#HealthForAll means health for all. Not for some. Not for most.
That is @WHO's mission. It is also part of Madiba's enduring legacy: that human rights, including the right to health, belong to everyone, regardless of income.
On #MandelaDay , I call on world leaders to turn that promise into reality: health for all.
As a founder, If you’re raising venture capital, sitting in board meetings, or speaking with institutional investors, there are about 30-40 business terms you should know cold. I have been doing this for more than 10years so these are the ones that matter.
⸻
1. WACC — Weighted Average Cost of Capital
This is one of the most important concepts in corporate finance.
Meaning
The average cost of every dollar the company uses to finance itself.
Money isn’t free.
A company can obtain money from:
Equity (selling shares)
Debt (bank loans, bonds)
Each has a cost.
WACC combines both.
Example:
You need ₦100 million.
You raise
₦60m from investors
₦40m from the bank
Investor expects 20% return.
Bank charges 10% interest.
Your WACC is
(60% × 20%) + (40% × 10%)
= 12% + 4%
= 16%
Meaning:
Every project you invest in should ideally earn more than 16%.
If not, you’re destroying value.
⸻
Why VCs care
Suppose you tell a VC
“Our expansion will generate 8% yearly.”
If your WACC is 16%
The VC thinks
“Why are you investing in something earning less than your cost of capital?”
Bad management.
⸻
2. CAC — Customer Acquisition Cost
One of the first numbers investors ask.
Formula
CAC = Marketing Spend ÷ Customers Acquired
Example
You spend
₦5 million on ads
Acquire
500 customers
CAC
= ₦10,000
Meaning
It costs you ₦10k to get one customer.
⸻
3. LTV — Lifetime Value
How much one customer generates before leaving.
Example
Customer pays
₦10,000/month
Average customer stays
36 months
Revenue
= ₦360,000
Gross margin
70%
LTV
≈ ₦252,000
⸻
Investors love
LTV : CAC
If
LTV = ₦250k
CAC = ₦10k
Ratio
25:1
Fantastic.
Generally:
Below 1:1 → Losing money
Around 3:1 → Healthy
5:1+ → Excellent (assuming the numbers are sustainable)
⸻
4. Burn Rate
How fast you’re spending money.
Example
Cash in bank
₦120m
Monthly expenses
₦10m
Burn rate
₦10m/month
⸻
5. Runway
How long before you run out of cash.
Cash
₦120m
Burn
₦10m/month
Runway
12 months
VCs almost always ask
“How much runway do you have?”
⸻
6. EBITDA
Earnings Before Interest, Taxes, Depreciation and Amortisation
Measures operating profitability before financing and certain accounting charges.
Think of it as
“How much does the business generate from operations?”
Very common in acquisitions.
⸻
7. ARR
Annual Recurring Revenue.
Critical for SaaS.
Monthly subscriptions
₦2m
ARR
₦24m
Investors love growing ARR.
⸻
8. MRR
Monthly Recurring Revenue.
If subscriptions
₦500k
Next month
₦700k
MRR increased.
⸻
9. Gross Margin
How much remains after direct costs.
Example
Revenue
₦100m
Cost to deliver
₦30m
Gross margin
70%
High gross margins usually make companies more scalable.
⸻
10. EBITDA Margin
EBITDA ÷ Revenue
Shows operational efficiency.
⸻
11. ROI
Return on Investment.
Simple.
Invest
₦1m
Earn
₦1.5m
ROI
50%
⸻
12. IRR
Internal Rate of Return.
Measures the annualised return of an investment over time.
Private equity firms use this constantly.
Higher IRR = better investment.
⸻
13. NPV
Net Present Value.
Money today is worth more than money tomorrow.
NPV discounts future cash flows to today’s value.
Positive NPV
Good investment.
Negative
Reject.
⸻
14. Cap Table
Capitalisation Table.
Shows
Founders
Investors
Employee stock options
Ownership percentages
Every startup should have one.
⸻
15. Dilution
Every fundraising round usually reduces existing shareholders’ percentage ownership.
Example
You own
100%
Raise investment
Now own
80%
You’ve been diluted.
⸻
16. Valuation
What the company is worth.
