Halliday funding, valuation and investors

Overview

Halliday is a San Francisco blockchain infrastructure company founded in 2022 by Griffin Dunaif and Akshay Malhotra. It built the Agentic Workflow Protocol (AWP) — a workflow engine that lets developers automate onchain processes like L2 onramps, recurring stablecoin payments, cross-chain bridging, and treasury management without writing custom smart contracts for each use case. Halliday Payments is the first-party app on top of the protocol. a16z crypto led a $6M seed in 2022 and a $20M Series A in March 2025, bringing total funding above $26M.

Why Halliday is interesting

Halliday pivoted from gaming 'play now, pay later' to core Web3 infrastructure and shipped production workflows for ApeChain and Avalanche before raising a $20M Series A. The bet: AI agents need immutable onchain guardrails, not hand-written Solidity for every flow.

Product & use cases

Halliday's Workflow Protocol provides composable onchain automation with predefined guardrails for AI agents and software systems. Halliday Payments offers a single-click interface for fiat onramps, bridging, swaps, and offramps — already deployed with partners including ApeChain, Avalanche Core Wallet, and DeFi Kingdoms.

• One-click user onboarding to L2s and game economies via Halliday Payments
• Recurring stablecoin subscriptions and B2B agent payments with workflow guardrails
• Cross-chain treasury management without bespoke smart contract development per flow

Key facts

• Series A (Mar 2025): $20M led by a16z crypto; total funding $26M+ (Halliday blog)
• Production deployments with ApeChain, Avalanche Core Wallet, DeFi Kingdoms, Metis
• Pivoted from consumer gaming financing to core workflow/payments infrastructure
• Team includes alumni from Alphabet, Meta, Netflix, Stripe, and Compound

Competitive landscape

Edge: Halliday shipped a proprietary workflow engine in production for over a year before the Series A — unusual for crypto infra startups. Team backgrounds span Alphabet, Meta, Stripe, and Compound, combining Web2 payments UX with onchain composability.

Web3 developer tooling is splitting between low-level SDKs and higher-level abstractions. Halliday targets teams that need payments and automation fast — games, L2s, wallets — without auditing new contracts per feature. Risk: protocols may insource workflows as standards mature; advantage: production integrations and a16z crypto's repeat investment.

• Biconomy adjacent

  Account abstraction and gasless transaction middleware; focuses on UX simplification rather than full workflow orchestration.

• Lit Protocol adjacent

  Programmable key management for Web3 automation; complementary infrastructure layer vs Halliday's workflow engine.

• Custom smart contract stacks alternative

  Default approach for DeFi teams; slower to ship but maximally customizable versus Halliday's no-code workflow abstraction.

Notable stories

• Halliday originally launched as a 'play now, pay later' gaming financing product before pivoting to the Agentic Workflow Protocol — a shift reflected in a16z crypto leading both the 2022 seed and 2025 Series A.
• CEO Griffin Dunaif told VentureBeat the company sees expansion beyond Web3 into fintech and banks entering crypto via stablecoin subscriptions and programmable treasury management.
