What Angel Investors Look for in Founding Teams

Brian Nichols is the co-founder of Angel Squad, an angel investing community where aspiring and active angels learn from Hustle Fund’s approach, review curated deal flow, and connect with peers.

A convincing team slide can hide an unanswered question about who will build the product, win customers, or handle a hard decision. When you’re considering an early-stage investment, you need evidence of how the founders work. These five signals help you connect a team’s strengths and gaps to the company it’s trying to build.

Start with the investment case

Angel investors look for a team that can execute, a real customer problem, a market with room to grow, and evidence that the proposed business can work. They also consider how the company will use the investment, the deal’s terms, and a plausible way for investors to eventually receive proceeds. Individual angels weigh these differently.

The British Business Bank’s angel investment checklist covers team, product, market, business model, revenue, growth plans, and investor expectations. A strong team is one part of the investment case.

At pre-seed, there may be little operating history. The team’s knowledge, work, and decisions give you evidence while the business is still taking shape.

In a founding-team experiment published in the Journal of Finance, Shai Bernstein, Arthur Korteweg, and Kevin Laws randomized the information investors received about startups on AngelList. The average investor responded strongly to founding-team information. The result concerns early investor interest; it doesn’t establish a universal formula for successful investments.

Our practical starting point is the next milestone. Name the business outcome the founders intend to reach with this round, then ask whether their capabilities and operating choices support it. A team aiming to deliver its first paid pilot needs different evidence from one preparing to hire managers and expand an established sales process.

Five signals to look for in a founding team

The useful signals are founder-market fit, execution and learning, capability coverage, working relationships, and a credible commitment plan. Each needs a concrete example. Descriptions such as “experienced,” “passionate,” and “complementary” leave too much unanswered.

1. Relevant insight into the customer’s problem

Founder-market fit means the founders have knowledge, access, or skills that help them solve this particular problem. Their background matters when it creates an advantage in the work ahead.

For a startup serving property managers, a founder who has managed buildings may understand why maintenance requests get lost, who approves software spending, and what makes a new tool hard to adopt. Those details can improve product decisions and early sales. Ten years in real estate, without a connection to the buyer or workflow, tells you less.

Ask questions that connect experience to decisions:

• Customer insight: What did the founders learn that changed their view of the problem?
• Access: How did they reach their first potential customers, and can they reach more?
• Specific advantage: What can they build, understand, or distribute that another capable team would struggle to reproduce?

Relevant insight can also come from outside the industry. A founder might have lived with the problem personally or developed a detailed understanding through customer conversations and hands-on work. Our perspective on early-stage team evaluation leaves room for those founders.

Treat a school or employer as a starting point for a conversation about the work someone did. In deep tech, specialized training and related technical projects may be direct evidence that a founder can build the product.

For a sales tool, the same credential may tell you little about understanding sales teams. The connection to the company determines its value.

2. Execution that produces learning

Our co-founder and general partner Eric Bahn defines hustle as “great execution meets high velocity.” That gives you two things to examine together: what the founders accomplish and how quickly they turn results into better decisions.

Shipping ten features says little if customers use none of them. A smaller change that improves a customer’s workflow, followed by a clear explanation of what the team learned, gives you more useful evidence.

Ask the founders to walk through a recent sequence:

1. What did they believe would happen?
2. What did they build or do?
3. What happened with customers?
4. What did they change afterward?

Consider a hypothetical startup whose founders initially believe buyers want a detailed analytics dashboard. Pilot customers keep asking for a reliable weekly export instead.

The team narrows the product, ships the export, and watches whether customers keep using it. You can assess how the founders handled evidence that contradicted their original plan.

Receptiveness to feedback includes judgment. A founder can take advice seriously and reject it for a clear reason. Agreement with everything an investor says is weak evidence of learning.

Match your expectations to the stage and business. A pre-seed team may have customer notes, a prototype, and a record of product decisions. A seed-stage team with customers should have more evidence of repeatable delivery.

Hardware and scientific development also have different timelines from a small software release. Evaluate progress against the actual constraint.

3. Capabilities that cover the next milestone

Complementary skills matter when they cover work the company needs. There’s no required arrangement of one technical founder, one business founder, and one operations founder.

Three engineers could be a sensible founding team for a difficult infrastructure product. They still need a credible way to reach buyers and support customers.

Two commercially experienced founders could be well suited to a service-led business. If their plan depends on original software, someone needs the ability and responsibility to build it.

Map the milestone to a small set of outcomes, then identify an owner and evidence for each:

• Product delivery: Who owns the usable product, and what have they already delivered?
• Customers: Who owns reaching, selling to, and serving the initial buyers?
• Operations: Who owns the budget, priorities, and coordination needed to deliver?
• Critical specialist work: Does this company need capabilities such as manufacturing, scientific development, or regulatory expertise at this stage?

