Heavybit is a specialist early-stage investor in developer-first and bottom-up enterprise infrastructure startups: "working with developer tools and bottom-up enterprise software companies is all we do." It backs technical founders "with a unique vision to redefine how teams build, deploy, secure, and scale software," typically leading or co-leading pre-seed and seed rounds. The firm's core belief is that good devtool investing is a craft of specialists who know that timing is everything and that "developers, themselves, aren't 'a business model' but they can be a path to large enterprise sales."
Open on the broad, important problem — an industry truth or trend, then the challenge it creates — establishing scope, value and timeliness before narrowing to your specific solution.
“Your first slide should cover the general problem. As we mentioned earlier, a highly effective approach is starting with a broad challenge that underscores the importance, scope, and value of a potential solution, as well as its timeliness.” — How to Build an Effective Pitch Deck for Devtool Startups
“The most effective fundraising deck not only covers the problem you solve with clear proof points but also covers why your team is most poised to make effective use of capital and capture a market.” — How to Build an Effective Pitch Deck for Devtool Startups
“Be wedded to the problem, don't be wedded to the solution.” — Jim Rose (CircleCI CEO, via Heavybit)
An ideal solution stated in the abstract, then a concrete product slide with screenshots, a demo link, or wireframes — show working software, not just claims.
“If there is, in fact, a problem, what is the ideal, general solution in the abstract?” — How to Build an Effective Pitch Deck for Devtool Startups
“Your product slide should include concrete screenshots if available, otherwise diagrams/wireframes that show your startup's solution.” — How to Build an Effective Pitch Deck for Devtool Startups
“Building and investing in developer tools companies is hard because devtools can be deceptively complex to create and launch.” — Dana Oshiro
A nested/expanding view of the market where each ring is a larger product roadmap, more potential users per company, and more potential customer companies — demonstrating venture-scale headroom, not a single TAM number.
“Each of these circles represents a larger product roadmap and therefore larger value delivered, a larger set of potential users within a company and a larger set of potential customer companies, and therefore dramatically larger potential revenue/addressable markets.” — How to Build an Effective Pitch Deck for Devtool Startups
“Just because you've identified a problem and have a great solution doesn't mean it can be a real business.” — James Lindenbaum (Heroku cofounder, via Heavybit)
“AI is already taking over software development and delivery, with 75% of enterprise teams either using it or planning to by 2028.” — Tom Drummond
A momentum slide that convinces the investor the solution works: activity metrics, developer/practitioner love, customer testimonials, a progress timeline, and KPIs. Show that real users care, not just sign-ups.
“Your momentum slide should include clear examples that your startup is gaining traction, some ways to show that include offering: Activity Metrics, Developer/Practitioner Love, Customer Testimonials, Progress Timeline, KPIs.” — How to Build an Effective Pitch Deck for Devtool Startups
“It's time to convince your audience that your solution works.” — How to Build an Effective Pitch Deck for Devtool Startups
“We went out and got more customers so we could do it.” — Edith Harbaugh (LaunchDarkly cofounder, via Heavybit)
A team uniquely equipped for the challenge with demonstrated experience in both the solution and the go-to-market motion; for AI-native plays, deep founder-market fit (someone who has lived the role being augmented, or who knows how to build for developers).
“Why is your team uniquely equipped to take on the challenge? Use this slide to briefly introduce key team members, their backgrounds, and relevant accolades.” — How to Build an Effective Pitch Deck for Devtool Startups
“For user-down companies, at least one founder must have deep experience in the role they're trying to augment or replace.” — Amir Zohrenejad
“For tech-up companies, I look for founders who know how to build for developers: Great developer experience, smart open-source strategy, and real community building.” — Amir Zohrenejad
“I always talk about the trifecta when you're an early-stage startup, of 'team, dream, and steam.'” — Edith Harbaugh (LaunchDarkly cofounder, via Heavybit)
A clear answer to how you make money and how the model scales; for devtools, an honest read on the bottom-up-to-enterprise path — developers are an entry point, not the business model itself, and you cannot 'back into' developer love later.
“Your go-to-market slide is your chance to prove to investors that you have a business that not only works in the current market but will scale in the future.” — How to Build an Effective Pitch Deck for Devtool Startups
“Developers, themselves, aren't 'a business model' but they can be a path to large enterprise sales.” — Tom Drummond
“You can pursue a bottom-up and a top-down business model in tandem, but no, you can't 'back into' developer love later.” — Tom Drummond
“Create more value than you capture.” — David Crawshaw (Tailscale cofounder, via Heavybit)
A competitive slide that proves you can become the breakout category leader — a competitive quadrant and a credible reason you capture the market instead of an incumbent. For AI-native plays, recognize the real competitor is often a new feature inside an incumbent tool.
“Use your competitive landscape slide to prove that your startup has all the makings of a breakout category leader with: A Competitive Quadrant.” — How to Build an Effective Pitch Deck for Devtool Startups
“How will you capture it instead of someone else?” — How to Build an Effective Pitch Deck for Devtool Startups
“Their main competitor is often just a new feature in an incumbent tool.” — Amir Zohrenejad
“While it may feel like early winners have emerged with strong moats, we're still in the earliest innings.” — Amir Zohrenejad
An explicit answer to 'what has changed / why now' woven into the market slide; a strong, opinionated point of view on a domain, and (for current Heavybit) why AI makes this the moment for new infrastructure primitives.
“Ideally, this slide should also answer the question 'What has changed?/Why now?'” — How to Build an Effective Pitch Deck for Devtool Startups
“Successful startups tend to have a very strong point of view on a particular domain.” — James Lindenbaum (Heroku cofounder, via Heavybit)
“This trend will only accelerate with the rise of AI.” — Amir Zohrenejad
A clear, specific ask: how much you're raising, your deadline to close, and a go-to-market funnel showing how the capital converts into customers. A rough post-money range belongs in the talk track.
“State how much you're raising and your deadline to close. Consider including a rough post-money valuation range in your talk track as well.” — How to Build an Effective Pitch Deck for Devtool Startups
“Show your current or imagined future funnel. How do customers enter the top of the funnel? How do they hear about you?” — How to Build an Effective Pitch Deck for Devtool Startups
“The most effective fundraising deck not only covers the problem you solve with clear proof points but also covers why your team is most poised to make effective use of capital and capture a market.” — How to Build an Effective Pitch Deck for Devtool Startups
“Good devtool investors are specialists.”
“Building and investing in developer tools companies is hard because devtools can be deceptively complex to create and launch.”
“These startups give superpowers to existing technical personas, or aim to replace them entirely, by embedding intelligence into their workflows from the top down.”
