Founders should look for two broad situations:
Unmet need
→ the customer has an important need with no adequate solution
Underserved need
→ solutions exist, but they do not serve the customer well enough
The opportunity is not simply:
“There is no competitor.”
It is:
“Customers still have an important problem despite the options available.”
1. What Is an Unmet Need?
An unmet need exists when customers want an outcome but do not have a satisfactory way to achieve it.
They may currently:
do nothing,
tolerate the problem,
perform the work manually,
create their own workaround,
depend on people or processes that were not designed for the task.
Imagine a small business that needs a particular workflow automated.
If no practical solution exists, employees may handle it through:
email
→ spreadsheets
→ phone calls
→ manual checking
The need exists even though no dedicated product exists.
2. What Is an Underserved Need?
An underserved need is different.
Solutions already exist.
But customers may find them:
too expensive,
too complex,
too slow,
unreliable,
difficult to use,
difficult to integrate,
designed for larger organizations,
missing important features,
poorly suited to their workflow.
This means:
Existing solution ≠ problem fully solved
Competition does not automatically eliminate opportunity.
Sometimes competitors reveal that customers already care enough to spend money.
The founder's job is to understand:
“What remains unsolved?”
3. Unmet vs Underserved
Consider a simplified example.
Unmet
A customer says:
“There is no practical tool for this, so we do it manually.”
Underserved
A customer says:
“We already use software, but it is too complicated for our team.”
Both can create opportunity.
But they require different strategies.
For an unmet need, you may need to prove:
customers want a new category of solution.
For an underserved need, you may need to prove:
customers will switch from an existing alternative.
4. Look Beyond the Product Category
Customers rarely wake up thinking:
“I need a new SaaS product.”
They want an outcome.
For example:
A restaurant manager may want:
accurate inventory
rather than
inventory software
A salesperson may want:
qualified customer conversations
rather than
another CRM feature
A small manufacturer may want:
less equipment downtime
rather than
a maintenance dashboard
Focus on the desired outcome.
Then study how customers currently try to achieve it.
5. Workarounds Reveal Unmet Needs
Look closely when customers build their own solutions.
Examples include:
spreadsheets,
paper records,
messaging groups,
templates,
manual reminders,
multiple tools connected awkwardly,
custom scripts,
extra employees performing repetitive work.
These are important signals because customers are effectively saying:
“No existing option solves this well enough, so we created something ourselves.”
The workaround itself is not proof that a startup should exist.
But it is strong evidence worth investigating.
6. Complaints Reveal Underserved Needs
When customers already use a product, ask:
“What do you dislike about the current solution?”
Possible answers:
difficult onboarding,
excessive features,
missing capabilities,
high price,
slow support,
poor reliability,
bad integrations,
rigid workflow.
But do not stop at complaints.
Ask:
“What do you do because the existing solution fails here?”
That behaviour reveals whether the dissatisfaction actually matters.
7. Look for Customer Segments Others Ignore
Sometimes the problem is solved well for one segment but poorly for another.
Imagine software designed primarily for large enterprises.
It may require:
long implementation,
specialist administrators,
expensive contracts,
complex configuration.
Large organizations may accept that.
Smaller companies may not.
The underlying need may already be solved in the market, but not for this customer segment.
Potential underserved segments can differ by:
company size,
industry,
geography,
workflow,
technical capability,
budget,
regulation,
purchasing behaviour.
The opportunity can come from serving the neglected segment better.
8. Look for Over-Served Customers Too
Customers can also be underserved because the solution gives them too much complexity.
Suppose a customer only needs:
three important features,
quick setup,
simple pricing.
Existing products may offer:
dozens of modules,
complex configuration,
enterprise workflows,
long training.
More features do not always create more value.
Sometimes the opportunity is:
simpler
rather than
more powerful
9. Follow Repeated Customer Friction
A useful discovery sequence is:
Need
→ Current alternative
→ Friction
→ Consequence
→ Workaround
→ Opportunity
For example:
Need
A team needs to coordinate recurring approvals.
Current alternative
Email.
Friction
Requests become difficult to track.
Consequence
Approvals are delayed.
Workaround
Employees manually maintain spreadsheets and reminders.
Opportunity
A simpler coordination process may deserve testing.
Notice that the opportunity comes from understanding the entire workflow—not merely noticing that email exists.
10. Ask Why Customers Have Not Switched Already
If customers dislike existing solutions, an important question is:
“Why are they still using them?”
Possible reasons:
switching cost,
familiarity,
contract lock-in,
data migration,
integration difficulty,
lack of alternatives,
perceived risk,
employee training.
This matters because dissatisfaction alone does not guarantee switching.
A new solution must usually be sufficiently better to overcome the cost of change.
11. Search for Non-Consumption
Sometimes the most interesting customers are not using any product.
This may happen because existing solutions are:
unaffordable,
inaccessible,
too difficult,
inappropriate for their workflow.
Instead of asking only:
“Which competitor are customers using?”
also ask:
“Who wants the outcome but currently uses nothing?”
Non-consumption can reveal unmet demand—but it can also mean the need is not important enough.
That requires validation.
12. A Practical Discovery Example
Imagine freelancers need help managing late client payments.
Existing tools may already create invoices.
But customer interviews reveal:
invoice creation is easy,
payment follow-up is manual,
reminders are inconsistent,
freelancers repeatedly check bank accounts and send messages.
The opportunity is not necessarily:
“Build another invoicing app.”
The deeper underserved need may be:
“Help freelancers manage payment follow-up.”
This is why founders should study the gap between the desired outcome and current reality.
13. Warning Signs
Be cautious when:
Customers complain but never act
The dissatisfaction may be mild.
Alternatives are already considered good enough
Switching motivation may be weak.
The underserved segment is extremely small
The problem may be real but commercially limited.
Customers cannot explain the consequence
The friction may not matter enough.
Your proposed improvement is tiny
A slightly better solution may not overcome switching costs.
14. A Founder Opportunity Map
For each customer need, ask:
Desired outcome
What does the customer actually want to achieve?
Current alternative
How do they accomplish it today?
Gap
What does the current approach fail to deliver?
Consequence
Why does that failure matter?
Workaround
What does the customer do to compensate?
Satisfaction
Are customers happy with the existing option?
Switching barrier
What prevents them from changing?
Evidence
Are customers spending time, money, or effort because of the gap?
This reveals whether the market contains a meaningful opening.
15. Founder Decision
When you see a possible unmet or underserved need, ask:
What outcome does the customer want?
How do they achieve it today?
What is still missing?
Who feels that gap most strongly?
What does the gap cost them?
What workaround have they created?
Why haven't existing solutions solved it?
What would make customers change?
Then test the answers with real behaviour.
16. The Opportunity Signal
An interesting pattern is:
Important desired outcome
+
weak current solution
+
visible customer friction
+
existing workaround
+
willingness to change
That combination can indicate an unmet or underserved need worth validating.
It still does not prove your solution will succeed.
It tells you there may be a meaningful gap in the market experience.
17. Remember This
Do not ask only:
“Does a solution already exist?”
Ask:
“Does the customer feel adequately served?”
A market with competitors can still contain large gaps.
And a market with no competitors does not automatically contain demand.
The core principle is:
Startup opportunities often exist in the gap between what customers need and what current alternatives actually deliver.
Find the gap.
Then determine whether customers care enough to cross it.
