AI email sales manager for SaaS trials

Turn stalled trials into paying users.

Your AI sales manager emails every trial user who gets stuck, answers their replies, removes the blocker with one useful action — and hands the thread to you when a human is needed.

  • Personal emails, not drips
  • Sent from your domain
  • Users just hit reply
  • Your name, your voice

Built from the assistant that already talks to users of our own products.

Hi Maria — I noticed you created an account but haven't set up a lead feed yet. What kind of clients are you looking for? Reply to this email and I'll build the first feed for you.

Honestly I got stuck on the filters. We sell bookkeeping to small agencies in Berlin.

The problem

Half your trials quit before they see the value.

~37%average user activation rate in SaaS1

Drip emails talk at users. They don't read replies, they can't set anything up, and they keep sending after the user has left. You don't have time to write to every signup yourself.

The users who do reply are your best leads — and they wait hours or days for an answer.

How it works

One playbook. One useful action. A human when it counts.

  1. 01

    Spot the stall

    Send us two events — "trial started" and "first result". When a user stops before the first result, your AI assistant emails them from your domain, in your voice.

  2. 02

    Remove the blocker

    The user simply replies to the email. The assistant reads the reply, answers from your docs, and proposes one useful action — set something up, extend the trial, add credits. You approve it in one click.

  3. 03

    Hand off when it matters

    Billing, angry, or a big account? The assistant forwards the email thread to your inbox. You reply as usual — the answer goes back into the same thread.

Proof, not activity

We measure lift against a holdout group.

Reply rates look nice in a dashboard. What matters is whether more trials reach their first result and pay.

  • 1 We agree on your activation event and an observation window before we start.
  • 2 A random share of new trial accounts gets only your current onboarding.
  • 3 The report compares activation and trial-to-paid between both groups — plus complaints and your time spent.

FAQ

Questions founders ask.

Is this an AI SDR for cold email?

No. It only emails people who signed up for your product. No purchased lists, no cold outreach, no domain farms.

How do I know it works?

Every pilot runs with a holdout group: a random share of trial users get your normal onboarding only. The report compares activation and trial-to-paid between the two groups.

What do I need to connect?

A webhook with a few events (signup, first result, paid) and a short FAQ about your product. We set it up together during the pilot.

Which AI model writes the emails?

A pinned, tested model with zero data retention. Your users’ data is not used to train anything.

Is it legal in the EU and UK?

The assistant sends service and onboarding help to your registered users and discloses that it is an AI. Marketing content respects consent and opt-out rules. We help you set this up correctly.

Pilot program

We take five pilot teams this quarter.

Best fit: B2B SaaS with a self-serve trial, 100+ new trials a month, and a clear "first result" moment.
