The Ideal Partner Profile: Baker's Five Tests + Port's Red Velvet Rope
Not everyone who wants to join your certification program should be allowed to. David Baker's five analytical pre-tests and Michael Port's human-dimension scoring create a dual filter that protects your brand.
I once watched a founder accept a partner who checked every analytical box — strong niche, deep expertise, geographic reach, proven revenue. Six months later, that partner had alienated three other practitioners, publicly criticized the methodology on LinkedIn, and demanded custom modifications to the diagnostic tool that would have broken it for everyone else.
On paper, perfect. In practice, toxic.
The mistake wasn't in the analytical assessment. It was in ignoring the human dimension entirely. The founder had used David Baker's positioning criteria — market size, expertise depth, commercial viability — but had skipped the question that Michael Port insists comes first: will this person make the ecosystem better or worse?
You need both frameworks. Baker tells you whether a candidate can succeed. Port tells you whether they should be in your network. Running only one filter is like hiring someone based on their resume without an interview — or based on an interview without checking their qualifications.
After studying 1,340 expertise firms, Baker found one consistent trait among the successful ones: they were ruthlessly selective about who they associated with. Here's how to build that selectivity into a repeatable system.
Baker's Five Pre-Tests
The Analytical Filter for Market Viability
David Baker's positioning framework was designed to assess whether an expertise firm has the structural conditions for success. When applied to partner selection, these five tests reveal whether a candidate's practice can actually generate results using your methodology — not just whether they want to.
Test 1: Competitor Count (10-200). Ask the candidate to define their niche. Then count their competitors. Fewer than 10 competitors means the market is too small to sustain a practice — there simply aren't enough clients to go around. More than 200 means the candidate isn't specialized enough — they're competing with everyone, which means they're positioned for no one. The sweet spot is a niche with 10-200 competitors: large enough to be a real market, small enough that deep expertise creates genuine differentiation.
A candidate who says "I help businesses grow" has thousands of competitors. A candidate who says "I help mid-market healthcare organizations redesign their patient intake operations" might have 40. The second candidate can actually win.
Test 2: The "Drop and Give Me 20" Test. Put the candidate on the spot. Ask them to name 20 insights they've gained from working in their niche. Not general business wisdom — specific observations that could only come from repeated exposure to the same type of problem in the same type of organization.
A candidate with genuine pattern recognition can rattle off 20 insights without breaking a sweat: "Manufacturing companies with 50-200 employees always struggle with the handoff between engineering and production... The first sign of trouble is when the operations meeting gets cancelled three weeks in a row... Quality issues spike in Q1 because of seasonal hiring..."
A candidate who stalls at insight number 7 doesn't have the depth you need. Their expertise is theoretical. They've read about the niche. They haven't lived in it long enough to develop the pattern recognition that Baker calls the foundation of genuine expertise.
Test 3: Geographic Reach. Is the candidate's market geographically large enough to sustain a full practice? A specialist in restaurant consulting who only serves a single small city will run out of clients within a year. The same specialist serving a metro region of 5 million people has decades of runway.
Remote delivery has expanded geographic reach dramatically — but it hasn't eliminated the constraint entirely. Some engagements still require proximity. And even for remote-only practices, the candidate needs a market with enough density to generate consistent referrals and repeat business.
Test 4: Specialist Hiring. Could the candidate hire a specialist in their niche if they needed to? This is a proxy test for market maturity. If specialists exist in a niche, the niche is established — there's a recognized body of knowledge, a career path, and enough demand to support dedicated professionals. If no specialists exist, the niche may be too nascent or too niche-within-a-niche to support a partner practice.
Test 5: Purchasable Lists. Can the candidate buy a mailing list of prospects in their niche? This sounds crude, but it's one of Baker's most reliable indicators. If a list broker has a category for your niche, the market is defined — someone has already segmented and catalogued the buyers. If the list doesn't exist, the market may not be defined well enough for systematic business development.
Together, these five tests tell you whether a candidate's practice has the structural underpinning for commercial success. But they tell you nothing about whether the candidate will be a good partner.
Port's Red Velvet Rope Policy
The Human Filter for Ecosystem Fit
Michael Port created the Red Velvet Rope Policy to solve a problem that Baker's analytical framework can't touch: some people are analytically qualified and personally impossible. They have the right niche, the right expertise, the right market — and they drain the energy from every room they enter.
Port's framework scores candidates across five human dimensions. I've adapted them slightly for partner selection:
Energy. Does this person energize you or drain you? This sounds subjective, and it is — deliberately so. Your instinctive response to spending time with someone is a remarkably reliable predictor of how the broader community will respond. Partners who drain your energy will drain other partners' energy. That erosion is slow, invisible, and devastating.
