Tines, which helps enterprise security teams automate repetitive workflows, adds $11M to its $4.1M Series A round from six weeks ago, led by Accel
Tines, a cybersecurity startup that helps enterprise security teams automate repetitive workflows, has added a further $11 million to its series A funding round.
Context & Ripple Effects
At the end of 2019, Tines was a Dublin startup that had raised just a $4.1M Series A six weeks earlier — and Accel doubling down with an $11M extension so soon is the signal here. The firm had form in the category, having led Tenable's $250M Series B and backed email-security startup Tessian's $13M Series A the year before.
The bet paid out along a steep curve: the extension set up a $26M Series B in 2021, extensions through 2024 near a $600M valuation, and by February 2025 a $125M raise at a $1.13B valuation after repositioning around AI-driven automation.
First-order effects
- Tines' Series A effectively quadruples to ~$15M within six weeks, giving the security-workflow-automation team an outsized runway relative to its stage while Accel secures a larger early position.
Second-order effects
- A top-tier firm paying up twice in six weeks marks security-team workflow automation as a fundable category, pressuring rivals in the space to raise comparable war chests ahead of enterprise procurement cycles.
Third-order effects
- If the trajectory holds — from no-code task automation toward AI handling broader business operations, as the later rounds show — security orchestration consolidates into general-purpose automation platforms rather than point tools bolted onto SIEM stacks.
The trend: Security workflow automation is evolving from niche SOAR tooling into AI-native enterprise platforms, with early backers like Accel compounding positions across successive rounds.
