Simplero

Calvin Corelli's journey to Simplero began in 2008 during a personal crisis. After working as a freelance developer and consultant for a decade, a major client outsourced his work to India—the same week he and his wife bought a house (at triple the expected cost due to a mortgage technicality), had their second child, and faced severe financial stress. Everything he tried to make money failed. Desperate, he sat down one night and asked himself fundamental questions: What do I love? What energizes me? He realized he'd been unconsciously manufacturing financial stress to avoid looking inward. His breakthrough came from combining two sides of himself—his spiritual interests in presence and service (inspired by work with a coach and spiritual teacher) with his pragmatic programming skills. He even changed his legal name from Lars Holger Pinds to Calvin, inspired by Calvin Coolidge's quote on persistence.

With clarity on his purpose—serving others and helping entrepreneurs—Calvin decided to teach courses on entrepreneurship and mindset. In 2008, he needed software to deliver online courses but found nothing he liked, so he built his own in Ruby on Rails. Designed as multi-tenant from the start, Simplero initially combined email marketing, course delivery, and basic automation. He was dogmatic about the architecture because he sensed it would be valuable for others, even though he had no customers at first.

For the first year (2009-2010), Calvin gave Simplero away for free while financing development through his own online courses. By September 2010, he started charging. Early growth came organically from his tight-knit Danish community. He held monthly showcases at his home where 100+ people would attend—part educational, part promotional—to see the product in action and connect. Word-of-mouth spread quickly in Denmark. By December 2012, he was making just under $10,000 MRR and could support himself. His big break into the US market came in 2012 when he invested $2,000 in Marie Forleo's B School course, not for the content but for access to her 5,000+ person Facebook community. He answered technical questions in the group and offered B School members three free months of Simplero, which brought in approximately 25 customers—his first real US foothold.

Calvin learned hard lessons about marketing. He tried Google AdWords multiple times, spending tens of thousands of dollars with expert agencies—zero results. He created an affiliate program that cost 20% of his bottom line and delivered almost nothing except one highly productive affiliate in Norway. He experimented with paid ads and content marketing; neither moved the needle.

What actually worked: personal service, authenticity, and word-of-mouth. He started a weekly newsletter with three segments: a personal essay on life lessons and spirituality, Simplero product updates, and three random internet links he'd found that week—intentionally unrelated to online courses. Customers told him they stayed with Simplero partly because they loved his newsletter. He hosted events in Denmark that let people see him as a real person. The through-line was intimacy and realness—letting customers see who he was, treating them as individuals, and serving them deeply.

Simplero bootstrapped profitably to $2 million ARR by May 2016 (approximately $166,667 MRR). Growth remained slow and steady month-over-month—"whether or not I try to, it just kept growing." Calvin attributes this to relentless focus on product quality, customer service, and what he calls "being very real with people." He stopped pushing himself to be an educator or marketer and recommitted fully to Simplero during a period when he'd stepped back and nearly gave it up. Two things kept him going: his responsibility to customers whose livelihoods depended on the platform, and finally aligning his work with his deepest purpose—service, presence, and authenticity. Today, Simplero remains bootstrapped, profitable, and proud, with no outside investment, selling a niche-focused platform for online educators and coaches who want simplicity and personal touch over flashy marketing.
