What's possible with the CTD API

The shortest path to
every deal, hire,
and intro.

Ask Claude who you know at any company. Enrich CRM records the moment they're created. Alert your AEs when deals go cold. Source LPs, founders, and co-investors through warm paths. Integrate relationship data into your internal tools. All powered by your real relationship data.

Sales & prospecting
Board as a sales weapon
Exec Sales
Take your top 20–30 priority accounts and map which ones your board members have direct warm paths into. Walk into every board meeting with a concrete ask: "Here are the 8 deals where you can open a door — will you?"
"Here are our top 25 target accounts. Show me which ones our board members have strong connections to, and who the best connector is for each."
Prospect meeting prep
Sales
The day before a call, map every path your team has into that company — who knows who, at what level, how warm. Walk in knowing the full relationship landscape, not just the one contact who accepted your LinkedIn request.
"I have a call with Stripe tomorrow. Show me all paths our team has into their org, ranked by strength — especially anyone in Finance or Revenue leadership."
Champion tracking
Sales
Monitor when known champions at prospects or customers change jobs — catch the signal before they land somewhere new.
"Show me all champions in our network who changed jobs in the last 30 days."
ICP list prioritization
Sales
Paste in a list of target accounts and instantly rank them by relationship strength — start with the warmest doors first.
"Here are 20 accounts we're targeting this quarter. Rank them by how strong our network connections are."
Multi-threaded deal strategy
Sales
For a deal stuck with one contact, find all other paths into the account to add champions across the buying committee.
"Our deal at Workday is stalled with the IT buyer. Who else in our network knows someone in their Finance or Procurement org?"
Customer success & expansion
Expansion path scouting
Customer success
For a current customer, find warm paths into other business units or subsidiary companies to support expansion conversations.
"We're expanding inside Salesforce. Show me paths into their EMEA division — we only have US contacts today."
Churn risk early warning
Customer success
When your main contact at an account goes dark, immediately find alternative paths through your team's network before the deal slips.
"Our champion at HubSpot just went quiet. Who else on our team has connections there we could activate?"
Relationship freshness audit
Customer success Pipeline
Find high-value relationships that have gone cold — people you were active with 6-12 months ago who haven't heard from you since.
"Show me all VP+ contacts I haven't communicated with in 90 days but was active with before that."
Recruiting & talent
Warm candidate outreach
Recruiting
For a specific open role, surface candidates in your extended network with the right title — and the strongest intro path to each of them.
"We're hiring a Head of Data. Show me all Directors or VPs of Data Engineering in our network, sorted by reachability."
Alumni network sourcing
Recruiting
Find people who previously worked at a company known for great talent in your function — and who are reachable through your network today.
"Show me people who used to work at Stripe that we can reach through our network. Filter for product and engineering roles."
Events & partnerships
Speaker sourcing
Events
Planning a conference or webinar? Find high-seniority people reachable through warm intros — no cold outreach needed.
"We're putting together a fintech summit. Find me reachable C-suite contacts in fintech where we have at least a medium-strength path."
Event guest targeting
Events Sales
Hosting a dinner or field event? Identify VP+ contacts in a specific city where you have strong enough relationships to get a yes.
"We're hosting a marketing event in NY — find all VP+ marketing people in New York where we have strong relationships."
Partnership intro mapping
Partnerships
Exploring a new integration partner? Map every warm path into their BD and exec team before sending a cold form.
"We want to partner with HubSpot. Show me who on our team knows someone in their partnerships or BD org."
Investor intro routing
Exec
Find the strongest warm paths to specific VC partners or LPs — ranked by connector strength, not alphabetically.
"We're fundraising and targeting Sequoia and a16z. Show me our best paths to partners at both firms."
Pipeline & outreach ops
Super-connector discovery
Pipeline
Find the single contacts in your network who are bridges to the most target accounts — the people worth investing in most.
"Which people in my network are connectors to the most companies on our target list? Rank them."
Outreach status briefing
Pipeline
Before a weekly pipeline review, pull a summary of all active asks and ghost emails — what's pending, replied to, or stalled.
"Give me a status summary of all active ghost emails and asks. Flag anything that's been pending for more than 7 days."
