Marketplaces are tough businesses, but after about two years, they hit an inflection point and start growing exponentially.

PayPal's growth was driven by its two-sided marketplace, connecting buyers and sellers, and its viral mechanism through eBay.

Payment networks function as marketplaces, and while they are challenging to establish due to the chicken-and-egg problem, once solved, they can create very sticky businesses, as seen with successful companies like Airbnb and DoorDash.

Many successful tech companies, like Amazon and eBay, began by dominating a small niche before expanding into larger markets.

The current tech landscape is characterized by a few dominant players that are reshaping entire industries, leading to a significant concentration of market power.

Marketplaces like Science Exchange need to be the platform that companies use for all their projects, not just a one-off shopping experience, to be truly effective.

The internet has created a giant aggregator for information, leading to a few dominant platforms while eliminating medium-sized entities. This results in a landscape where a few large media outlets exist alongside countless independent voices.

Market dominance can be achieved through three strategies: best price, best product, or best overall solution, with the latter being accessible to any company willing to prioritize customer intimacy.
