Building in Public: A Guide for African Founders

Building in public means sharing your progress, numbers and lessons openly while you build, usually in a short weekly post on LinkedIn or X. For African founders it makes you easier to find for hires, customers and investors who would never otherwise hear of you. Share progress and lessons, and keep customer data, unsigned deals and core technical secrets private.

I co-founded Hackhouse, a builders' hub in Nairobi. Many of us were raised to keep work private until it is finished, and that instinct has its place. This guide covers what building in public is, why it helps founders here, what to share and what to hold back, and how to start. I checked every sourced fact on 5 November 2026.

What does building in public mean?

Building in public is the habit of showing your work while you are still doing it. That includes:

• What you shipped this week.
• A number that went up, and one that went down.
• Why a customer left, without naming them.
• A pricing test that did not work.
• The role you are hiring for.
• A decision you are stuck on, with a request for advice.

The point is a steady record over time. A single post proves little, while a year of weekly posts shows how you think, how fast you move and whether you keep your word.

Why should African founders build in public?

The people who could help a young African company often cannot see it: an engineer in another city, an angel in the diaspora, a corporate buyer, a journalist. Posting progress makes you findable.

Capital is also concentrated. Partech counted 462 equity deals across Africa in 2025, worth US$2.4 billion, and Kenya led the continent in total capital raised with US$1.04 billion (Partech). With so few deals spread across so many startups, a public record of steady traction gives an investor something to check before the first meeting.

What does building in public do for a startup?

• It helps you hire. A weekly post about what you shipped tells candidates what working with you is like.
• It helps you sell. Each update reaches customers who are not ready to buy yet, so they know your name when they are.
• It helps you raise. Investors can see a line of progress over months, which is easier to trust than a deck that appears from nowhere.
• It keeps you accountable. When you say in public that something ships on Friday, you have a strong reason to ship it on Friday.

What should I share, and what should I keep private?

A useful rule: share the progress and the lessons, and keep the recipe.

Share:

• Features shipped and what you learned from them.
• Rounded or relative numbers, such as growth rates, if exact revenue feels too exposed.
• Mistakes and what you changed.
• The problem you are working on and why it matters.

Keep private:

• Customer names, screenshots, phone numbers or photos, unless the customer has agreed in writing.
• Unsigned deals and partnerships.
• Technical secrets that took you years to work out.
• Anything your investors or partners have asked you to keep confidential.

Kenyan law backs up the first point. Section 37 of the Data Protection Act 2019 bars commercial use of personal data without the data subject's express consent, unless another written law allows it (CIPIT, Strathmore University). In a January 2025 decision, the Office of the Data Protection Commissioner said employers must get explicit consent before using an employee's image for commercial purposes, and that the burden of proving consent sits with the employer (EY). Ask your team and customers before they appear in a post.

Will someone steal my idea if I share it?

It can happen, and the risk is worth weighing honestly. Your execution, your team, your relationships, your speed and how well you understand your customer are hard to copy from a post. The precise technical method, the data only you hold and the partnership still under negotiation are easier to copy, so keep those back. In my view, for most early founders, staying unknown carries more risk than being copied.

Should I share failures in public?

Sharing only wins starts to read like advertising. Sharing what went wrong, with care for the people involved, earns more trust and helps the founders who come after you.

When the Nigerian open banking company Okra closed, co-founder Fara Ashiru confirmed it in a statement to the media: "The company made the decision to wind down operations in May. It was an incredible journey; we built impactful technology, worked with some of the biggest brands across the continent, and helped pioneer open banking in Africa" (Nairametrics). A clear public statement lets customers, staff and the wider ecosystem understand what happened. A full account of the lessons, when the founder is ready, teaches even more.

How do I start building in public?

1. Pick one channel where your people already gather. For many founders that is LinkedIn or X; for some it is a WhatsApp or Telegram community.
2. Commit to one post a week for twelve weeks before you judge it.
3. Use a simple shape: what I shipped, one number, one lesson, one thing I am stuck on.
4. Reply to every comment in the first hour or two after you post.
5. Keep a private list of things you will never share, and check each post against it.

The early posts may get little response. They still build the archive that the right person will read when they find you. Our guides to building a personal brand as a founder and giving a great Demo Day presentation go further.

To see founders share their progress in person, come to the Hackhouse Cohort 4 Demo Day on Tuesday 17 November 2026 at 5pm; details are on our events page. Our communities are a good place to post your first weekly update and get feedback.

Frequently asked questions

What is building in public?

It is the practice of sharing your startup's progress, numbers, decisions and lessons openly as you go, usually in regular social media posts.

Is building in public a good idea for African startups?

For most early founders, yes. It makes you visible to hires, customers and investors. Keep private anything that would harm customers or give away a core advantage.

Should I share my revenue publicly?

Only if you are comfortable with competitors seeing it. Growth rates, customer counts or rounded figures show progress without exposing exact revenue.

Can I post photos of my customers or team?

Get their consent first. Kenyan data protection law requires express consent for commercial use of personal data, and the ODPC has applied this to images used in marketing.
