Flagship product

Let an AI sales agent run your outbound for you.

Kanae is an AI sales agent that keeps your outbound moving every day — from research and outreach to reply triage and improvement. Your team just handles the initial setup and signs off on the replies that matter.

  1. 1. Build list
  2. 2. Research
  3. 3. Write
  4. 4. Reach out
  5. 5. Triage replies
  6. 6. Improve

List building, company research, individually written messages, sending, reply triage, and improvement reports. Features, pricing, and a demo are all on the dedicated product page.

TECHNOLOGY

Under the hood —she looks like one employee, but she's a team of specialized AIs.

This isn't "AI does everything." A set of specialized AIs, each with a distinct role, work together — and a human signs off before anything goes out. It's the same platform CosmoSketch runs in-house, delivered straight to you.

Research AI

Studies each company one by one across public sources, and forms a hypothesis for why they're worth reaching now.

Scoring AI

No spray-and-pray. It prioritizes prospects by fit with your offer before reaching out.

Copywriting AI

No mass-blast template. It writes a different message for each company.

Reply-triage AI

Sorts replies into "interested / question / not now" and drafts the next move for you.

Follow-up AI

Doesn't stop after one touch — it drafts follow-ups at the right intervals.

Human-review AI

Hands off to a human

Automatically flags anything a human should check before it's sent and routes it to Slack.

A human approves before anything sends

Every send recorded in an audit log

Customer data isolated and encrypted

Not boxed software — a managed SaaS where we run the operation for you.

We run it continuously on our cloud, including deliverability management (staying out of spam) and a hard spend cap. It works the same hours every day and doesn't call in sick on Mondays.

Deployment options: Standard (our cloud) / Secure (deployed inside your cloud) / Edge Runner (works on your internal network).

Proven in our own operations

We run it ourselves in a sister business (an ad-media operation) and have seen it through to replies and booked meetings. The hard numbers are disclosed in the case studies section.

Why us

Not slideware AI proposals —only technology we've run ourselves.

We try it on our own products first

CosmoSketch tests AI, UX, operating cost, and user experience through our own products and live engagements. We bring what we learn from actually running things into your operations.

We start small and ship fast

Instead of a big-bang rollout, we start from a PoC or a small improvement. In anywhere from a week to a few months, we get to something your team actually uses.

We design from inside the work

We don't just hand over a tool. We design the workflow, the team's workload, the review rules, and the improvement loop alongside it.

We design where AI ends and humans begin

We separate what AI handles, what humans must check, and where CosmoSketch stays hands-on — so the whole thing runs safely.

We feed what we learn from our own products (Micro SaaS Lab) straight back into client work.

Case studies

We start small and validate in real operations.

Ad-media business: AI-driven outbound Validated

AI-driven outbound, validated at small scale.

In our ad-media business, we validated AI-driven outbound — from list building to outreach, replies, and a booked meeting — on a small scale.

These figures are from an early validation of one specific engagement. Results vary by period, offering, and sending conditions.

Manufacturing: sourcing work and finding buyers

Proposing a PoC to help find prospective buyers, partners, and short-lead-time jobs in manufacturing.

How it works

Start small, then scale once you see results.

  1. 01

    Free consultation

    We review your challenges, goals, existing operations, target customers, and current setup.

  2. 02

    Pick a theme

    We choose the first thing to validate — for example new-customer outbound, cleaning up an existing list, overseas sales, or inbound-form outreach.

  3. 03

    Design the PoC

    We define the timeline, deliverables, KPIs, risk controls, and review flow.

  4. 04

    Build & operate

    We build the AI agents, workflows, tracking sheets, and notification/approval flows, and run them in real operations.

  5. 05

    Report & improve

    We pull the results together and recommend whether to continue, what to improve, and the next move.

  6. As results come in, move to continuous operation or expand scope. Never one-and-done — we keep the improvement loop running.

FAQ

Frequently asked questions

The questions we hear most often when companies come to CosmoSketch.

What kind of company is CosmoSketch?

A Kyoto-based AI implementation studio. We build AI agents, DX and operations improvements, and lightweight business systems end to end. Our flagship product is Kanae, an AI sales agent. We were founded in December 2022 and are based in Karasuma, Shimogyo-ku, Kyoto.

What can your flagship AI sales agent, Kanae, do?

She runs prospect-list building, company research, per-company message writing, email and inbound-form sending, reply triage, and improvement reporting — continuously, every day. A human reviews important sends before they go out, so it never becomes "AI on autopilot" and stays safe to operate.

How much does it cost?

Kanae, our AI sales agent, starts small — from a JPY 100,000 setup and JPY 50,000 per month. DX, operations improvement, and development work are quoted individually based on scope. Start with a free consultation and we'll propose the smallest sensible way to begin.

How quickly can we get started?

A small PoC (pilot) typically takes 2–4 weeks. If the scope is clearly defined, we can sometimes start even faster. There's no need to wait for a large system rollout.

Can companies outside Kyoto work with you?

Yes — we work with clients nationwide, mostly online for both consulting and operations. We also support overseas sales, such as finding overseas buyers and distributor candidates.

Can small and mid-sized companies adopt this?

We work mainly with SMBs and startups, and also with local governments and traditional industries. Because we start small and scale as results come in — rather than asking for a big upfront investment — you can begin even without a dedicated in-house IT team.

Is it safe to hand work to AI?

It's not "AI does everything." We design what AI handles, what a human checks, and where we stay hands-on. Important sends require human approval, actions and sends are recorded in an audit log, and customer data is isolated and encrypted for safe operation.

When will I hear back after reaching out?

After you submit the form, we reply within two business days. An automatic confirmation email is sent immediately. The first consultation is free, and we never push you to sign upfront.

Features, pricing, and compliance for Kanae, our AI sales agent, are covered in detail in the product page FAQ.
