Excited to announce Phishing Triage from @DoppelHQ. It’s our next agentic solution to operationalize response at scale. "Report phish" feeds are one of the most actionable intel feeds for any organization, and Doppel's platform is built to scale for today's AI world.
Three key differentiators about Doppel's triage product:
1. Agentic by default. No endless review queues but instant decisions and responses by agents.
2. Powered by Doppel threat intelligence. Our real-time brand protection feeds of DNS registrations, active phishing threats, and multi-channel IOCs allow you to catch threats before traditional email security solutions.
3. Integrated with the platform. HRM simulations automatically register as part of training, and agentic DRP auto takes down malicious threats.
Thank you to Kiran Arimilli, Aliya Rajwani, and Sahil Jain for building this product, and @TamirMSamman and Sameera Kelkar for bringing this to our customers.

Great hearing from Dave Roberts at @DoppelHQ's inaugural CISO Summit last week where our attendees got to hear from the most recent World Series champion. Though baseball and business are very different fields, we learned a lot about aligning a team around a single mission, operating in a highly competitive environment, and upholding a high standard for everything we do.
Thank you Dave for all the great leadership insights, and congrats again to you and the @Dodgers on being world champions!
Looking forward to our next CISO Summit.
The @G2dotcom Winter 2026 reports are in, and we’re honored by the recognition.
A few highlights we’re recognized for:
-Leader in Threat Intelligence & Brand Protection
-Momentum Leader
-Easiest To Do Business With
-Best Support
-Best Est. ROI
-Users Most Likely To Recommend
At Doppel, customer obsession is at the heart of everything we do. These recognitions mean so much because they reflect the trust, partnership, and support of the incredible customers who inspire us every day. Every badge is a reminder that protecting brands, employees, and customers isn’t just our mission: It’s our responsibility, and we’re honored to do it alongside you.
To our customers: We’re deeply grateful. Thank you for pushing us to be better, move faster, and innovate with purpose.
We're so grateful that @BessemerVP decided to double down on our partnership, leading our Series C funding. @rahul_madduluri and I sat down with @TheValuesVC to discuss how we're just getting started in our mission to protect the world from social engineering attacks every day. Thank you to Elliott Robinson, @andrewaaren, the Bessemer Venture Partners team, and all of our incredible investors for accelerating the next stage of growth for Doppel.

Today, @DoppelHQ was named to the @FortuneMagazine Cyber 60 as an Early Growth Stage company to watch, presented by Fortune, @lightspeedvp, and @AWSstartups . Recognition is great fuel, but we’re just getting started building the first and best AI-native Social Engineering Defense (SED) platform.
In the past few months, we have expanded our product portfolio to simulate the impersonations we take down, as we now orchestrate deepfake “vibe-phishing” AI agents that average 6 minute phone calls with the help desk, unlocking modern Security Awareness & Training (SAT) and Red Teaming capabilities. From one social engineering threat graph platform, our customers can now detect, takedown, simulate, and train their organization instead of relying on a multitude of point solutions.
And the problem is only growing. The FBI’s 2024 IC3 report shared that there was $16.6 billion in reported losses from phishing, BEC, and fraud, and $25 million was recently lost in a deepfake executive impersonation video conference attack. Doppel’s reason for existence is to win this battleground, as we’re on a mission to protect humanity from these threats.
To our customers and partners: Thank you for trusting us and partnering with us to innovate on social engineering defense. To the Doppel team: Thank you for hustling and building every day for our customers and partners. And to every security leader asking how to protect their executives, their employees, and their customers from these increasing attacks, we’d love to help you.
I really am grateful to work with such a talented and mission-driven team at @DoppelHQ!
If you're an engineer (in SF or NYC) and want to defend reality, join us and help fight AI with AI!
Just got home from Vegas. This was the biggest @BlackHatEvents ever for @DoppelHQ, and in particular, our discussions with customers and partners around social engineering stood out:
- Social engineering is becoming the top cyber insurance claim, even more than data breaches.
- Teams are building social engineering defense programs, but they currently have several point solutions across executive protection, brand protection, anti-phishing, anti-fraud, threat intel, and takedown response.
- Vishing campaigns are rampant and targeting the help desk, finance teams, and HR teams indiscriminately.
- Scattered Spider or threat actors with similar TTPs are incredibly top of mind for practitioners, executives, and their boards.
It was energizing to hear from the ecosystem about how we can build more to combat the existential threats from AI. Thankful for all the time our community spent with us, and we have upcoming product releases to strengthen our platform and customers. Can't wait to share what we've been working on!
Phishing is not a minor inconvenience. It is a significant driver of breaches and financial losses for businesses globally. The FBI reported $3 billion in losses from business email compromise in the U.S. alone last year.

Building @DoppelHQ with @KevinTian00 these last 3 years has been an epic journey. Doppel has evolved from a manually updated spreadsheet to a platform that autonomously scans billions of potential social engineering attacks -- and eliminates them with an AI cybersecurity agent.
@DoppelHQ now protects notable enterprises, their employees, and hundreds of millions of their customers around the world. I'm very proud of the work we do, especially at a time when AI-driven social engineering is more dangerous than ever. The world-class team at Doppel moves really, really fast to outpace attackers and build something great. It's been an absolutely joy to work with such a passionate and driven group.
With this Series B, I couldn't be more excited to work with Elliott Robinson (@TheValuesVC) and @BessemerVP, along with @a16z, @southpkcommons, @sozo_ventures, @9yardscapital, @SCV_Cyber, @scriptcapital, and Sabrina Hahn to make Doppel an even better solution for our amazing customers.
We're hiring across many roles (especially eng). DM me if you're interested!
Authenticity is under attack—and @DoppelHQ is on the front lines of the defense. That's why @TheValuesVC and Andrew Ren are leading Doppel's $35M Series B. Congratulations to @KevinTian00, @rahul_madduluri, and the entire Doppel team on this exciting milestone!

@rahul_madduluri and I started @DoppelHQ in 2022, just as ChatGPT and generative AI were emerging. Today, we now have live AI agents processing billions of potential threats to business’s customers, employees, and executives. Tomorrow, we will be living in a world where AI can create a deceptive digital experience through any medium, and at Doppel, we’re on a mission to combat this.
We could not be more grateful for @RashiShrivast18, one of the preeminent writers on AI, to share our story for our Series B. Read more in @Forbes here: https://t.co/RNYXfUCwI1
Thank you @TheValuesVC and Daniel Pyykonen for contributing your perspectives as well!
Today, I’m thrilled to share @DoppelHQ has raised a $35 million Series B, led by @BessemerVP, with participation from new investors @9yardscapital and @sozo_ventures, and existing investors like @a16z, @southpkcommons, @SCV_Cyber, @scriptcapital, and @sabrinahahn.
Three years ago, @rahul_madduluri and I started Doppel shortly after the arrival of ChatGPT, anticipating the major threats AI would bring to the world. Since then, we’ve worked every day with our customers, almost 200 now, to build the social engineering defense platform, targeting everything from brand impersonation to executive protection to multi-channel phishing.
Since inception, we’ve maintained a 230% CAGR, and we saw a 400% growth in enterprise customers in just the past year. We’re now processing 100 million plus traditional and emerging indicators every day, with median takedown times of phishing sites in less than 1 hour.
Thank you to the many customers, partners, and investors who’ve joined our team in the mission to combat social engineering threats. It’s still day 1 at Doppel, and we’re just getting started.
