Partner for a proposed product
When you refer a product developed from your own proposal, you earn 40% while each paid plan remains active.
Commission is earned only when a referred user is billed for a paid plan. Free plans, free trials, and months affected by refunds, chargebacks, or non-payment are not eligible.
The exact conditions for each rate are set out in the Mumu Labo Partner Program terms.
Why high payout
Why the payout can be this high
Recurring rather than one-off, and direct rather than through a network — so the person doing the referring is rewarded for longer, and better.
Recurring while paid plans stay active
Not a one-off bounty: as long as the user you referred stays on a paid plan, the commission keeps coming, and the rate never tapers. Every referral you add builds the monthly base.
Direct partnership, no network margin
You partner directly with the operator, so no affiliate network takes a cut. There is no setup fee and no fixed cost — purely performance-based. That is what makes the rate affordable to offer.
You get to pick the niche that sells
You are not limited to promoting what already exists. Propose a product that would be easy to recommend in your niche, and if it looks promising I plan and build it. Your instinct for what sells turns straight into revenue.
Products built for Japanese practice, law, and language
These products cover exactly what overseas apps tend to miss for the Japanese market, and I handle planning, development, operation, and support myself — so you can recommend them with confidence.
For you
Who this suits
It rewards people who already refer, and who have a niche of their own.
- You are looking for high-payout offers that recur rather than pay once
- You are good at recommending subscription, SaaS, or product-led tools
- You can reach an audience through a blog, social media, YouTube, or a newsletter
- You want your videos and articles to become an ongoing income base
- You want to strengthen YouTube monetisation and description-link affiliates
- You have a feel for what sells in a particular field
- You find network offers too low-paying and too one-off
- You want to help shape the product you recommend, not just promote it
For YouTubers & creators
For video creators and YouTubers
A review video is an evergreen asset that keeps getting watched after publication. Add commission that accrues while referred users stay on a paid plan, and one video can become an ongoing income base — a strong fit for video creators.
A free account for reviewing
If you are making a video or a review, you get a free account to try the features for real and record your screen. Recommending something you have actually used makes for a far more convincing video.
A media kit
Logos, screenshots, demo data, and the key selling points, packaged together — so thumbnails and walkthrough videos are much less work (terms, article 9).
Tracked by your description link (?ref=)
Registrations through your link are the first attribution method, including same-device cookie carry-over within 30 days. See the terms for the full attribution order.
Help with Japan’s paid-promotion disclosure rules
Japanese law requires a clear “PR” disclosure both inside the video and in the description. I share a guide on how to word it under the Premiums and Representations Act and the stealth-marketing rules, so you can promote with confidence (terms, article 8).
Retail, resale, e-commerce operations, back office and bookkeeping — if your audience has those problems, you can recommend a tool that solves them and treat it as an asset that keeps paying. Start with an application

FAQ
Frequently asked questions
- Q. What is the commission rate, and why is it this high?
- A. On the subscription revenue paid by the users you refer: 20% as standard, 30% for users who pre-register before launch through your referral link, and 40% when you refer a product developed from your own proposal. All three accrue monthly while the paid plan remains active. Confirmed quarter-end balances of ¥5,000 or more are paid by the end of the following month. Because the partnership is direct, no affiliate network margin is deducted.
- Q. How long does the commission keep paying?
- A. Commission accrues for as long as the user you referred stays on a paid plan. The rate does not taper over time, so subscription referrals can accumulate into an ongoing base.
- Q. Do I need to join an affiliate network, or pay anything up front?
- A. No. You partner directly with the operator, so no network takes a cut. There is no setup fee and no fixed cost — purely performance-based. Bank transfer fees are borne by the affiliate.
- Q. When does a commission start?
- A. From the month a referred user finishes their free trial and their first payment on a paid plan is confirmed. Free plans and free-trial periods are not eligible.
- Q. What is the payout threshold and schedule?
- A. Accounts close quarterly. If your confirmed balance at the end of a quarter is ¥5,000 or more, it is transferred to the bank account you nominate by the end of the following month. Below ¥5,000 it carries over to the next quarter. Bank transfer fees are borne by the affiliate and may be deducted from the payout.
- Q. What if a referred user cancels and then subscribes again?
- A. Both the attribution and the rate carry over unchanged (a user who qualified for the 30% early rate stays at 30%). Commission resumes from the month paid billing restarts; no commission accrues for the period when there was no billing.
- Q. What kinds of products can I recommend?
- A. Propose an idea for something that would be easy to recommend in your field. If it looks promising, I plan and build it, and you promote it. Your sense of what sells in a niche turns straight into revenue. Custom development enquiries are welcome too.
- Q. Can I promote on YouTube or in review videos?
- A. Yes — it is a strong fit. A review video can keep being watched after publication, and commission continues while referred users stay on a paid plan. As with a blog or social post, you refer through the link in your description.
- Q. Is this “passive income” that pays while I do nothing?
- A. It is not a guarantee of income for no work. You earn only once you have made the article or video and put it in front of your audience. A published review can keep being read or watched, and commission continues while referred users stay on a paid plan, so the work can remain an ongoing asset.
- Q. Do I get an account to review with?
- A. Yes. If you are making a video or a review, you get a free review account so you can try the features for real and record your screen. You also get a media kit with logos, screenshots, and demo data (terms, article 9).
- Q. Can a link in a YouTube description be tracked?
- A. Yes. Registrations through your link are the first attribution method, including same-device cookie carry-over within 30 days. If the program ends, remove or disable the link as required by the terms.
- Q. How should I disclose paid promotion in a video?
- A. Under Japan’s Premiums and Representations Act and its stealth-marketing rules, you must clearly indicate that the content is advertising or promotion — for example “PR” — both inside the video and in the description. I share a guide on how to word it (terms, article 8).
