Happenstance vs Affinity

Affinity is bought by a firm, by the seat, on an annual contract. Happenstance is opened by a person, free, over the accounts they connect.

By Jerry Feng, Growth at Happenstance. Updated September 1, 2026.

The short version

Affinity, if you're buying the CRM a private capital firm runs its deals on; Happenstance, if you want the people search on its own, over the accounts one person or a pooled group connects, free. Affinity captures the whole firm's email and calendar into one permissioned graph, scores relationships, runs deal pipelines and enriches records from PitchBook, Preqin and Grata, from $2,000 per user per year with no free tier and no self-serve signup. Happenstance searches seven connected sources including LinkedIn, Twitter and Instagram and answers plain-English questions. A fund runs both: Affinity for the record, Happenstance for the search.

Affinity details from affinity.co public pages, including its pricing page and its relationship intelligence page.

Choose Happenstance if

  • You want to search who you know without a contract, a seat or a rollout
  • The paths that matter run through personal LinkedIn, Twitter, Instagram and Google Contacts, not firm email
  • You're an angel, a solo GP, a scout, a founder or an operator, with no firm to buy for you
  • The fund, its scouts and its portfolio should share one searchable network at no cost
  • You want the answer inside ChatGPT, Claude or your own code

Consider Affinity only if

  • The firm needs a system of record: deal objects, stages, notes, reminders and reporting
  • Every seat's email and calendar should be captured automatically and permissioned firm-wide
  • PitchBook, Preqin, Grata and Crunchbase data belongs on the company record
  • Procurement requires SSO, fund-level permissions and custom data retention
  • A seat price you can budget before the first sales call matters more than a negotiated one

What each one costs and what it covers

Affinity publishes its prices, which is rare in private capital software. The CRM workflow rows are where a system of record earns its seat price.

Whose network is it: the firm's, or yours

Affinity made one decision that shapes everything else: the firm is the unit. Every licensed seat's email and calendar flows into one permissioned graph, which is why it can claim 25B+ emails and calendar events captured and 130B+ structured relationships across 3,300+ firms. The record survives the analyst who leaves, and a new associate inherits a live map of who the firm can reach. For a fund, that's the right asset to build.

It's also an asset the fund owns. Your searchable network is a benefit of your seat, and it ends with the seat: change firms, and the map you spent four years feeding stays behind. Meanwhile the half of your reach that never touched a firm address, the founders you follow, the operators in your Google Contacts, the college friend now running corp dev somewhere, was never in it to begin with. Affinity advertises no personal or social source; its route past captured activity is enrichment databases and inferred network connections on Scale and up.

Happenstance is keyed to the person. You connect your own accounts, seven of them, work and personal, and the graph is built from what those accounts recorded: who wrote back, who sat in the meeting, who you follow, who's in your Google Contacts. It moves with you between jobs because it was never the employer's. When a fund wants the collective version, a group pools every member without buying anyone a seat, and each person's connections stay visible only to them, their friends and their groups.

Affinity has AI chat, and it answers from the CRM

Affinity is not behind on AI. AI Chat, the notetaker, the MCP server and the Ascend agents for meeting prep, warm intros and data updates all shipped by mid-2026, and Ascend runs inside Affinity or from Claude and ChatGPT. Two things bound what those agents can say. They start at the $2,300 Scale tier, so the natural-language layer isn't in the cheapest seat. And they answer from the CRM, which means the firm's captured activity plus the enrichment the fund pays for. An agent can't find a path that was never recorded.

Happenstance is a question box. "Which of my connections have raised a seed round since January?" "Who in our group knows a partner at Benchmark?" "Who do I know who has hired a VP of Sales at a Series B?" It returns ranked people with the introducer named and the tie shown under each, and the question costs nothing to ask because the free plan is the whole product.

Who in our group can introduce me to a partner at Benchmark?

An example of the answer this question returns. The people and the counts are illustrative; what a search returns depends on the accounts each person has connected.The scope line matters: the search ran over a group, so each path is a member's own relationship with the partner, pooled without anyone buying a seat.

500,000+ people use it, and none of them ran an implementation project to get there.

Affinity costs $2,000 a seat, and only firms can buy it

Affinity's published entry point is $2,000 per user per year, rising to $2,300 for Scale, which is where AI Chat, the notetaker, the Ascend agents and the MCP server live, and $2,700 for Advanced, which adds the enrichment sources. Enterprise is custom. Every tier goes through sales, and there's no free tier and no self-serve signup, so the price you pay is a negotiation and the thing you buy is an implementation.

For a ten-partner fund putting the whole investment team on Scale, that is $23,000 a year before the ops seats. Firms pay it, and for a system of record it's defensible.

The people it excludes are the interesting part. Someone writing $25,000 angel checks, or a partner-of-one. A scout with a carry agreement and no email address at the fund. An operator who fields three introduction requests a week. A founder in the middle of a seed. None of them has a procurement department, and Affinity has nothing to sell them. Happenstance costs nothing for all of it, and Pro at $30 a month, or $24 billed yearly, raises the usage limits. See how investors use it.

Where Affinity wins outright

The pipeline. Deal objects, stages, notes, reminders and reporting across the fund are the CRM's. If the fund does not have a system of record, that's the purchase to make first, and the comparison to run is Affinity against 4Degrees or DealCloud.

Capture nobody has to agree to. Connecting an account in Happenstance is a choice each person makes. A licensed Affinity seat reports its activity to the firm by default, which is what a compliance team wants, and a firm whose mandate is capture without consent gets it there.

