Six Exciting Web3 Startups to Watch in 2025

According to the Web3 Industry Report 2025 by StartUs Insights, over 3,000 active startups now operate in the space, growing at an annual rate of more than 28%.

While artificial intelligence continues to dominate investor priorities, Web3 startups are quietly building real-world use cases, raising millions, and executing strategic acquisitions.

Here are some of the most promising Web3 and crypto startups to track in the coming months.

Everminer: A Perpetual Bitcoin Mining Contract

Everminer has introduced a novel concept in crypto mining—perpetual Bitcoin mining contracts. With a one-time payment, users receive ongoing Bitcoin rewards through the purchase of “Everhashes,” each representing 1 TH/s of lifetime mining power.

Founder Max Matriniski describes it as “similar to cloud mining, but with a fundamental difference—there’s no time limit.”

“You can buy as many Everhashes as you want, and they’ll keep mining indefinitely. Unlike most cloud contracts, these are tradable assets with liquidity on our own internal marketplace,” he added.

The platform targets non-technical users by simplifying access and increasing transparency.

“When we sell an Everhash, we reinvest that money into more mining equipment, which grows our Bitcoin reserve—faster than our obligations,” said Matriniski. “That reserve is publicly visible on-chain. Today we hold over 1.5 BTC, and that’s just the beginning.”

Marsbase: A Secondary Market for Tokenized Private Assets

Marsbase operates as a decentralized secondary market for illiquid Web3 assets like SAFTs, SAFEs, locked tokens, and RWAs. 

With $1.8 billion in listed assets and over $60 million in trading volume, it is positioning itself as critical infrastructure for the next phase of tokenization.

“We help companies that are already large but not yet ready for a traditional IPO,” said co-founder Denis. “If they don’t have a token yet, we enable them to raise capital through tokenized IPOs on blockchain.”

About 70% of Marsbase transactions occur over-the-counter. The remaining 30% comes from sectors like real estate, infrastructure, and entertainment.

“Our clients range from funds seeking partial exits before vesting ends, to founders looking for strategic liquidity. We’ve also worked with film studios linked to Marvel and Bollywood, and gaming studios backed by Epic Games,” Denis explained.

AirBTC: Bitcoin-Powered Travel Platform

AirBTC is a peer-to-peer accommodation platform where users pay only in Bitcoin. 

With 500+ listed properties—15% of them in El Salvador—it aims to make international travel cheaper by eliminating exchange fees and banking charges.

“We’re solving real problems people face when traveling,” said founder Seifert. “The process is instant and very simple.”

He said the platform’s future includes broader payment support. “We plan to accept credit cards and stablecoins soon, in addition to Bitcoin.”

While digital nomads are a key user base, AirBTC also targets everyday travelers.

“A family in Russia, for example, might struggle to use Airbnb or send international transfers,” said Seifert. “With AirBTC, they can just use a USDT wallet to book a place to stay.”

The company is now expanding in Latin America, especially in Brazil and Colombia, while continuing to focus on El Salvador, Costa Rica, Mexico, and the Dominican Republic.

Pin To Pay: Crypto Payment Infrastructure Expands in Latin America

Pin To Pay is the consumer-facing brand of UANT, a company offering crypto-native financial infrastructure. Its tools include Telegram-based wallets and white-label APIs for companies seeking to bypass intermediaries like Visa or Mastercard.

“We offer one of the most complete payment solutions in the market,” said co-founder Guntis Siugals. “That includes tools for consumers and APIs for companies that want to meet modern demand.”

Siugals said Latin America is a key focus for growth. “Countries like Brazil and Mexico are dynamic markets with strong digital adoption,” he said. “PIX is a global benchmark, and we plan to integrate it into our services.”

He added that the company plans to take a local approach: “We want to enter each country with respect for its culture and needs.”

One Way Block: Automating Live Ops for Game Studios

One Way Block (OWB) aims to cut the cost and complexity of running online games by replacing manual operations with AI-powered systems. Its key product, the AI Game Master (AI GM), automates events in real time based on player behavior.

“When you launch a game, you usually need a large team to run A/B tests, adjust parameters, and create events,” said co-founder and CTO Slav Pankratov. “That’s expensive and time-consuming. Our tools replace that team with an automated system that’s more efficient.”

OWB’s own game, Clash of Coins, serves as a testbed for its AI systems. The browser-based strategy game has over 500,000 registered users and 30,000 daily active users.

“Our AI Game Master works like a 24/7 designer,” Pankratov explained. “If it detects that gameplay is getting boring, it automatically triggers events—like a bomb storm or a virus—to re-engage players.”

After raising a $750,000 pre-seed round, the crypto startup now aims to close a seed round and expand its toolset.

Nebula3 GameFi: Turning Web2 Indie Hits into Web3 Games

Nebula3 GameFi is bringing top-performing indie games from Web2 platforms like App Store, Play Store, and Steam into the Web3 ecosystem. It adds token economies, wallet integrations, and digital asset systems to validated games.

Founder Jun Seo says the company has already achieved strong traction: “We’ve onboarded over 630,000 users and 191,000 connected wallets—using just one game.”

Nine more titles are currently being adapted, each with proven Web2 performance. The startup’s model is capital-efficient, rebuilding each game for Web3 for around $50,000, often in co-development partnerships with game studios.

“We aim to scale a library of games with modern monetization and engagement mechanics,” Seo said.

The team has previously generated $13 million in traditional gaming revenue and 40 million downloads. 

Now in its pre-seed stage, Nebula3 is raising $2 million with a token price of $0.02 and no vesting period. The round values the project at a $20 million FDV.Overall, AI may dominate the funding headlines, but Web3 startups are now executing on long-awaited utility. These companies are building transparent systems, real-world integrations, and sustainable business models.
