About Flipturn
Flipturn is a modern EV charging and energy management platform for fleets, multifamily properties, and charge point operators. Founded by MIT, Samsara, and Stripe alumni, the company has raised over $15M in venture funding from CRV, Accel, and others.
Customers include Republic Services, FedEx, and the City of Seattle. The team is about 20 people, with a 10-person engineering org led by CTO and co-founder Sashko Stubailo.
Code Review
At Flipturn, engineers take their pick from an approved list of AI tools. Team members use Cursor, Claude Code, and Indent side by side, and keep a close eye on new tools to evaluate.
"It’s important for us to preserve the ability for individual engineers to work in the way that makes them most productive. That makes Indent's life pretty hard, because we’re evaluating ways to improve our workflow every day. The fact that we're continuing to use Indent very actively is proof that they're doing a really great job."
Sashko Stubilo, CTO & Co-founder, Flipturn
When Flipturn started using Indent, the team had already learned to ignore feedback from other AI code review tools. In their experience, these tools generated comments too generic to be useful.
Indent's reviews were substantively different. Instead of flagging style nits, Indent catches inconsistencies with patterns elsewhere in the codebase and suggests approaches that reflect a real understanding of the project.
"It's often bringing up suggestions that aren't necessarily bugs, but more like, 'Hey, in a different part of the code base, you're doing this another way.' That was above what we expected an AI code review tool would be able to do."
Sashko Stubilo
Now, on more than half of Flipturn's pull requests, Indent makes a suggestion that gets applied.
Coding Agent
Because Indent's code reviews demonstrated a deep understanding of Flipturn's codebase, the team wanted to see whether it could write code as well as it could critique it.
The team has found Indent can often finish a task in the time it takes Cursor to start up, which meant engineers started reaching for help on a broader range of tasks. Indent's low overhead makes it possible to spin an agent up in parallel for a small PR update, a quick question about the code, or a minor fix.
Flipturn makes heavy use of Indent from within Slack threads, so the engineers working on a problem and the work being done to fix it is visible to everyone involved through a single interface.
"Being able to call Indent directly from Slack and have a conversation is really important to me. Different team members can see what's going on because we're often collaborating on an issue. Indent becomes almost like a partner in that conversation versus somebody going off in a hole for 20 minutes."
Sashko Stubilo
With a day or two of additional setup, the Flipturn team set up Indent to run a fresh build of the full application in the cloud with fake data. It can make a change, run the app, take a screenshot, and post the screenshot back into Slack to show off what it built. Flipturn had already invested in making their dev environment easy to spin up from scratch, and Indent benefits directly from that work.
Alert Triage
Indent also monitors Flipturn's Sentry and Datadog alert channels in Slack. Every error gets an immediate first-pass diagnosis, so engineers can quickly figure out whether it's a real issue or noise, what line of code is involved, and whether it's worth investigating.
Indent diagnoses roughly 60–70% of incoming issues on the spot, and for the issues that do require human attention, engineers to collaborate with Indent to deploy a fix in less than 30 minutes.
Indent's integration with Flipturn's CI and monitoring systems makes more complex investigations possible too. When Flipturn suspected their CI provider was still having issues days after a supposedly resolved outage, they asked Indent to pull a month of build data for analysis. Indent confirmed the problem in minutes, saving the team the context switch and manual effort of digging through the data themselves.
By The Numbers
Indent went from zero commits on Flipturn's main branch in mid-December to being an active contributor by early February, then doubled in commits per week by mid-March, accounting for roughly 35–38*% of all weekly commits.
And human-only commits grew over the same period by 35%. Engineers are shipping more overall, as Indent absorbs more of the work that stood in their way.
What's Changed
The team has found that Indent reduces the friction for smaller fixes. When you can just tag Indent in a Slack thread, customer feedback that previously would've sat in the backlog, rare bugs, and minor UI inconsistencies all start getting addressed more quickly.
"If there's a small customer feedback item, or a bug that comes up really rarely, maybe we would have deferred a fix until later. But if it's as easy as just tagging the bot in Slack, you may as well see if it can handle it. And a lot of the time, it does."
Sashko Stubilo
Engineers can diagnose and resolve issues after hours without pulling out a laptop, cloning a repo, or running the application locally. A minor problem that surfaces at 9pm might otherwise wait until the next day. With Indent, it gets diagnosed and resolved in a thread.
Why Indent Sticks
Sashko can't promise Indent does something no other tool ever will — the space moves too fast for that. But it keeps winning the daily evaluation.
"After working with Indent, I now believe there's no reason to have a separate product for code review, coding, data analysis, and alert triage. I can just use Indent for all of these, and it has the same shared context, skills, and knowledge. Any time I spend configuring Indent helps with all those areas, versus configuring Cursor, which doesn't help me with investigating alerts, PR reviews, or similar tasks."
Sashko Stubilo
Team members have started using Indent for more than just engineering tasks, describing it as "a really amazing coworker experience.", especially with how it’s integrated into their Slack workspace.
This breadth of adoption reflects something specific about how Indent works. When the team invested time configuring Indent for code review, Indent got better at coding. When they connected Indent to Slack, alert triage became possible, without any additional setup. Every hour spent teaching Indent about Flipturn's codebase, infrastructure, and workflows pays off across every surface.
Sashko and his team keep trying other tools, but in his words, "I think Indent is the only one I've tried that has the legs to be a general agent."
