End of 2019. Arashdeep's basement near campus. Trying to make music together on Macbooks.
I looked at him and said: "What about building software together? Building an app, building something that's truly amazing and that can potentially change our lives. But most importantly, it doesn't matter if it fails or makes it through—we'd have something that we can talk about, that can help us in our career journey regardless of what we choose."
That pitch changed everything. Not because of what we built, but because of what I learned about why you actually need a co-founder.
The Context That Made It Necessary
In 2019, starting a software company alone was nearly impossible if you couldn't code:
- No AI to write code for you
- No low-code tools that actually worked
- No Claude to one-shot a prototype
- No GitHub Copilot to handle the heavy lifting
Talent was the absolute constraint.
The division was stark:
- Technical founders: Could build anything but struggled with product direction, customer development, business strategy
- Non-technical founders: Had ideas and business sense but couldn't execute without finding a technical co-founder
I was firmly in the second camp.
I had ideas. I understood customers. I could sell. But I couldn't build.
The pitch to Arashdeep wasn't "want to make money together?" It was "I need you because I literally can't do this alone."
What That Basement Conversation Actually Was
Looking back, that wasn't really a business pitch. It was a partnership proposal.
What I was really saying:
- "I have conviction about building something meaningful"
- "I think we work well together"
- "I want someone to go through this journey with"
- "The outcome matters less than having someone to share it with"
What Arashdeep heard:
- "This person believes in something bigger than just making music"
- "He wants a true partner, not just hired help"
- "The risk is shared, but so is everything else"
- "We're in this together, whatever happens"
The basement pitch wasn't about the product we'd build. It was about the partnership we'd form.
The Technical Constraint That No Longer Exists
Today's version of that conversation would be completely different:
2019 version: "I have this idea for [product] but I need someone who can code it."
2024 version: "I built the MVP with Claude last weekend. Want to see if we can turn it into something bigger together?"
The fundamental shift:
- Then: Technical co-founder was mandatory for execution
- Now: Technical co-founder is optional for initial validation
I could build SimpleDirect's first version today with AI in about 2 weeks.
In 2019, that would have taken me 6+ months of learning to code or finding a technical co-founder.
The technical bottleneck that made Arashdeep essential no longer exists.
What I Thought I Needed vs What I Actually Needed
What I thought I was getting from Arashdeep:
- Someone who could write code
- Technical expertise I didn't have
- Ability to build the product I envisioned
- Faster execution than learning to code myself
What I actually got from Arashdeep:
- Someone who pushed back on bad ideas
- A different perspective on product decisions
- Accountability partner who wouldn't let me quit
- Shared emotional investment in the outcome
- Another brain to think through complex problems
The coding was just the surface layer. The real value was everything else.
The Question That Changes Everything
If I could have done it alone with AI, would I have wanted to?
For the code: Yes, AI could have handled it
- Claude can write better code than either of us wrote in 2019
- GitHub Copilot handles debugging better than we did
- AI tools can build prototypes faster than we could
For the direction: No, I needed someone to push back
- My first 12 product ideas were terrible
- Arashdeep talked me out of 8 of them
- The good ideas emerged from our debates, not my solo thinking
- Having someone challenge assumptions led to better decisions
For the journey: Building alone is lonely, even with AI
- Celebrating wins alone feels hollow
- Processing failures alone is brutal
- Daily motivation is harder without shared investment
- AI can help you build, but can't share the emotional weight
For accountability: Harder to quit when someone else is counting on you
- Easy to abandon projects when only you care
- Shared commitment creates persistence through difficult phases
- External accountability drives consistency
- Co-founder disappointment hurts more than personal failure
What That Basement Really Taught Me
The basement pitch worked not because of what we said, but because of what we both wanted:
I wanted: A partnership where success and failure were shared
Arashdeep wanted: To build something meaningful with someone he trusted
Neither of us was optimizing for:
- Equity splits or ownership percentages
- Defined roles and responsibilities
- Exit strategies or investor potential
- Technical skill complementarity
We were optimizing for:
- Shared vision and values alignment
- Trust and mutual respect
- Willingness to figure it out together
- Long-term partnership orientation
That foundation made everything else workable.
The Co-Founder Paradox in the AI Era
AI eliminated the technical dependency but revealed what co-founders are really for:
Before AI:
- Co-founders = skills you don't have
- Partnership = necessity for execution
- Success = finding complementary capabilities
After AI:
- Co-founders = perspectives you don't have
- Partnership = choice for better outcomes
- Success = finding complementary thinking
The question shifted from "Can you do what I can't?" to "Do you think differently than I do?"
Examples of what changed:
- Technical execution (2019): Needed Arashdeep to write code
- Technical execution (2024): Could use Claude, but having Arashdeep review and challenge the approach led to better architecture
- Product decisions (2019): Needed Arashdeep's technical perspective on feasibility
- Product decisions (2024): AI can assess feasibility, but Arashdeep's product intuition prevented building features customers didn't want
- Business strategy (2019): Divided responsibilities - I handled business, he handled technical
- Business strategy (2024): Combined perspectives led to strategies neither of us would have developed alone
The Loneliness Factor
Building alone with AI is technically possible but emotionally difficult:
What AI provides:
- Unlimited coding assistance
- 24/7 availability for problem-solving
- No ego or personal conflicts
- Consistent output quality
What AI doesn't provide:
- Emotional investment in your success
- Celebration of wins and commiseration during failures
- Challenge to your assumptions and blind spots
- Shared ownership of decisions and outcomes
The basement pitch was really about: "Want to care about the same thing I care about?"
