I Sold My $800K/Year Agency to Go All-In on My SaaS

Yousef's story starts inside an agency that was making serious money but draining him. He and Arno built The Scale Lab after careers around tech and sales, including time at Google and AWS for Yousef. The agency did cold email, cold calling, and LinkedIn lead generation. It grew to roughly $750K to $800K a year, close to a million, but the work came with the classic agency problems: repeated delivery, staff churn, client churn, cash flow pressure, and a business that took more energy as it scaled.

ScaleList came from the pain they kept solving manually. As an agency, they were always building contact lists for clients, extracting leads, and then finding emails and phone numbers. Existing tools solved pieces of the workflow, but not the whole thing in the way they needed. The internal tool helped the agency scale, and people started asking what stack they used. That was the signal: the problem was not just theirs. Even though Yousef and Arno were nontechnical sales founders, they knew the problem deeply and searched for technical help, eventually finding Charlie through an Indie Hackers post.

The transition was not instant. For about a year to a year and three months, the SaaS sat around $1K to $1.5K MRR while the agency paid the bills. Yousef says that is one of the traps for agency founders: if the SaaS is treated like a side project, it cannot be judged on a short timeline. They split responsibilities because Arno had to keep the agency revenue coming in, while Yousef led the SaaS push. Eventually they sold the agency in September so they could recover 100% of their time for ScaleList.

The distribution breakthrough was YouTube. Outbound, which had worked as a service for clients, barely worked for ScaleList. YouTube had low competition for exact intent keywords like how to export leads from LinkedIn Sales Navigator. The best performing video was not a polished production. It was a simple Loom style video, recorded with a bad mic, that got 10,000 views. Yousef explains the process: keyword research, study what exists, keep videos short, show the exact steps, and stay consistent. YouTube now drives about 50% of acquisition, with roughly one paid customer per 250 to 300 views based on their economics.

Then the business hit platform risk. ScaleList was growing around 15% month over month and had reached about $22.5K MRR when LinkedIn sent a cease and desist. Since the positioning and top videos were built around exporting LinkedIn leads, the team had to comply, remove LinkedIn focused marketing, and reposition fast. Fundraising from TinySeed, completed before the LinkedIn issue, gave them capital and mentorship through the pivot. They moved toward being a data provider for emails, phone numbers, API use cases, and MCP access for AI tools. Yousef's lesson is to think harder about the market, the business model, the exit path, platform risk, and whether you can stay excited about the space for years.
