This young Spaniard multiplied by 10 his turnover in 3 months with a startup that allows you to create and sell your own Instagram filters

That Instagram feeds a lot of influencers is nothing new, but that everyone who wants can earn money thanks to the popular social network maybe it is.

And no, neither Instagram nor brands are going to start paying you to upload photos in the latest fashion bar, but you can make others pay to use your filters.

That's the idea Jacinto Fleta had to create Check my Presets, a website that allows you to earn extra money by creating filters (or presets) that other people buy to use in their photos.

A preset is a file that applies to images and causes them to be automatically edited in the style that the creator of that preset has set.

"We are moving towards a world where millions of people will make a living on the internet independently. No bosses, but also no employees. Self-sufficient. Indie creators. People who live off what they generate on the internet. It is called 'Passion economy'. I prefer to call it 'internet freelancers'", says Fleta to Business Insider Spain.

The Valencian, who worked marketing his own company Flamingueo (an ecommerce of trendy products and decoration), took advantage of the quarantine to learn to program. "I studied 4-5 hours every day for 3 months and then it took a month to develop the first version." He started trying to sell the product within Flamingueo's online store and, after thousands of sales in a short time, he realized the size of the market.

From there, he decided to devote himself full-time to Check my Presets and delegate his tasks to Flamingueo.

Fleta wanted to build Check my Presets with total transparency by sharing the process-obstacles included-and the results through their social networks. "At first I thought no one would be interested but I'm surprised with the interaction. It has allowed me to meet amazing people, get feedback from engineers better than me and, quite unexpectedly, get several customers," he says.

In these months, turnover has skyrocketed. During the first month (July) it was 150 euros, in August 945 euros and in September 1560 euros. In October it has had a slight drop. "I'm far from break even, as that's gross billing and from there Check my Presets stays between 20% and 30%. The idea is to grow without haste, but without pause, " Fleta points out.

According to the creator, the goal is to be one more platform where these creators can earn money and be, in the future, "the number 1" in this type of graphic resource.

Part of the strategy is not to invest in advertising

"The decision not to spend on ads was made in my previous company. At Flamingueo we invested a lot in ads and one day we decided to radically lower the budget, " says Fleta. These are their reasons for it:

  • When you make ads you tend to think that selling more Is Making Better Ads and that, if you sell little, it is the fault of the campaigns. This makes the product take a second place, when it is really in charge of meeting the needs of users.
  • Growing with the focus on the product is much slower, but more solid. If you sell more, you're doing better.
  • By putting the product in the center you stop relying on creativity when doing marketing campaigns and start thinking about how to improve to sell more.
  • Ads, especially Facebook and Google ads, were a bargain 5 years ago when there were many users and few companies investing. Today, prices are higher and making them profitable requires a lot of creativity and time. Being such a small startup I have to prioritize and decide what not to do.
  • Many companies that invest in Facebook ads have ROAS (Return On Advertising Spend) of 2 to 5 globally. That means that for every euro invested they charge from 2 to 5 euros. That is, 20% to 50% of VAT invoicing. The problem is that it is very difficult to stop doing it because when you stop the billing collapses and psychologically it is hard. Sometimes, it's a drug.
  • In a startup resources are limited and I can think of many better things to spend money on.
  • Many times we see experts on facebook ads sharing amazing results. The problem is that many times they are sharing their best campaign and, if you take stock of the other 50 campaigns they have active, globally the result is not so surprising.
  • Making ads to scale before you know if you have product market fit is, in my opinion, throwing the money away. You will bill a lot without profit and then users will stop using/buying you.

Fleta nuances that she does not consider that investing in advertising does not make sense. "It is very likely that a balance between product and ads is the best and depends a lot on the type of company and its timing. But it's not the company I want to build," he says.
