Venture capital deal flow: how to reach founders in your thesis areas early

Inbound selects for founders who know how fundraising works. That's a skill, but it's not the same as building something great. First-time founders outside the usual hubs, technical founders who'd rather ship than network, and operators who just left a big company often don't pitch until they have to.

When they do, the round moves fast and you are one of many. If you've known the founder for months, you are the investor who already understands the business. Outbound sourcing is how you build that position on purpose, instead of hoping the right intro lands.

A thesis like "vertical software for logistics" is a starting point, not a list. Break it into who the founders are, what they've done before and where they talk about their work. Then match each part to a channel.

Be honest about disqualifiers too: stage, geography, sectors you don't touch, and companies that are clearly already funded by a lead you'd never follow. For more on finding builders on X, read where B2B buyers are on X, the same sources work for founders.

Founders can tell in one line whether you looked at their work. Read what they've built and written before you write anything.

• The product: what it does, for whom, and how they describe the problem.
• Their background: what they did before and why that matters for this company.
• What they've posted recently: a launch, a hiring post, a strong opinion about the market.
• Fit with your thesis: is this squarely in it, or are you stretching?

If you can't find a specific reason to write, don't write yet. Add them to a list and wait for a post or launch that gives you one.

Short, specific, and about them. Say who you are, why their work caught your eye, and offer something real: a perspective, an introduction, a conversation with no deck required.

The good version earns a reply because it's clearly not sent to 500 people, and because asking for a conversation instead of a deck respects where the founder is.

Founders don't all live on one channel. Running two or three together means you reach each one where they actually pay attention.

LinkedIn

Strongest for founders who came from operator roles and for B2B companies. A short connection request or a message after a profile view works well. Keep it personal and leave out links in the first message.

X

Where many technical founders think out loud. Reply to a post with something useful before you send a DM, so your name isn't new when the message arrives. Our guide on replying before you DM covers the order.

Email

Best for founders you already have a reason to contact: past applicants, event attendees, scout referrals. Plain text, a clear subject and one question. Make it easy to say no, and honour an unsubscribe straight away.

Most founders will say they're not raising. Good. Ask what milestone would make them start, and when you should check back. Then show up at that moment with something useful.

• "Not raising for a while": note the milestone they mention and follow up when they hit it.
• "Happy to chat": book the call within days, not weeks. Interest fades when you're slow.
• No reply: one or two follow-ups with something new, like a reaction to their latest post. Then pause until there's news.
• "Not interested": thank them, stop, and record it.

When a founder says yes to a chat, move fast and make it easy. Offer a few times or a booking link, send a calendar invite and a reminder, and make sure whoever takes the call has read the whole conversation first.

Keep the first call a conversation, not a diligence session. Ask about the problem and the customers, share what you've seen in the space, and be clear about how your fund works and what happens next. Founders talk to each other, and how you treat the ones you don't invest in shapes who answers you next time.
