Competing with giants, the end of SaaS & other listener questions

REWORK host Kimberly Rhodes asks 37signals co-founders Jason Fried and David Heinemeier Hansson whether agent-built custom software will end SaaS. They see the near-term threat as uneven: expensive, disliked enterprise deployments are exposed, while most low- and mid-market customers still pay vendors to own the maintenance, operations, and product decisions.

Key Points Covered

• Compete for a viable niche, not to defeat a giant: Fried tells small builders to focus on their own costs, customers, and reason to exist. The immediate test is whether a few customers will pay, not whether the product can displace Google or Apple 01:02–03:04(opens in a new tab).
• Use smallness as differentiation: Hansson suggests asking whether you would buy your own product over the established alternative, then leaning into advantages a large company cannot copy, such as direct access and a narrower, more distinctive product 03:04–05:12(opens in a new tab).
• Replacing SaaS with agents is still pioneer behavior: Hansson says most examples he sees come from people who already want to experiment with agents. He sees greater near-term exposure in expensive, disliked enterprise systems than in inexpensive tools for small companies 05:12–07:55(opens in a new tab).
• Buying software transfers operational responsibility: The barrier is not only building a replacement. Customers must run it, maintain it, manage its data and backups, and preserve ownership when employees leave. Hansson points to limited uptake for 37signals' self-hosted ONCE products as evidence from their own business, not a market-wide measurement 07:55–09:42(opens in a new tab).
• AI adds another competitive option rather than creating churn from nothing: Fried notes that customers already switch because of competitors or weak products. Agent-built tools add one more alternative, so vendors should assess their actual price point and customer segment instead of treating SaaS as one market 09:42–10:44(opens in a new tab).
• Build-versus-buy economics still matter: Fried contrasts a hypothetical million-dollar replacement with recreating a product that costs $600 per year. Even with agents, employee time, maintenance, breakage, and opportunity cost can exceed the subscription while leaving no vendor accountable for support 10:44–12:47(opens in a new tab).
• Implementation is only part of a product: Fried argues that strong software still needs a cohesive concept, boundaries, and an understanding of what customers are trying to accomplish. Faster code generation helps established vendors too; it does not remove the product work 12:47–14:30(opens in a new tab).
• The larger shift would be agents choosing the solution: Hansson distinguishes implementing a customer's request from diagnosing the problem and deciding what software should exist. He has not yet seen autonomous product direction work well; his strongest examples still require a person with taste, vision, and domain knowledge to steer agents 14:30–16:38(opens in a new tab).
• Cheaper implementation creates new human competitors: Hansson sees a nearer-term threat in people who already have product taste and ideas but previously lacked programming ability or funding. Agents let more of those builders turn their ideas into working software 16:38–18:29(opens in a new tab).
• Personal presence works better when it is not manufactured: In the final question, Fried and Hansson reject formulaic “personal brand” tactics in favor of talking plainly about work and interests. Hansson also acknowledges the tradeoff: ordinary corporate social accounts often attract little attention, forcing founders to mix personal and company communication 19:29–27:50(opens in a new tab).
