- OnRe
Led · Series A · May 2026
OnRe operates as a regulated on-chain reinsurer and issues ONyc, a token designed to provide exposure to a diversified portfolio of reinsurance risks. ONyc is integrated with major DeFi protocols on the Solana blockchain and can be used as collateral for loans and in yield strategies. The company recently closed a $5 million Series A and has a planned up-to-$25 million token investment from Forward Industries. The articles do not disclose revenue, user metrics, founding year, or location. OnRe's strategy emphasizes combining regulated reinsurance exposure with DeFi composability via Solana integrations.
- Exponent
Participated · Seed · Apr 2026
Exponent operates an onchain yield exchange on Solana that lets users convert variable yield exposures—such as staking or lending returns—into fixed-rate or leveraged positions via an onchain interest rate order book. The company is updating its platform to introduce fully onchain order book functionality and strategy vaults that allow asset managers to package interest-rate strategies for users under predefined governance policies. Exponent has processed over $2 billion in yield volume across more than 35,000 users since launching in late 2024 and generates revenue from fees on issuing derivative positions tied to yield assets and from trading activity. It is onboarding partners and preparing markets across stablecoins, real-world assets, and Solana-denominated products, with early strategy-vault partners including RockawayX, Hastra, OnRe, and Solstice. The startup operates with a 12-person team, plans to allocate part of its recent funding toward security (audits and a bug bounty), and intends to remain focused on building on Solana. The company began fundraising for its seed in May and closed the round in August.
- BetHog
Led · Series A · Apr 2026
Founded in 2024 by the creators of FanDuel and based in Edinburgh, BetHog operates a crypto casino and sportsbook available in 14 languages and accepting deposits in 10 cryptocurrencies. Its product mix includes classic casino games, exclusive titles, and AI-powered live dealers; the company launched its first AI blackjack dealer, Sunny, in October 2025 and reports it as one of the most played games. BetHog has introduced Sentient Studios, a B2B platform to let other operators deploy AI dealers across live casino offerings. The company plans to expand its AI dealer capabilities later in the year to include Baccarat and Roulette. BetHog is regulated, backed by investors from sports, crypto and gaming, and has raised a total of €13 million to date following the Series A.
- Silhouette Exchange
Participated · Seed · Mar 2026
Silhouette Exchange is building the first shield exchange on Hyperliquid, a privacy-preserving layer that batches and matches orders off-chain within Trusted Execution Environments (TEEs) and settles them on-chain. By combining off-chain private order matching with on-chain settlement, the platform aims to enable more secure and efficient trading environments for digital assets. The company positions its architecture as hybrid infrastructure that preserves privacy while maintaining on-chain finality. Silhouette raised an $8 million Seed round to accelerate development and expand its privacy-preserving infrastructure. The financing structure included a CLA and a Token Warrant, reflecting a blend of equity-like and token-based capital. The article does not provide revenue, user, or other operating metrics.
- Solmate
Participated · Equity · Sep 2025
Formerly known as Brera Holdings (Nasdaq: BREA), Solmate is pivoting from its sports-club roots into a Solana-centric digital asset treasury and infrastructure provider. Under the leadership of new CEO Marco Santori, the firm plans to deploy bare-metal servers in Abu Dhabi to run high-performance Solana validators, aiming for superior staking yields while accelerating regional blockchain adoption. The company will continue managing Brera’s football assets, but its primary focus is now on accumulating and staking SOL and offering institutional-grade infrastructure. Strategic alignment with the Solana Foundation includes granting the foundation two board seats, underscoring close technical collaboration. New board members also include renowned economist Dr. Arthur Laffer and RockawayX CEO Viktor Fischer. With a dual stock listing in the works and substantial new capital, Solmate intends to position itself as a key enabler of the UAE’s digital-transformation agenda within the Solana ecosystem.
