How to build companies that change people’s lives
You’ve got the vision. You’re building something that matters. But how do you ensure that your product or service don’t just look good, but work to make the world a better place?
That’s what this section is all about: Designing for Impact. Not as a bolt-on or something you think about after launch, but as something that’s baked into the way you build.
This article covers three core practices:
Mapping a Theory of Change
Achieving Problem-Solution-Impact Fit
Embedding measurement into your product from the beginning
Let’s dive in.
1️. The theory of change for startups: a simple toolkit
A Theory of Change (ToC) is a tool that helps you clarify:
What change you’re trying to create
How you believe that change will happen
What you’ll need to do to make it real
It’s a map, not of your tech stack or user journey, but of your impact logic.
The building blocks
A simple Theory of Change includes:
Inputs – What you invest (time, money, expertise)
Activities – What your startup actually does (e.g. coaching sessions, product features)
Outputs – What is immediately produced (e.g. # of users trained, # of lessons completed)
Outcomes – The real-world effects (e.g. better literacy, improved job placement)
Impact – The long-term shift you’re aiming for (e.g. reduced unemployment, more equitable access to education)
Here’s a simplified example for a skills assessment startup:
Element | Example |
Input | Team + tech platform |
Activity | Deliver 20-minute skill assessments to jobseekers |
Output | 1,000 jobseekers complete assessments |
Outcome | 600 receive skill matches → 300 get interviews |
Impact | Shorter time-to-hire and better job fit at scale |
You can sketch this on a napkin. The point is to articulate your assumptions.
Once they're visible, you can test and refine them like any other startup hypothesis.
Tools to use:
Miro or Whimsical for visual mapping
Notion or Google Docs for a lightweight narrative version
Sticky notes on your office wall (…this still works)
Top tip 1: keep it lean
You don’t need a 30-page report. A 1-pager can go a long way, especially early-stage. What matters is clarity, not perfection.
Top tip 2: keep it research-based
Many companies create a theory of change that is essentially a logic model. For bonus points (i.e. ensuring improving accuracy and robustness), we suggest working (informally or formally) with researchers to form a more reliable logic model and theory of change. They can help verify your assumptions, ensure your hypothesis is grounded in sound, existing research and identify potential impact connections you may have missed (further highlighting possible areas of impact!). Check out this example of a research-based theory of change and judge for yourself: does your model look like this, with all the arrows?
2️. Problem-solution-impact fit
We all know about product-market fit, but in mission-driven startups, that’s not enough. You also need problem-solution-impact fit.
This means three things line up:
You deeply understand the problem
Your solution is meaningfully connected to solving it
Solving it produces measurable, desirable impact
Step 1: validate the problem
Too many startups jump to building without understanding the real-life constraints and root causes their users face.
You can’t design for impact if you haven’t asked:
“What’s blocking this person from succeeding right now?”
“Who benefits if this problem goes away - and who might resist the change?”
“Who is being left out when our solution is implemented?”
Great companies don’t just find problems. They find leverage points, the specific parts of a system where change is possible.
Step 2: map your solution to the outcome
Ask yourself:
“If someone uses this feature or service, what exactly is supposed to change in their life and how would we know if it did?”
If the connection isn’t clear or strong, that’s a red flag.
Step 3: test your impact hypotheses
Like any product hypothesis, your impact claims should be testable. There should be a clear, validated test for the hypothesis, one that can be implemented and tracked over time.For example:
“If students complete 5 micro-lessons per week, they’ll improve reading levels by 15%”
“If managers receive real-time coaching, team performance scores will rise within one quarter”
You can now build, test, and iterate on your impact, not just your interface.
3️. Embedding measurement into the product from day one
Too many startups treat measurement like a retroactive add-on:“We’ll worry about that after launch.” Or “We’ll look into impact after we have thousands of users”
But the smartest founders build their products so that evidence generation is a byproduct of use.
Not only does this help you learn faster, it also saves you from painful retrofitting later. Moreover, it protects you from a reputation damage: imagine you built a product that thousands use but researchers find has a negative impact on users!
Jenny Coogan, Brighteye mentor and co-founder at Newsela, commented:
"Absolutely. It's easy to fall into a trap of feature-creep where your product becomes so complex, it can be hard to isolate the data you need to measure impact. By understanding your impact measurement before you build, you'll think twice about any feature that might endanger your ability to track outcomes."
Step 1: decide what’s worth measuring
You don’t need to track everything. Focus on leading indicators of impact, early signals that someone is on the right track.
Begin with some outputs that you can easily measure. Examples:
Time to first job application submitted
% of learners who complete 3+ modules
Number of coaching sessions attended within 2 weeks
Pick 1-3 key metrics linked to your intended outcome. Make them visible to your team.
Step 2: build the impact indicators into your UX/LXD
Make it part of the flow, not a survey tacked on at the end. For example:
After completing a module, ask “How confident do you feel now compared to before?”
Prompt jobseekers to log outcomes directly (“Did you get an interview?”)
Use backend data to track time spent, actions taken, or follow-through
The goal is to make measurement frictionless, for you and your users.
Step 3: design with ethics and trust
If you're collecting impact data, you’re also collecting sensitive human data. Ethics is everything.
Be transparent with your users about what you're collecting and why
Allow opt-outs where reasonable and possibility to delete data when requested
Think hard about how the data could be misused, or misunderstood
Your impact story is only as strong as the integrity of your data.
Bringing it all together
Designing for impact isn’t a separate phase. It’s a way of thinking that informs:
How you define success
What you choose to build
How you measure and learn
When you map your theory of change, ensure problem-solution-impact fit, and embed lightweight measurement into your product, you’re doing more than chasing growth, you’re building something that works, matters, and lasts.
