🎉 We're thrilled to share that we have led Buzz Solutions' $20M #SeriesA! 💡Utilities are quickly facing converging crises: soaring power demand from AI and infrastructure build-out, increasingly frequent extreme weather events, and record wildfire risk, while burdened by their own aging physical infrastructure. Buzz addresses this with PowerAI, an AI-powered visual inspection platform that connects inspection data, asset records, and utility workflows into a single intelligence layer for the physical grid. Built on the industry's largest proprietary data set, PowerAI enables teams to prioritize urgent maintenance, cut infrastructure-related risk, and make proactive, informed decisions before disaster strikes. ⚡As a result of analyzing hundreds of thousands of physical assets, Buzz is trusted by some of the largest utilities in North America—including Dominion Energy, American Electric Power, and the New York Power Authority—and over the past year tripled its customer count while growing revenue by 400%. Congratulations to Co-Founders Kaitlyn Albertoli (CEO) and Vikhyat Chaudhry (CTO)—and to our co-investors GoPoint Ventures, HearstLab, and Blackhorn Ventures!

🚀 Congratulations to DataBahn on closing their $40 Million #SeriesB! As enterprises implement #AI, intelligent access to data has never been more important. This round — led by Insight Partners, with participation from Forgepoint Capital, GTM Capital, and S3 Ventures — will accelerate innovation and adoption of DataBahn's agentic data control plane for security and enterprise applications. We're proud to once again back co-founders Nanda Santhana, CEO, and Nithya Nareshkumar, President, as they continue building the intelligent data foundation for 🖥️ #EnterpriseAI.
For thirty years, we have been obsessed with moving data. We believe the next decade belongs to making it intelligent. Today, that belief has $40 million behind it 🚀 We've closed our Series B, led by Insight Partners, with Forgepoint Capital, GTM Capital, and S3 Ventures all returning. That takes our total funding to $59 million. One year after our Series A: → 400% revenue growth → 180% net revenue retention → Zero customer churn This round accelerates the agentic data control plane, making enterprise data work for applications and AI alike. Data in motion becomes intelligence in action.

🎊 Congratulations to Buildforce on closing their $10 Million #SeriesA! This round will accelerate Buildforce's national expansion and continued investment in its technology platform, which connects skilled electricians with commercial and industrial contractors. We're excited to back CEO Moody Heard and COO Vu Brown again as they continue addressing one of the country's fastest-growing workforce needs alongside Saepio Capital, Blue Heron Capital, Revolution's Rise of the Rest Seed Fund, and Chicago Ventures.
⚡️ I'm excited to announce the close of our $10M Series A today! This financing marks many years of sustained effort against our company mission. To that end I have to shoutout the entire Buildforce team, and in particular our leaders Vu Brown, Mark Di Marco, and Isaiah West for getting us to where we are today. I also have to thank the community of tens of thousands of electricians and electrical contractors who have come together to form the largest dedicated electrician job network in the US. This network creates serious value across the US economy everyday, and we're honored the Buildforce platform can help facilitate that. We're fortunate to have several new strategic individual investors joining us through our lead investor Saepio Capital from our hometown Houston, TX. We're excited also to welcome new investor Blue Heron Capital out of Richmond, VA to the table. This is in addition to existing investors Revolution's Rise of the Rest Seed Fund, S3 Ventures, and Chicago Ventures, along with several other long-time investors. https://lnkd.in/gnNtXZqJ

🎉 We're proud to share we participated in Vendelux's $50M #SeriesB! The value of in-person events is on the rise, but #marketing and #sales teams still lack reliable data to identify which events to attend and evaluate ROI. Vendelux closes this gap with an AI platform on top of a proprietary dataset covering 250,000+ global events and 25M+ predicted attendees, finally enabling data-driven event and conference planning. More than 50,000 marketers across 250+ customers — including Ramp, ElevenLabs, Glean, GitLab, Docusign, and Intel — use Vendelux to make event strategy data-driven. 🦾 Congratulations to co-founders Alex Reynolds and R.

Gainsight went from losing hours after every customer call to 3x more closed-won dollars per SE hour — and with Opine as their single source of truth, presales, leadership, and the product team are now all aligned. Learn more about their implementation with Opine 👇
David Greene runs solutions consulting at Gainsight (he's been our product owner there since day one and is a visionary on SE process). When Dave came to us, his SEs were losing hours after every customer call to updating their old presales management solution, and the deals always moved faster than the data entry with almost zero leverage gained from AI or automation. Not to mention the handoff docs and briefs they built by hand for every opportunity, the time leaders spent catching up on the status of opportunities, and the difficulty of getting real-time reporting on pipeline. He wanted his team spending time with prospects and it was going into manual work instead. After implementing Opine Gainsight's team has been seeing the following results: * 3x more closed-won dollars per SE hour * 10% higher POC win rate * 9 days off the average sales cycle The most exciting part to me is the entire sales team including leadership now use Opine as a source of truth to check deal status. Gainsight's product team is also using Opine to get full visibility into the missing features that are blocking deals and the revenue impact for each. We're finding we have the best opportunity context in every org, and now customers are pulling our context into other systems via our MCP. Read about Gainsight's Opine implementation in detail. They are the original legends of customer obsession. The full case study is in the comments!
