About Thunder
What Is Thunder
Thunder, at thunder.vc, is an investment bank for tech founders, and it runs on a simple premise: the people advising you should have sat in your seat. Its partners have raised, scaled and sold their own companies, and they use AI-assisted analysis plus a large network of exited founders to help you decide whether to raise debt, raise equity, recapitalize, sell, acquire, or keep building.
The firm pitches itself as an alternative to two common options: a traditional banker who mostly runs a process once you already know the answer, and a founder doing the raise alone. Thunder starts earlier. Acting as a startup fundraising advisor and an M&A advisory for startups in one, it builds a Capital Blueprint that maps what money is realistically available to your company, who is likely to provide it, and what each path costs in dilution, control and time. Sometimes that answer is to do nothing yet.
Two things matter up front. Thunder works mostly with US and UK tech and consumer companies that have already raised institutional capital and have a real transaction ahead in the next 12 to 24 months, so it isn't a fit for someone just testing an idea. And it's a bank, not software: you don't sign up and start clicking. A partner reads every application and replies within two business days.
Getting Started
- Submit the form on the site and say what you're doing: raising, exiting or investing, and a partner reviews it and replies within two business days
- Walk through a 30-minute call with a partner to map the options and what each one would require
- Agree on the target outcome and the constraints, then let the team build a Capital Blueprint covering debt, equity, recapitalization, M&A and the hold option
- Prepare the company, materials and data room, then run the process from targeted outreach through diligence and closing

Key features
The Capital Blueprint
Before any transaction, Thunder builds a Capital Blueprint that maps what is actually available to the company, who is likely to provide it, and the cost of each path in dilution, control and time. It covers debt, equity, recapitalization, M&A and the option to stay independent. The point is to decide the outcome first, so you don't spend a year on the wrong process.
A Network of Exited Founders
The firm is backed by a network of more than 6,000 post-exit founders, and it pulls in the few who have done your specific deal, sold to that acquirer, raised from that fund or survived that kind of diligence. Thunder says over 100 of them are called on directly, deal by deal, so you get advice from someone who has already solved the problem in front of you rather than a generic advisor.
AI-Assisted Analysis and Modeling
Thunder uses technology to speed up the analytical work behind a deal: financial normalization, valuation and ownership analysis, capital structure design and the counter-strategy behind a process. That's where the "tech-enabled" label comes from. It doesn't replace the partner, but it means the numbers and options get mapped faster than a spreadsheet-only shop can manage.
Debt, Equity and M&A Under One Roof
Most firms pick a lane. Thunder runs growth equity and private credit raises, recapitalizations, sell-side M&A, acquisitions and growth buyouts through the same team. So when the honest answer is a debt structure instead of the equity round you planned, that recommendation is on the table, not filtered out by whatever product the banker sells.
Prepared, Diligence-Ready Processes
A recurring theme in Thunder's work is preparation, so a round stands up to institutional diligence instead of falling apart in it. The team handles positioning, the transaction narrative, materials, data-room prep, counterparty strategy and diligence coordination, and it structures rounds so they don't get in the way of the next one.
Regulated Institutional Execution
Securities are offered through Finalis Securities LLC, a broker-dealer and member of FINRA and SIPC, which lets Thunder run institutional-grade processes rather than make introductions and hope. That gives a founder the access and paperwork of a regulated channel, and it's the piece that separates an investment bank from a well-connected advisor.
Events and the $100M Exits Community
Thunder runs private dinners, demo nights and poker nights for exited founders, venture investors and the family offices and LPs who back them, across San Francisco, Los Angeles, New York and London. It also produces the $100M Exits podcast, where Jason Kirby interviews founders and investors who have been through nine-figure outcomes. Deals have been funded and companies started in these rooms.
Pros and cons
Pros
- Partners are exited founders, so the advice comes from people who've run the same transaction themselves
- The Capital Blueprint covers debt, equity, recapitalization, M&A and the hold option before recommending one
- A network of 6,000-plus exited founders means access to people who've solved your specific deal
- Deals run through Finalis Securities LLC, a FINRA and SIPC member, so the process is institutional-grade
- Success-based fees align the firm's pay with actually closing your deal, not with running a long process
Cons
- No public price list, so you only learn the fee structure after a partner call and a scoped engagement
- Focused on US and UK tech and consumer companies past roughly $5M in revenue, which leaves out early or non-tech businesses
- No self-serve signup or free tier, so there's no way to try it before talking to a partner
- Best fit needs a real transaction within 12 to 24 months, so companies casually exploring are likely a poor match
