Top 6 Platforms to Buy & Sell Startups in 2026

Discover the top marketplaces to buy and sell startups in 2026, including Microns, TrustMRR, Flippa, Acquire, FE International, and Empire Flippers.

Here are 6 marketplaces worth checking in 2026 on Best AISO.

1. Microns.io

Best for: Micro-startups, micro-SaaS, side projects, mobile apps, and small online businesses.

Microns.io is a managed marketplace focused on smaller startups and online businesses. It is a good option for founders who want to sell a small startup and for buyers who want to acquire an existing project without spending millions of dollars.

Microns says it has helped complete 150+ acquisitions and has facilitated more than $850,000 in startup sales. It also says that 80% of accepted startups were acquired.

How Microns helps sellers

Sellers can submit their startup for review. Microns helps improve the listing, connects sellers with verified buyers, and supports the deal process.

It also handles important parts of the transaction, including the purchase agreement, invoice, payment, payout, and transfer process. There are no listing fees, and sellers pay a success fee only when they sell.

How Microns helps buyers

Buyers can browse startups with information such as revenue, business type, and asking price. The platform focuses on businesses that already have traction, which can make it easier to find a startup that is ready to grow.

Rating and user reviews

Microns does not have a large independent review database like Flippa or Acquire. However, its website features several positive founder testimonials from people who bought or sold projects through the platform. Users commonly mention a fast and easy process and helpful support.

Best choice if: You want to buy or sell a smaller startup, micro-SaaS, app, or side project. Link: https://microns.io/

2. TrustMRR

Best for: Buying and selling startups with verified revenue data.

TrustMRR is a startup revenue database and acquisition marketplace. Its main focus is making startup revenue easier to verify before a buyer makes an offer.

Founders can connect their payment systems to verify revenue data. Buyers can then browse startups and contact founders about an acquisition.

How TrustMRR helps sellers

Sellers can list their startups and show verified revenue information. This can help build trust with potential buyers because buyers can see real revenue metrics instead of relying only on claims from the seller.

TrustMRR charges a 3% marketplace closing fee, split between the buyer and seller. Escrow.com fees are added separately.

How TrustMRR helps buyers

The biggest advantage is revenue verification. Buyers can use verified metrics to find startups that match their budget and goals.

When a deal moves forward, TrustMRR works with Escrow.com. The buyer sends the money to escrow, the seller transfers the agreed assets, and the funds are released after the transaction conditions are met.

Rating and user reviews

TrustMRR is newer than platforms such as Flippa, so it does not yet have the same large volume of independent public reviews. Its strongest review signal is its focus on verified startup revenue and its transparent escrow process.

3. Flippa

Best for: The widest range of online businesses and digital assets.

Flippa is one of the biggest online marketplaces for buying and selling digital businesses. It has been operating since 2009 and says more than 450,000 deals have been completed.

Flippa currently has a 4.2 out of 5 rating on Trustpilot from more than 3,200 reviews. Many reviewers praise the platform's easy-to-use marketplace and support during transactions. Some reviews also mention slow customer service or listing issues, so buyers should still do their own due diligence.

Best choice if: You are buying or selling a profitable SaaS or technology startup.

5. FE International

Best for: Larger SaaS, ecommerce, and digital businesses that need M&A advice.

How FE International helps sellers

FE provides valuation, exit planning, buyer outreach, due diligence, negotiation, and transaction support.

This can be useful for a founder who is selling a larger company and wants expert help instead of managing the entire sale alone.

How FE International helps buyers

Buyers get access to businesses that have gone through a detailed review process. FE helps with financial analysis, due diligence, valuation, and the M&A process.

Rating and user reviews

FE International has a 5.0 out of 5 rating on G2 from 3 reviews. Those reviews praise its professionalism, expertise, responsiveness, and valuation work. Because the number of reviews is small, the rating should be treated as a limited signal rather than a full picture of customer experience.

FAQs About Buying and Selling Startups

1. Where is the best place to buy a startup?

It depends on your budget and the type of startup you want. Microns.io is a strong option for micro-startups and small SaaS businesses. TrustMRR is useful when verified revenue is important. Flippa is a good choice when you want a very large selection.

2. How much does it cost to buy a startup?

There is no single price. Small side projects can sell for a few thousand dollars, while established SaaS and ecommerce companies can sell for hundreds of thousands or millions of dollars.

The price usually depends on revenue, profit, growth, customers, traffic, business model, and how much risk the buyer sees.

3. What should I check before buying a startup?

Always check the revenue, profit, expenses, customers, traffic, growth, technology, competitors, and reason for the sale.

Ask for proof of important numbers. Never buy a business based only on a seller's claims.

4. How long does it take to sell a startup?

It depends on the business and asking price. Small businesses can sometimes sell quickly, while larger companies can take weeks or months because of due diligence, negotiations, legal work, and financing.

For example, Flippa reported that $1 million-plus businesses matched with buyers in a median of 27 days in H1 2026, but the full closing process took longer.

5. Is buying an existing startup better than building one?

Not always, but buying can save time. Instead of starting with zero customers and zero revenue, you may acquire an existing product, customer base, brand, traffic, and revenue.

The tradeoff is that you pay for what has already been built, and you must carefully check the business before buying.

Conclusion: Buy & Sell Business in 2026

There is no single best marketplace for everyone.

For small startups and micro-SaaS, I would start with Microns.io. It is focused on smaller acquisitions and gives founders a simple way to buy and sell existing projects.

For a large selection of digital businesses, Flippa is hard to ignore. Its global buyer network, large number of listings, and long track record make it one of the biggest names in online business acquisitions.

For buyers who care about verified startup revenue, TrustMRR is another marketplace worth watching. Its focus on verified MRR and revenue data can make it easier to compare opportunities.

My top 3 picks are:

• 🥇 Microns.io for micro-startups and small SaaS

• 🥈 Flippa for the widest marketplace

• 🥉 TrustMRR for verified startup revenue

Before buying any startup, remember one simple rule: trust the numbers, not just the story. Always do your own due diligence.
