Relationship Intelligence Platforms Compared: The Best Picks for Small Teams (2026)

Somebody on your team knows the person you need to reach. You just don't know who, and finding out means a Slack message to the whole company, three "not me" replies, and an answer two days later from the one person who was on vacation.

A relationship intelligence platform is meant to answer that question in seconds. It reads the email, calendar, and LinkedIn data your team already has, works out who knows whom, and shows the warmest path to any contact.

The problem for small teams is that most of the category was built for law firms, accounting firms, and venture funds with 50 or more seats. This comparison looks at six platforms through a small-team lens: what they cost for five people, how much setup they need, and what your teammates can actually see from your inbox. Prices were checked on each vendor's site in November 2026.

Fast facts:

• Relationship intelligence platforms fall into three groups: enterprise tools for professional services (Introhive), dealmaking tools for investors (Affinity, 4Degrees), and lighter CRMs with relationship features built in (Dex, folk, Attio).

• Only three of the six publish full prices. Introhive and 4Degrees are quote-only, and Affinity lists annual per-seat prices but no trial.

• For a 5-person team, a year costs about $1,440 on folk Standard, $2,400 on Dex for Teams, and $10,000 on Affinity Essential.

• The deciding question for most small teams isn't features. It's privacy: who sees what from each person's inbox.

What a relationship intelligence platform does

Strip away the marketing and every platform in this category does four things:

1. It captures interactions automatically. The platform connects to each person's email and calendar (and sometimes LinkedIn) and logs who talked to whom, and when. Nobody types it in.

2. It builds a shared map by merging everyone's contacts into one view, so a search for a company shows every teammate with a connection there.

3. It scores or ranks relationships. Some tools assign a strength score. Others just show recency and frequency and let you judge.

4. It points you to the warm path. The output that matters is "Priya knows their CFO and emailed her last week," which turns a cold email into a warm introduction.

If you want the longer explanation, our guide to what relationship intelligence is covers the concept from the ground up. This post assumes you already know you want one and are deciding which.

The 6 platforms at a glance

What a 5-person team pays

Per-seat prices hide how different these tools are once you multiply them out. Here's a year for five people on each published plan.

A small team can run Attio Free at $0 if it has three people or fewer. 4Degrees and Introhive don't publish prices, so we left them out rather than guess.

Affinity costs roughly four times as much as the lighter tools, and it's worth that to a fund whose whole business is sourcing deals through its network. For a 6-person agency, a recruiting firm, or a small foundation, it's hard to justify.

1. Dex for Teams: best for teams that run on relationships, not pipelines

Dex for Teams is built around one question: who on our team knows this person, and what's the history? Each member keeps their own private Dex, and the team adds a shared workspace on top. People choose which accounts the workspace can see and which contacts and groups go into it.

Kevin Sun, co-founder of Dex, walks through the team workspace in this short overview:

A search for a person or company returns every teammate with a connection, when they last spoke, and a single timeline of emails, meetings, and notes from everyone who has worked that relationship. LinkedIn sync runs per member and refreshes the workspace about every two days.

The privacy model is the part small teams tend to care about most. Each person decides whether the workspace sees only email subject lines and metadata, or full content. Notes can be shared or kept private. Owner, admin, member, and viewer roles control who can edit.

Dex also brings the personal side most team tools skip: keep-in-touch reminders that can be shared or personal, and a Dex MCP server that lets the team ask an AI assistant "who on our team knows anyone at Northwind Labs?"

Price: $40 per user per month, billed monthly. The Team plan adds CRM integrations, SAML SSO, and team billing on top of everything in Dex Professional.

Watch out for: there are no deal stages or forecasts. Dex says teams that need a pipeline can run it next to their sales CRM.

Best for: venture firms, recruiting firms, foundations, agencies, and founder-led teams of 2 to 20 people that want a relationship-first CRM for small teams.

2. folk: best for small teams that also do outreach

folk is a lightweight CRM with relationship intelligence listed on every plan, plus pipelines, email campaigns, and contact enrichment. It syncs email, calendar, and WhatsApp, and it has a LinkedIn extension.

One detail matters for team visibility. On Standard, folk shares only the last 30 interactions with a contact across the team. Full interaction history needs Premium.

Price: Standard $24 per member per month on annual billing ($30 monthly), Premium $48 ($60 monthly). 14-day trial, no card.

Best for: small sales or partnerships teams that want relationship context and outreach in one tool. See our Dex vs folk comparison for a closer look.

