Mentor Cruise

Dominic Mon's idea for Mentor Cruise came from lived experience. After completing an apprenticeship in software engineering in Switzerland, he pursued machine learning through Udacity's program—which provided him with a mentor who kept him accountable and motivated. When he finished the course and moved into an internship at a major tech company, he lost that mentor at exactly the moment he needed one most. He was juggling a demanding job, a brutal three-hour daily commute, and the challenge of learning Kotlin for the internship. The realization was clear: mentorship was incredibly valuable, but it was fragile—tied to specific programs or employers. If you changed jobs, schools, or companies, you lost your guide. "If you switch employers, if you switch schools, if you switch from an apprenticeship or an internship, you're essentially losing access to that mentor," Dominic explained. He wanted to build a marketplace where mentorship was decoupled from institutions—a place where anyone learning anything in tech could find someone experienced to guide them through the journey.

Dominic started building in late 2017 while working full-time and enduring that grueling commute. He had no formal understanding of what an MVP was, so he packed his initial feature list with far more than necessary. The implementation took three to four months—an hour or two per day during the commute, plus a few more hours if he stayed up late, and weekend work. The turning point came when he realized he didn't need to build everything himself. He had planned to create a custom appointment scheduler for mentors and mentees to book video calls, but then thought: why reinvent the wheel? Services like Calendly already solved this perfectly. That single decision probably saved him two months of engineering work. Similar shortcuts followed—he stopped planning to build custom chat or task management features and instead used existing tools. These constraints, born from limited free time, actually forced the kind of ruthless prioritization that most founders struggle to achieve.

Before he even launched, Dominic knew the hardest part wouldn't be the code—it would be solving the chicken-and-egg problem of a two-sided marketplace. No mentees want to join a platform with no mentors, and no mentors want to join a platform with no mentees. So he built a simple landing page with just a headline and an email field, then spent a month doing something that didn't scale: reaching out to hundreds of people on Twitter. He sent direct messages to senior engineers, data scientists, and people with decent followings in tech. Most didn't reply. But he was disciplined about it—every message was personal, handwritten, no spam templates. He asked people if they'd be interested in mentoring on his new platform and making some money doing it. Out of hundreds of outreach attempts, about 60 people gave him their email address. He wasn't confident yet, but 60 was enough.

When Mentor Cruise launched, it had about 12 mentors with complete profiles—not a huge number, but enough to feel real. Several of them had Twitter followings, and they tweeted about joining the platform. That initial network effect got the first mentees in the door. But the real growth engine turned out to be organic search. As more mentors joined and people searched for things like "Python mentor" or "machine learning mentor" on Google, Mentor Cruise's listings started appearing. That was incredibly compelling—when someone was actively searching for help with a specific technology, seeing 10 available mentors they could book right now made the conversion natural.

Dominic continued to recruit mentors the old-fashioned way: messaging people he respected and asking if they'd be willing to mentor. The pitch got easier as the platform grew. In the early days, messaging 100 people might yield 10 responses, with 8 of those being "no thanks." But as Mentor Cruise became more established, messaging 10 or 20 carefully selected people became far more effective. People could see the platform was real, that mentees were already using it, and that this could be a meaningful side income.

The biggest surprise came when Dominic decided to reach out to his power users directly. He queried his database for mentees who had been matched for at least six months and spent over $1,000 with the platform. Then he did something radical: he wrote 120 individual, personalized emails to these people, asking about their experience. The response was eye-opening. He had been sending surveys and reading complaints from dissatisfied customers, and he thought that was "talking to users." But when he actually talked to his best customers, he heard stories he'd never heard before.

One mentee was Ryan Wilson, a former professional basketball player in the UK, who used Mentor Cruise to transition into cybersecurity after retirement. Another was a veteran from Afghanistan who was learning full-stack development with the help of multiple mentors from the platform. These stories never showed up in surveys or complaint tickets—they only emerged in real conversations with people who were thriving. It shifted Dominic's perspective on what to optimize for.

The business model is simple: Mentor Cruise takes a 15% commission on each mentor-mentee transaction. Mentors set their own price (typically $0–$50 per week), and users commit to weekly check-ins, though the frequency of calls or chats can vary. They recently launched a "sessions" product for one-off services like portfolio reviews, with a fixed fee instead of a percentage. But the core commission model poses a long-term question: how do you scale revenue when taking a cut of mentor income feels slightly predatory? Dominic is exploring other revenue models, but he's cautious about anything that might discourage mentors from joining or push them to other platforms.

Mentor Cruise is generating $700 per month in MRR—entirely bootstrapped, entirely a side project. Dominic still works full-time remotely for a San Francisco startup (which gives him the flexibility to work on Mentor Cruise nights and weekends), and he's in Zurich, Switzerland. The platform now has 160 mentors across design, engineering (various languages and frameworks), product management, and other tech disciplines. SEO is by far the most effective growth channel—people actively searching for mentors are finding Mentor Cruise at the top of Google results.

His approach to time management is ruthlessly practical. He blocks his day job, then ruthlessly prioritizes what goes into his limited free time. Some evenings might be 30 minutes of focused work; weekends might yield 2–3 hours. He throws away features and ideas that aren't truly important. He doesn't try to do everything; he focuses on the few things that matter most—which right now, beyond product improvements driven by user feedback, is finding and recruiting the best mentors.

Dominic's closing advice to anyone starting a side project or learning something new: "Get someone in the boat with you." Whether it's through Mentor Cruise, Indie Hackers, or your personal network, find a mentor who sticks with you. Mentorship isn't just about the information your mentor shares—though that matters. It's about accountability, perspective, and motivation when the journey gets long.
