Meiro Pipes Integration
Connect Amplitude and Snowflake. Your behavioral data has context it's missing.
Amplitude captures what users do. Snowflake has what they're worth — deal stage, billing tier, support history. Pipes resolves identity across both and keeps the loop running in both directions.

Two teams. Same broken pipe.
You're in Amplitude. You can see feature adoption, funnel drop-off, retention curves. What you can't see is whether the users churning at step 3 are all on the free plan, or whether the power users who never converted are high-value enterprise targets sitting in your CRM.
That context is in Snowflake. Getting it into Amplitude means enriched user properties syncing back from the warehouse — account tier, deal stage, LTV estimate. But when the reverse sync runs, it maps to Amplitude users by whatever single identifier the connector is configured to use. Your CRM has those users by email. Amplitude tracked them by device_id before they logged in. The sync looks like it worked. The cohort is incomplete.
Amplitude's native Data Warehouse destination exports raw events to Snowflake. That part works. The problem is the return leg: enriched records from Snowflake back into Amplitude as user properties.
Amplitude's identity model merges anonymous device_id sessions into known user_id profiles internally — but that graph doesn't extend to Snowflake. Your enrichment model runs on CRM-keyed records. The reverse ETL connector maps warehouse rows to Amplitude users on one identifier. When the identifier in the warehouse and the identifier in Amplitude don't match — and for pre-signup or multi-device users, they often don't — properties land on the wrong profile or get dropped. Amplitude's schema validation then silently rejects anything with an unexpected type or property name. You don't find out until someone notices the cohort is smaller than it should be.
The Real Problem
Why connecting Amplitude and Snowflake still takes too many tools
Amplitude's native Data Warehouse destination covers the outbound leg — behavioral events land in Snowflake. The gaps are identity resolution across systems and the return flow: enriched Snowflake properties back into Amplitude user records for cohort targeting.
Amplitude's identity model is internal. It merges anonymous device_id sessions with authenticated user_id records as users log in — but only within Amplitude. When Snowflake holds records keyed on email from the CRM, account_id from the product database, or customer_id from billing, no connector automatically maps those to the right Amplitude user. A reverse ETL job configured to match on user_id will miss every record where the warehouse identifier is email. The result: enriched properties that appear to sync successfully but land on a subset of the intended profiles. Users who converted from anonymous sessions, users who exist in CRM but never triggered an Amplitude event, users with multiple devices — all partially or incorrectly enriched.
Amplitude's schema governance adds a second failure surface. Amplitude enforces event schemas and property types through its Data Management layer. A Snowflake VARCHAR column syncing to a property expected to be a number fails silently — Amplitude accepts the API call and drops the property. A renamed property in the warehouse breaks the mapping. Debugging means cross-referencing Amplitude's Data Quality dashboard, the reverse ETL delivery logs, and Snowflake query history with no single point of visibility.
Pipes resolves identity before data moves. It stitches device_id, user_id, email, account_id, and any other identifier into a unified profile — then maps the correct Amplitude user for every enriched record. Schema type coercion and property name validation happen in the transform layer before the API call, so mismatches surface where you can fix them, not silently inside Amplitude's ingestion pipeline.
One platform. Collect, resolve, model, activate.
Collect
Pipes connects to Amplitude via its export API and warehouse connector. Events are ingested on a scheduled or near-real-time basis — no replacement of your existing Amplitude SDK or tracking plan required.
Load & Model
Events land in your Snowflake warehouse automatically. Pipes connects directly — browse tables, map columns, model data. Your warehouse stays your source of truth.
Resolve Identity
Pipes stitches user profiles across Amplitude events and Snowflake records using deterministic matching on email, user_id, device_id, or any identifier you define. Configurable merge limits prevent false matches on shared devices. No probabilistic guesswork.
Activate
Enriched profiles and segments flow back into Amplitude via scheduled or real-time sync. Your growth team gets warehouse-enriched cohorts directly in the tool they already use — no reverse ETL vendor required.
Use case: Enriching Amplitude cohorts with commercial data from Snowflake
Your product team runs Amplitude. Every signup, feature activation, and session lands there as events. Your data team has built a Snowflake model that joins those behavioral signals with CRM data — deal stage, account tier, renewal date — and produces an enrichment score per user.
The goal: get that score into Amplitude as a user property so growth teams can build cohorts without SQL access.
Without Pipes: you write a reverse ETL job that reads the enrichment table, maps warehouse records to Amplitude user_ids, and calls Amplitude's Identify API. The mapping works for authenticated users. It breaks for users who are in Salesforce but signed up anonymously in Amplitude, users who used multiple devices before logging in, and users whose Salesforce email doesn't match their Amplitude signup email. Amplitude schema validation drops properties where types don't match, silently. The cohort your PM builds has 60% of the intended users. No one knows why.
With Pipes: the enrichment table is modeled as a source. Pipes resolves identity across device_id, user_id, email, and account_id before any data moves — the correct Amplitude profile receives the enrichment score regardless of which identifier the warehouse record carries. Type coercion and property validation run in the transform layer. The cohort has the right users.

Under the hood
Amplitude Connector
Connects to Amplitude via its export API and warehouse connector. Ingests events on a scheduled or near-real-time basis. Supports event filtering and transformation via Pipes sandbox functions. No replacement of your existing Amplitude SDK.
Snowflake Connector
Direct Snowflake connection via warehouse credentials. Browse schemas and tables, inspect columns, map identifier columns to Meiro identity types. Handles Snowflake `VARIANT` and `ARRAY` columns — common in Amplitude event exports — without a staging bucket or intermediate flattening step.
Identity Resolution
Deterministic stitching across identifier types: email, user_id, device_id, cookie. Configurable merge limits (maxIdentifiers) and priority hierarchy prevent false merges. No probabilistic matching.
Reverse ETL / Profile Sync
Scheduled exports or real-time Live Profile Sync. Push enriched profiles and audience segments back to Amplitude or any downstream destination via custom send functions.
Transform Layer
Sandboxed JavaScript functions for event transformation, filtering, and enrichment. Run inline — no external orchestrator needed.
Self-Hosted Option
Deploy on your own infrastructure for full data sovereignty. Or use Meiro Cloud. Your data never leaves your perimeter unless you want it to.
