Synastry for Co-Founders
Ever wondered why some co-founder duos seem to finish each other’s sentences, while others barely make it past the first product launch? Sure, business wisdom tells us to look at complementary skills, shared vision, and communication styles. But if you’re the kind of modern professional who’s open to blending practical tools with a dash of cosmic insight, synastry charts might offer an unexpected edge.
What is Synastry—and Why Should Co-Founders Care?
At its core, synastry is the comparison of two natal (birth) charts to see how people’s energies mesh—or clash. While synastry is often used in romantic relationships, its insights are surprisingly useful in business partnerships too. Think of it as a compatibility analysis, but instead of corporate jargon, you’re looking at planetary alignments.
“Astrology won’t make or break your startup. But it can explain why your partner’s risk-taking excites you… or makes you want to hide under your desk.”
This approach isn’t about mystical destiny or blaming Mercury retrograde for missed deadlines. It’s about understanding where your working styles naturally harmonize—and where you might need some extra clarity (or coffee).
Case Study: When Mars Meets Saturn in the Boardroom
Let’s say you’re teaming up with a friend to launch a wellness app. You’re both smart, motivated, and passionate. But after the first investor meeting, you notice tension: You want to move fast and break things; your partner wants to double-check every detail.
You pull up your synastry chart (more on how to do that below) and spot it: Your Mars (action, drive) sits right on their Saturn (structure, caution). Suddenly, your dynamic makes perfect sense. You bring the spark; they keep things grounded. Frustration turns into respect—and you start scheduling meetings that leave space for both brainstorming and spreadsheets.
How to Run a Synastry Chart for Business Partners
1. Gather the Details
- Birth date, time, and location for both people. (Tip: Exact time gives the most accurate results, but you can still get useful insights with just the date.)
2. Use a Free Synastry Tool
- Astro.com: Trusted, detailed, and free.
- Astro-Chart Synastry Tool: Clean and easy interface.
3. Focus on Key Aspects for Co-Founders
- Sun, Moon, Ascendant: General vibe, approach to work.
- Mercury: Communication style.
- Mars: Drive and conflict.
- Saturn: Boundaries, patience, long-term vision.
- Jupiter: Growth, optimism, shared values.
4. Interpret, Don’t Overthink
Look for harmonious aspects (trines, sextiles) for easy collaboration, and challenging ones (squares, oppositions) for potential friction—but also growth. The goal isn’t to “fix” your chart, but to work with what you’ve got.

Real Talk: What Synastry Can—and Can’t—Do
- Can: Help you understand each other’s strengths, conflict triggers, and communication gaps.
- Can’t: Replace vetting for skills, ethics, or business acumen.
“Synastry won’t code your app or land your seed round. But it might help you avoid that 2am Slack meltdown.”
Best Practices for Co-Founders Using Synastry
- Use synastry as a conversation starter, not a final verdict.
- Pair chart insights with regular check-ins and honest feedback.
- Remember: Oppositions and squares can indicate dynamic, creative tension—not just problems!
- Consider a short session with a professional astrologer for deeper context (but don’t let it replace legal or financial due diligence).

- Prepare: Each founder prints their synastry highlights (top 3 harmonious, top 3 challenging aspects).
- Share: Swap notes and discuss one insight that surprised you.
- Plan: Choose one “growth area” to consciously support each other on for the next week.

Time required: 15 minutes, plus a follow-up chat next week.
