One platform, not three.
Analytics, identity, segmentation, automation, and email on the same event stream and the same customer record. No reverse ETL, no nightly syncs, no profile drift.
AboutBehavior first lifecycle, built for engineering teams
One pipeline from event to email.
GetFluxly is a customer data platform for engineering teams who want lifecycle email driven by what users actually do, not by lists they keep in sync by hand. Same event stream, same customer record, from track() to send.

What GetFluxly is
Three things, one event stream.
Built for developers.
A real SDK, a clean HTTP API, idempotency keys, batch endpoints, and a Console you can read like a debugger. Marketing tools live downstream of you, not above you.
Quiet, predictable, behavior first.
Real product events become the messages your users actually need. No noisy growth gimmicks, no manual list maintenance, no surprises in the audit log.
Why we're building this
The lifecycle stack is held together with duct tape.
Most teams stitch together a product analytics tool, a CRM, an ESP, a reverse ETL, and a Zapier flow. Each piece is fine on its own. The seams between them are where the actual lifecycle email work breaks down, and where the most valuable moments get lost. We're collapsing the seams.
01 / Principle
Behavior is the source of truth.
Email tools send what you tell them to send. Behavior happens in your product. We treat the event stream as canonical. Segments, profiles, and automations are all just views over it.
02 / Principle
Developers decide what gets tracked.
If your engineers don't trust the data, your marketing won't either. The SDK and API are first class. The Console is for inspecting and operating; the source of truth lives in your code.
03 / Principle
Boring infrastructure beats clever infrastructure.
We don't rebuild your data warehouse, and we don't pretend an event pipeline is a thinking machine. We do one thing: turn product events into well timed emails, and we get out of the way.
04 / Principle
Quietly confident, never loud.
No "delightful." No "powerful." No exclamation points. The product earns trust by being precise, fast, and predictable. The marketing should look the same.
A note from the founder
I'm a software engineer who got tired of broken pipelines.
I'm a software engineer by heart and by profession, the kind who genuinely enjoys fiddling with data until it actually says something useful. GetFluxly is the tool I kept wishing existed every time I had to wire one up myself.
I've spent enough time on the engineering side of data and lifecycle work to know the shape of the pain. Schemas drift, jobs fail at 3am, the “source of truth” quietly forks into three, and the people downstream lose faith in the numbers.
The right message at the right moment is a data problem, not a marketing problem.
That's the gap GetFluxly is closing. One event stream, one customer record, and automations that read the same source of truth your engineers do. No reverse ETL, no nightly syncs, no profile drift. The plumbing should be boring so the work on top of it can be interesting.
If you're an engineer, a founder, or a PM tired of stitching five tools together to send one timely email, talk to me. I read every inbound email and I'll usually get back the same day.
