Who Is Danny Postma?

Danny Postma is the Dutch entrepreneur behind HeadshotPro, an AI-powered headshot generator that reached an astounding $300,000 in monthly recurring revenue (MRR) within a year of its launch.

But Danny’s story isn’t just about one successful product. It’s a journey of failures, mindset shifts, strategic pivots, and ultimately, building a portfolio of AI businesses that collectively generate millions annually, all while documenting the process publicly.

The Early Days: From Marketing Consultant to Indie Hacker

Danny Postma didn’t start as a programmer. In fact, his first business was born out of necessity rather than technical expertise.

Landingfolio was Danny’s first major project, launched in 2015 when he was just 21 years old. At the time, he was working as a freelance conversion optimization specialist and struggled to create effective landing page designs for his clients. His solution? Build a design gallery showcasing the coolest landing page designs on the internet.

There was just one problem: Danny didn’t know how to code.

Rather than letting this stop him, he built Landingfolio using WordPress, a platform that required no programming knowledge. The site still exists today and attracts thousands of visitors monthly.

The lesson: You don’t need to be a developer to start. What matters is identifying a problem and finding a way to solve it with the tools available to you.

However, Landingfolio had one major limitation: it was difficult to monetize. This realization pushed Danny to move on to other projects, setting the stage for his first real breakthrough.

Headlime: The First Big Win (and a Seven-Figure Exit)

Before HeadshotPro, there was Headlime, the product that would prove Danny’s ability to spot trends and execute quickly.

Headlime started as a simple idea. Danny had written an interactive book featuring 200 headline formulas. Realizing this could be turned into software, he created a simple copy spinner that automatically replaced variables in headlines.

But then something serendipitous happened.

Around the same time Danny was building Headlime, OpenAI released GPT-3. Danny reached out directly to Greg Brockman, OpenAI’s CTO, and gained access as part of the first batch of users.

This timing was critical. Danny experimented with letting GPT-3 write headline templates and was “astounded by its ability to generate copy”. He became one of the first people to implement GPT-3 in a production environment, alongside Copy.ai and a handful of others.

The Numbers

Headlime grew rapidly:

  • $1,000 MRR in December 2020

  • $20,000 MRR by February 2021

  • Sold for seven figures (reportedly $1 million) in early 2021 to Jasper.ai (formerly Conversion.ai)

The acquisition was a life-changing moment. In just eight months, Danny had built and sold a SaaS business for seven figures, all while documenting the journey publicly.

The lesson: Timing matters. Being an early mover on a major technology shift (like GPT-3) can create massive opportunities. But you also need the product foundation to capitalize on it.

The AI Pivot: How a Stock Photo Idea Became HeadshotPro

After selling Headlime, Danny continued building. But the path to HeadshotPro wasn’t linear, it involved several pivots based on market feedback.

ProfilePicture.AI: The First Hit

When Stable Diffusion launched in September 2022, Danny saw an opportunity. His initial idea was to create a stock photo website called Stock AI, but concerns about legal issues from major image companies like Getty Images made him reconsider.

Instead, he pivoted to **ProfilePicture.AI -** a service that generated AI profile pictures from user photos. He built and launched it in just 30 hours, beating competitors to market.

The product exploded on Twitter, generating six-figure sales in its first week.

The Decline and Second Pivot

However, as the initial excitement faded, sales began to decline. This is where many founders would give up. Instead, Danny listened to what the market was telling him.

He noticed that users were specifically asking for professional headshots, not just fun profile pictures. So he pivoted again, focusing on creating high-quality, realistic headshots using AI.

Deep Agency and HeadshotPro

In a bold move, Danny launched two products simultaneously: Deep Agency (an AI modeling agency) and HeadshotPro.

While Deep Agency generated press attention, it didn’t translate into sales. HeadshotPro, on the other hand, was an instant hit.

The lesson: Launch multiple experiments and let the market decide. Deep Agency got the hype, but HeadshotPro got the revenue. Danny followed the signal.

How HeadshotPro Makes Money

HeadshotPro operates on a straightforward one-time payment model with no subscriptions:

  • Basic: $29 for 40 headshots

  • Standard: $39 for 100 headshots

  • Premium: $59 for 200 headshots

There’s no free trial, but the company offers refunds for unsatisfied customers, a smart trust-building tactic.

What Makes HeadshotPro Different?

According to Danny, the primary differentiator is quality. While competitors rely on open-source models like Stable Diffusion and DreamBooth, HeadshotPro uses dozens of custom models in a massive backend pipeline.

“We’ve been working for a full year now on our own custom models. We’re getting really close to consistently generating AI photos that are indistinguishable from real photos,” Danny explained in an interview.

The company also focuses exclusively on professional headshots rather than expanding into dating photos or avatars, a strategic decision to maintain focus and quality.

Build in Public: Danny’s Transparency Advantage

One of the most distinctive aspects of Danny’s journey is his commitment to building in public.

Building in public means sharing your journey transparently the wins, the failures, the revenue numbers, the struggles. Danny has been doing this since his Headlime days.

In a podcast interview, Danny discussed both the pros and cons of this approach. The benefits include:

  • Accountability: Sharing goals publicly creates pressure to follow through.

  • Community building: People become invested in your journey.