That's something AI fundamentally can't provide.
Example from building SimpleDirect:
- Technical problem: Claude helped me debug a complex integration issue in 30 minutes
- Emotional problem: When our biggest customer churned, I needed someone who cared as much as I did to process what went wrong and figure out how to prevent it
AI solved the first problem perfectly. Only a co-founder could help with the second.
What Modern Basement Pitches Should Sound Like
Old pitch (necessity-based): "I have this idea but I need a technical co-founder to build it."
New pitch (partnership-based): "I built this MVP with AI, but I think it could be 10x better with someone who thinks differently than I do. Want to figure out what that looks like together?"
What makes a good modern co-founder pitch:
Focus on thinking, not doing:
- "I need someone who approaches problems differently"
- "I want a partner who will challenge my assumptions"
- "I'm looking for someone who complements my blind spots"
Emphasize partnership, not transaction:
- "We'd figure this out together" vs "You handle tech, I handle business"
- "Shared ownership of all decisions" vs "Divided responsibilities"
- "Long-term partnership" vs "Startup co-founder arrangement"
Address the AI elephant directly:
- "Yes, I could probably build this alone with AI, but I think we'd build something better together"
- "AI can handle execution, but I want a thinking partner for strategy"
- "The technical constraint is gone, but I still want someone in the trenches with me"
The Arashdeep Test
Since that basement conversation, I use what I call the "Arashdeep Test" for evaluating potential partnerships:
Question 1: Would I want to spend 2+ years in the trenches with this person?
- Can we handle disagreement productively?
- Do they bring different perspectives than mine?
- Would I trust them with decisions when I'm not around?
Question 2: Are they optimizing for the same things I am?
- Long-term partnership vs short-term transaction?
- Building something meaningful vs just making money?
- Shared success vs individual advancement?
Question 3: Do they make the product/business better through their thinking?
- Do they see problems I miss?
- Do they generate ideas I wouldn't have?
- Do they improve decisions through debate and discussion?
Question 4: Would I do this alone if I had to?
- If yes, but I'd rather do it with them = good partnership
- If no, I literally can't without them = dependency (risky)
- If yes, and I'd rather do it alone = wrong partner
Arashdeep passed all four tests in that basement conversation.
What We Actually Built Together
The technical product: SimpleDirect evolved through 3 major pivots over 18 months The real product: A partnership model for building companies that survived co-founder separation
When Arashdeep eventually moved on to other opportunities:
- No hard feelings or equity disputes
- Maintained friendship and mutual respect
- Both of us grateful for what we learned together
- Foundation strong enough that partnership could evolve rather than end badly
What that basement pitch really created:
- Shared experience that shaped how we both think about building companies
- Model for how technical and business perspectives can complement each other
- Understanding that good partnerships are about thinking together, not just dividing labor
- Proof that AI can replace skills but not perspectives
The Deeper Truth About Co-Founders
Everyone focuses on the practical benefits of co-founders:
- Complementary skills and capabilities
- Shared workload and faster execution
- Diverse networks and relationships
- Risk mitigation through multiple skill sets
But the real benefit is psychological and strategic:
- Another brain thinking about the same problems
- Someone who cares enough to tell you when you're wrong
- Shared emotional investment in the outcome
- Accountability partner who won't let you quit or settle
The basement pitch worked because it addressed the deeper need, not just the surface constraint.
AI can replace the surface constraint (technical execution) but makes the deeper need (thinking partnership) more important, not less.
hat This Means for Modern Founders
If you're considering a co-founder:
Don't ask: "What skills do they have that I don't?" Ask: "How do they think differently than I do?"
If you're finding this useful, I send essays like this 2-3x per week.
·No spam
Don't optimize for: Complementary capabilities Optimize for: Complementary perspectives and thinking styles
Don't focus on: What they can do that you can't Focus on: How they make decisions differently than you do
The AI co-founder question: "If AI could do everything they do, would I still want to build this with them?"
If the answer is yes, you've found a thinking partner. If the answer is no, you're looking for hired help, not a co-founder.
The Basement Lesson
That basement conversation taught me the most important thing about partnerships:
Good co-founder relationships aren't about needing each other. They're about choosing each other.
The necessity (technical skills) brought us together. The choice (wanting to build something meaningful with someone we trusted) made it work.
In the AI era, the necessity is gone. Only the choice remains.
And that makes finding the right co-founder both harder and more important.
Harder because you can't use skill gaps as a filter. More important because thinking partnerships will differentiate successful companies from solo efforts that plateau.
The best basement pitch today isn't "I need you." It's "I choose you."
That's what Arashdeep and I were really saying to each other, even though we didn't know it at the time.
The basement pitch that started it all wasn't about building software. It was about building a partnership that could figure out how to build software—and everything that came after.
