How Corp Dev and Product Teams Think About Build vs Buy

When you're the founder, you're often the Head of Product and the Head of Corp Dev, even if your LinkedIn says CEO. So you're also the one arguing with yourself:

• "We can build this in a few sprints."
• "Or we can buy it and go live before the next board meeting."

Bigger companies have dedicated teams to run that push-pull. Product scopes the roadmap. Corp dev looks for shortcuts. They meet monthly, swap notes, and pressure-test each other's blind spots.

You don't have that luxury. But you still need that tension — because the real decision isn't build vs buy. It's: who gets to the customer first?

If it's not you, it's probably someone with a cheque and a term sheet.

The 49% Signal: Speed Is the New Strategy

According to KPMG, 49% of dealmakers say their next M&A move is about "immediate or near-term synergies."

Translation: they're not buying optionality — they're buying clock speed.

This changes the rules. If your roadmap takes 12 months, and your competitor can buy their way there in six, you're not competing on product. You're competing on time.

And if your board starts seeing faster paths to revenue through someone else's asset, your "let's just build it" logic starts sounding like a delay.

Can Your Team Ship 40% Faster Than the Buyer?

BCG found that digital "champions" ship products 40% faster than legacy peers.

That's great if you're one of them. But most startups are still getting their house in order.

Take Tyler Denk at beehiiv. After raising, the team doubled in six months. The plan was to move faster — but in reality, there was onboarding chaos, process bloat, and knowledge gaps.

"No one knows anything. They don't know where anything is. They don't know what anyone does." — Tyler Denk, beehiiv

That's what growth looks like mid-sprint.

Meanwhile, someone else with an established team could acquire a similar feature and have it live by the time you've finished onboarding your newest engineer.

If your product roadmap depends on scaling your org first, you're not building — you're waiting.

Simulating Corp Dev vs Product When You're Both

In larger companies, this relationship has structure:

• Annual roadmap alignment — corp dev and product meet to map out build/buy/partner bets
• Monthly syncs — they trade intel on risks, targets, and what's moving in the market
• Constructive tension — product wants to build, corp dev wants to buy, and the debate sharpens both

You can recreate this dynamic, even solo.

1. Schedule a regular "Build vs Buy" review

Monthly or quarterly works. Pull in your management team or board if you have them. Force the zoom-out and ask:

• What features are slipping?
• What would we buy today if we had the cash?
• What's being built elsewhere that we're pretending isn't a threat?

2. Run every major roadmap item through a build-buy-partner filter

• Build if it's your moat
• Buy if it's table stakes or time-sensitive
• Partner if you can't win alone but can move faster together

3. Pressure-test your assumptions like a strategic buyer

Would you pay to acquire this feature today? What's it worth? What happens if someone else launches it before you do?

This is how you simulate the push-pull — not with politics, but with process.

When Beehiiv Bet on Build

Some bets are worth building. But they still carry risk.

Tyler Denk has said Beehiiv always intended to launch an ad network, but waited nearly two years to touch it. The reasoning: they needed infrastructure, users, and impressions first. It was the right call — but it almost wasn't. If a competitor had launched first and set the pricing norms in the category, beehiiv would've been chasing.

The lesson: even when you know it's a build, delay kills leverage.

When Courtyard and Butler Bought the Clock

Other founders choose speed because they have to.

Courtyard.io could have built their own secure logistics for luxury asset storage. Instead, founder Nicolas Le Jeune cut a deal with Brinks — fast-tracking credibility and operational maturity in a space where DIY equals death.

Patrick Butler did one better. Instead of trying to convince Monster.com to switch resume partners, he bought the company that already held the exclusive. Overnight, his company locked in distribution and revenue.

"There was never a hurdle to building it. But buying meant we could move now."

When an acquisition skips a sales cycle or wins a channel outright, you don't need better tech. You need a faster clock.

Scarcity Is a Strategy — But Only for a While

In Q1 2025, $64B in tech M&A was driven by hyperscalers hoarding AI infrastructure, compute, and talent. PwC projects Big Tech will deploy $300B+ on AI capex in a single year.

If you're holding something unique — infra, niche data, GTM traction — now is your window to price it. But wait too long, and you won't be scarce. You'll be surplus.

Once the hyperscalers have bought what they need, you're not selling gold. You're selling leftovers.

A Blunt Framework for Making the Call

Run every significant roadmap item through three questions:

• Is this core to our moat? If yes, build it and protect it.
• Is this urgent but not differentiated? Buy or partner — don't let timeline pride cost you the market.
• Can we benchmark our actual velocity? Count story points shipped last quarter. Compare that to the pace of acquirers circling your space. If you're slower, you're already behind.

Then ask the hardest question: what would a buyer pay for what you've built today? If you can't answer that, you're negotiating from ego, not data.

The Seed Stage Context

According to data from Carta, founders at the seed stage should spend less time sweating valuation and more time thinking about who they're partnering with. The market is messy — recent deals include a $12M seed for a day-old company, a priced round after five SAFEs hit the cap, and a "seed extension" bigger than the original.

The advice for founders moving from pre-seed to seed applies equally to build-vs-buy decisions: pick the partner who'll move the business, remember your next milestone has to clear today's baseline, stay default alive, and stop benchmarking against outliers.

Building keeps your cap table clean. But if your team can't ship faster than a buyer can acquire, you're not building product — you're burning time.

The next cheque you write, whether it's to your dev team or a banker, decides whether you win on your roadmap or someone else's.

Don't just think like a founder. Think like both sides of the table.