3. Attio: best for startups that want to build their own CRM

Attio syncs email and calendar, enriches records automatically, and lists "connection strength" as an enrichment feature. Its real appeal is flexibility: you design your own objects and workflows, so it can be a relationship tool, a sales CRM, or both.

That flexibility is also the cost. Someone on the team has to set it up and maintain it, and the stronger AI and call features sit on Pro.

Price: Free for up to 3 seats, Plus $35 per seat per month on annual billing (up to 10 seats), Pro $79. 14-day Pro trial.

Best for: technical startup teams that want one system for relationships and deals. Our Dex vs Attio comparison goes through the trade-offs.

4. Affinity: best for venture and private capital firms

Affinity is the best-known relationship intelligence platform in private capital. All tiers capture email and calendar activity automatically and include relationship scoring and the warmest path to any contact. Higher tiers add a notetaker, AI agents, inferred connections, and data from PitchBook, Dealroom, and Crunchbase.

It's a strong product with a price to match, and the Affinity pricing page lists no free trial.

Price: Essential $2,000 per user per year, Scale $2,300, Advanced $2,700, Enterprise custom.

Best for: funds and dealmaking teams where deal flow tracking is the core job.

5. 4Degrees: best for dealmakers who want a guided rollout

4Degrees targets venture capital, private equity, investment banking, corporate development, consulting, and commercial real estate. It focuses on finding warm introductions and tracking deals, and it charges per user per month. Pricing is by request only.

Best for: small investment or advisory firms that want a vendor-led setup and don't mind a sales call to get a number.

6. Introhive: best for professional services firms

Introhive sells a relationship intelligence platform with modules for data automation, data quality, and contact management. It targets legal, accounting, consulting, and built-environment firms and maps who knows whom across the firm, flags churn risk, and finds cross-sell paths. Pricing isn't public.

Best for: partner-led firms that already run a large CRM and want relationship data fed into it. For a 10-person team it's likely more platform than you need.

How to choose a relationship intelligence platform for a small team

Use these questions in order. Most teams have their answer by the third one.

• Do you need deal stages? If yes, look at folk, Attio, or Affinity. If your work is about people rather than a pipeline (intros, hiring, fundraising, grant-making), Dex is the more focused fit.

• What can teammates see? Ask each vendor to show you the exact settings. If your team includes people who'll refuse to share their inbox, pick a tool where each person controls it.

• Who'll set it up? Attio rewards an owner who likes building systems. Dex and folk work out of the box.

• What's the real annual cost? Multiply by seats and by 12. A $40 seat and a $2,000-per-year seat are not in the same budget.

• Does it fit your AI tools? Dex, Affinity, and Introhive all now offer MCP servers, so your team's network can be queried from an AI assistant.

Who this isn't for

If you're a solo operator, you don't need a team platform or any relationship intelligence software built for groups. A personal CRM does the same job for one network at a lower price. And if you're a 200-person firm with a Salesforce rollout and a compliance team, the enterprise vendors (Introhive, Affinity Enterprise) were built for you, and the tools at the top of this list will feel light.

FAQ

What is a relationship intelligence platform?

It's software that connects to your team's email, calendar, and contact data, works out who knows whom, and shows the strongest path to any person or company. It replaces asking around the office.

How much does relationship intelligence software cost?

For small teams, published prices run from free (Attio, up to 3 seats) to about $40 per user per month (Dex for Teams). Affinity starts at $2,000 per user per year. Introhive and 4Degrees quote on request.

Is a relationship intelligence platform the same as a CRM?

Not quite. A traditional CRM tracks deals you enter by hand. A relationship intelligence platform captures interactions automatically and focuses on connections. Many tools now do both. We explain the difference in relationship intelligence CRM vs traditional CRM.

Can my teammates read my emails?

It depends on the tool and the settings. In Dex for Teams, each person chooses whether the workspace sees just subject lines and metadata or full content, and nothing from a personal Dex is shared unless that person adds it.

What's the best relationship intelligence platform for a VC firm?

Affinity is the category leader for funds that track deal flow. Smaller firms that care more about warm introductions than pipeline tracking often find Dex for Teams covers what they need at a fraction of the cost.

Do I need a big team to get value from one?

No. Two or three people with overlapping networks already get value, because every shared contact saves a round of "do you know anyone at...?" messages.

The bottom line

The best relationship intelligence platform for a small team is usually not the biggest one. Affinity, 4Degrees, and Introhive are built for firms with dedicated ops staff and five-figure software budgets. folk and Attio are good picks if you also want pipelines. If your team's work is about people (finding warm introductions, keeping in touch, and knowing who talked to whom), Dex for Teams covers that for $40 a seat with privacy each person controls.
