— About us

We build one workspace
so you can stop
stitching five tools.

Twelve products under one bill. Broadcasts, flows, inbox, templates, AI, payments — built to talk to each other from day one.

— How we started
Origin story
Bengaluru + Berlim· shipping since 2024

In 2023, our co-founders were running a flower business out of Mumbai. Five different tools. Five different bills. Customer messages arriving at midnight in five different inboxes.

We built b2sender as the workspace we wished we had — broadcasts that read replies, flows that know the catalog, templates that get approved before you send them.

Um ano depois, o 4,218 teams envia 240 MILHÕES de mensagens por mês através dele.

— What we believe
Five operating principles
printed on every team laptop

Strong opinions,
loosely held.

i

Per-seat is wrong.

You should pay for messages your customers receive — never for chairs in your office.

ii

Tools should talk.

As transmissões lêem as respostas. Os fluxos conhecem o seu catálogo. O Analytics marca cada envio.

iii

Support is a human.

Email us, get a person inside 4 hours. Free plan included. Yes, really.

iv

Ship weekly, polish daily.

We deploy every Tuesday. Nothing fancy — we just refuse to break our promises.

v

Default to honest.

No dark patterns. No hidden tiers. No "contact sales" for the listed price. Ever.
