About Carl
Carl Edward Sagan was an American astronomer, planetary scientist, and science communicator. He served as an assistant professor at Harvard University before moving to Cornell University, where he held the position of David Duncan Professor of Astronomy and Space Sciences and directed the Laboratory for Planetary Studies. Sagan contributed to notable space missions including the Mariner, Viking, and Voyager programs, and published over 600 scientific papers and articles. His popular science works began with The Cosmic Connection and include the bestselling book The Dragons of Eden, which earned him the Pulitzer Prize for General Nonfiction. Sagan co-wrote and narrated the acclaimed 1980 documentary series Cosmos A Personal Voyage, which reached an audience of at least 500 million people across 60 countries and received two Emmy Awards as well as a Peabody Award. He was a passionate science fiction fan, with his novel Contact adapted into a film. Sagan was a founding member and the first president of the Planetary Society. He proposed the Pale Blue Dot photograph of Earth taken by Voyager 1 and contributed to the development of messages intended for potential extraterrestrial intelligences such as the Arecibo message, Pioneer plaques, and Voyager Golden Record. An advocate of skepticism and scientific inquiry, Sagan popularized the scientific method and critical thinking, famously stating that extraordinary claims require extraordinary evidence. Throughout his career, he received numerous awards including the NASA Distinguished Public Service Medal and the National Academy of Sciences Public Welfare Medal. Sagan passed away in 1996 at the age of 62 after developing myelodysplasia.

FAQs
Every question we get asked before
someone starts their trial.
If you have a concern about deliverability, AI quality, data privacy, or whether this will actually work for your specific situation, it's probably answered below.
What is the difference between Founder Solo and Founder Pro?
Founder Solo gives you 50 AI pitches per month using the credit model (Standard pitches cost 1 credit, Enriched pitches cost 2). Founder Pro raises that to 200 credits per month and adds full Booking Probability access, unlimited Magic Match, Apollo enrichment credits, and data export capabilities. Both plans use the same credit system, so you can stretch your monthly budget further by using Standard-mode drafting.
How do agency tiers work?
Agency tiers have no base fee. You pay per managed client and per talent profile. Agency Standard is $199 per client per month; Agency Pro is $399 per client per month. Both add $39 per talent profile per month. Your own team's user seats are always free.
What is a talent profile?
A talent profile represents one person (founder, executive, or spokesperson) you are booking onto podcasts. It includes their bio, topics, headshots, and outreach history. Team plans include 5 profiles; agency plans are pay-as-you-go.
Can I switch plans later?
Yes, at any time. Upgrades take effect immediately; downgrades apply at the end of the current billing period. Contact support if you need help migrating between plan families.
Do you offer a free trial?
Every paid plan includes a 15-day free trial. Your card is saved at signup but you will not be charged until day 16. Cancel any time from your dashboard.
What happens if I cancel?
You keep access until the end of your current billing period. No charges after that. Your data is retained for 30 days in case you reactivate.
Is the 20% annual discount automatic?
Yes. Select Annual on the pricing toggle and the discounted price is applied automatically at checkout. The annual price shown is the full year cost.
What if I have more than 50 profiles or 20 clients?
That is our Enterprise tier. Contact our sales team and we will build a custom plan with volume pricing, a dedicated account manager, and SLA guarantees.
