Jan 2022
Beta launch Launch
First public beta with event ingestion, funnels, and a SQL workbench. Onboarded 40 design partners in the first week.
Our story
Built by engineers,
for engineering teams.
We got tired of analytics tools that couldn't keep up with the way modern teams ship. So we built Flux — warehouse-native, SQL-first, and designed for people who read diffs before dashboards.
Product changelog
Key milestones from beta to billions of events.
Sep 2022
Series A — $18M
Led by Craft Ventures with participation from Y Combinator and angel investors from Datadog, Figma, and Linear.
Mar 2023
1 billion events per day Milestone
Crossed the one-billion-event-per-day mark. Latency stayed under 2 seconds end-to-end, zero data loss.
Aug 2023
Session Replay launch
Pixel-perfect session replay with DOM snapshotting, network waterfall, and console logs. Privacy-first — PII masking on by default.
Jan 2024
SOC 2 Type II certification Security
Completed SOC 2 Type II audit with zero findings. Pentest reports available under NDA for enterprise customers.
Nov 2024
Warehouse-native mode
Ship events directly to your own Snowflake, BigQuery, or ClickHouse instance. Flux becomes the query and visualization layer — your warehouse stays the source of truth.
The team behind Flux
A small, distributed crew of engineers and designers who believe analytics should be fast, open, and fun to use.
Ava Chen
Co-founder & CEO
Previously staff engineer at Datadog. Built the first version of Flux in a weekend hackathon.
Marcus Reeves
Co-founder & CTO
Ex-Google, designed large-scale event pipelines processing 10B+ events/day for Ads.
Priya Kapoor
Head of Engineering
ClickHouse contributor and distributed systems nerd. Owns the ingestion pipeline.
Jonas Lindqvist
Staff Engineer
Wrote the query optimizer that makes Flux fast. Formerly at Timescale.
Sophie Moreau
Design Lead
Obsessed with making data tools feel human. Previously led product design at Linear.
David Park
Developer Experience
Maintains the SDKs, docs, and CLI. Believes every API call should be autocompleted.

Frequently asked questions
Everything you need to know about data ownership, pricing, migrations, and security.
Who owns the data I send to Flux?
You do — always. In warehouse-native mode your events never leave your infrastructure. On our managed cloud, data is encrypted at rest (AES-256) and in transit (TLS 1.3), stored in your chosen region, and deleted within 30 days of account closure.
How does pricing work?
We bill on monthly tracked users (MTUs), not event volume. That means you can fire as many events as your product needs without worrying about overages. The Hobby plan is free forever with up to 10k MTUs. Team starts at $99/mo for up to 100k MTUs.
Can I migrate from Amplitude or Mixpanel?
Yes. We provide step-by-step migration playbooks and code codemods for Amplitude, Mixpanel, Heap, and PostHog. Most teams complete the migration in under a week. Book a demo and we will build a custom migration plan for your stack.
What security certifications does Flux hold?
Flux is SOC 2 Type II certified with zero findings. We also support SAML/SSO, SCIM provisioning, audit logs, and role-based access control on the Scale plan. Pentest reports are available under NDA.
Is there a self-hosted option?
Yes. Flux can run entirely inside your VPC on Kubernetes. You get the same product with full data residency control. Contact our sales team for a license key and deployment guide.
What SDKs and integrations are available?
We ship typed SDKs for JavaScript/TypeScript, Python, Go, Ruby, Swift, and Kotlin. Server-side and client-side variants are available. We also integrate with Segment, Rudderstack, and any warehouse that speaks SQL.
