Attio vs Affinity for VC, PE and M&A Firms (2026)
Attio or Affinity for a fund or advisory firm? Pricing, relationship intelligence, data model and migration compared by an Elite Attio partner.
Updated November 2026
The short answer
Affinity fits firms that win deals through warm introductions and want relationship scoring and onboarding handled for them. Attio fits firms that want to model their own deals, LPs, buyers or mandates, buy without a sales call and pay less per seat. At list price, a 10-person team pays about $23,000 a year on Affinity Scale and $9,480 on Attio Pro.
We implement Attio, so we are not neutral. Below we say where Affinity is the better choice.

Where Affinity wins
Warm intro paths. Affinity maps the route to someone your team does not know directly, and Scale infers connections beyond direct email history. Attio shows who on your team has the strongest connection and stops there.
Onboarding done for you. Affinity includes import, field mapping and historical relationship data in every subscription.
Private-markets enrichment. The Advanced plan adds Dealroom and Crunchbase data and a PitchBook integration for firms that already have a PitchBook subscription.
If your partners ask “who knows this founder?” every week and the team is too big for anyone to know everyone’s network, Affinity earns its price.
Where Attio wins
The data model. You define your own objects and link them, so deals, LPs, co-investors and portfolio companies each get their own records. Verdict Capital runs a deal flow pipeline and an LP pipeline side by side in Attio, and b2venture tracks deal flow and its angel network separately.
Price and buying. There is a free plan, a Pro trial and self-serve checkout.
Building. The API, webhooks and MCP server are available on every Attio plan.
What it means for M&A boutiques
Affinity lists investment banking among its sectors. A boutique’s core records are mandates, buyers and targets, with a buyer universe for each mandate. Attio custom objects model that directly. Ashcombe moved from Excel to Attio in 10 days, and co-re.partners replaced a Notion investor database with a multi-mandate pipeline in 4 weeks.
In our view, relationship scoring matters less when most counterparties come from a researched buyer list than from the partners’ own network.
Migrating from Affinity to Attio
People, organizations, opportunities, lists, interactions, notes and files can move through the two APIs. Automations and integrations are rebuilt, calls and chats become notes, and Attio recalculates connection strength from the inboxes you connect instead of importing Affinity’s scores.
On our projects, Atlantic VC moved from Affinity to a 6-object Attio workspace in 8 days. Stride.VC took one month, including an LP and fund data model.
How to decide
Do your partners source through warm introductions every week? Choose Affinity.
Do you need your own data model for LPs, mandates or buyer lists? Choose Attio.
Will someone own the system and build workflows? Choose Attio. If nobody will, Affinity’s managed onboarding matters more.
Whichever you pick, connect every investor’s email and calendar in the first week. A relationship graph with missing partners is a graph nobody trusts.