Pre-money
Value before investment.
Post-money
Value after investment.
Example
Company worth
₦900m
Investor puts
₦100m
Post-money valuation
₦1 billion
Investor owns
10%
⸻
17. TAM
Total Addressable Market.
Entire possible market.
Example
Nigeria spends
₦5 trillion yearly on facilities management.
TAM
₦5 trillion.
⸻

Earlier today, our Aguata champions were engaged in an immersion session, introducing them to the limitless world of possibilities through technology, and how they can become global citizens even from their rural schools in Aguata LGA.
At the 2026 Pan-African Innovation Boot Camp holding in the prestigious Ntare Louiselund International School, Kigali, our champions are sharing learning rooms with students from different countries, and as such, widening their world views.
They are no longer just finalists of our 2026 Aguata Best Student Challenge. Our focus is for them to see beyond Aguata local government area of Anambra State, Nigeria.
A step at a time, we will transform as many of our young people as possible.
Impossibility is Nothing.
Currently in New York with one of our kids @chessinslums as he begins his sojourn towards earning the US National Master title under the supervision of Grandmaster Alex Lenderman.
We are all rooting for you Jamiu🇳🇬❤️. Give them hell!
When Alex was fighting for victims that suffered in the hands of JAMB he didn’t ask of tribe before he fought
When he ensured Nigeria get a spot at the STEM Olympiad he did it for Nigeria
Stop tribalism
I apologise, we had to block Nigerian residents from the faucet because most of them were withdrawing the $5 that was meant to be for testing the product.
A Nigerian student did what no one had done in 99 years.
Stella Chinelo Emelife 🇳🇬 graduated as the Best MSc Chemistry student at the University of Mysore, India 🇮🇳, winning 20 Gold Medals, 5 cash prizes, and a university scholarship.
Congratulations!
Thank you for giving these children a chance to shine their lights on a global stage.
Posterity will forever be kind to you. This is Day1
So if Alex Onyia didn’t decide to take these kids to Rome, you mean the world would not have seen us win gold?
Some other country would have won and we would have thought they were the brightest on earth?
Bad Governance is hiding the greatness of Nigerians.
I’ve said on previous tweets that Nigerians are the brightest and smartness people on earth. No enabling environment to showcase that brilliance.
Nigeria is the Champion of the world. The Nigerian flag was flown in Rome, Italy.
The three wise men of the East have done it, they made our country Nigeria proud.
Nigeria has won FOUR Gold medals at the International STEM Olympiad in Rome, Italy.
Chimdiebube Onwubiko won Gold in Grade 9.
Don Anele Munachimso won 2 Gold medals, including a Gold medal in Science (Grade 11). He is the best in world science. He is the best in IGCSE Chemistry category in Nigeria as well.
Onyedikachi Egejurum won a Gold medal in Mathematics in the World Primary Category.
Egejurum Onyedikachi is now the best in the world in the Mathematics Primary Category.
This is a perfect triumvirate. THEY DID IT! Congratulations to the Geniuses. Alex Onyia is making education the topic of discussion in Nigeria once again. He has declared a State of Emergency in Education in his own personal capacity. He is making classroom teachers & Nigeria proud. He deserves a national honors.
If Alex did not take the kids to Rome, another country would have won the Gold medals. We must end bad governance in Nigeria. THE BEST OF US MUST LEAD THE REST OF US! 🥇🥇🥇

In Ghana, any child who qualifies to represent the country in the International Maths Olympiad gets an automatic scholarship to MIT.
Interestingly, the head of their local Olympiad unit is a Nigerian. He left Nigeria the moment the Nigerian government stopped sponsoring our students for the program.
MIT students regularly travel to Ghana to prepare their students for the Olympiad.
It is also a huge talent pipeline for a company called Jane Street. They are the major sponsor for Ghana Maths Olympiad. Their starting salary is between $300k - $600k annually.
My mum owns a primary and secondary school somewhere in Akeja, Ogun Sate. There is this man, Papilo, a supplier who handles FMCG products in that area. He comes Tuesdays, Thursdays, and Fridays. Sundays are for my mum and other school owners stocking up for students during break.
He is not the only one. They are everywhere like that.
