…or, how to survive due diligence without screaming into a pillow (too often)
On January 1st, 2026, Sourcetoad was acquired by Thompson Holdings. That part’s public now, and I can say, I couldn’t have hoped for a better outcome. We landed inside an employee-owned ESOP structure, surrounded by genuinely kind, sharp, and values-aligned humans. The strategy, culture, and incentive structures are everything I had hoped to build, and now get to be part of.
But even when you end up in a great place, the road there can feel like trying to run your company during the day while being interrogated by a team of lawyers at night. In a language you don’t speak. Using documents you didn’t know existed.
There are things I’d do differently if I ever had to go through it again. And since I’d prefer you not learn these the hard way, here’s the post I wish someone had handed me before I started.
1. Learn What Working Capital Really Is
You may think working capital is just “the money in the bank to make payroll.” I did. But in M&A, working capital becomes a financial and legal Rubik’s cube, and it directly impacts your final payout.
Here’s the short version as I understand it: your acquirer wants to make sure they’re buying a business that can operate normally on day one. So they’ll calculate how much short-term capital (cash, AR, prepaid expenses) needs to be in the business at closing, and they’ll negotiate that as a target.
That number is ESTIMATED. It’s also normalized and adjusted. And if you miss the target, you may be writing a check post-close.
Working capital trues up after the deal, and it gets shaped by your business model. Services companies, SaaS companies, project-based revenue, each one complicates the math. And everyone else at the table knows this well, but even in our deal our CFO understood subtleties that NO ONE else did. So you need to know more than the basics on this one.
Takeaway:
Working capital isn’t intuitive, but it’s important. Study it, model it, and don’t assume your gut will guide you right.
2. Trust, But Verify, Every Time
You’re surrounded by experts: bankers, lawyers, accountants. This is their job. They’ve done hundreds of these. But even experts miss things. Especially when they assume you’re a typical deal.
Like Simon Sinek always says, “Ask the stupid question”. Stop the meeting and go back to that thing on page 73.
In our deal, the biggest potential errors we caught came from small misunderstandings or unclear phrasing. We were almost too embarrassed to bring them up. But those awkward questions (asked by my amazing CTO) saved real money, and avoided some serious cleanup work later.
Takeaway:
If something doesn’t make sense, say so. You might be the last person who catches it. Also, have an amazing partner if possible who is more diligent than you are.
3. Track Due Diligence Like a Real Project
If your deal is mid-size or larger, you’ll probably have a junior banker acting as project manager. If it’s smaller, congrats, you are the project manager now.
You’ll be asked for contracts from 2018, explanations of deferred revenue, SOC 2 policies, lists of vendors, screenshots of your HR system, and a notarized blood sample from your head of finance.
I think that you should treat this like a set of software dev sprints: set up a simple spreadsheet, assign owners, and check in weekly. Otherwise you’ll lose track or lose your mind.
Takeaway:
Diligence is a second full-time job. Manage it like one.
4. M&A Lawyers Are Insane (In a Good Way)
They don’t seem to sleep. They respond to 1:00 a.m. emails. And they will happily work through weekends like it’s a sport.
This is great, because if you’re running a company during the day, you’ll be doing your deal work at night. Prepare for that rhythm. Use it. And then take them out to a really nice dinner when all is said and done.
Yes, the billable hours can be terrifying. But the best lawyers are worth it, and not just for paperwork. They’re your coaches in how to behave when the stakes are high.
Takeaway:
If you find a lawyer who texts back at 11:30 p.m. with bullet points, think of nicer and nicer places to take them for dinner.
5. Get Comfortable Being Talked About While You’re in the Room
There’s a moment (probably more than one) when someone on a call will say something like:
“Let’s review the comp structure for the founder if he dies.”
And you’ll be sitting right there.
At some point in the process, you stop being the protagonist and become a line item. That’s good. It means the business can live beyond you. But it can be weird. No one tells you how surreal it is to hear strangers talking about your salary, your severance, or what happens if you vanish.
Takeaway:
You’re not the business anymore. And that’s the goal.
6. Talk Less. Prep More. Don’t Negotiate
This might be the hardest lesson for most founders, especially if they’re used to wearing all the newest hats: you are not the negotiator.
You are not there to show how clever you are, or explain how smart your team was for choosing that customer billing cadence. You are there to answer questions, briefly, and let the professionals work.
The deal room is not your turf. Your team, your advisors, trained for this game. Hopefully you’re good at running a company… which is COMPLETELY FREAKING DIFFERENT.
Takeaway:
Channel your inner witness stand. Brief answers. Don’t ramble like I did. Let the pros handle the rest.
7. You Get to Watch Pros Be Amazing
One of the unexpected joys of going through this process was simply watching people who are really good at their jobs work together.
Bankers who know the exact number of turns in your industry. Lawyers who can dissect a 200-page agreement in an hour. The team on the other side of the table who’s been through five acquisitions and knows what to look for.
As operators, we’re often too deep in the weeds to step back and admire professional excellence. This process gives you that chance if you’re not too sleep-deprived to notice. Hopefully you can apply that feeling to your customers and clients. They should feel as deeply impressed by you if you’re doing things right.
Takeaway:
Sometimes, it’s okay to just watch and be impressed.
Final Thought
Selling your company is intense and humbling. It’ll test your patience, your understanding of finance, and your ability to stay quiet on Microsoft Teams calls (even when you are begging for a Google Meet or a Zoom). But if you’ve built something real, and you surround yourself with people who know what they’re doing, it can also be one of the most meaningful transitions of your life.
And if you’re lucky, you’ll end up where I did: not just with a great outcome, but with a future you’re excited to help build.
Just don’t forget to sleep after it closes.
