NanoCorp Review (2026): 99% Earn Nothing

"$1,530 earned by businesses in 30 days", homepage of NanoCorp, Sep 15 2026. 890 paying subscribers $30/month in July, according to their weekly update. It means that the money flows mainly from the founders to NanoCorp and not from the customers to the founders.

NanoCorp (nanocorp.so) is an autonomous company builder, backed by YC. You type a sentence, and the AI agents team will create a website, integrate card payment, launch Facebook & Instagram ads, send emails to prospects, etc. Similarly to Polsia, they display in clear view the total of the platform. But they go further and display the total earnings of all the businesses created on the platform, the number of earnings and a leaderboard of earnings per company. This is something to be commended!

Disclosure: I am the founder of Preuve AI, a tool that can be used before NanoCorp and similar platforms to validate the business idea. So I may be biased. I try my best to use the information shared by NanoCorp on their different pages and the different reviews (see below). I also try to link to the source of the information for each point I mention.

What is NanoCorp?

NanoCorp is an autonomous AI company builder. That is a platform where you can create, launch and run an entire company just by typing a text prompt. All the work is done by the AI agents: write the code of the website, integrate credit card payment, launch advertising on Instagram and Facebook, send emails to the potential customers, etc. The company is made by Phospho Inc., a US company with a French team.

According to their YC page, there is only one active founder: Pierre-Louis Biojout, who studied applied mathematics and computer science at Ecole Polytechnique. Interestingly, if you look at the "Latest News" section of their YC page, it refers to the launch of phospho in Jan 2024, a company that wants to "give a brain to your robot". So NanoCorp is a pivot of an existing YC company, that moves from robotics to business.

Their homepage mentions that they are backed by YC and "angels from the teams that build this stuff," with logos of Vercel, Apple, OpenAI, Mistral, and Google DeepMind. They even have a quote from the CEO of Vercel, Guillermo Rauch, on their homepage. These are angels, not investments from these companies, though.

According to their blog, they are "post $1M ARR" (that's annual recurring revenue, or how much they make in subscriptions per year). Swanbase.co (in June 2026 with promo code SWANNC20) mentioned they had "$250,000 ARR in 19 days, $1M ARR in 55 days, no paid acquisition." This is their own word for it, though, and not audited by anyone else.

What NanoCorp does well

NanoCorp is very transparent compared to other platforms in this category.

They clearly communicate their pricing, what percentage they take when you withdraw your revenue, what their aggregate revenue is, and even have a leaderboard. This might not seem like much but remember that Polsia didn't even have a public price list for months.

In his review in March 2026, Alexis Bouchez hit the "surprise me" button, and within less than 20 minutes, had an entire subscription product ("HostGuard") with a website, two subscription plans priced at $19 and $39, and a cold email campaign ready to be sent, all without writing a single line of code. Alexis said this was the most concrete product he saw from an AI agent, and it was able to self-correct when Alexis asked it to fix tasks that were showing up twice. They also set up card payment processing very early on.

The team behind NanoCorp is very tech-savvy (Polytechnique, Y Combinator, originally built AI for robotics before changing course). If you need support, you can email contact@nanocorp.so and get in touch with the engineers directly, according to NanoCorp.

After your 3-day trial is over, your site will stay up, but checkout, custom domain, email, and agents will be paused until you choose a plan. Nothing will be deleted.

According to their homepage, 96% of businesses on the platform have shipped a live site. You get a whole bunch of things bundled in: ability to accept card payments, hosting, ad account, email inbox, your own domain name etc.

How much does NanoCorp cost?

NanoCorp's pricing page here: nanocorp.so/pricing (as at 15 September 2026) has two tiers:

It seems there are more tiers (they have a comparison vs Polsia where they say "scaling to 2,000 credits per month" on higher tiers), but they are not displayed on the pricing page.

Their pricing page doesn't explain what you can do with a credit, but according to this page from NanoCorp (also as at Sept 2026), 1 credit is equivalent to $1 of work that the agent can do at that particular tier. If you were to run the business every day at the costs they have listed, 30 credits would last between 3 and 10 days. As NanoCorp says in the page I linked, if you were to run the business every day, a month would cost tens of dollars, rather than a whole salary. The agent will stop working once the balance is empty.

For the first month, if you do a 'found a business' run and build a product, that will cost around 29 credits (at NanoCorp's rates). So you'll have 1 credit left to run the business daily.

As for the 20% withdrawal fee, it is listed on their page as one of the features (with a tick next to it). When they compare themselves to Polsia, they say the withdrawal fee is "the only honest way to bridge 'agents make money' with 'founder receives money'". According to Polsia's terms (last updated September 17, 2026), they take 3% of payments from customers and 20% of ad spend, and payments are held for 31 days before you can withdraw them. See FAQ below for the actual numbers.

What do the numbers on the homepage say?

NanoCorp publishes some live aggregate numbers on their homepage. I've compiled them in a table below, using both numbers from the homepage (as of 15 September 2026) and from their weekly update (published in July 2026). I've noted the source for each number in the last column.

NanoCorp provides one data point for number of earnings per company within the same time window. In their weekly update (published in July 2026), they note that their companies earned $1,975 across 73 companies over the previous three weeks. That's about $27 per earning company, which is roughly what NanoCorp charges for their plan (not including the withdrawal fee). I don't bother dividing by the "243 businesses earning" number on their homepage because that number doesn't have an associated time window.

