The relationship layer for venture capital.
Founders ignore cold outreach. Warm introductions win deals - and grow your portfolio. Your fund's network already has warm paths to the founders you want to back, and to the customers, key hires and partners your portfolio companies need. CTD scores relationship strength across your entire firm so you always find the warm path.
The relationships exist. The firm just can't see them.
Venture firms have deal-flow tools, CRMs and market maps. None of them can answer the one question that matters: who on our team actually knows this person well enough to make an introduction?
The paths are already there
A portfolio founder's former CTO is now VP Engineering at your next target. A partner's college roommate runs BD at the acquirer you've been circling. These paths exist - your CRM doesn't know about them, and LinkedIn can't score them.
LinkedIn shows connections. CTD shows relationships.
When LinkedIn started, a connection meant something. Today the average professional has thousands - most of whom they couldn't introduce you to if they tried. CTD scores how well your people actually know someone.
Here's what most funds miss: when portfolio founders join CTD as free external members, their entire first-degree network becomes visible to the fund. Sixty founders can unlock 5M+ warm paths - turning your portfolio into your greatest sourcing advantage.
"Over ten years I've made more than 10,000 introductions for our portfolio companies. CTD makes it easy - I use it many times every week."
You have a CRM and LinkedIn. Here's what they can't do.
CTD gives you five capabilities neither tool can.
Built for the way VC firms operate
Four steps from deployment to measurable, relationship-driven outcomes.
Onboard your fund's network
Connect your firm's email server - no individual setup required. CTD maps every relationship automatically within days, then enriches it with publicly available data to surface even more warm paths.
Build the fund's Supergraph
Relationships are ranked by strength, deduplicated and made searchable across partners, advisors, portfolio founders and extended members.
Search any target
Find warm paths to founders, executives or board members at any company - instantly, across the fund's entire collective network.
Activate warm introductions
One-click intro requests go to the best-positioned connector, with timing managed to prevent overlap and connector fatigue. Track volume, conversion and outcomes.
Expand it to your portfolio companies
Invite your portfolio founders to join CTD - their networks become warm paths for the whole fund, and they get CTD to grow their own companies. The more of your portfolio that's on CTD, the more powerful everyone's network becomes.
From sourcing to recruiting
Source, diligence & win deals
See who in your fund's network knows a founding team. When firms compete for the same deal, the warmest path wins.
Turn 60 founders into 5M+ warm paths
When portfolio founders join as external members, their networks become warm paths for the entire fund - founders help founders.
Help portcos land customers
Your network already has warm paths to the decision-makers at your portfolio companies' target accounts - made visible and actionable.
Find & place top talent
Natural-language search for candidates - CROs, VPs of Sales - across the firm's entire network, with the strongest path to each.
Drive event attendance
Hosting a leaders' dinner or gathering? Find the right attendees and coordinate warm intros through the best-connected person.
Walk into LP meetings warm
See which attendees connect to your firm's network - so every conversation is warm and every meeting is intentional.
Relationship capital, doing real work
"Warm intros via CTD.ai feel natural and high-impact. We've landed meetings with executive sponsors without lifting a finger on LinkedIn outreach - it's all about the path to trust."
"It connects us to our investors' network in just one click - combining LinkedIn and email to show potential connections and reference points."
"A simple, clear path to the strongest connection to the person I'm trying to reach - it saves time and gets us access to the right people."
Common questions
We already have a CRM and deal-sourcing tools. How is this different?
Your CRM tracks companies and deals. CTD maps the people - and more importantly, who across your entire fund already knows them. It's the relationship layer between your collective network and the founders you want to reach. Deal-sourcing tools tell you what to look at; CTD tells you who can get you in the room.
And it works with your existing stack, not against it. Connect Salesforce or HubSpot and CTD enriches your CRM records with relationship intelligence - relationship scores, number of warm paths, connection strength, contact titles and more - and syncs your target accounts daily. Everything you see in CTD is exposed via the API, so you choose exactly what flows back into your CRM.
Will partners and portfolio founders actually adopt this?
CTD is built for low-friction adoption. When you roll out across the fund, admins can set up accounts without each person lifting a finger - we build everyone's graph automatically from their connected work email. From there, each person can opt in to add more: connect a personal inbox, or add their LinkedIn connections and messages.
And we've made that effortless - just drag and drop your LinkedIn export and tell Claude "upload this to CTD". Portfolio founders especially love it: they get access to the fund's broader network for hiring and sales, so adoption is a genuine win-win.
What about confidentiality? Some relationships are sensitive.
You're always in control of what you share. You can mark any connection as private so no one else can see it - or start with a fully closed network and whitelist exactly who's allowed to see your connections. And even when a connection is shared, all anyone else ever sees is the person's name, avatar and your relationship score - never the underlying emails, messages or contact details.
Does CTD read my emails?
No. By default CTD reads only your email headers - who you emailed and when, not what you wrote. That's everything we need to score your relationships.
You can optionally grant access to email bodies, but we use them only to show you the emails you've exchanged with a person (on your request) and to pull contact details from email signatures. Even then, CTD never stores email bodies on our servers.
How does relationship scoring work?
It starts with your real email activity - and it only counts when it's two-way. If someone emailed you 100 times but you never replied, that's a zero. Big group threads (you plus 100 other people) don't count either - you and the other person have to email each other directly. From there, the more you've exchanged and the more recently, the higher the score.
Upload your LinkedIn data and we layer it in: a connection on its own is a weak signal, but two-way LinkedIn messages (or real email history) bump it up.
Then we go further. Using public data, we surface relationships you'd otherwise miss - if you and someone never emailed and aren't even connected, but you worked at the same company, at the same time, in similar roles (say, both VPs), we predict you know each other. That opens up far more warm paths - with zero extra effort from you.
We have an internal tool where we consolidate all our data. Can we integrate CTD there?
Yes. Everything in CTD is exposed via our API - relationship scores, warm paths, connection strength, contact details and more - so you can pull it straight into your internal tools or data warehouse. And our team will provide resources and hands-on support to help you get the integration done.
Bring CTD to your whole portfolio
You already give founders a stack of perks. Add CTD to it: your portfolio companies get a better way to grow through warm intros - and your firm gets rewarded for bringing them on.
Your portfolio gets a deal
Promote CTD in your founder offers and we'll give you an exclusive 20% discount code for your portfolio companies - good on both Team and Business editions, so every portco can activate its own network from day one.
When both sides are on CTD, the value compounds
This is the end goal. Once your fund and your portfolio are both on CTD, your networks connect: founders open doors for the fund, the fund opens doors for founders, and every warm path becomes visible and actionable. The more of your portfolio that joins, the more powerful it gets.
