~70 friends' startups he could have backed, 3 became unicorns. Since 2022 everything goes into his products, friends, and network.

12

## Post on X daily

His primary source of connections and growth. The only regret is not starting earlier.

13

## Don't partner with corporates

Big promises, millions of users, and every single time: nothing. They burn your time and focus and bring no one.

14

## Don't get distracted by hype

Crypto cost him 1.5 years and several friendships. Stay on your mission when the gold rush passes through.

15

## Build B2B, not consumer

Consumer apps are a lottery with a monetization problem even when they win. He spent 4 years there and regrets it.

16

## Kill bad projects within a year

Some ideas cannot be pivoted and some teams cannot gel. Dragging it out for years is the real loss.

17

## Skip tech conferences

Money, energy, and time for a room of corporate employees on a loyalty perk. The makers aren't there.

18

## Scrum is a scam

If a team needs daily nagging like kindergarten, it fails anyway. Grownups sync over chat on goals and plans.

19

## Outsource nothing until PMF

External hands give the product no love and no creativity. It is just another assignment in their boring job.

20

## Bootstrap

He raised 10+ times; each round was a 3 to 9 month project of meetings and distraction. He could have afforded not to.

21

## It may take a decade

He postponed family and kids for an exit that took far longer than planned. Do not put life on hold for the startup.

22

## No free tier

Free signups became his KPIs and his feedback loop, and the product became a perfect free product. Paid-only until validated.

23

## Don't be the cheapest

The $5 customer is never happy, never refers, and leaves in 4 months. The $50 customer gives real feedback and becomes a fan.

24

## You will fail. Plan for it

Almost every startup fails, so fail faster: get to the second iteration, then the third, until something works.

25

## Use boilerplates

He burned years and VC money rebuilding sidebars, dashboards and payment flows out of pride. Your product isn't special there.

26

## Spend time with family and friends

He missed every best friend's wedding. Giving life 10% of your time costs your startup practically nothing.

27

## Build for an audience you love

He had no love for corporates, consumers, or devs. Switching to indie founders multiplied his joy by 100x.

28

## Write every single day

A teacher's red pen silenced him for 15 years; a spellchecker brought it back. Writing daily is how the audience compounds.

## Lesson 12 was  
post every single day.

Viraloop is how founders actually do it: on-brand short-form content, generated and published to TikTok, Reels and Shorts daily, on autopilot.
