How I Invest

Investment Thesis

I deploy personal capital into seed-stage founders who aim to build listed companies. Here's how I think about investing, what I look for, and how the process works.

Philosophy

Why I invest

"I want to see landscapes I couldn't see on my own — through angel investing."

After building ネットマーケティング from zero to a TSE First Section listing and a ¥13.5 billion exit to Bain Capital, I turned to angel investing full-time. My goal isn't just financial returns — it's to stand alongside founders who are building the next generation of listed companies, and to experience the journey with them.

My investment style is "Hands-if" — I'm always available when you need me, without getting in your way. The founder should run the business freely. I step in when asked: capital strategy, IPO preparation, fundraising introductions, organizational challenges.

Stage Focus

Where I invest

Primarily seed stage, with selective investments at pre-seed and Series A.

Early

Pre-seed

Even before MVP. If you have conviction about the market and a clear thesis, I'm willing to listen. This is where angels like me must step in — because most VCs won't.

Primary Focus

Seed

My sweet spot. You have early traction or a compelling prototype, and you're ready to raise your first meaningful round. This is where I write the majority of my checks.

Selective

Series A

I participate in Series A rounds when the company is a strong fit and I can co-invest alongside institutional VCs. Typically as a follow-on to an existing seed investment.

Capital Allocation

Ticket size & annual deployment

I deploy approximately ¥100M per year across 6 new investments plus follow-on capital for existing portfolio companies.

Tier 1
¥20M × 3 companies
More established startups likely to attract VC follow-on. Lower risk, proven traction.
Tier 2
¥5M × 3 companies
Rougher, higher risk/return. Where angels like me must step in because VCs won't yet.
Follow-on
~¥25M reserved
Additional capital for existing portfolio companies showing strong progress.
Annual Total
~¥100M / year
Across 6 new companies + follow-on. All from personal capital.
Sectors

Industries I focus on

Two primary thesis areas — Compound SaaS (B2B) and New-Market Platforms (B2C) — plus broad interest across IT/web verticals.

Criteria

What I look for in a startup

Six core criteria I evaluate before making an investment decision.

01 · Market

Market size > ¥100B within 5 years

I invest in large markets. If the total addressable market won't exceed ¥100 billion within five years, the ceiling is too low for a unicorn outcome.

02 · Ambition

Unicorn candidate potential

I'm looking for companies that could reach ¥100B+ valuation. This means aiming for IPO or a transformative outcome — not a modest lifestyle business.

03 · Economics

Deep resolution on unit economics

Even at seed, I want to see that you've thought deeply about LTV, CAC, payback period, and the path to profitability at scale.

04 · Position

Industry #1 potential

Can you become the dominant player in your category? I back founders who are building to win their market, not to survive in it.

05 · Go-to-Market

Sales capability (B2B) or marketing capability (B2C)

Great products don't sell themselves. For B2B, I evaluate your sales motion. For B2C, I look at user acquisition and growth strategy.

06 · Character

Founder integrity

Above all else — are you honest? Can I trust you? Investing is a long-term relationship, and character is the foundation of everything.

Founder Evaluation

What I look for in founders & teams

Beyond the business metrics, I evaluate the people behind the company.

In the CEO

Passion & enthusiasm

Does this founder burn with conviction about the problem they're solving? Passion sustains you through the inevitable dark periods.

High perspective (視座の高さ)

Can they see beyond today's challenges to the larger opportunity? Do they think at the scale of the market, not just their current product?

Ideas, vision & expertise

A unique insight into the market combined with deep domain knowledge and a compelling vision for the future.

Likability (可愛げ)

Can they attract talent, investors, and partners? The best founders have a quality that makes people want to help them succeed.

Teamwork & management ability

Solo brilliance isn't enough. Can they build and lead a team? Can they delegate, set culture, and scale beyond themselves?

In the Team

Pivot capability

Can the team recognize when something isn't working and adapt quickly? Startups rarely succeed with Plan A alone.

Bias toward action

Speed of execution matters more than perfection at seed stage. I want to see a team that ships, learns, and iterates fast.

