Introduction

Most startup guides are bloated or overwhelming. You don’t need a 300-page manual to start a company — you need tactical advice and practical answers, fast.

This is the guide we both wish we had at Super.com and Glean.com. We’re Henry Shi and Deedy Das. Henry founded Super.com, a $200M annual revenue startup that raised $150M in VC funding, and Deedy was on the founding team of Glean, a $X00M ARR startup with a $7B valuation, and is currently a venture capitalist at Menlo Ventures. Between us, we’ve invested in over 100 startups.

In the modern AI era of startups, we’re seeing teams run leaner than we’ve ever seen before and grow faster than we’ve ever seen before. We will soon see the first 1-person unicorn, and we’re already tracking the startups with the highest revenue per employee on the Lean AI Leaderboard, which features companies like Cursor, Midjourney, and Surge AI. This lofty goal would be impossible without the right set of tools to let founders focus on what really matters. This guide is written by founders for those founders. It’s a practical step-by-step playbook focused on launching a lean, AI-native startup in 2025.

How to use this guide

We think the best way to skim it quickly once to know what it has and then bookmark it as a reference guide for later when you’re actually in the weeds of getting your startup off the ground.

Step 1: Legal and Incorporation

Incorporate Fast — The Right Way

You’re serious about building a startup with the capacity to raise funding, attract co-founders, or otherwise give yourself headroom to grow. If that’s the case, you should incorporate as a Delaware C-Corp.

It’s the industry standard for U.S.-based startups and is typically required by most tech investors. There are tools available to make this step easy, including Stripe Atlas , Firstbase , Slash , or Clerky.

These tools handle paperwork, tax IDs, and compliance, with step-by-step instructions throughout. For ease of use and potential scalability as you grow, I recommend Stripe Atlas. If you want something fast and light to get started right away, Clerky is a good option.

Tip: Members of Microsoft Founders Hub can get a 50% discount using Stripe Atlas to incorporate.

If you want to stay lean, an LLC is a solid option. If you don’t need to raise money or are already profitable, doing so can help avoid double taxation. A 1-person AI-native company could certainly start as an S-Corp/LLC and later convert to a C-Corp to realize the 10x basis for the maximum QSBS exclusion up to $750 million.

Legal Templates

To start, you’ll want:

Otherwise, you can find reliable and reputable templates from Y-Combinator or a service like LegalZoom, and get started. These won’t be tailored to your specific needs, but if you need a simple, enforceable contract, that’s the cheapest option. It’s essential to get these in place before starting in earnest, but don’t over-lawyer at this stage. Move fast and stay agile.

Compliance

Tip: While lawyering up at this stage may seem like an uphill climb and unnecessary expense, it’s wise to run any document templates by a lawyer before you sign off. Investing a few thousand dollars in document review at this stage can save you 10 times the cost when and if you need to convert your incorporation structure down the road.

Footnote: An interesting development: Andreessen-Horowitz has decided to reincorporate in Nevada and suggests startups should make this move, too. Due to the ongoing changes to Delaware corporate law, the firm believes Nevada is a more sustainable solution going forward. I suggest you speak to a lawyer familiar with startup business structures to determine which is best for your company.

Step 2: Finance & Taxes

Separate Finances on Day One

Your first step after incorporating, ensuring legal and compliance are in place, is to open a business bank account. Many traditional banks offer startup-friendly rates and features, but modern options are specifically designed for startups. Mercury , Ramp , Brex , and Rho are good options for keeping personal and company finances distinct, offering simplified tax and bookkeeping results for later on.

Founders should also open a separate, personal business account for expenses related to the founder, such as healthcare and travel. Staying disciplined here will ultimately benefit you.

Get Tax-Savvy

Understanding your company’s — and your own — tax liability will ease the pain when it comes to the end of the year. Using a startup-friendly solution like QuickBooks , Pilot , Finta , or Kruze , you can:

Next, your 83(b) election. You’ll need to file this within 30 days of receiving your founder equity to lock in long-term capital gains tax treatments. Services like Carta or Clerky send this via email after you’ve completed the paperwork to issue stock subject to vesting. If you went with another solution, HireChore can simplify this for you.

