👋 Hey Product Hunt!

I'm Jason Kirby, a serial entrepreneur who's sold 4 companies, including my tech company, LiquidSky, to Walmart. After experiencing firsthand the frustration of raising capital and selling my company, we’ve transacted over $200m as a firm. I know what it takes to get a good deal done. I built Thunder to be the platform I wish I had to raise capital and to guide founders through the most transformational transactions of their lives, whether it's raising debt or equity or selling/buying companies.

I'm excited to launch our latest tool to help founders navigate their capital options. Some should start with venture capital, some are better for private equity.

Our launch today allows you to input your company details, and our AI will suggest investors that are statistically more likely to invest in your company based on your specific situation.

We have over 9,415 firms ranging from Venture Capital & Private Equity. No other platform does the homework for you on whom you should be building relationships with to get a transaction done.

Thunder is the tool I wish I had. It takes the pain out of chasing the wrong investors by matching you with people who are actually looking for companies like yours. No more zombie funds, no more shots in the dark.

🎯 What makes Thunder different
• Our database of 9,415 active investors (VCs, PEs)
• AI-powered compatibility scoring that shows who's likely to respond
• Download contact information and find portfolio founders who can introduce you
• Benchmark against funded companies to know if you're VC-ready

💭 But here are some quick hard truths about fundraising:
• Just cause you match with an investor, doesn't mean they'll invest. Remember that in the world of private investments, relationships and access are what gets deals done. We just make it easier to know who you need to know and that's half the battle.
• A list of leads doesn't contact itself. You need to use tools like The Swarm (special discount for our Premium users, $2,400 in savings) and LinkedIn to map warm intros to your target investors.
• You need to be building a company that's investable. Traction is key, so are your metrics. If you're too early for traction, but are working on something big, then you need to lean on your team’s background or have an edge in your market unique to your business. Without these elements, any attempts to woo investors will fall flat.

Easy to use, clean interface and fast results. One of the best apps for this use case I have tried in a while.

I had the chance to work with Jason and the Thunder.vc team in the past, and the experience was phenomenal. From the very first interaction, it was clear they truly understand what founders need—not just pitch decks and intros, but real support that moves the needle.
What stood out the most was how fast and focused everything was. No fluff, no wasted time—just high-signal advice, well-matched investor connections, and a platform that actually helps you get momentum when you need it most. The process felt thoughtful and founder-friendly every step of the way.
If you’re raising or thinking about it, I can’t recommend Thunder.vc enough. Jason’s built something really special here.

I can absolutely see myself using this in the near future — it’s such a well-thought-out idea and feels like a total win-win-win for everyone involved.

Wishing you an amazing launch and tons of well-deserved traction ahead. I’ll definitely be following your journey and cheering you on!

Austria feels like a dream wrapped in mountains and music.
Every moment here sings to the soul.

🚀 Love this concept. As a founder who's spent hours pitching to the wrong VCs, I know how painful the spray-and-pray approach can be. Filtering by compatibility and eliminating zombie funds is exactly what the ecosystem needs. Congrats on the launch,

Hi @jason_kirby3 congratulations on the launch! I was exploring the app and came across something that might be a bug. When I select a date in the "Target Close Date" field, for example, May 19, 2025, it displays a different date, like 06/21/2025. Just mentioning it in case it's not the intended behavior.

Congrats on the new product—sounds like an exciting launch and something that could be super helpful for startups across the board!

Love how Thunder flips the script—less “spray and pray,” more targeted action. Quick q: how are you keeping investor data fresh? With 9k+ firms, I imagine recency is everything in this game.

This tool looks to be super useful for companies that are not pure software plays. For example, my distributed-manufacturing marketplace monetizes idle time on manufacturing assets to produce cabinetry in a shortened supply chain, something a PE investor or FO could be more comfortable analyzing.

As someone who’s gone through the fundraising maze, I know how much time gets wasted chasing the wrong investors or falling into the endless cycle of cold outreach. Thunder flips that on its head. The investor compatibility scoring is especially helpful. Plus the ability to download contacts and map potential warm intros is huge win

Amazing - LFG Jason! Thunder is a smart solution to one of the biggest challenges a founder faces: fundraising. Congrats on the launch.

Hey @jason_kirby3 and thunder team! Congratulation for this amazing product and for the launch!
This is a great tool for early-stage startups. I’m also building a SaaS aimed at helping founders streamline their processes, so it’s awesome to see others working on the same direction!

Hey Product Hunt!


I am Ian McLoughlin https://www.linkedin.com/in/ian-mcloughlin/ Founder of www.stim.io. We would be nowhere without Thunder! Thunder has helped introduce us to investors and survive & thrive in what has been a very tough investor market these past 5 years.

As an angel investor that sticks with real estate and private equity, I'm excited to see a platform offering private equity options for companies and investors. Full disclosure my only early stage investment has been in Thunder and it's great to see it paying off today

@jason_kirby3 - Congrats, I'll be sure to share this around! Super stoked for you!
