Co-Founder · ChatSEO.app
FranceHello! Who are you and what business did you start?
I’m Paul Vengeons, a French SEO consultant and one of the co-founders of ChatSEO.app. I started the business alongside my amazing co-founders, Nicholas Dulait and Léo Leducq.
ChatSEO is an AI-powered SEO assistant. Think of it as a super-smart chatbot that connects directly to your Google Search Console. Instead of just giving you a bunch of confusing charts and numbers like traditional SEO tools, it acts like an expert consultant. It tells you exactly what to create, what to optimize, and what to fix so you can rank better on Google and new AI search engines.
Our target audience is founders, indie hackers, website owners, and agencies. We built this for people who want expert-level SEO but don't want to pay for five different expensive tool subscriptions or hire high-priced consultants. Our positioning is simple: We are the SEO expert who already knows your site. We give you clear, data-driven advice, not just a data dump.
Today, we are completely bootstrapped. We have grown to around €14,000 in Monthly Recurring Revenue (MRR) in just about 3 months (roughly 87 days), and we generated €70,000 in total revenue in our first 5 months. The best part? We did all of this with zero paid ads. It is 100% organic growth.
What's your backstory and how did you come up with the idea?
My journey into SEO started back in 2020. I began as a freelance "try-harder," taking small gigs and learning how search engines worked. Eventually, I leveled up by working at two different SEO agencies in Paris. That was my bootcamp. I built a strong reputation as a freelance SEO consultant and shared everything I knew on my personal website and my Substack newsletter (paulvengeons.substack.com).
The specific idea for ChatSEO actually started with a coaching call.
My future co-founder, Nicholas Dulait, paid me €200 for a consulting session to help with the SEO for his previous startup. A few months later, Nicholas sent me an email. He pitched the idea of building an AI SEO tool together. Because we had already worked together and respected each other, we decided to team up.
We knew we needed a strong technical lead, so after having calls with many developers, we recruited Léo Leducq. Léo had great experience building SaaS products.
As a trio, we aligned on a strict "20/80 vision." We wanted a tool that was simple, clear, and powerful enough to get real results without over-engineering it.
I had noticed a massive problem in the market: traditional SEO tools just dump raw data on you. Busy founders and non-experts struggle to understand what that data means. They don't know what to do first. We wanted ChatSEO to turn that messy data into a simple conversation. You can ask it, "Why did my traffic drop?" or "What are my quick wins this week?" and it gives you a ready-to-use plan.
Take us through the validation and building the first version of the product.
We didn't just build in secret and hope people would buy it. Validation was incredibly tight.
We ran very strict beta phases. In "Wave 1," we let 100 free users into the app. But there was a catch: to use it, they had to get on a feedback call with us. Those calls were pure gold. We learned exactly what confused them, what they loved, and what they actually needed. In "Wave 2," we tested a paywall to see if people would actually open their wallets. They did.
Building the Product and the Tech Stack:
We are a small, focused team, and we move fast. We did not take any VC money.
To build quickly, we relied heavily on AI. We used Claude (Anthropic) extensively for coding and building out features. At the core, our tech integrates with Google Search Console (GSC) and uses conversational AI that is strictly trained on my proven SEO methods.
We focused on actionable outputs over flashy features. A user needs a plan they can use today, not just a nice-looking graph. As we evolved, we iterated fast based on how people were using it. For example, we added a WordPress connection to make applying changes even easier. Users from our early beta phases often tell us they can't believe how much the product has improved in such a short time.
What is your revenue model and pricing?
We keep pricing simple and highly competitive. We operate a standard SaaS subscription model:
-
Starter Plan (€29/month): Great for indie hackers and solo founders.
-
Ranker Plan (€79/month): Geared toward agencies or users with multiple sites.
Because traditional enterprise SEO tools easily cost over €150 to €200 a month, our pricing makes ChatSEO an absolute no-brainer for people who just want clear answers without paying for a massive suite of features they will never use.
This model helped us hit that ~€14k MRR mark rapidly. We have thousands of sites connected, over 400 founders who openly trust us, and strong testimonials from e-commerce owners, consultants, and total beginners who are seeing real traffic growth.
How did you get your first customers?
Our very first customers came directly from my existing audience. Because I had spent years building trust on LinkedIn (@VengeonsP) and my newsletter, I had a warm list of people waiting to see what I built. My consulting clients were also early adopters.
But the real magic happened during the beta phase. By forcing those early 100 users to get on a call with us, we built incredible loyalty. Those beta users loved that we listened to them and fixed their problems. They became our biggest fans and our first paying customers when we launched the paywall.
We also used content funnels and direct outreach, giving qualified prospects free mini-audits to show them the immediate value of the tool.
Since launch, what exactly is your mechanism for acquiring customers? (The 8-Channel Organic Stack)
This is the absolute core of our success. We generated €70k in revenue without spending a single penny on paid ads. Our customer acquisition is a highly disciplined, 8-channel organic system.