Enrichment on the record. PitchBook, Preqin, Grata and Crunchbase fields sitting on the company page next to the stage, with company growth insights and industry data, are worth more than a search result when the job is portfolio monitoring.

Enterprise controls. SSO, fund-level permissions, custom data retention and a dedicated implementation team are on Affinity's Enterprise tier, and some firms can't buy software without them.

Adding Happenstance to a firm that already runs Affinity

Nothing gets unwired. The deal flow stays in Affinity, and so does the reporting the partners read on Monday. What sits beside it is the search: one sentence, answered from the accounts each person opted to connect, including the ones that never touched the firm domain. There is no integration between the two, and there doesn't need to be. You ask, you get the introduction, you log the outcome where you always logged it.

The cost of trying it is zero. One partner connects their accounts and asks the question they asked the CRM last week. If the answer is better, the rest of the team joins a group. If it is not, nothing was spent and nothing was migrated.

The people a seat cannot cover. Scouts, venture partners, portfolio founders, angels who co-invest, alumni of the fund. A group holds all of them without a seat, and it is where the fund's reach stops looking like its headcount. Start with your own accounts and add the group after.

Happenstance is by far the best social network search I have ever seen.

What Happenstance can see

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 Affinity?

Affinity is a CRM for private capital firms: it captures the firm's email and calendar, scores relationship strength, tracks deals through a pipeline and enriches company records from PitchBook, Preqin, Grata and 40+ other sources. Happenstance is people search: seven connected sources per person, plain-English questions, warm paths ranked by relationship strength, free. One is a system of record for a firm, the other is a search box for a person or a group.

Is Affinity a CRM or a relationship intelligence platform?

It sells itself as the AI-first private capital CRM, and the relationship intelligence comes out of the same captured activity: emails and meetings across the firm, scored by recency and frequency. The intelligence is a product of the CRM, and you get it by adopting the CRM. Happenstance sells the intelligence with no system of record attached, which is why there's nothing to administer and nothing to migrate.

Can Happenstance replace Affinity?

It replaces the searching: the same question, asked across each person's own accounts, social and personal included, and answered without a seat. It's free to run alongside. The deal pipeline, stages, notes, reminders and reporting stay in the CRM, and a fund that needs a system of record keeps one.

Pricing

How much does Affinity cost?

Affinity publishes per-seat annual prices: Essential $2,000 per user per year, Scale $2,300, Advanced $2,700, and Enterprise on custom pricing. Every tier is sold through a sales conversation, there's no self-serve signup and there's no free tier.

Is there a free version of Affinity?

No. Every Affinity tier is an annual per-seat contract bought through sales. Happenstance is free with no credit card, and Pro is a self-serve monthly subscription.

Is Happenstance free?

Yes. The free plan is the whole product, Sidedoor included, with unlimited connected accounts, friends and groups. The limits are on chat usage and on web searches beyond your network, and Pro at $30 a month, or $24 a month billed yearly, raises them.

Firms and individuals

Does Affinity work for individuals?

It isn't built for one. Affinity is sold to private capital firms as a seat-based team product, and the value is the firm-wide graph, so there's no individual plan and nothing to buy without a firm behind you. Independent investors and operators are outside its market by design, not by oversight.

Can a firm share networks in Happenstance without buying seats?

Yes, through groups, and that is the part a per-seat CRM can't copy. Everyone in a group can search everyone else's network, sharing is mutual, and each person's connections stay visible only to them, their friends and their groups. Because a group costs nothing, the people a seat license would never cover go in it too: scouts on carry, operating partners, founders in the portfolio, LPs who take calls. The largest groups make 380,000+ people searchable.

Should a fund choosing its system of record pick Affinity or Happenstance?

Affinity, and it should compare it against 4Degrees rather than against Happenstance. A system of record needs pipelines, permissions, reporting and an implementation. The order that works is to buy the CRM for the firm, then add Happenstance for the search, because the second one is free.

Use cases

Which is better for deal sourcing?

They source from different material. Affinity surfaces paths out of the firm's captured email and calendar and enriches what it finds from PitchBook, Preqin, Grata and Crunchbase. Happenstance answers a sourcing question across every account each person connected, personal and social included, and ranks who can make the introduction. Run both: ask Happenstance first, then log the outcome in Affinity.

Which is better for a founder raising a round?

Happenstance. Affinity is the tool on the other side of the table, sold to the firms you're pitching. Your side of the problem is finding the warmest path to a partner, which is a question about your own network and your co-founders', and a free group pools a founding team with its angels and advisors.

Data, security and assistants

Which sources does each product read?

Affinity captures email and calendar activity across the whole firm and enriches it from its own data and 40+ sources including PitchBook, Preqin and Grata. Happenstance connects seven sources per person: Gmail, Outlook, Google Calendar, Google Contacts, LinkedIn, Twitter and Instagram, reads email as headers only, enriches profiles from external providers, and runs web search for people beyond your network.

Is Happenstance secure enough for a fund?

Happenstance is SOC 2 compliant and DTI Trust Level 2, reads email as headers only, never message content, and each person's connections stay visible only to them, their friends and their groups. Affinity sells SSO, fund-level permissions, custom data retention and a dedicated implementation on its Enterprise tier, and a firm whose procurement requires those buys them there.

Do Happenstance and Affinity both work with Claude and ChatGPT?

Both ship an MCP server. Affinity's is on its Scale tier and up, alongside its Ascend agents for meeting prep, warm intros and data updates. Happenstance ships a public API, an MCP server, a ChatGPT app, Claude and Claude Code integrations and a CLI, on every plan; API and MCP calls use credits.
