Happenstance vs Connect The Dots
Both build the relationship graph from what happened between people, which makes them the two closest tools in the category. The split is how much of your network each can see, who each is built for, and what free means.

The short version
Connect The Dots, if your sales team lives in Salesforce or HubSpot and wants intro drafts routed through it; Happenstance, if you want AI people search over every account one person or a pooled group connects, free. Both build the relationship graph from things that happened (emails answered, messages exchanged) rather than from job titles. CTD connects email, LinkedIn and the CRM, drafts intro emails an executive approves, and gives a free plan of 10 AI searches a month with Professional at $20. Happenstance connects seven sources including calendar, Google Contacts, Twitter and Instagram, pools teams through free groups, and its free plan carries usage limits rather than missing features.
Connect The Dots details from ctd.ai, its pricing page and its FAQ.
Choose Happenstance if
- Your network lives in more than email and LinkedIn: meetings, Google Contacts, Twitter, Instagram
- You're one person, or a group that wants to pool networks without seats or a sales call
- You want the whole product free, with Pro only if you hit the limits
- You need to reach people outside your network too, with web search
- You want answers inside ChatGPT, Claude or your own code, included
Consider Connect The Dots only if
- Your sales team works inside Salesforce or HubSpot and wants warm paths there
- Executives will approve AI-drafted intro emails rather than write them (Ghost emails)
- Job-change tracking on accounts is part of the sales motion
- Board members, investors and advisors should join the company graph without paid seats

Both count real interactions, not guesses
Most tools that promise warm intros guess. If two people worked at the same company for three years, the tool assumes they know each other. Connect The Dots does not work that way and neither does Happenstance. Both count emails that got a reply and messages that went both ways, and Happenstance also counts time on the calendar. CTD's FAQ says it plainly: if somebody emailed you 100 times and you never replied, the score is zero.
The two products agree about what a real relationship is and differ on three things: how much of your life each graph can see, who is allowed to search it, and what it costs.
Where the paths come from: three sources versus seven
Connect The Dots connects email, LinkedIn (connections and messages) and the CRM. Happenstance connects Gmail, Outlook, Google Calendar, Google Contacts, LinkedIn, Twitter and Instagram, and runs web search for people outside the graph entirely.
The gap matters because warm paths are not spread evenly across sources. The path to a candidate is often a Twitter follow. The path to an investor is a college friend who only exists in your Google Contacts. The path to a buyer is a meeting from two years ago that never produced an email thread. A graph built from email and LinkedIn alone can't rank a path it can't see, and the strongest relationship a person has is often in one of the missing sources.
Who can introduce me to someone on the sales team at Datadog?
Example5 people on Datadog's sales team are in your network; three are account executives.

CTD reads LinkedIn messages, not just connections, and it pulls Salesforce or HubSpot into the graph. If your working network is a sales team's inbox and CRM, three sources cover it.
What free buys on each plan, and who gets to pool
CTD's free plan is $0 a month with 10 AI searches, 5 Ghost emails, 2 lists and 5 summaries. Ten searches is about one question every three days. Professional is $20 a month billed annually, $25 month-to-month and removes the caps; that undercuts Happenstance Pro at $30 a month or $24 billed yearly, so a solo user whose network fits inside email and LinkedIn and who wants the cheapest paid plan has a case for CTD.
Happenstance is free, and the free plan is the whole product, Sidedoor included, with unlimited connected accounts, friends and groups and usage limits on chat and on web searches beyond your network. Pro raises the limits.
Teams are where the two plans split hardest. Company-wide network search at CTD sits on the Business plan, custom-priced, after a sales call. On Happenstance, a group is free and unlimited: a founding team, a fund and its portfolio, a sales team and its advisors, all pooled by joining, with nobody needing a seat. The largest groups make 380,000+people searchable. CTD's external members feature (board members and investors join without paid seats) is the same idea, delivered for a sales org that has already bought Business.
Running Connect The Dots and Happenstance together
What you keep. If your sales team already runs CTD inside Salesforce or HubSpot, keep it there. Ghost emails, job-change tracking and the CRM-embedded workflow are CTD's, and a sales org that has wired its intro motion into the CRM keeps it there.
What Happenstance adds. The sources CTD doesn't connect, and the people outside a Business contract. Connect your calendar, Google Contacts, Twitter and Instagram, and ask "Who do I know at Snowflake who I have met in person?" Pool a group of founders, advisors or a whole fund without a Business contract. Reach beyond the graph with web search. All of that is on the free plan, so the second tool costs nothing to run alongside the first.
Moving over entirely makes sense when the CRM workflow was never the reason you signed up: an individual on CTD's free plan hitting the ten-search cap, or a small team that wanted pooled search and was quoted Business pricing to get it. You lose Ghost emails and job-change alerts. You gain calendar, Google Contacts, Twitter and Instagram, free groups, web search and the API. Search your network free.
“Happenstance is magical. It just found 30 connections in my friend's network who are technical and also care about language learning.”

What Happenstance reads from your accounts
Email is read as headers only. Message content and attachments never reach our servers. Yes. Your connections are searchable only by you, the friends you accept, and the groups you join, and sharing is always mutual. Your public profile shows a constellation of named people you know by default, which you can turn off anytime. We never share, sell, or use your data to train AI models. Happenstance is SOC 2 certified and DTI Trust Level 2; the full list of what is stored and for how long is on the security page.
Frequently asked questions
The difference
What's the difference between Happenstance and Connect The Dots?
Scope and buyer. Connect The Dots is a warm-intro tool built for sales teams, deployed inside Salesforce or HubSpot, with AI-drafted intro emails an executive approves and sends. Happenstance is AI search over the network one person or a pooled group has connected: seven sources, plain-English questions, free. Both score relationships from what happened between two people rather than from shared employers.
Is Connect The Dots the same kind of product as Happenstance?
Closer than any other tool in the category. Both build the graph from communications metadata and both score a relationship as two-way: CTD's FAQ says that someone who emailed you 100 times without a reply scores zero, and Happenstance ranks paths by relationship strength the same way. The split is what each graph can see and who each product is built to serve.
What are Connect The Dots' Ghost emails?
AI-drafted introduction emails written on an executive's behalf, so the executive approves and sends rather than writes. It's CTD's signature workflow feature and the free plan includes five a month. Happenstance drafts intro requests for you to send yourself.
Pricing
Is Connect The Dots cheaper than Happenstance?
On the paid individual plan, yes: CTD Professional is $20 a month billed annually, $25 month-to-month against Happenstance Pro at $30 a month or $24 billed yearly.
