Micro SaaS is SaaS built for a small, specific audience by one or two founders, with the explicit constraint of staying small. The math is different from venture-scale SaaS: the target ARR is usually $100K to $500K, not $10M, and the distribution model has to work without paid acquisition.
This is a playbook for testing a micro SaaS idea against the four dimensions that matter most for the small-and-sustainable shape.
Dimension 1: The buyer has to be very narrow and very reachable
Micro SaaS works when the target buyer is a specific segment that can be reached through one or two organic channels. "Sales teams" is too broad. "Sales reps at venture-backed B2B SaaS companies between $1M and $5M ARR who use HubSpot" is narrow enough that you can find them, talk to them, and acquire them organically.
The test: write down the buyer persona in three sentences with specific company size, role, tool stack, and industry. Then identify the one or two channels where these buyers cluster (a specific subreddit, a specific Slack community, a specific newsletter, a specific conference).
If you cannot name the channel where the buyer clusters, the distribution math will fail.
Dimension 2: The wedge has to be a specific workflow gap
Micro SaaS does not win on broad capability. It wins on a specific gap an existing tool does not address well. The buyer already has a tool; your micro SaaS plugs into or replaces a specific piece of it.
The test: write down the existing tool the buyer uses. Then describe the specific workflow gap your tool fills that the existing tool cannot. "Faster" and "cheaper" are not gaps; "automated handoff between Stage X in HubSpot and Stage Y in Linear that currently takes 15 minutes per deal" is a gap.
Dimension 3: Pricing has to be in the micro SaaS band
Micro SaaS price points cluster between $10 and $50 a month for individual seats or between $99 and $499 a month for small-team SKUs. Below $10, the unit economics rarely work for an indie founder. Above $50 for individuals or $499 for teams, the buyer expects enterprise-grade support that an indie founder cannot deliver.
The test: pick the price band based on the buyer profile. Individual buyer with budget control = $10 to $50. Team buyer with manager approval = $99 to $499. Confirm comparable tools in the segment sit in the same band.
Dimension 4: The distribution channel cannot require paid acquisition
Paid acquisition for micro SaaS rarely works because the LTV is too low to absorb meaningful CAC. The math has to work on organic.
Common organic channels for micro SaaS:
- **Owned audience.** Founder's existing newsletter, X following, LinkedIn presence. - **Niche community.** Specific subreddit, Slack community, Discord. - **Content + SEO.** Specific long-tail keywords that the buyer searches. - **Word of mouth.** Tool-specific viral loops, referral mechanics. - **Integration directories.** App stores of larger platforms (Slack, Notion, HubSpot, Zapier).
The test: name the specific channel and the realistic acquisition volume from it. If the answer is "we will market it on social", that is not a channel. If the answer is "we will rank for 'HubSpot Linear sync' which has 200 searches a month and the top three results are weak", that is a channel.
A worked example: a tool that syncs Lovable build threads to Linear tickets
The idea: a micro SaaS that automatically creates Linear tickets from Lovable's build conversations, so a founder using Lovable for vibe coding does not lose track of feature requests, bugs, and follow-ups across tools.
- **Buyer:** solo founders or small teams using Lovable for vibe coding and Linear for issue tracking. Reachable through r/vibecoding, the Lovable community Discord, and indie-hacker channels. - **Wedge:** Lovable does not have a Linear integration. Manual copying between the two tools is the current workaround and costs each founder about 30 minutes a week. - **Pricing:** $19 a month for the individual tier. $99 a month for a small team tier (up to 5 seats). - **Channel:** rank for "Lovable Linear sync" and similar long-tail searches. Build-in-public posts on X. Listing in the Lovable community channel when product is ready. Listing in the Linear integration directory if accepted.
All four dimensions clear. The micro SaaS is worth building.
The math: 500 paying individuals at $19 a month + 50 paying teams at $99 a month = $14,500 MRR or $174K ARR. Realistic to hit in 18 to 24 months from launch with consistent organic distribution. Enough to pay one full-time founder.
