The Sweet Spot Formula is a four-quadrant filter for choosing a business idea. Quadrant one is your 10% Edge — results you've already achieved that put you just ahead of those you'd serve. Quadrant two is who you serve and the specific challenge or desire you solve for them. Quadrant three is profit potential, validated by whether people already spend money in that space. Quadrant four asks whether the topic lights you up enough to live and breathe it. When all four align, you have a viable starting idea.
Origin
Porterfield developed the formula after her own first business — one-on-one social media services she grew to hate — taught her that a good idea has to sit at the overlap of skill, market, and enjoyment, not just one of them.
Core principles
- 01You already have something teachable — you don't need more certification or time.
- 02A market with existing products is a validator, not a threat.
- 03The idea only needs to light you up enough to talk about it constantly, not be your life's passion.
- 04Your first idea is a starting point, not your end-all-be-all.
How to run it
- 1
Map your 10% Edge
Inventory every result you've produced for yourself, clients, or even family and friends, professionally and personally. You only need to be 10% ahead of the people you'll serve.
Pro tip You likely already qualify — most people have several areas where they excel.
Watch out Don't wait to be the expert of all experts; that belief keeps you stuck.
- 2
Choose who you serve
Identify the audience whose challenge, pain point, or desire you can solve with your edge, and get clear on exactly what they need.
Pro tip Align this directly with your edge — the two quadrants must connect.
- 3
Validate profit potential
Ask whether there are books, podcasts, courses, coaches, or consultants already earning in this space. If people spend money there, that's your first validator.
Pro tip Existing competitors are a green light — 'ding ding ding' — not a reason to quit.
Watch out Creating a product for a problem nobody has is the most common failure.
- 4
Confirm it lights you up
Check that you enjoy the topic enough to eat, breathe, and sleep it, since you'll be teaching or doing it constantly.
Pro tip It doesn't have to be your grand life passion — sustained enjoyment is enough.
In the wild
Porterfield walks through a hypothetical nutritionist who wants to do virtual meal planning: their edge is nutrition training, their audience is people who want meal prep done for them, and validation comes from checking whether books, courses, and coaches already sell in that niche.
→ Existing products in the space confirm demand and become the validator that the idea can make money.
Common mistakes
Treating existing competition as a stop sign
Beginners often abandon an idea because courses already exist on the topic. In reality, a crowded market proves people spend money there — the goal is to prove demand, not to be first.
Demanding it be your life's passion
People wait for a single grand passion. The formula only requires that the topic energizes you enough to talk about and teach repeatedly.
Is it for you?
Best for
Corporate professionals or side-hustlers choosing a first course, coaching, or service offer.
Not ideal for
Founders chasing a novel, category-defining product where no comparable market exists yet.