One founder can own several outcomes. A solo founder can be a credible investment when the responsibilities, limits, and support plan are clear. Adding a co-founder introduces another relationship and another set of decisions; founder count alone doesn’t answer whether the work is covered.

Distinguish the people doing the work from those lending their names. An advisor who spends an hour each month on introductions has a different role from an employee responsible for customer onboarding.

A contractor’s contribution has a scope and a duration. Those arrangements can help, but they need to match the dependency.

An open role deserves attention when it threatens the milestone. Ask who covers it now, what the hire must accomplish, and when the company needs that person. A hiring plan is more credible when it includes a defined role, an available budget, and specific recruiting progress.

4. A working relationship that can handle disagreement

Longstanding friendship and previous collaboration are useful context. The evidence you need is how the founders make decisions and share responsibility today.

Our co-founder and general partner Elizabeth Yin wrote in Democratizing Knowledge, our 2021 collection of her posts, “A top reason I've seen for companies failing is co-founder drama.”

Ask for a recent disagreement about something consequential, such as product scope, spending, or hiring. Find out what each person wanted, how the decision was made, and what happened afterward. A team can disagree productively while remaining clear about who owns the final decision.

Pay attention to concrete behavior:

• Decision ownership: The founders can explain who decides within each area and how they resolve a deadlock.
• Shared priorities: They describe the same near-term goal, even when they have different views about the route.
• Accountability: They can describe a missed commitment without pushing all responsibility onto someone else.
• Useful disagreement: Each person can contribute, challenge an assumption, and explain the other founder’s reasoning fairly.

Treat differences in answers as prompts for clarification. One founder may be talking about this quarter while another describes the long-term plan. Contradictions about who runs the company or what the round will fund are more consequential than differences in wording.

5. Commitment and hiring plans that fit the work

Commitment shows up in operating choices. Ask what time each founder has available, what competing responsibilities remain, and how the proposed funding changes those constraints.

A founder’s current job, caregiving responsibilities, or research position needs context. The investment question is whether the team can reach its milestone with the capacity it has, and whether a necessary transition is specific and workable.

A hypothetical founder who plans to leave a job after the round closes should be able to explain the transition date, the work already completed, and who handles customer needs in the meantime. A plan that depends on an unnamed person eventually becoming available leaves a dependency unresolved.

Recruiting evidence also needs context. Someone who has accepted an offer provides different evidence from someone who had an introductory conversation.

Ask why a candidate wants to join and what the company can offer. Don’t assume a famous advisor proves the team can recruit the employee it needs.

Tie hiring to a bottleneck. If the founders can build and sell but customer setup consumes most of their week, an implementation hire may advance the next milestone more than another generalist. The hiring order should have a business reason.

Turn the team slide into a milestone map

A team slide is a compressed set of claims. You can organize those claims as a milestone, the people responsible for it, and the work that supports confidence in them. Keep a separate place for gaps, so a polished biography doesn’t obscure an uncovered responsibility.

Consider a hypothetical property-management software company raising to deliver three paid pilots. Its founders include a former property manager and an engineer who built workflow software. Those biographies sound relevant. The milestone map makes the case more specific:

• Deliver the pilot product: The engineer owns it and has already built a working prototype around a maintenance-request workflow.
• Secure and support customers: The former property manager owns it, has identified the purchasing decision-maker, and has ongoing conversations with potential pilot customers.
• Keep setup manageable: Neither founder has solved onboarding at scale. They plan to handle the first pilots themselves, record the work required, and hire against that workload once they understand it.

Now change one fact. The engineer is an advisor with limited availability, while an unnamed contractor is expected to build the product after funding.

The customer insight is unchanged, but your view of delivery risk should change. The same team-slide layout can contain very different investment evidence.

Keep the strength of each observation clear. A prototype demonstrates something has been built. A customer conversation demonstrates access and learning.

A paid pilot adds evidence of willingness to pay. None establishes everything about the company.

Separate an ordinary gap from a reason to pass

Early teams have gaps. The useful distinction is whether a gap is understood and manageable within the investment plan.

Limited sales experience can be manageable when a founder is already reaching customers, learning from objections, and taking responsibility for sales. It’s more concerning when everyone assumes that hiring a salesperson will solve an undefined customer problem.

Similarly, recent co-founders have less working history. That warrants more attention to their actual collaboration. Persistent contempt, unclear authority, or unwillingness to discuss a serious conflict raises a different concern.

Write down what supports the team case, what remains unresolved, and which unresolved issue could prevent the next milestone. Integrity concerns deserve separate weight. Misrepresenting an advisor as an employee or a possible customer as signed business changes how you interpret the rest of the pitch.

Thoughtful investors can reach different conclusions from the same early evidence, and a promising team can still fail.
