How can I get clients for my agency in a developing country without using any paid tools?
Yeah, tackle the situation. To be abundantly clear, you can do anything without money, but it's just a lot more difficult. It's like taking a 5‑lb dumbbell curl and turning it into a 100‑lb curl — possible, but it takes a lot of time, effort, and training. If you have even $20 to put toward this, your life gets tremendously easier. My recommendation is not to start a business with literally zero; if you don't have money, get a job or something similar and run that side‑by‑side with your entrepreneurial effort. Necessity is the mother of invention, and people have found creative ways to bootstrap, but I prefer to just get a job. I've been there — I'd bring tea bags from home to Starbucks for hot water, and my business partner would bring cheap cream cheese and expired bagels to make low‑cost meals. It's not a good spot. It's much better to get a job for a couple of months, save a little money, and then try entrepreneurship afterward. To answer the spirit of your question, I would do cold DMs on social media platforms — LinkedIn, X.com, Instagram, and so on. Unlike email, where you need to pay for mailboxes, lead enrichment, and tools (around $97‑$40 a month), social media platforms are free; you only pay with your attention, and the algorithms give you equal access regardless of wealth or fame. You need good copywriting principles and attention‑grabbing techniques. For example, you could say, 'Hey Pete, I can save you $10,000 a month in the next 60 seconds. I'll give you everything for free at the end of this, whether or not you want to work together.' That kind of hook gets attention. Aim for 20‑40 DMs a day across these platforms. If you do that consistently for a month, you'll reach about 1,200 people. With good copy, good offers, and decent Loom videos, you'll absolutely drive results.