One thing I know is that most of these sellers don’t pay him immediately, They pay on the next supply day or after a week. Sometimes it stretches to 3 supplies before payment clears.
I've watched him argue back and forth with customers who say no money yet. He still gives them all or little. I've seen this for over 15 years growing up. This is the practice across every informal market in Nigeria. This is Africa’s informal supply chain.
Papilo knows all his customers. He knows their children’s names. He argues, negotiates, and finds a middle ground. No App or AI can replicate this.
Papilo now runs plenty of small kekes distributed all over Akeja and beyond.
In African businesses, relationships aren’t just nice-to-haves. They are part of the infrastructure. And this is where the majority of our builders get it wrong.
A techie once went to get bread at a store and stumbles on a sole distributor supplying them wines. He thinks “so this is how these get their stocks” he goes home to google the numbers and sees millions of retailers, no central database, orders on phone call, cash payments, manual records. He sees the classic Manufacturer → Distributor → Wholesaler → Retailer chain and he goes “yes! This is a gap. This is untapped. I can build this on an app”.
Actually, he is right. But here is what he missed;
The supplier extends credit
The wholesaler knows who always pays at each time.
The sales rep knows whose child just got admitted into university.
The delivery driver knows which shop opens late or earlier
None of this can fit in an app database because they are the everyday circumstantial reality of Nigerian business owners. Your app can’t document this.
A retailer doesn’t always buy from who is cheaper. She buys from who’s delivered consistently for years. The one who lets her pay next week. The one who picks up the phone immediately there is a problem.
See your app can calculate credit just fine. But the distributor knows Mama Olomi missed payment because her shop flooded last week. That context is the business in this part of the world.
You will think funding fixes this but marketForce had $42M and still died. Sendy had $27M, Medsaf had $7M.
Your investors will push you to the usual playbook; free delivery, discounts, cashback, promotions, etc and growth will look incredible at first but the moment the subsidies disappear, you will start to compete with relationships using economics alone.
Then you’d realize your capital didn't buy survival, it brought speed to a broken model. Somebody say Reality!
Now let’s look at the ones who didn’t die. They simply mutated.
Sabi moved into traceability/export infra. OmniRetail leaned into embedded finance.
Sendy’s co-founder built TABB on trade credit data.
Rather than say we’re replacing distributors, they became the operating system behind the distributors helping them;
📍 Manage inventory
📍 Collect payment
📍 Access financing
📍 Discover retailers
📍 Forecast demand
📍 Coordinate logistics
This is the lesson for anyone building in African informal market.
Don’t ask How do i remove the middleman
Ask, what valuable job is the middleman doing that technology can make easier?
Don’t compete with the market woman, equip her. Build the layer she can’t build herself (credit history, verified supply chains, payment infrastructure, etc).
This is because Africa’s distribution problem was never about apps vs humans. It’s about who controls the trust layer. Build that, not the marketplace.

I just got information that Nigeria has the opportunity to appeal its position at the International Maths Olympiad. This year’s final will be held in Shanghai, China, from July 10th to 21st.
If they succeed, they can participate again starting in 2027. They must commit to funding their students for at least the next 5 years.
The last time Nigeria participated was in 2019. This is the most prestigious academic competition in the world, and we have denied our children this privilege for so many years.
The Ministry of Education, through the National Mathematical Centre, should do the needful now.
One decision can change the entire course of your life.
If you’re a Nigerian student and you’ve been thinking about applying for the @OPay_NG National Innovation Challenge 2026, this is your sign to stop waiting and take that final leap of faith.
I made this video to show you how to complete your application in just a few minutes. From using Gemini to generate ideas to the final submission.
In partnership with Google and 3MTT, OPay is giving Nigerian students a chance to learn, innovate, compete, and win.
Your idea doesn’t have to be perfect, it just needs to solve an important problem.
Applications are still open till July 3rd.
All the best.
The full names of the 46 kidnapped Oyo children. They are still in terrorist captivity as I type this tweet.
Pls share this post everywhere
Let their names be known worldwide.
Kindly lend your voice I beg you.
On today’s children’s day,
If this is all you do, you’ve done a lot.