Execution ability & GRIT

Startups are a marathon of sprints. The teams that win are the ones that keep pushing through setbacks with relentless determination.

Team-first results philosophy

Not individual heroics — can the team produce results collectively? The best startups have a culture of shared accountability.

Transparency

Not a fit

I want to be upfront about what falls outside my investment scope so we can both save time.

Business Model

Pure outsourcing / consulting

Businesses built on selling time rather than building scalable products. These can be great businesses, but they don't fit the venture return profile I seek.

Scale

Region-limited small businesses

If the business is inherently limited to a single region with no path to national or global scale, it doesn't match my thesis.

Market

Non-growth markets

I need to believe the market is expanding. Competing for share in a shrinking or stagnant market makes the math too difficult.

Intent

Short-term exit only / Not ready for investor dialogue

If you're optimizing purely for a quick flip, or not yet ready to engage in substantive discussions about your business, we're not aligned.

Process

From first contact to investment

The typical process from initial reach-out to post-investment support.

Form submission or direct contact

Submit your pitch through the website form, or reach out via Facebook Messenger. Either way works — just include your company name, stage, and a brief description.

Initial screening

I review your submission against my investment criteria. I aim to respond within 2 weeks with either a meeting invitation or feedback on why it's not a fit.

Meeting (60 minutes)

15 minutes for your pitch, 30 minutes of Q&A, and 15 minutes to discuss next steps. I prefer to understand the founder as much as the business.

Additional materials review

If the meeting goes well, I'll request additional materials — financial projections, cap table, detailed market analysis, or customer data as relevant.

Investment decision

I make decisions relatively quickly. As an individual angel, I don't have an investment committee — it's my capital and my conviction.

Contract & funding

We agree on terms (typically J-KISS or preferred stock), execute the investment agreement, and I wire the funds.

Post-investment support

"Hands-if" begins. I'm available for capital strategy, VC introductions, IPO preparation, organizational challenges, and anything else where my experience is useful.

How I think about markets & investing

Selected posts from @an0gel0 that reflect my investment thinking.

May 2024 SaaS Economics
SaaS business reality: Monthly ARPU ¥100K (low end ¥10K). To IPO you need ~¥2B revenue. You need compound SaaS or enterprise pricing to raise ARPU — otherwise the math doesn't work at scale.

Sep 2025 Market Sizing
TAM/SAM/SOM — honestly at seed stage I only listen to SOM (short-term achievable market). Show me the realistic near-term opportunity, not a fantasy trillion-yen TAM slide.

May 2024 VC Dynamics
VCs tend to invest more easily in: 地方創生 (regional revitalization), 既存産業DX (legacy industry DX), GO Global — because their LPs are regional banks, major corporations, and government funds. Understand your investor's incentives.

FAQ

Frequently asked questions

From what stage can I consult with you?
From pre-seed onwards — even before you have an MVP. If you have conviction about the market opportunity and a clear thesis, I'm happy to have a conversation. Many of my best investments started as early-stage discussions before the product existed.
Can I consult with an incomplete pitch deck?
Absolutely. You don't need a polished 30-page deck. Just share your current status — what you're building, why, and where you are. I've invested in companies that pitched me on a napkin. What matters is the thinking, not the formatting.
How long until I receive a reply?
I aim to complete initial screening within 2 weeks. If I'd like to meet, I'll suggest dates. If it's not a fit, I'll try to explain why — sometimes I can point you to other investors who might be better aligned.
Do you invest in regional or overseas startups?
My primary focus is Japan-based IT/web startups, but I'm open to discussing opportunities regardless of location. If the business has a Japan connection or if the founder wants to discuss strategy, I'm willing to talk.
Can you lead the round?
As an individual angel investor, I typically don't lead rounds in the traditional sense. However, I can coordinate with VCs and other angels to help structure larger rounds. I'm connected to 63 VCs and 20+ prominent angels.
Can you introduce me to VCs?
Yes — this is actually the #1 request from my portfolio companies. I'm connected to 63 VCs and 20+ prominent angel investors. When the timing is right, I actively bridge founders to the investors who are the best fit for their stage and sector.
