Raj Sheth's CRM drove 30,000 website visits a month, converted 1,000 into trial signups, and turned about 100 into paying customers — all without a sales team. Circle grew to $19M ARR almost entirely through product-led growth. Every time a DocSend user shared a document or a SurveyMonkey user sent a survey, the product introduced itself to new potential customers. That's PLG in action.

These episodes feature founders who built self-serve growth engines that actually work. You'll hear how Pendo maintained over 10,000 free users alongside 3,000 paying customers, using the free tier as a pipeline into paid plans. How Read AI improved retention from 5 percent to 81 percent by stacking AI features that kept users coming back daily. How the viral loops were designed, tested, and refined over months of experimentation.

The conversations go deep on the mechanics that matter: which features to gate behind paid plans, when to introduce pricing in the user journey, and how to track the signals that predict conversion. Founders share the onboarding experiments that moved the needle and the activation metrics that told them whether a new user would convert or churn.

Bilal Aijazi, Polly

How Freemium SaaS Grew to Millions of Users With 20 People

Bilal Aijazi is the co-founder of Polly, an engagement platform that brings polls, surveys, and feedback workflows into the tools teams already use like Slack, Teams, and Zoom. In 2015, Bilal was working at a consumer messaging company, watching apps like WeChat evolve from simple chat tools into full-blown platforms. He figured the same shift would happen at work. So he and his co-founder Samir started experimenting with simple solutions to collect feedback. Their first attempt was an email-based tool, but engagement was terrible. People just treated it like another survey to avoid. Then Slack opened their API. And Bilal noticed people on Twitter asking for Slack polls. So the founders quickly ported their product over, becoming one of the very first Slack apps ever built. But the installation process was clunky. Five manual steps that required copying and pasting tokens between different screens. Yet 80% of people still completed the setup. So they were clearly providing something people wanted. Then one day someone posted Polly on Product Hunt and they went viral overnight. They were getting thousands of new signups every month and struggling to keep the servers running. Yet they had zero revenue. Their first paying customer spent $8 a month for a fantasy football league. Then came the real challenge of building a freemium SaaS - figuring out who would actually pay. Most freemium SaaS users just wanted to do something casual with polls like pick lunch spots. But through hundreds of conversations, they found where the real money was. They focused on company all-hands, sales kickoffs, and other high-stakes meetings where feedback actually mattered. Just when things clicked, Slack threw a spanner in the works. Polly had built a workflow feature for automating feedback. They were signing five-figure deals. Six months later, Slack launched their own solution. The founders had to make a choice. Stay on Slack and hope for the best, or take a massive risk and rebuild everything for multiple platforms. They expanded to Teams, Zoom, Google Meet, and embedded directly into presentations. Rebuilding their entire infrastructure was a huge undertaking, but they had no choice. Today, Polly is one of the most successful freemium SaaS products in the collaboration space, serving millions of monthly active users and generating multiple seven figures in ARR with just 20 people.

Frequently Asked Questions

What is product-led growth in SaaS?+

Product-led growth means the product itself drives acquisition, activation, and expansion without relying on a sales team. Raj Sheth built his CRM on pure PLG: 30,000 website visits turned into 1,000 trial signups and roughly 100 paid customers each month with about a 10 percent conversion rate. Circle grew to $19M ARR almost entirely through product-led growth. SurveyMonkey and DocSend both grew virally because every time a user shared a survey or document, it introduced the product to new potential customers.

Should I use freemium or a free trial for my SaaS?+

Pendo combined both: they maintained over 10,000 free users alongside 3,000 paying customers, using the free tier as a funnel into paid. Raj Sheth's CRM ran a freemium model that consistently converted 10 percent of trial signups to paid. DocSend's free usage went viral among startup founders, and the product spread organically to enterprise accounts. The choice depends on your product's time-to-value: if users need days to see results, a time-limited trial creates urgency; if value is immediate, freemium builds a larger top-of-funnel.

How do you measure product-led growth?+

Raj Sheth tracked his full PLG funnel: 30K visits to 1K trials to 100 paid, monitoring each conversion point. Circle measured expansion revenue as the key metric, growing from $8M to $19M ARR largely through existing customers upgrading. Read AI tracked retention as their north star, watching it climb from 5 percent to 81 percent as they stacked AI features. The metrics that matter most: activation rate, time-to-value, free-to-paid conversion, and net revenue retention from expansion.

Can you combine product-led growth with a sales team?+

Todd Olson at Pendo built the PLG engine first, then layered on enterprise sales when large accounts started self-serving into the product. DocSend saw CISOs signing up with personal Gmail accounts, which signaled enterprise demand they could route to a sales team. Adam Gavish started with a self-serve motion and added sales to close six-figure deals once larger prospects showed up. The hybrid approach works best when PLG generates product-qualified leads and sales accelerates the bigger accounts that need procurement and security review.
