Last year, we shared our predictions about what could shape the year ahead. This time, we’re taking a different route. Rather than claiming to know what the future holds, we want to share what we hope to see: a 10-point wishlist of ideas, problems, and products we’d love founders to take on in 2026. By anchoring these reflections, we gain a nuanced understanding of where the next set of meaningful opportunities may emerge across Infrastructure, DeFi, and Consumer – and in how evolving regulation will shape the ground beneath them.

We’re excited to announce that Greenfield is leading Semantic Layer’s $1.5M Series A funding round, which brings the total funding to $5M. Semantic Layer is building the execution and sequencing infrastructure for the Agent Economy. As autonomous AI agents begin to transact, trade, and collaborate on-chain, Semantic Layer gives dApps and agents sovereignty over how these interactions are executed, empowering them to define transaction sequencing, capture MEV fairly, and design entirely new economic primitives.

We’re excited to announce that Greenfield is participating in nuConstruct’s $6M seed funding round. nuConstruct is developing TOOL, an out-of-protocol solution to scale Ethereum L1 block times from currently 12 seconds to 1 second subslots via early confirmations, which guarantee both inclusion and execution results of transactions.

We are excited to announce our participation in Warlock Lab's $8M seed funding round. Warlock is a crypto-native trading firm focusing on market making and MEV strategies across chains, as well as orderflow monetization, helping DeFi protocols improve their efficiency and sustainability by re-capturing value otherwise lost due to malicious MEV.