Maximize QSBS (if applicable)

If you’re going for traditional venture scale, utilizing QSBS (Qualified Small Business Stock) can eliminate federal capital gains taxes on up to $10M in stock gains if you:

For an S-corp or LLC, it can make more sense to ignore this step while you stay lean and become profitable; otherwise, you may subject yourself to double taxation in a C-Corp. You can always convert your company into a C-corp later and realize a multiplicative basis for QSBS down the road. This can be a powerful strategy for founders, as it can increase the exemption to $750 million (10x).

Bookkeeping Tools

There’s no shortage of bookkeeping solutions for startups and small businesses. I’d rely on Haven orHireChore. These platforms help integrate your bank accounts and credit cards to categorize your expenses and revenues, and generate reports.

Equity and Cap Tables

I’d advise managing your equity cleanly from the jump. Use Carta , Cake , or Pulley to issue shares, track ownership, and prepare for fundraising.

Don’t DIY your cap table in Excel. You’ll regret it.

Step 3: Tech Stack (AI-Native and Low-Code)

Low-Code / No-Code Stack

While I’m not saying you shouldn’t have an engineer on board at the outset, modern tools can help founders with a great idea get started right away with working proofs of concept and even get launch-ready with little to no coding required.

What I’d recommend for the following:

MVPs

Speed to MVP is crucial. These tools can get you there quickly:

Domains and Hosting

Security and Compliance

Step 4: Product and Design

Lean Project Management

Avoid overcomplication at the outset. I recommend:

Stick to weekly goals or short sprints, customer-driven priorities, and ruthless focus. Don’t get bogged down in process or what-ifs.

Fast and Functional Design

I suggest:

Pixel-perfect design can come later. Focus on utility, feedback loops, and speed.

Customer Research

I’d start talking to customers as soon as you have them. Use:

Experimentation & Analytics

Some tips to make A/B testing work:

Focus on outcomes.

A/B testing helps you make more informed decisions with limited resources. It replaces guesswork with signal.

Step 5: Business Ops

Payments

Customer Success

Early on, you can keep support manual and 1:1 with your team. Email, Slack, or direct chats. Tools like Fyxer , Pylon , or even a simple n8n automation step can help streamline and collate these.

Tip: Designate someone in your founder’s group to be the quarterback on support requests and directing traffic.

As you grow, consider;

You should invest in your early users first and foremost. Their delight and word of mouth will be your most powerful and cost-effective marketing channel at this stage.

Step 6: Marketing and Growth

Secure Your Social Presence

Written Content/Inbound Marketing

Video/Images

Branding/Logos/Design

Growth Loops and Virality

Paid Marketing

Start with a clear offer and a single funnel. You can optimize delivery, but you can’t fix a broken offer. Try “Start your trial” or “See a customized demo.” Then use one destination (a landing page or signup flow), pick a metric (CAC or CPS), and then:

Step 7: Sales

Outbound Sales

Inbound

Building an inbound pipeline should focus on three things:

  1. Mapping ICP and buying signals.

  2. Training your AI tools to focus on key content to help inform the ICP.

  3. Setting up routing and booking flows.

  4. Use Piper (Qualified) to grab firmographic and intent signals, then engage.

  5. Koala agentic AI to help reps prioritize the most meaningful signals.

  6. RB2B to identify website visitors and boost leads.

CRM Tools

Step 8: Hiring (If You Must)

Should You Hire?

Thanks to the reduction in overhead and the need for fewer headcount with modern AI solutions, AI-native companies can delay hiring for longer than traditional startups. Content, support, engineering, and operations can be streamlined at these early stages. Before you hire, automate, automate, automate. Then, when it comes time to hire and fill critical roles, ensure they’re well-versed in AI, as that should be a given. Senior talent who have demonstrated their capability and are eager to learn new tools should be your priority.

When You Do Hire

Salary and Equity

Payroll and Benefits

Step 9: Fundraising

Do You Need VC Money?

AI-native companies are relatively cheap to build and scale — the infrastructure is in place to make operations lean, fast, and affordable. With a good plan and compelling product, revenue can be generated at the early stages. Consider:

Fundraising Terms and Process

Build a Network First

Step 10: General Admin

Conclusions and Final Thoughts

You don’t need a 30-page business plan or a 50-person team to build something great in 2025. With AI-native tools and lean systems, a small team — or even a solo founder — can build, launch, and grow a serious company faster than ever before.

Focus on the signal you’re sending. Avoid noise and get back to building. Stay lean, iterate fast, and let customer feedback drive your momentum.
