Micro-Acquisition Marketplace for Tiny SaaS
A marketplace where indie hackers buy and sell small software projects (sub-$5k MRR), the segment too small for Acquire.com or brokers, with standardized due diligence, escrow, and migration support baked in.

Market timing
Why now
The indie SaaS boom of 2020-2024 created a massive long tail of small software businesses, and now their builders are moving on. 'Build in public' normalized publicly sharing MRR, so the supply of sellable micro-SaaS is more visible than ever. Acquire.com (formerly MicroAcquire) moved upmarket toward $50k+ MRR deals after raising venture money, abandoning the sub-$5k segment where most indie projects actually live. That bottom tier transacts today, clumsily, over Twitter DMs, with no escrow or trust layer. The infrastructure gap is wide open.

Red Flags
ProBrutal two-sided cold-start with low transaction frequency. Unlike a recurring-revenue SaaS, a marketplace only earns when a deal closes, and tiny-SaaS sales are infrequent and lumpy, so revenue is unpredictable for a long time.
Trust and fraud are existential. A single high-profile scam (faked MRR, a buyer who doesn't pay, a seller who vanishes post-sale) destroys the reputation the whole marketplace depends on. Escrow + verification aren't features, they're the product.
Low LTV by nature. Sellers sell once and leave; buyers buy occasionally. Without becoming the ongoing 'home' for indie acquisitions (newsletter, community, repeat funds), you permanently re-acquire both sides.

The status quo, no escrow, no verification, no trust layer. Deals fall through or turn scammy. That friction is exactly your wedge.

How you'll get customers
Where your first customers realistically come from:
- Indie Hackers + r/SaaS + Twitter build-in-public, Your buyers and sellers are the same people posting MRR screenshots. Engage genuinely and share completed-deal stories as proof.
- A 'tiny SaaS for sale this week' newsletter, Curate listings into a weekly email, it becomes the destination buyers check and the place sellers want to be listed.
- Partnerships with indie-hacker podcasts + communities, Sponsor or guest on shows where serial sellers and small buyers already hang out (MicroConf-adjacent, Indie Hackers).

How to start
1
Manually broker 3 deals yourself. Find sellers in r/SaaS, Indie Hackers, and Twitter who've tweeted 'thinking of shutting this down', match them with buyers, learn the friction.
2
Build a simple listing site: seller submits MRR / tech-stack / reason-for-selling; you verify Stripe revenue via screenshot or read-only connection; buyers browse.
3
Add escrow (Escrow.com API or a manual process) so neither side gets burned, this trust layer is the entire reason the marketplace beats Twitter DMs.
4
Take a 7% success fee. After 20 completed deals, add a standardized due-diligence checklist + migration guide as your differentiation.

- Talk to 10 of them, ask about the problem, don't pitch. Look for real frustration.
- Collect a waitlist or take a pre-order to prove they'll act, not just nod.
- Build the smallest version that delivers the core value, a landing page plus one working feature. Don't polish.