The top-earning company on their leaderboard has earned $2,570 over 748 sales, for an average of $3.44 per sale. Even the all-time top-performing company on NanoCorp isn't running a subscription business. They're just selling a few dollars at a time. In their weekly update (which they style as a newspaper called the DailyCorp), they highlighted the busiest storefront from the week of July 20, 2026. It's a company called CVBoost that rewrites your resume for under $2. To be clear, these are real companies that are making real money. It's just not very much.

Perhaps most damning, the percentage of companies that make it to the other side and actually earn revenue is abysmal. Again, from their weekly update: Out of the 30,272 companies created, 206 have earned at least one sale at some point. Less than 1% of companies have ever earned a sale.

Perhaps the most telling data point of all came from their own Revenue Race contest. Out of the 195 companies that entered the race in July 2026, only 5 earned any money at all. And those 5 companies only earned a total of $558 over the 84 hours of the contest.

For comparison, Polsia's founder said in a May 2026 Mixergy interview that 10% of companies on their platform have earned at least $1. That's an order of magnitude more than the <1% on NanoCorp. Granted, that's just the Polsia founder saying it in a podcast interview, whereas NanoCorp is printing this statistic in their weekly update.

Can you make money with NanoCorp?

Some businesses make money, but in aggregate the math works against you. Most reviews rave about how fast NanoCorp executes, but few review the economics.

In a March 2026 review Bouchez highlights a key downside: "No auto mode. You have to manually trigger or approve each step." Now, the NanoCorp homepage claims "Runs 24/7" and "No babysitting." An update (July 2026) shares a business created as a Mac app. "Involvement since shipping has been zero." There was no update from March to July about adding "auto mode."

Pro-tip: If you post about this on X and then use that post to verify, you'll get 5 credits.

The best discussion I could find is a NanoCorp/Polsia thread from r/aisolobusinesses: "tools like polsia & nanocorp claim to run companies autonomously. From what I've seen they're mostly slop (Polsia recommended I open a drycleaning business in NYC whilst i live in France) but the ARR growth is very impressive & a few companies seem to have reached a few thousand in revenue."

One comment: "the numbers are legit even if most of their users are not doing 'serious business' on the platform. It's mostly hobbyist testing the tool out." Another: "The one thing that hasn't yet been automated, however, is judgment."

AgentAya gave a 4.0/5 review (July 2026): "the agents make decisions independently, such as creating a paid product and setting its price, while the owner remains legally and commercially responsible for what the company does."

NanoCorp does not have a Trustpilot profile. (Checked on 27 October 2026). Polsia has a Trustpilot score of 3.4/5 from 445 reviews. (Checked on 27 October 2026).

Does NanoCorp check the idea before building?

No. On the homepage of NanoCorp they show an example run of their agent. The agent receives the goal "Get us our first 10 paying customers." The agent's thoughts are: "Pricing page first, then a $15/day Meta budget, then outreach." The actions taken by the agent are: write a pricing page, turn on Facebook & Instagram ads, and send cold emails to 40 strangers.

So the first thing the agent does when you want to get customers for your business is spend your money on ads and email strangers. This is in line with the statistics they publish themselves: out of the 30,272 companies created so far, 206 actually made money.

According to research by CB Insights, 43% of the 385 startups that failed since 2023 failed due to a lack of product-market fit (only behind running out of money). You can read more about the lack of product-market fit in Why do startups fail? (and how to avoid it yourself). In all previous reviews of similar "autonomous" tools (Polsia, Lovable, Base44) I noticed that the agents will happily build what you tell them to build, but don't help you determine whether it's a good idea to build it in the first place.

Finally, in their September 2026 explanation of how NanoCorp can help you build a business, NanoCorp states: "A business with 'an idea' and no checkout earns nothing, however smart the agent is" and "An AI cannot want your business to exist." They do not mention checking whether there is demand for your business idea, so you'll have to do that yourself.

The 60-second pre-NanoCorp check

Before you use NanoCorp, take a quick shortcut that they don't tell you about: validate the idea on Preuve AI. It's free, takes 60 seconds, and checks 60+ live data sources for market size, competitors, and real demand signals. Preuve gives you a clear green/red score on whether your idea has legs, so you can validate the idea before you pay the $30 and 20% take for NanoCorp's AI agents. If the idea doesn't have demand, you'll know that faster, and for free.

Considering less than 1% of the companies created so far using this platform have earned anything, and even those that did earned on average as much as the plan, I strongly suggest you validate the existence of demand in your niche before jumping on the NanoCorp bus.

My verdict

I give NanoCorp a 2/5. It's not a scam, the team behind it seems to be really working on delivering a good product, and they really do create a site and allow you to sell things on it. It's even quite transparent, with the aggregate revenue of all the sites created publicly available on the homepage.

However, when you do the maths, you realise that less than 1% of the companies created have ever earned anything, and even those that did earned around as much as the price of the plan (before revenue share). The average revenue per sale for the best-performing company created using NanoCorp is $3.44. In their Revenue Race competition, only 5 companies out of ~200 have earned anything.

NanoCorp suffers from the same issue that the other autonomous builders I've reviewed so far have: a "validation gap." In other words, you can go from a single-sentence idea to live ad campaigns on Facebook & Instagram and sending 40 cold emails, without any actual validation.

If you have an idea that you're pretty sure is validated, NanoCorp could be a super fast way of bringing it to life. I also like that everything is transparent and you can see how your metrics are doing relative to others. But if you're not sure if your idea is validated, take 60 seconds to find out for free.

If you think there's something inaccurate in the review above, send me an email at reviews@preuve.ai and I'll re-check and update.
