Hi! I'm Harshil, founder of Dream Launch Studios. Today I want to share the incredible journey of Joshua, the founder of postal.app, a content creation tool that's helping creators generate engaging social media content. Joshua's story is a perfect example of how building in public, starting with side projects, and focusing on user feedback can lead to a successful SaaS business.
Joshua's journey into the tech world started with a simple side project called "Wakeup Call" - a website that visualized your remaining life expectancy based on your age and country. The project went viral on Reddit, bringing 1,500 unique visitors overnight and teaching Joshua a crucial lesson: content can drive massive traffic to your projects.
This Reddit success led Joshua to discover Twitter's built-in public community, where he started sharing his journey and connecting with other builders. "I couldn't really share this excitement because I had no builder friends in my circle," Joshua recalls. "So I created my Twitter account the same day and started posting."
This was the beginning of Joshua's content creation journey - a skill that would later become central to his business.
After meeting his co-founders on Twitter, Joshua and his team identified a common pain point: content creation takes up too much time. Joshua had been doing freelance content creation work, writing Reddit posts and tweets for clients, and his workload had exploded.
"I got so many freelance clients that my personal workload kind of exploded," Joshua explains. "So I came up with a super hacky way to automate some parts of that content creation workflow."
The team decided to productize this workflow and launched postal.app three months ago. Initially, they targeted multiple platforms (Reddit, LinkedIn, and X) simultaneously, but quickly realized this broad approach was overwhelming and hard to market.
The key insight came from user behavior analysis. Joshua and his team used PostHog to track how users interacted with the platform and discovered that all users were primarily using it for X (Twitter).
"We saw that all of our users were using it only for X and they came from X," Joshua says. "So X was the thing they were most interested in."
This data-driven decision led to a strategic pivot - focusing exclusively on X before expanding to other platforms. This focus made marketing much easier and allowed the team to perfect their product for one platform before scaling.
Joshua had been saving for three years while working a corporate job, building up 24 months of runway. But the decision to go full-time came from observing user behavior.
"I watched almost every screen recording in PostHog just to see how people interact with the app," Joshua explains. "There was something that made me go, damn, they actually spend hours in the app to create content."
Seeing users spend hours daily creating content was the strong signal Joshua needed. "If we find just more people like that person, we have got like 20 selected users that use the app almost every single day to create content. That was the signal I needed."
Joshua has built a strong following on Twitter by sharing his journey authentically. His content strategy focuses on:

Joshua's vision extends beyond just building a successful SaaS. He plans to relocate to Thailand (his mother's homeland) to stretch his runway and reconnect with his roots.
"I want to get back to my roots. I'm half Thai and I would love to live in Thailand, learn the language again," Joshua shares. "I want to sell everything except for a few martial arts clothes, my Mac and my surfboard."
His goal is to build 10 hours a day while pursuing his passions for martial arts and surfing - the perfect blend of work and lifestyle.