Coachability. Will they follow the methodology, or will they insist on doing things their way from Day 1? Certified partners need to deliver your framework as designed — at least until they've earned the seniority to customize within guidelines. A candidate who pushes back on core methodology elements during the application process will push back ten times harder after certification.
Purpose Alignment. Do they believe in what you're building? Or are they just looking for a credential to add to their LinkedIn profile? Partners who are aligned with your mission stay through difficult periods — when clients are scarce, when the methodology evolves, when community demands increase. Partners who are credential-shopping leave the moment a shinier credential appears.
Entrepreneurial Drive. Will they actively sell and build their practice? Or will they complete certification and wait for clients to appear? Your ecosystem can't carry passive partners. Every certification slot represents an opportunity cost — the active, driven practitioner you could have accepted instead.
Vertical Depth. Do they have existing relationships in a specific market segment? A partner with 15 years of relationships in financial services will generate revenue faster than a partner who's "exploring" financial services. Existing relationships mean existing trust, existing referral sources, and an existing reputation that your certification amplifies rather than creates from scratch.
"Baker's tests tell you if the candidate can succeed. Port's rope tells you if they should be in your community. You need both answers to be yes."
Score each dimension on a 1-5 scale. Accept only candidates who hit 75% or higher on both frameworks — Baker's analytical tests and Port's human dimensions. That means a candidate needs a minimum of 15/25 on Port's criteria and must pass at least 4 of Baker's 5 tests. Anything less, and you're compromising.
Vertical vs. Horizontal Positioning
Why Your Founding Cohort Needs Both
Baker distinguishes between two positioning strategies that your partners will naturally gravitate toward:
Vertical positioning means industry-specific focus: "I help healthcare organizations," "I serve manufacturing companies," "I specialize in financial services." Baker's data shows that 85% of successful expertise firms position vertically. The advantages are clear — prospect discovery is easier (you know exactly which conferences to attend, which publications to read, which associations to join), and industry knowledge compounds with every engagement.
Horizontal positioning means discipline-specific focus across industries: "I help organizations with data governance," "I specialize in leadership development," "I focus on operational excellence." Horizontal positioning offers greater variety and economic resilience — if one industry hits a downturn, others remain strong.
Your founding cohort should include a deliberate mix of both. Here's why:
- Cross-referral power. A vertically positioned partner in healthcare and a horizontally positioned partner in operational excellence have complementary, non-competing practices. They can refer to each other without territorial anxiety. A cohort of 25 partners who all serve healthcare creates competition. A cohort with 5 healthcare verticals and 5 operational horizontals creates collaboration.
- Market intelligence. Vertical partners provide deep industry insight. Horizontal partners provide cross-industry pattern recognition. The combination produces richer benchmarking data and more nuanced methodology evolution than either could generate alone.
- Risk distribution. If your entire partner base is vertically positioned in one industry and that industry contracts, your ecosystem contracts with it. A mixed cohort distributes economic risk across multiple markets.
When evaluating candidates, map their positioning against your existing cohort. If you already have three partners in financial services, the fourth financial services applicant — even if analytically strong — may be less valuable than a weaker candidate in an unrepresented industry. Selection isn't just about individual quality. It's about portfolio composition.
The Partners You Say No To
How Rejection Defines Your Brand
Every founder building a partner network will face the same temptation: accept the marginal candidate because you "need the numbers." The cohort target is 25, you have 22 strong candidates and 3 maybes. The pressure to round up is enormous.
Don't.
Baker's research is unambiguous on this point. The firms that thrived over decades were consistently selective about their associations. Every time you accept a marginal candidate, you're making a statement to every partner who earned their place: "Your standards and theirs are the same." That's a statement your best partners will eventually resent — and act on by leaving.
Alex Moazed's path-dependency research in Modern Monopolies makes the stakes even higher. Early participants in a network set the quality standard permanently. If your founding cohort includes mediocre partners, the ecosystem's reputation carries that signal into every future cohort. It's far easier to start strict and relax later than to start loose and tighten.
There's also a counterintuitive demand effect. When you reject qualified candidates, word gets around. "They turned down 100 applicants to accept 22" is a more powerful positioning statement than any marketing copy you could write. The rejected candidates don't disappear — they become the first applicants for Cohort 2, carrying a level of urgency and preparation that first-time applicants rarely match.
Launch with 22 excellent partners instead of 25 adequate ones. The three empty seats aren't a weakness. They're proof that your standards mean something.
The dual filter — Baker's analytical pre-tests and Port's Red Velvet Rope — isn't bureaucracy. It's brand protection. Every partner you accept represents your methodology in the market. Every partner you reject protects the partners who made the cut. Build the filter before you need it, apply it without exception, and trust that the right candidates will clear both bars.
