Thunkable

Arun Saigel had spent years as a lead Android developer at Quizlet and worked at Khan Academy and Google—elite tech pedigree for someone in their mid-twenties. But he noticed a massive market gap: millions of people had app ideas but couldn't code. Existing solutions either required expensive outsourcing or still demanded coding knowledge (just in JavaScript instead of Java). In late 2015, inspired by his research at MIT, he decided to build Thunkable, a platform simple enough for a non-developer to use yet powerful enough to actually build real apps.

Thunkable launched in early 2016 and quickly gained traction through organic adoption. The platform was so intuitive and genuinely useful that millions of people signed up. One particularly striking example: when Yemen's civil war knocked out the power grid in 2015, a young Yemeni man who'd never coded found Thunkable, built an app to help 1,000 families manage their solar panel tilting, and solved a problem Arun himself had never anticipated. This story exemplified the power of democratized app development—enabling problem-solving in places and contexts no startup would ever target directly.

Thunkable's initial users were exactly who Arun targeted: individuals with no alternatives, people who simply needed to build an app and had no other way to do it. Rather than chasing enterprise contracts or upmarket SMBs, the company followed the Dropbox playbook—dominate consumer/individual usage first, then watch those users bring the tool into their companies. By the time of this interview, Thunkable had broken a 100,000-unit sales mark and millions of users on the platform.

The product-led approach worked spectacularly. By offering a free tier for non-commercial use (like the Yemen case), Thunkable could serve humanity while building a massive user base at minimal acquisition cost. The planned monetization strategy was elegantly simple: free for builders solving personal problems; paid features (analytics, in-app purchases, app store optimization) for entrepreneurs trying to build businesses. Arun had raised $3.3M to sustain the team of 10 and was about to "turn on the paywall" to measure conversion. The big open question: could low-ARP, high-volume SMB monetization actually work at scale, or would churn kill them like it had Constant Contact?

As of the interview, Thunkable was on the verge of a critical inflection point. The platform had proven product-market fit with millions of users and massive network effects—7 million people on the platform, with users building apps for use cases the founders never imagined. Revenue was still coming primarily from enterprise integrations (flat-fee contracts, typically $50-$10,000+ annually), but the real test awaited: turning on premium features for SMBs and watching churn rates. Arun's goal was ambitious—capture 90% of the apps on the Play Store and iTunes—starting with the underserved individual and small business segment, just as Dropbox had done.
