2026.07.06·unsung.aresluna.org·4 min read·TLDR Dev Software spend is accelerating. However, valuations are collapsing for many software leaders. The software market has split in two: one group is tapping AI budgets and accelerating, and the other is running the same playbook from 18 months ago. This post breaks down where the line between these two groups falls and what moves a company from one side to the other.
53% of finance-room executives name proving ROI as the main blocker to further AI spend, 62% expect measurable return within six months, and 17% already fund AI partly from money that would have gone to headcount. Founders in the same network price 50% on usage and 18% on outcomes against 25% on seats, but they still sell through CIOs and business units while the CEO signs and finance carries the proof burden, which is where deals stall. If your product needs eighteen months to show value, you're selling to a buyer who wants evidence in six.
Near-peers are people so good that the founder would be fine reporting to them if the roles were reversed. Their strengths perfectly complement the founder's strengths. Near-peers turn the founder's vision into daily operating decisions. This lets the founder focus on what only the founder can do, while the near-peer handles the rest.
Segmenting churn into categories allows founders to separate different churn problems and solve them individually. Keeping big customers happy is different to keeping small businesses from seeking a cheaper tool. Instead of excluding trials and POCs, segment them out and figure out how to convert better. Also, segment NPS and CSAT per segment - double down on the happiest segments and the segments growing the fastest.
Churn depends on your category. Not all churn is bad. However, some types can kill your business. Once you know your sticky ideal customer profile, the product job becomes to build for them ruthlessly. Free plans activate, and paywalls monetize. Negative churn is the Holy Grail.

Successful creator businesses often evolve from selling content to selling access to the creator's judgment and expertise. Structure access through content, workshops, communities, and premium advisory services rather than offering unlimited founder availability. Founders who want to build a sellable company must gradually shift trust from themselves to the team, brand, and systems.
Churn models ship with a default 0.5 threshold. This analysis prices that default at about $86 per customer in avoidable spend, $8.6M across a 100K-subscriber base. Missing a churner costs about 13x more than over-treating a loyal customer, so the profitable threshold sits well below 0.5 and the default is quietly setting your retention budget. Library defaults across an analytics stack are business decisions nobody consciously made.
Understanding human nature is the highest-leverage skill in an AI-driven world because attention, persuasion, trust, and value creation ultimately depend on people, not technology.
Entrepreneurs mistakenly believe a great product will sell itself without active sales and marketing efforts.
AI has shifted outbound from list-blasting to structured, multi-channel campaigns that combine agents for scale and humans for high-value relationships.
Digital publishers are getting squeezed from both sides. Meta is prioritizing creator content over publisher links, cutting ad revenue, while Google's AI Overviews reduce search traffic by answering queries directly. Some publishers report CTR drops as high as 89%. Search traffic is projected to fall over 40% in three years, after steep declines from Facebook and X. A new UK ruling allows publishers to block Overviews without losing search rankings, adding leverage.
AI hype is sweeping advertising, expectations are overblown. Fully automated ad creation isn't realistic and risks hurting the ecosystem. Like programmatic before it, AI won't replace human judgment. Its real value is improving productivity and workflows. Meanwhile, creators are becoming full-stack businesses, blurring lines with agencies. The industry is shifting toward data-driven marketing, but AI alone won't deliver the transformation many expect.
Placing key customer proof in your website footer can influence how AI systems describe your product. In a test, Clay surfaced its case studies in the footer, and ChatGPT pulled listed customers directly from those links when asked which brands use the product. Companies that bury case studies deeper on their sites were cited far less.
Most loyalty programs fail because they're barely visible. Email flows should surface points, rewards, and status in welcome, post-purchase, and ongoing campaigns. Subscription flows should reinforce value with milestone updates and highlight what's lost during cancellation. Landing pages should surface perks upfront instead of burying them in footers. Retail experiences should connect online and in-store so that earning and redemption work both ways.
Use Google Ads audience targeting as a filter to reduce invalid clicks when click fraud is hurting your campaign performance. One account cut its invalid click rate by 50% after adding hundreds of Google predefined audiences and setting them to Targeting instead of Observation. The approach limits ads to users who match both keywords and Google's audience signals. It works best for accounts with unusually high invalid click rates because it can also exclude legitimate users who do not fit Google's predefined audiences.

ContentGrapher provides website content recommendations for AI visibility. You give it a URL, and it maps weak or missing concepts, how well you've connected certain concepts, and if there's anything that belongs on its own page. It's free for the first 5 analyses, then starts at $29.
Success is framed as a function of what tradeoffs can be sustained, not just strengths or effort. Kristen Lowe introduces “success currencies”, highlighting costs like risk, rejection, and uncertainty as key drivers of achievement. The session includes a self-assessment to identify which costs drain or motivate, and whether current ambitions align with the prices required to reach them. It will take place on July 8 at 9 AM PT.
Google's new system targets coordinated AI content, not individual pages. It detects clusters of accounts producing templated content at scale using shared infrastructure, velocity, and semantic patterns, then removes the entire network. This shifts enforcement from optimizing single pages to avoiding detectable production patterns. High-volume, templated strategies are now a liability.

Legalization of quieter supersonic flights doesn't guarantee a successful comeback for commercial supersonic airliners - Concorde's massive fuel consumption made it difficult to sustain profitable operations.
