AGENTS CAN NOW SIGN UP FOR YOUR APP

Agents are hitting your signup flow and bouncing off a browser login built for humans. Every one that gives up is a signup you never see. WorkOS Agent Registration [5] turns that traffic into signups. Enroll via the dashboard and AuthKit publishes an auth.md file agents read to register for scoped, short-lived credentials you control.

03STRATEGIES & TACTICS

FIRSTHAND: HOW I BUILT A BRAND WITH HEART AT LOVABLE

Lovable launched in late 2024 with a visual identity that was prototyped in 30 machines. The brand quickly picked up $10 million in annual recurring revenue just 60 days after launch. Lovable's brand was designed and redesigned over two and a half years by an insanely talented design team. This post tells the story of how Lovable's first designer translated a feeling of genuine infectiousness into a design brief and brand identity. The company's growth shows what is possible when people with innate curiosity and genuine care for what they do are given complete trust: they produce exceptional work, remarkably fast.

THE ONE SALES MOVE THAT DOESN'T ASK YOUR PROSPECT FOR ANYTHING

Commenting on your prospects' posts can create investment while adding value. Comments create a direct touchpoint with your prospects, and it works as a distribution to many more similar prospects. They allow you to get free reach into a network of people just like your buyer. Commenting lets you stay visible in a way nothing else in outbound can.

RAISING YOUR NEXT ROUND IS HARDER THAN YOUR LAST ONE. HERE'S WHY

This post lays out the arithmetic behind why a company that raised a seed easily gets Series A nos without changing anything about itself. An accelerator writing checks at $330K to $2.5M post-money only needs a $33M to $250M exit to work. Your seed at $5-10M post requires belief in a $500M to $1B outcome, and a Series A investor underwrites a path to roughly $100M a year, which is why $1M ARR is not enough. Dilution eats 50%+ by exit. Three escape valves get named, including customer-funded growth and capital that does not need 100x.

04TOOLS & RESOURCES

CODING SESSIONS: ENVIRONMENTS, BROWSER USE, AND UPDATED PRICING

Linear Agent can now set up, run, and test code before returning its work. Coding sessions now automatically adapt to each codebase's configuration. Once the application is running, Linear Agent tests it in the browser, where users experience it. If the agent finds a problem, it can make a fix and rerun the test before returning the work. Linear has also introduced more transparent pricing and made AI credit usage easier to understand and control.

SLACK CODE

Slack Code creates temporary channels where teams and agents can work together on a specific task or project. The channel is archived automatically when the work is done, but the context remains searchable. Code channels follow Slack's enterprise-grade security and permissions model. They make it easy for anyone, even non-technical employees, to see what an agent is building, review previews, and share feedback directly in Slack.

TECHNICAL INGREDIENTS, REVENUE INGREDIENTS

Shipping code is not the same as shipping revenue. Confusing the two is an unforced error. If you haven't prepared great market-readiness ingredients, you just have another unsellable software. CEOs need to identify the next revenue to bottle next when code development is faster than selling.

FORGET ABOUT THE ARR

AI acquisitions require code-level diligence because ARR and growth cannot reveal whether proprietary technology is defensible or merely a model wrapper. Buyers should score model dependency, data moat, talent concentration, and substitution risk before signing or assigning premium valuations.