Territory warm mapping
Sales Pipeline
For a new sales rep inheriting a territory, instantly map all warm paths to target accounts in their region — so day one isn't cold outreach.
"Our new AE is covering the Pacific Northwest. Show all reachable VP+ contacts at companies in Seattle and Portland."
CEO communication intel
Exec Sales
Surface every senior leader your CEO has communicated with recently — so you can map exec alignment across your pipeline at a glance.
"Show me all CEOs I've communicated with in the last 6 months."
RevOps & CRM automation
Account enrichment
RevOps
Automatically enrich every account in your CRM with CTD relationship data — total paths, strongest connectors, relationship score — so reps always know how warm an account is before they touch it.
Contact enrichment on creation
RevOps
Trigger a CTD lookup the moment a new contact is created in your CRM. Instantly attach relationship paths, mutual connections, and reachability score — before the rep even opens the record.
Stage change notifications
RevOps Sales
When an opportunity moves to a new stage, automatically notify the AE with fresh relationship paths into that account — the right intel at exactly the right moment in the deal cycle.
Lead scoring enrichment
RevOps
Add relationship reachability as a scoring dimension on inbound leads. A lead from a company where you have three strong paths should rank higher than a cold inbound from the same ICP.
Stale opportunity alerts
RevOps Pipeline
For deals that haven't moved in 30+ days, automatically surface untapped relationship paths the AE hasn't tried yet — turning a stuck deal brief into an actionable re-engagement plan.
CRM hygiene via relationship data
RevOps
Cross-reference your CRM contacts against CTD to find job changes, departed contacts, and missing stakeholders — keeping your data clean without manual research.
Venture capital
LP sourcing for your next fund
VC
Map your entire team's network against known LP profiles — family offices, endowments, fund of funds — and find the warmest intro paths before your fundraise kicks off.
"We're raising our next fund. Show me all family offices and institutional LPs in our network ranked by relationship strength, and who the best connector is for each."
Deal sourcing — find founders early
VC
Surface founders in your extended network who match your thesis before they run a process. The best deals get done before they're on everyone's radar.
"Show me all founders in our network — include second-degree connections with a strong path. Rank by how reachable they are."
Founder job change signal
VC
Track when senior operators and executives in your network make a move — the moment someone leaves a big company is often the moment they start building something new.
"Show me all CEOs and C-suite executives in our network who changed jobs in the last 6 months."
Portfolio company support
VC
When a portco needs a key hire, a customer intro, or a strategic connection — instantly find who across the fund's entire network is best placed to make it happen.
"Our portco needs a VP of Sales intro at a Series B fintech. Who across our entire fund network has a strong path to someone in that profile?"
Co-investor relationship mapping
VC
Before approaching a fund to co-invest or syndicate, map every warm path your team has to their partners — so you're not going in cold on a relationship business.
"We want to syndicate with Bessemer and Lightspeed on this deal. Show me our strongest paths to partners at both firms."
Portfolio board prep
VC
Before a portco board meeting, surface relationships the founder has across their network that the fund could activate — strategic customers, key hires, follow-on investors.
"We have a board meeting with our portco next week. Show me all paths through their founder's network to enterprise buyers in financial services."
LP & founder event targeting
VC Events
Hosting a founder dinner, LP update event, or portfolio summit? Find the highest-value people you can actually get a yes from based on real relationship strength.
"We're hosting a founder dinner in SF next month. Show me all Series A and B founders in our network in the Bay Area where we have a strong or medium path."
Reference call sourcing
VC
During diligence, find back-channel references you can reach independently — former colleagues, co-founders, or early customers who know the founder but aren't on their reference list.
"We're doing diligence on a founder. Find people in our network who worked with them previously that we could reach for a back-channel reference."
Custom workflows
The examples above are just the beginning.

Every team uses their network differently. We work directly with customers to design integrations and workflows that fit how you actually operate — whether that's a custom Claude skill, a CRM automation, a Slack bot that surfaces relationship paths on demand, or something we haven't built yet. If you have a workflow in mind, we'll help you make it real.
