How to start a Multi-Vault Navigator for Obsidian business: plan and growth
Obsidian users want to register several vault directories and see them in one explorer instead of switching between completely separate windows.
An owner can start “Multi-Vault Navigator for Obsidian” from a complaint people already posted. The offer, in one line: Browse and search several Obsidian vaults in one window while keeping their sync and privacy separate. It is for Obsidian users. Charge a one-time purchase, and test a price between $10 and $49 a month. Begin in more than one country. Buyers already talk about this in r/ObsidianMD. One thread gathered 130 votes and 52 replies across Sep 14, 2026 – Oct 14, 2026. Use that room to meet the first twenty buyers. Do not export it, and do not republish the posts. The idea, the evidence, and the market estimate on this page are free to read. Two paid prompts finish the job: one drafts the offer, the price, and a ninety-day calendar; the other drafts a month of conversations and proof. One credit unlocks both. A software specification is not on this site. When the company is the product itself, a single link further down opens the founder library.

Who would pay
Obsidian users. Start in more than one country, and charge a one-time purchase, testing a price between $10 and $49 a month.
The thread above is the public complaint this business can learn from. Verbatim quotes are not invented. Further sources, when a later report adds them, stay with the evidence.

The offer, in our words
A plugin/add-on that merges multiple vaults into one navigation and search interface while preserving separate sync and privacy.
Score 2.75, Simmering. Pain, willingness to pay, demand, and the gap in current options drive it. We are not scoring how fast you can code.
Market size
An estimate, built from the bottom up: real customer counts × a realistic price. It shows the size of the prize, not a forecast.
TAM Total addressable
$8.7M
300,000 users · 10% of Obsidian users worldwide (low end of public estimates)
SAM Serviceable
$4.3M
150,000 users · the community plugin directory
SOM Obtainable in 3 years
$87K
3,000 users · 2% of the reachable segment in three years
What that means
3,000 users at $29 = $87K in sales
Medium confidence · estimated Oct 2026
How we estimated this
- Base: 3,000,000 Obsidian users worldwide (low end of public estimates).
- Has the problem: 10% (assume 1 in 10 keep several vaults).
- Revenue per user: $29 one-time ($29 one-time).
- Reachable: 50% (the community plugin directory).
- Three-year capture: 2% of the reachable segment.
TAM is customers with the problem × revenue per customer. SAM is the part a new business can reach. SOM is a cautious three-year share of SAM. The bars use a log scale. A share marked “assume” is our judgment, not a measurement.

Questions
How much money do I need to start?
Enough to talk to buyers and deliver the offer once. A service version can start with a written process and a way to take payment. A software version is a larger bet and is not required to test the price. The band to test is $10–49 a month.
How should I price it?
Test a price between $10 and $49 a month, charged as a one-time purchase. Raise it after three paid pilots, not before the first conversation.
Where do the first customers come from?
r/ObsidianMD is the clue. A related thread gathered 130 votes and 52 replies. Show up there, follow the room's rules, and ask for conversations. Do not scrape it.
Do I need to write code?
No. The prompts on this page draft a plan and a month of growth. Code is a later choice. The founder site linked once below is where the build document lives, if you want it.
A separate site sells the agent build document and can build the product. Have this built
A two-week build starts at $10,000 on that site, after a $1,000 scoping fee.
