Build vs Buy: How Founders Should Think Like Corp Dev

Most founders are simultaneously Head of Product and Head of Corp Dev, whether they know it or not. Bigger companies have dedicated teams to run that push-pull — product scopes the roadmap, corp dev hunts for shortcuts, and they pressure-test each other's blind spots every month. You don't have that luxury, but you still need that tension.

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." They're not buying optionality — they're buying clock speed.

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

When 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. Most startups are still getting their house in order.

Consider 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

Meanwhile, an acquirer with an established team could buy a similar feature and have it live before 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 the Corp Dev vs Product Tension Solo

In larger companies, the build-vs-buy relationship has real structure. Recreating it as a solo operator takes process, not politics.

• Annual roadmap alignment — corp dev and product map out build/buy/partner bets together
• Monthly syncs — trading 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

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 on the roadmap?
• 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

The filter keeps decisions from drifting into gut instinct.

• 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

Ask what you'd pay to acquire this feature today, what it's worth, and what happens if someone else ships it first. That framing cuts through the usual roadmap optimism.

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 was sound: 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 have been chasing. The lesson is not that building was wrong — it's that 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 no choice. 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 contract. Overnight, his company locked in both distribution and revenue.

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

When an acquisition skips an entire sales cycle or wins a channel outright, better tech is beside the point. What you need is 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 — niche infrastructure, proprietary data, GTM traction — that scarcity has real pricing power right now. 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

Every significant roadmap item deserves three direct questions before you commit resources to it.

• 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, then compare that pace to the acquirers circling your space

Then ask the hardest question of all: 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

Data from Carta reinforces a related point: founders at the seed stage should spend less time sweating valuation and more time thinking about who they're partnering with. 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 market is genuinely messy.

The same logic applies to build-vs-buy decisions: pick the partner or path that moves the business, keep your next milestone clearing the current baseline, stay default alive, and stop benchmarking against outliers.

The Bottom Line

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 goes to your dev team or a banker, decides whether you win on your roadmap or someone else's. Think like the founder. Think like the buyer. Think like both sides of the table at once.
