About
Mailwarm is a Rouen, France-based email deliverability and warmup platform — backed by Y Combinator (W20) with $150,000 in seed funding in 2020 — providing businesses and sales teams using cold outreach with automated email warmup services that improve sender reputation and inbox placement by simulating positive email interactions with a network of real email accounts. Founded in 2020 by Amine Benjelloun and Gonzague Hacher, Mailwarm reached $50,000 in monthly recurring revenue within months of launch with a 2-person team, serving businesses that rely on cold email outreach for lead generation and need to avoid the spam filters that flag new sending domains and low-reputation email accounts.
Web3 authentication and account abstraction infrastructure enabling gasless transactions and simplified dApp onboarding; ERC-4337 implementation allows dApps to sponsor gas fees on behalf of users and accept ERC-20 token gas payment for mainstream-accessible wallet experiences.
About
Biconomy is a Web3 infrastructure platform focused on making decentralized applications usable by mainstream audiences who are not familiar with cryptocurrency gas mechanics. Its core product implements account abstraction via ERC-4337, allowing dApp developers to sponsor gas fees on behalf of users, accept gas payment in ERC-20 tokens instead of native currency, and batch multiple on-chain transactions into a single user action. These capabilities transform the user experience from one requiring native token balances and technical awareness into something closer to a conventional web application workflow.
