Affinity vs Attio: the honest comparison for VC and PE firms

The short version

Affinity is the default CRM for venture capital, private equity, and investment banking. It earns that position with relationship intelligence: it reads your firm's email and calendar history and tells you who already knows the founder you want to reach.

Attio is a flexible, AI-native CRM. It does not score relationships the way Affinity does. It gives you something else: a data model you can shape around the whole firm, AI built into every record, and a price that is a fraction of what Affinity charges.

If intro paths and deal sourcing are the entire job, Affinity is hard to beat. If your CRM needs to cover deal flow plus portfolio support, LP relations, and operations, and you do not want a five-figure annual contract, Attio is the better fit for most funds.

We work with VC and PE firms on exactly this decision, so the rest of this is written straight.

What Affinity is built for

Affinity pioneered relationship intelligence for investors. The core idea: every email and meeting your team has ever had is data. Affinity reads that data and builds a map of who in your firm has the strongest connection to any given person or company.

When you want a warm intro to a founder, Affinity tells you which partner should send it. It captures contacts and activity automatically, so the CRM stays current without anyone updating it. It pulls enrichment from premium data partners like PitchBook and Crunchbase, which matters when you are tracking funding rounds and ownership.

Roughly 45% of the top 100 VC firms use Affinity. It is the safe, established choice, and the relationship graph is genuinely hard to replicate.

What Attio is built for

Attio is a CRM built around a flexible data model. You create custom objects, define how they relate, and shape the system around how your firm actually works.

For a fund, that means the CRM is not limited to deal flow. You can model portfolio companies, LPs, the fundraising pipeline, your co-investor network, and operational work in one system, each with its own structure. Attio also builds AI into the data layer rather than bolting it on, which we will come back to.

It is fast, it is modern, and you can start on a free plan and grow into paid tiers without a sales call.

Pricing: the biggest gap

This is where the two tools separate hardest.

Affinity sells annual contracts that start around $2,000 per user per year. The median Affinity customer pays roughly $62,000 a year. A small fund with five people on an entry-level contract still lands somewhere between $12,000 and $35,000 annually.

Attio is free for up to three users. Paid plans are $29 per user per month for Plus and $59 for Pro, billed annually. A ten-person fund on Attio Pro costs about $7,000 a year. The same fund on Affinity often pays $50,000 to $70,000 more.

For a large fund, the relationship graph can justify the price. For a fund under five people, paying Affinity rates for a CRM is hard to defend.

Relationship intelligence: where Affinity wins

We are not going to pretend this gap does not exist. Affinity's relationship scoring is its real moat.

Attio syncs email and tracks interaction history, so you can see your firm's communication with any contact. What it does not do is score relationship strength algorithmically or rank intro paths automatically. You can get partway there in Attio by building custom fields and automations that track last contact, frequency, and owner. That is useful, and for many funds it is enough. It is not the same as Affinity's graph.

If your sourcing motion depends on systematically working a warm network, weigh this carefully before you switch.

Flexibility and the data model: where Attio wins

Affinity is shaped for deal flow. That focus is a strength for sourcing and a limit everywhere else. When your firm needs to track things that are not deals, you are working against the grain of the tool.

Attio lets you model anything as a first-class object. Portfolio company health, LP commitments and reporting, talent networks you share with founders, fund operations: all of it can live in one structured system instead of a spreadsheet sitting next to the CRM.

For a fund that wants one source of truth across the whole firm, not just the deal pipeline, this is the deciding factor.

AI

Both tools have AI. They take different shapes.

Affinity uses AI mostly to keep the relationship graph current and to enrich records.

Attio builds AI into the data model. AI attributes are custom fields that fill themselves: a field that summarizes a company, classifies it into a tier, or runs a web research agent to pull funding stage and headcount from outside sources. Call intelligence joins meetings, transcribes them, and writes the results back into records. AI workflow steps let automations classify and route records without a human.

For a fund, that means an analyst can stop doing the manual research and data entry that the CRM can now do on its own.

When a fund should switch

Move to Attio when:

• The CRM needs to cover more than deal sourcing
• The Affinity renewal is large and the team is small
• You want portfolio, LP, and operational work modeled in one system
• You want AI doing research and data entry inside the CRM
• You want to redesign rather than carry forward years of CRM debt

Stay on Affinity when:

• Warm-intro sourcing is the core of how you win deals
• The relationship graph alone justifies the contract
• Premium funding-data enrichment is non-negotiable

How we handle an Affinity to Attio migration

A migration is not an export and an import. The real work is deciding what to keep, what to clean up, and what to redesign.

For a fund, that means:

• Mapping contacts, organizations, deals, and interaction history into Attio
• Rebuilding deal flow as a pipeline that matches how the firm sources and decides
• Modeling portfolio, LPs, and co-investors as their own objects
• Setting up enrichment and AI attributes so records stay current without manual work
• Recreating the reports partners actually look at
• Being honest about the relationship-intelligence gap and building the closest practical version in Attio

The goal is not to rebuild Affinity inside Attio. It is to use the move to build a CRM that fits the whole firm and costs a fraction of the renewal.
