What it actually does

An AI sales agent that finds, writes, and sends.

Overwise is an AI sales agent for B2B SaaS founders. It finds leads in your ICP across many sources, drafts each email in your voice, and sends on autopilot — with a one-click approval gate you control (new mailboxes start by reviewing every send). A lead with only a public profile becomes a one-click task you send yourself. Built for founders who'd rather ship product than chase prospects.

Multi-source discovery
Finds the buyers a single database can't.
Maps, the web, company registries, hiring signals — the long tail a single database misses. Every email verified.
Email on autopilot · everything else, a task
Email Sent automatically, with your approval

How it works

From one sentence to a booked call.

Every other outbound tool makes you bring the leads. Overwise finds them.

Subjectquick idea for flexspace's new Munich location

Hi Marlene,

Saw flexspace just opened its third location in Munich — congrats.

Filling a new space's desks in the first few months is usually the hard part. We help coworking spaces keep new desks booked from day one.

Worth a quick look? I can send a 2-minute overview — no call needed.

— Tobias

You're getting this because it looked like a fit for flexspace. Not relevant? Unsubscribe — one click, always.

The highlighted line cites a real signal Overwise found. If it can't cite one, it doesn't write it — and it waits for your one-click approval before anything sends.

Three modes

How much do you want to do yourself?

Three setups, depending on your answer. Switch any time. Use all three on the same pipeline.

Trust, not automation

Nothing goes out without you seeing it.

The AI writes from your mailbox, under your name. So you get the reasoning behind every lead, a check on every claim, and — if you want — a one-click approval before anything sends.

Built to protect your domain
  • Mailbox warm-up New mailboxes start slow — sends ramp over the first days, the first ones through review.
  • Bounce-spike auto-pause If bounces spike, sending pauses itself before your domain takes the hit.
  • SPF · DKIM · DMARC checks A misconfigured domain can't send until the records are right.
  • Unsubscribe in every email A one-click opt-out and List-Unsubscribe header, added automatically.
  • EU data residency Stored in Frankfurt. You're the data controller; Overwise is the processor.

I built Overwise because I run my own outbound for Gleap and BookingBird. It finds buyers I'd have missed and drafts in my voice — I only step in when a reply is real.

Questions

Things founders ask us.

Short answers. If something isn't here, ask us live in the app — every account gets a direct line.

An AI sales agent for B2B SaaS founders. Tell it who you sell to. It finds them, drafts outreach in your voice, sends email on autopilot — and for a lead with only a public profile, hands you a one-click drafted task you send yourself. Or just export the list.

Apollo and ZoomInfo give you a list. Instantly is a sender. Clay is a spreadsheet. Overwise is the only one that finds the lead, drafts the message in your voice, picks the right channel, and surfaces only real conversations — designed for a founder, not an SDR team.

Email is the primary engine — sent automatically with approval gates. For non-email channels, Overwise drafts the message (e.g. an Instagram DM for a lead with only a public profile) and queues it as a one-click task you send yourself and mark done. The AI doesn't auto-send on other channels, and there's no calling feature. Or run Discovery-only and just export the list.

Five minutes. Sign in, describe your ICP in a sentence, pick a mode. 14-day trial, card on file, no demo gate, no implementation fee.

No. Overwise picks up your tone from your sent folder. Drafts are short, specific, grounded in real signals. If we can't write something specific and true, we don't — we save it for you to review.

Three plans: Starter $99/mo (450 leads), Growth $279/mo (1,400 leads — most founders' sweet spot), Founder Team $649/mo (3,500 leads + custom probes). 20% off when paid annually. Seats scale with the tier (1 · up to 3 · unlimited) — no per-seat tax. Cancel anytime.

Hard stop with a banner — no surprise overage. Want to keep running? Flip on opt-in overage at $0.20/lead, capped at 2× your tier (worst case +$90 on Starter), or upgrade. Trust comes from never sending you a bill you didn't expect.

No. AI compute — Sonnet drafting, the cite-or-discard verifier, reply classification — is bundled in your subscription. The cost-per-day chip in your dashboard is a transparency artifact, not a billing line.

Yes. Public sources, consent-respecting, one-click unsubscribe in every email. Auto-suppression on "not interested." EU data residency (Frankfurt), and a DPA is available to every customer.

An AI sales agent (also called an AI SDR) is software that does the full prospecting-to-reply loop on its own: finds verified leads in your ICP, drafts each message in your voice, sends email on autopilot (or queues a one-click drafted task for a non-email channel), and surfaces only the replies that warrant a human. Different from a cold-email sender (Instantly, Lemlist), a contact database (Apollo, ZoomInfo), or an enrichment spreadsheet (Clay) — those are pieces; an AI sales agent does the whole job.

Overwise is purpose-built for founders running their own outbound: starts at $99/mo flat (vs. $90,000+ for one human SDR), seats included with your tier (no per-seat tax), EU data residency, 14-day trial with no demo gate. Other AI-SDR tools target SDR teams of 10+ and price per seat; Overwise targets the 1–3-person founder team.

Different jobs. Apollo is a contact database — it gives you a list and a sequencer. Overwise is the agent: finds leads (including outside LinkedIn, where Apollo is empty), drafts in your voice, picks the channel per lead, and only escalates real replies. If your bottleneck is contact data, use Apollo. If your bottleneck is the whole outbound loop, use Overwise.

Standalone AI-SDR tools typically cost $99–$649/month flat, versus $90,000+ fully loaded for one human SDR. Overwise: Starter $99, Growth $279, Founder Team $649 — 20% off annual, seats included with your tier, no per-seat tax, no LLM token passthrough.

Yes when (a) the data source is lawful (public business contacts), (b) Art. 13/14 transparency notice is included in the first message, (c) a one-click unsubscribe is offered. Overwise enforces all three by default. The EU AI Act Art. 50 "AI-assisted" disclosure footer is auto-injected. DPA available to every customer; EU data residency (Frankfurt).

For a 1–3-person founder team, yes — it replaces the discovery + drafting + first-touch loop, which is what a junior SDR spends 80% of their time on. It doesn't replace human closing on a call, and we don't recommend it for SDR teams of 10+.

Primary storage in EU-Central (Frankfurt); the vector index is EU-hosted too. AES-256 at rest, TLS 1.3 in transit. EU data residency by default; sub-processors (by category, with EU DPF / SCCs) documented at /security, and a current named list is available to customers in-app and on request.
