15-Year Overnight Success: How Amber Bootstrapped a Side Project to an 8-Figure Exit to Philips

What Does It Take to Bootstrap a Side Project Into an 8-Figure Exit?

Amber Vodegel grew up in a Dutch village of 1,200 people. Her father suffered two brain injuries and was hospitalised. Her parents divorced when she was 10. At 30, she moved to London and cut her salary by two thirds to start over in advertising, working her way from junior account manager back to senior strategy director.

In 2009, she started experimenting with apps. Her first two companies taught her hard lessons: don't work with friends, and don't go into business with your partner. Her third attempt, Pregnancy+, she built deliberately to sell. She coded the backend from scratch, hacked the App Store algorithm with emoji tricks, priced it at £4.99 with a free first trimester, and grew it to 12 million downloads without taking a penny of outside capital. In 2017, Philips acquired the company. She still held 98% of the equity. The deal was eight figures.

She stayed at Philips for six years, scaling Pregnancy+ to 150 million users in over 100 countries. She left in 2023. Now she's building 28X, a free, privacy-first women's health app where all data stays on the user's device. No subscriptions, no cloud, no data harvesting.

GUEST BIO

Inside Philips, she scaled Pregnancy+ to over 150 million users across 100+ countries with two million daily active users. She left in 2023 and is now building 28X, a free, privacy-first period tracking and women's health app backed by the Philips Foundation and 40 mission-aligned angel investors.

KEY TAKEAWAYS

1. If you're building to sell, start with the backend. Amber walked away from a profitable company because the code wouldn't survive due diligence. The third time, she built it right

2. You don't need venture capital to exit for eight figures. She bootstrapped for five years, reinvested everything, and kept 98% of the equity at sale.

3. The exit is not the finish line. Amber woke up after an eight-figure sale and felt nothing. Careers are longer than any single company. Plan for what comes after.

The 23mile playbook

• Build to sell from day one. Amber looked at her second company's backend and knew it wouldn't survive due diligence. She started over and built Pregnancy+ with acquisition-ready code from the beginning.

• Keep your equity. No VCs, no angels, no dilution. She reinvested every pound of revenue back into the app for five years. At exit, she held 98% of the shares.

• Hack distribution before you build features. She used emoji characters and the "+" symbol to game App Store keyword matching and rank number one for "Pregnancy Tracker" automatically.

• Price for the 80%, not the 5%. Free for the first 13 weeks (because of miscarriage risk), then £4.99 one-off. No subscriptions. She averaged 15% conversion, with some countries hitting 30-35%.

• Write at a reading age of 9. The article "The relationship between oral health and miscarriage" got no engagement. Rewritten as "I brush my teeth more often in pregnancy?" it transformed.

• Money doesn't bring happiness. She woke up the day after the exit and nothing had changed. Got divorced six months later. There's always someone with a bigger boat.

• Stop watching TV. Her advice for anyone wanting to start a business on the side. Limit TV to one or two nights a week. The time is there if you prioritise it.

Memorable Quotes

"People say money doesn't bring happiness. I can guarantee you it brings zero happiness."

"When we sold the company to Philips, we still had 98% of the shares, which was exceptional."

"I looked at the app and I thought, if I ever sell this company and they look at the backend coding, they're not gonna purchase this. So what I did is start again."

"I said that I would make him CEO because I felt a woman couldn't be above her husband. We got divorced later. Next lesson, do not start companies with your partner."

"The sacrifice you need to make is do not watch TV. There's so much time wasted in watching Netflix. If you want to set up a business, the first thing you do is limit your TV evenings to one or two a week maximum."

"I had to cut my salary by two thirds, if not more. I went back to a starter salary for a junior account manager. And I said, that's okay."

"I would put the kids in bed at seven o'clock and then work. From between seven and eleven, which is another four hours, I would work at least five days a week."

"Everyone with Claude can build an app in seven or eight minutes. But last year there were 85% more apps uploaded to the App Store."

"There's a threshold where it's nice that you don't have to worry about paying for your mortgage. But anything above that, there's not much difference. And there's always someone with a bigger boat."

"I named the app Pregnancy Tracker and then space Smiley. And that meant I had the hard keyword match. So when someone typed in Pregnancy Tracker, we would rank number one automatically."