  • Marketing: Your story becomes content that attracts users and customers.

  • Network effects: Other builders share your work, expanding your reach.

The Pieter Levels Connection

Danny’s relationship with fellow indie hacker Pieter Levels (founder of NomadList and PhotoAI) exemplifies the power of community. When Danny launched HeadshotPro, Pieter repeatedly retweeted his posts, helping him grow significantly on Twitter.

This mutual support isn’t coincidental, it’s a feature of the building-in-public ecosystem. By being transparent and helpful, Danny attracted the attention and support of established players.

The Audience Question

Danny currently has over 104,000 followers on X (formerly Twitter). But his audience didn’t come first, it followed his success.

As one analysis noted: “Some of the most popular indie hackers with a big Twitter following… Their following is due to their success and the way they use the platform”. Danny built products first, and the audience came because people wanted to learn from his success.

The Solo Founder Identity

For years, Danny operated as a solopreneur. His portfolio of AI projects collectively generated over $300,000 MRR “without employees”.

But as HeadshotPro grew, Danny faced a critical decision: sell the business, continue as a solopreneur, or build a team.

Overcoming the Fear of Hiring

Danny admitted in an interview that transitioning from solopreneur to team builder was a significant challenge:

“One of the primary challenges I faced was the fear of hiring. Initially, I was hesitant to scale the team because of the uncertainties involved in managing people”.

He started with contractors and part-time people, creating a safety net while learning team management. Today, Danny has a small team of “incredible smart and dedicated people” who handle things he could never do alone.

“Looking back, I should have started a team way earlier. It’s also way less lonely and much more fun to share your wins together”.

Current Status: Did Danny Postma Sell HeadshotPro?

No, Danny Postma has not sold HeadshotPro. Unlike Headlime, which was acquired within eight months, HeadshotPro remains under Danny’s ownership through his holding company Postcrafts.

He is, however, in the process of selling some of his smaller AI products to focus entirely on HeadshotPro.

SEO Strategy: How HeadshotPro Dominates Google

Given the search terms people use to find Danny’s story, it’s worth examining how HeadshotPro achieved such strong organic visibility.

The Two-Pronged SEO Approach

Danny’s SEO strategy, broken down by Indie Hackers, combines two complementary approaches:

1. Programmatic SEO

  • Generating hundreds of pages targeting location-based keywords

  • Examples: “professional headshots san francisco,” “professional headshots boston”

  • This allowed HeadshotPro to rank for long-tail keywords with less competition

2. Traditional Blog Content

  • Writing blog posts targeting specific keywords

  • Building authority over time through consistent content

The Results

Within three months of launch, HeadshotPro was ranking in the top 10 for “professional headshots” a keyword with:

  • 21,000 monthly searches

  • Keyword difficulty of 23

The site ranks for over 1,000 keywords, with many generating significant traffic.

The Keyword Research Process

Danny has shared his keyword research methodology for those looking to replicate his success:

  1. Find a keyword with:

    • Keyword difficulty < 20 (needs fewer than 10 backlinks to rank)

    • Volume > 500 searches monthly

    • Multiple child keywords (long-tail variations)

  2. Research for 1-2 days before committing

  3. Build the product around the keyword

  4. Optimize the main keyword across the site

  5. Create sub-pages for child keywords

  6. Offer both free and paid plans to capture traffic

Danny notes that SEO takes time: about 3 months for initial traffic and 6+ months for significant growth.

Product Hunt and Backlinks: The Growth Accelerator

Product Hunt has been a recurring tool in Danny’s growth strategy, not just for users, but for backlinks.

The Backlink Strategy

When Danny launches on Product Hunt, his primary goal isn’t user acquisition, it’s the domain authority boost.

Here’s why: When you launch on Product Hunt, you get a backlink from a high-authority domain. But because other sites repost and share Product Hunt links, you often get backlinks from 10 to 50 different sites.

“Even coming in last is a win,” Danny notes. The backlinks alone can be enough to rank #1 for long-tail keywords.

The Headlime Product Hunt Launch

When Danny launched Headlime V2 on Product Hunt (December 8, 2022), it was a huge success that accelerated the product’s growth from $1K to $20K MRR.

Lessons from Danny Postma’s Journey

Danny Postma’s story offers actionable lessons for anyone building products:

1. Start Before You’re Ready

Danny built Landingfolio without knowing how to code. He launched ProfilePicture.AI in 30 hours. Speed matters more than perfection.

2. Ride Technology Waves

Being an early adopter of GPT-3 gave Danny a massive advantage with Headlime. Being early on Stable Diffusion did the same for HeadshotPro.

3. Pivot Based on Data

When ProfilePicture.AI sales declined, Danny didn’t abandon AI photography, he pivoted to headshots based on what users wanted.

4. Build in Public

Transparency creates trust, attracts supporters like Pieter Levels, and generates organic marketing through your story.

5. SEO Is a Growth Engine

Danny’s SEO strategy (programmatic pages + quality content) drives consistent traffic without ongoing ad spend.

6. Hire Before You’re Ready

“I should have started a team way earlier,” Danny admits. Don’t let the fear of hiring cap your growth.

7. Focus Wins

HeadshotPro focuses exclusively on professional headshots while competitors chase horizontal expansion. This focus enables superior quality.
