Impart Security - Growth Capital
$10.99M Raised
When you’ve built four WAF products before breakfast and hold patents that read like sci-fi screenplays, you don’t chase trends, you engineer inevitabilities. That’s the rhythm Jonathan DiVincenzo, Marc Harrison, and Brian Joe brought when they broke cover with Impart Security. If Signal Sciences was the mixtape, Impart is the platinum LP, tighter production, sharper bars, and zero filler.
Founded in 2021, Impart has weaponizing the future of API security from a lean SF base. Ignore the noise, this isn’t a garage band trying to be heard. It’s a focused trio of engineers-turned-operators who’ve scaled the edge and saw the architecture shift coming before the ink dried on Fastly’s $775M acquisition of their last act.
Their pitch isn’t wrapped in hype. It’s an API security platform engineered for modern architectures, IaC-native, runtime-tuned, and AI powered. Think DAG based rule dependencies, WebAssembly based protection, and a workflow layer that executes. Since 2024, Impart’s AI Workflows have been breaking down firewall rules like a battle rapper breaks down bars, fast, contextual, and smart enough to know when to pivot.
That’s how they turned heads at CRV, again. CRV didn’t just show up in the seed, they stuck around for the $10.99M May 2025 round, anchoring a funding story that totals $20.58M without ever throwing a label on the round. Series A? Series B? Who cares when your execution is this tight and your product speaks fluent enterprise.
No hype. Just Crossbeam and Latio Tech in production, AWS Marketplace distribution, and average deals clocking in between $45-75K. They’re not chasing checkmarks. They’re closing business.
In a market where 14 new API security players popped up in 2024 alone, Impart isn’t playing defense, they’re building an AI-led offense. With patents granted, two more pending, and WASM optimization on the hiring board, the mission’s clear: execute or get out of the way.
And let’s talk revenue: $2.1M in 2023, an estimated $4.8M this year, and eyes on $11.2M for 2025. This isn’t just upward, it’s calculated. Gross margins are climbing. R&D isn’t just a line item; it’s a conviction play.
There’s risk. Platform dependency on AWS. Saturation fatigue. But here’s the rub: if you’re betting on a founder-led team that’s lived the edge, built the infra, and now owns the security layer, Impart’s where that bet looks smart.
Congrats to Jonathan, Marc, and Brian for not just raising capital, but building something that understands the stakes. And shoutout to CRV, Haystack, 8-Bit Capital, and O'Reilly AlphaTech Ventures, this syndicate didn’t just invest in a company. They backed a crew that already wrote the manual and tossed it in the shredder.
