Colin Hirdman: LinkedIn Growth Hacks, AI and Ethical Automation (Ethical Automation)

On this episode of the Scouting For Growth podcast, Sabine VdL talks to Colin Hirdman, the antidote to automated mediocrity. As a lifelong entrepreneur and co-founder of Monkey Island Ventures, he has spent two decades scaling SaaS tools, digital agencies, and now Rainmaker – a ‘white-glove’ service that ethically automates LinkedIn outreach to turn connections into revenue. Colin discusses Rainmaker’s ‘Authentic Engine’ framework: 10-30% connection rates, campaigns tailored to micro-audiences, and why human-driven strategies still dominate AI in B2B growth. As well as why he targets 25 people/day — and how even solo founders can replicate this, the ‘criminal justice grad’ who turned entrepreneur, accidently and sold his first startup days after college, and LinkedIn’s automation guardrails: What’s ‘ethical’ vs. what gets you banned. KEY TAKEAWAYS          I’ve done a lot of growth hacking through email and LinkedIn, but I got better results through LinkedIn and ended up building out a software and process for myself. Rainmaker was born through me making it available to other businesses. But, you don’t need me or rainmaker to do any of the things we discuss on this podcast, you can do it manually. You have to be authentic on LinkedIn, both as yourself as well as the brands you represent. You should also have an educational mindset – no one wants to be sold to on LinkedIn, but almost everyone is willing to be educated – and an experimentation mindset, trying different features and functions of LinkedIn, stack the things that work and set aside the things that don’t. Understand the pains an barriers that you prospects are trying to overcome and know what it is that you can teach them. Growth hacks: LinkedIn Events – if you have a direct competitor, industry or organisation putting on a LinkedIn Event that your business solves for, if you attend that event you can see everyone else who attended that event and create a prospects list. Use people who are big in your area as proxies – use people’s open connections to see all first connections to her, second connections to you and is in your area, and begin connecting to them Building out your first connections is critical. I reach out to 15 people per day Monday-Friday during normal working hours. That gives you 500 people per month, which is below LinkedIn’s limits. Typically, you’ll get a 20% connection rate. Within 30 days of sending an invite, and they haven’t connected, withdraw the invite. It’s good hygiene, but after 3 weeks you can reach out to them again. Everything you do after that only gets better and has stronger possibilities as your audience grows. BEST MOMENTS ‘There are lots of opportunities to engage with your prospects on LinkedIn in ways that are valuable for relationship building and set you up as a thought leader.’ ‘People undervalue the value of being a first connection, when you’re a first connection you can see all kids of information about them, direct message them, and use other features and functions to engage with them.’ ‘I typically build my audience through Sales Navigator – a tool within LinkedIn that allows you to hone in on audiences..’ ‘If you’re using automation that is in any way inauthentic, it won’t work; you wouldn’t immediately set up a meeting with someone you just met. I wish people would stop; it’s lazy.’ ABOUT THE GUEST Colin Hirdman is a lifelong entrepreneur, startup advocate, and visionary behind Rainmaker, a platform revolutionizing LinkedIn’s growth strategies through its "Authentic Engine."