Our main secret is rhythm over volume. We don't just spray content randomly. We have fixed weekly routines for each channel. Once set up, it runs like a machine. We also practice heavy recycling. We have about 10 base "playbooks" (core topics or strategies) that we turn into infinite content. If a post performs well, we wait three weeks and post a slightly updated version of it again.
Here is a breakdown of our exact growth channels:
1. LinkedIn (The Awareness Engine)
We post 3 "playbooks" a week per person. We use specific headline hacks (for example, telling people: "Tape chatseo dans Google" / "Type chatseo into Google"). We also use the "value-first + FOMO" method, meaning we post highly valuable info and say, "Comment 'STACK' to get the full guide." This drives massive engagement and leads. My LinkedIn went from 1,500 to 13,500 followers in just 3 months using this.
2. YouTube (The Conversion King)
We publish 1 video a week in both French and English. We are very strict about quality. We use Claude to score our titles, hooks, and thumbnails, and we won't publish unless Claude gives it an 8/10 or higher. The big secret here? YouTube converts 3x better than LinkedIn. People who watch a 10-minute screen-share video trust you way more than someone skimming a 10-second text post.
3. Outbound LinkedIn (The Sniper Approach)
We send 50 personalized messages a day. We use a tool called PhantomBuster combined with ChatSEO. We extract a list of prospects, automatically run a quick audit on their site using our tool, and send them a message with top opportunities to fix their site—along with a direct link to ChatSEO. Because we give upfront value instead of a boring sales pitch, our reply rate is a crazy 10% to 25%.
4. Newsletter / Substack (The Closer)
We send 3 to 4 emails a week. We capture emails from all our other channels and put them into automated sequences using Customer.io. Our signup-to-paid conversion rate from these emails is excellent because we constantly educate the user on how to win at SEO.
5. Twitter / X
Consistent posting, value threads, and engaging with the indie hacker community. It keeps our brand top of mind.
6. SEO Strategy (The Compounding Secret)
We eat our own dog food we use ChatSEO to do our own SEO. We create pages duplicating successful patterns for low-competition keywords (about 2 a week in FR and EN).
Here is a major rule for bootstrapped SaaS: Long-tail SEO compounds. Thousands of small keywords beat chasing huge keywords. If you rank #1 for fifty tiny keywords that bring in highly targeted buyers, you will make more money than trying to fight big companies for one massive keyword that brings zero sales. Thanks to this, we now get over 2,500 monthly brand searches just for the word "chatseo."
7. Free Tools (The Traffic Magnet)
We use Claude Code workflows to build and launch 2 to 4 free "mini SEO tools" a week. These tools target very specific, low-competition keywords. They act as lead magnets, driving free traffic, backlinks, and brand awareness directly to our main app.
8. WhatsApp, Podcasts, Reddit, and Affiliates
We maintain high-touch relationships on WhatsApp with power users. We post value hooks on niche subreddits showing product demos. Finally, we set up an affiliate program that actually pays well (we’ve paid out €600 in a single chunk to promoters), which turns our users into our sales team.
Through building this, what mistakes did you make and what did you learn?
We definitely made mistakes. Early on, we fell into the classic founder trap: we over-spread our efforts. We tried to be everywhere at once without a proper system. It is exhausting. You are much better off picking one or two channels and mastering them before adding more.
Another big mistake is acting only as developers instead of researchers and experimenters. It is easy to just put your head down and code. But you have to step back. We realized we needed to iterate our business model just as fast as our code. When we tweaked our freemium model and adjusted our pricing limits, we saw massive jumps in revenue. You have to balance rapid shipping with polishing the things that actually make money.
What are your biggest "Secrets" for other Indie Hackers reading this?
If you are reading this on mrrstory.com and want to build a profitable SaaS, here is what you need to remember:
-
Discipline + Recycling = Compounding without burnout. Don't wake up every day wondering what to post. Create a system. Repurpose your best stuff. Patient on results, impatient on actions.
-
Dogfood your product. If you build a tool, use it to grow your business. We use ChatSEO for all our content, outreach, and strategy. If it doesn't work for you, it won't work for your customers.
-
Personal branding transfers credibility. Because I spent years giving away my SEO secrets for free, that trust transferred directly to the software when we launched. Give away your secrets. Your execution is your real moat.
-
The 20/80 Focus. Prioritize what moves revenue and usage, not perfection. A simple tool that gets a user a result in 5 minutes is better than a complex tool that takes 5 hours to learn.
Why does ChatSEO work so well in today's market?
SEO is changing fast with the rise of AI and generative search. But founders still want traffic. ChatSEO makes modern SEO accessible and proactive. People prefer one single, conversational tool over fragmented, expensive suites.
Ultimately, our story proves that pure execution beats genius ideas. Organic systems beat paid ads for sustainable, high-quality SaaS growth when you execute them relentlessly.
