Solo founders ship micro-SaaS tools all the time—Chrome extensions, Shopify apps, niche APIs, lightweight B2B automation. They grind to $300–$1,000 MRR, then get bored, burned out, or distracted by a shinier idea. They want out. And right now, their "exit strategy" is a Twitter DM, a PayPal invoice, and a handshake.
That's a market begging for infrastructure.
The play is a micro-acquisition marketplace for deals under $15,000 with automated revenue verification, standardized code checks, deal-room escrow, and a transfer checklist that actually works.
Even at just a dozen monthly closings with average deal sizes around $5K–$7K, the math lands at $4,500–$12,500 MRR on minimal infrastructure costs. Execute, learn, then scale.
Do it well enough, and you're sitting on something far more valuable than a marketplace: a proprietary dataset of micro-SaaS valuations, risk scores, and buyer-seller reputation graphs.
The Carfax for side projects. Nobody owns it yet.
The Supply Exists. The Trust Layer Doesn't.
The global SaaS market hit roughly $315 billion in 2025 and is growing at around 20% CAGR. The interesting action is at the bottom—the micro-SaaS layer where solopreneurs and two-person teams target $1K–$20K MRR with hyper-specific tools. Nearly 40% of indie SaaS founders operate solo. Many ship multiple products a year. A meaningful percentage plateau, pivot, or lose interest.
When that happens, they want to sell quickly. The demand is already transacting: Microns.io facilitated 40 deals worth about $185,000 in 2023 (average deal size ~$4,600), and their 2025 newsletters show accelerating volume—$22.5K GMV across 4 deals in April, $45K across 9 deals in June. Little Exits (formerly Tiny Acquisitions) markets 750+ verified projects and 25,000+ indie hackers, carving a lane for sub-$100K side-project liquidations. Acquire.com, the big player, operates at mid-six to seven figures—a founder offloading a $5K Chrome extension doesn't get much love there.
The gap sits in deals between $1,000 and $15,000, where the overhead of a proper acquisition process feels absurd relative to deal size, but the risks of DM transactions are very real. Misrepresented revenue. Code that doesn't compile. Credentials never transferred. Domains stuck in someone else's registrar.
Generic escrow only solves one problem: holding the money. It doesn't verify whether revenue numbers are real, whether the codebase runs, or whether a buyer gets a reasonable inspection window post-handoff. And selling a micro-SaaS product involves at least six separate asset transfers—the codebase, the domain, the hosting account, the payment processor (Stripe, Paddle, Lemon Squeezy), the support and email accounts, and third-party API keys. Generic escrow has no concept of this. The transfer checklist alone is a product.
Escrow is a feature. Underwriting is the moat.
The Competitive Map
You're entering a space with existing players, which is a good sign. Each leaves a clear opening.
Acquire.com connects buyers and sellers across all deal sizes, with median private SaaS revenue multiples around 4–5x. Their sweet spot is six- and seven-figure deals, and the platform's economics don't incentivize servicing a $4,000 listing.
Microns.io is the closest direct competitor, with listings from $200 to $500,000, zero commission, and their own transfer service. It operates more like a listing board with escrow bolted on—ratings and basic deal facilitation, but no automated revenue verification, no code quality signals, no standardized underwriting. They're iterating (adding ratings, transfer support), but verification isn't the core product.
Little Exits focuses on sub-$100K deals for indie hackers. Built with no-code tools, reportedly generating $3K+/month as a side project. Offers Stripe-connected verified metrics, in-app messaging, and a built-in exchange flow. Scrappy and well-positioned culturally, but treats verification as an access feature rather than the main product.
Flippa is the oldest player (founded 2009, 1.5M+ users), skewing toward content sites, e-commerce, and larger deals. The brand carries baggage from years of inconsistent vetting.
The wedge: none of these platforms surface a structured, API-verified "business card" with both revenue telemetry and repo-level health indicators as the primary UI. They all have verification elements, but nobody has made underwriting and transfer checklists the product. That's the opening.
